So I'm thinking of doing some research and some bulk purchasing from various companies to put together an awesome kit for an in-car computer system.

The in-car computer will completely replace your existing stereo, providing music/video, GPS, bluetooth (to sync with your phone, or whatever you want), 3G and real-time data from your nissan consult, all running off either a double-din, or fold-out single-din touch screen.

O/S will be a lightweight Linux distro optimized for touch screens that will have multi-tasking capabilities (so you can run GPS while you play music with minimal lag/problems). I haven't thought about DE's or WM's but even panels/docks, but a pypanel+openbox like setup seems to go alright.

Anyway, what do you guys think?

Would anyone be interested?

They will come as a DIY kit, or I could install it for you. I'll get all the parts I need and do a demo in my car before I start selling.

yeah I've just started looking into it...

iPad 2 FTL... and nissan consult looks like it might cause some problems. Thinking about Windows running centrifuge.

Compared to other car manufactures systems, this is inferior, but there isn't much you can get for a Skyline.

Just out of curiousity, Troy... in what way do you feel I'm behind the curve? Just so I know where to improve on.

Edit: when I say "iPad 2 FTL", I mean you're looking at a $700+ system that will require an existing head unit to link to the incar speakers. It's better to have a cheap, built-in computer running a lightweight distro of some description (windows, Linux, haven't looked into it so I can't say 100%... btu Windows touch-screen compatibility is pretty good).

That said, the system I'm building will probably cost more than an iPad, but itll be cusotmizable and extendible.

CarPC is lots of effort. But you could have a potentially superior product in the end.

But here are some pointers that may assist.

- Most importand is a good quality 12v to 12v PSU with time delay and some sort of battery power for shutdown sequence - this is because of voltage not being so stable in the car.

- SSD for the OS and main software is a must

- OS wise I'd go Windows 7 - Reason being its just easier for anybody to work on it and you will have less issues with drivers - so much more support or run Windows CE for fast startup/shut down (http://www.microsoft.com/windowsembedded/en-us/evaluate/windows-embedded-automotive-7.aspx)

- Aim for a fanless design, ensure it will operate in extreme heat

- Try to have a system that can process 1080p video.

- Having a touch screen is a must have - and it must also be able to function in the Australian heat.

- Must have bluetooth so you can use a smart phone as your connection to the internet.

- You will need an external usb tuner for radio, tv, GPS

- You will still need an external amp for sound.

Thanks heaps mate! I didn't think of the power thing... would have been a crossroad later. Probably be better to go for a battery-powered device that hibernates when the AC is removed, then turns off when the battery get's to 50% or less.

Automatic power on will be interesting...

Windows CE sounds alright... I don't really think very highly of it. I'll have to research it more...

Fanless design is piss easy, and I'll find a touch screen that works fine no worries. I was going to throw in a 3G dongle, and set the computer up to use it. It'll require a sim card, but you can easily put it in and dial up to your interwebs. that could be an optional extra lol but bluetooth will definitely be in there so people can take calls from it.

Didn't think of radio... lol... I'm going to need to be able to control the antenna too hmmm... interesting.

Yeah amp is a definite.

Some thoughts that come to mind; 1080p video playback will a gfx card of some description.. I was thinking of running an intel atom processor. If I beef it up too much, you'll see an increase in price. I'll go over my options with small-form PCs and their processors VS cost, but yeah, it'll probably be best with 720p video.

I'm looking around for a device with a disk drive.. not very successful -.-

Big project is getting bigger haha

I've been doing the carpc thing for going on 10 years now, and I'm onto about my 3rd or 4th major re-design. I suggest for you hop over to http://mp3car.com for a whole forum dedicated to this stuff.

I'd pretty much agree with everything iseekool has said other than the comments around SSD & fanless. I will admit the price of SSD is a lot cheaper than the last time I built a carpc, but it's still probably un-necessary, and probably means you're going to need a second drive for storage. You can happily use very large 2.5" laptop hard drives (I've done so for many years without issues, within 20cm of a pair of 12" subwoofers - they never skip a bit (Do make sure you get 7200rpm for performance). I personally haven't found fans a big of an issue; you definitely need to make sure the machine gets plenty of ventilation. The last thing you want is the carpc shutting itself off on a 10+ hour interstate drive because it got a bit warm when you have a lot of luggage in the boot.

I use a cutdown Windows XP build (it boots quicker than 7), and centrafuse. It's using an Intel D945GCLF2 motherboard (dual core atom 330) with 2GB of RAM, and a 500GB 7200rpm 2.5" laptop drive, BU-353 GPS. Up front I'm using a xenarc touchscreen with in-built DVD drive. This item is probably my only bugbear, and probably the only component I'd change right now (move to an optically bonded sunlight readable screen).

Whilst I can't do full-screen 1080p playback, the screen doesn't fit 1080p on it anyway (and you'd be hard-pressed to tell it's 1080p vs 720p on a 7" screen anyway). I'm more than happy with the 720p I get with the onboard GPU.

With regards power-supply, I use an M2-ATX 160W intelligent power-supply. It has all the 12V -> ATX power options you need - auto-start-up, auto-shutdown, amplifier activation (you could use this to activate an antenna, if you used a relay, but then it would be up all the time the carpc was..), etc.

I don't really bother with bluetooth, I don't talk on the phone in the car, and I never listen to the radio so I haven't bothered there either. I used to use a 3G dongle to get internet, but given how rarely I'd use it, I stopped - it was just a waste of money. I could probably easily do something with bluetooth/wireless to supply internet to the carpc from my phone, but eh - as above. It's not a feature you need/use much in my experience.

Great insights Jenna. We can all benefit from your experience in this field.

www_Sticker_Tk_kiss_my_ass.jpg

@JEnna; thanks for your insight.. I'll definitely be in contact with you about the project :)

A couple of things... computer in the boot is interesting; I was going to mount behind the dash. The boot sounds like a better idea, and opens me up for case mods that integrate with my planned sound system. I like your thinking :D

1080p; thanks for bringing up that point. I was thinking the same thing about not telling the difference between 720 and 1080, but largely because the screens that are available won't be able to display things like a samsung TV would. Didn't think about aspect ratio either... But that doesn't impede on the design of the system as all screens are essentially going to be 7" i believe.

I want to keep slightly updated with Windows, but I'm worried about the demand win7 would have. If it came down to it, I was thinking about a trimmed down version of XP i found on a torrent site not too long ago if Windows CE didn't do as I wanted.

I was hoping for an android powered system... that would be amazing... but too limiting.

Agreed about lack of use with 3G... I was just thinking of an all inclusive system.

Thanks for the recommendation aobut the psu too, i'll look into it.

I was thinking about making the antenna usb-powered and custom write something to pop it up... not 100% sure how as I haven't had experience, but I was going to see what Ic ould do... HMMMMMMMMM exciting projects are ahead. ><

Another possible solution (ugly).

Buy a decent laptop + docking station.

Have the docking station mounted in your boot with all the accessories (tuners, GPS dongle, in-cabin touch screen) connected to it and the audio routed to a head unit with aux-in or a dedicated amp.

The docking station is then wired to a DC to DC transformer to "up" or "down" the voltage from the car's 12V system.

Cost wise this will be much easier IMHO.

100% agree with the above. My first CarPC experience was done exactly this - notebook with docking station along with a super-cheap chinese indash touchscreen. When the computer saw the mains loss, it was set to power-down. If you're just starting out, this could be an easy approach. It also has the benefit of having all of the parts designed for that sort of scenario, and if something goes wrong, you can pull out the notebook and it has it's own screen to fix it. Also has a lot of the fancier stuff like bluetooth, wifi, etc built-in. I had audio on mine routed to the aux-in on my headunit which then routed to the amplifiers. It all worked surprisingly well.

+ the joy of 1 to 2 year warranty that comes with the notebook, the event it breaks down :)

I was very keen on exploring this idea, especially considering the capabilities of today's mobile tech such as tablets and eeepc's etc. After looking into the idea somewhat, I just went with a JVC double din that has ALL the functionality listed above (bluetooth, GPS, video, radio, ipod etc) Only thing it lacks is web browsing (which I use my smart phone for) hi-res video support and the inability to read anything other than FAT32 which limits storage capabilities. At the end of the day it looks flush, runs off factory power and has more functionality than I need. It's a glorified mp3 head unit for the most part :rolleyes:

Unless you are using it in a car holiday car, I don't think the effort (and cost) to set up a CarPC is worth it tbh. However, I definitely see the attraction and 'cool' factor with such a project and would be keen to see some outcomes =)

yeah I've just started looking into it...

Compared to other car manufactures systems, this is inferior, but there isn't much you can get for a Skyline.

Just out of curiousity, Troy... in what way do you feel I'm behind the curve? Just so I know where to improve on. (the reason I say that is most people cant' fiddle with linux or even window 7 when a driver fails to load so its not user friendly) You can run a security risk of over running your 3G/wifi connection if you get hacked costing you a mountain of cash , it takes a few min to hack into a system and reset all the accounts /passwords.

all the little bits that plug in to the system creates missmatch signals output and voltage issues , computer audio isn't setup to punch car amps to a max volume without a pre amp.

the Ipad/Other tables can bluetooth your Consult cable wireless. app and hardware exists already for nissans. you have access to all the sensors and can even reset warnings on cars that have service lights etc.

you dont need a head unit for Ipads or Iphones, only a break out cable to charge and output video, audio digtial /analog ,

Ipads are dummy proof lol

you can make them to be removed in shady areas with a fake factory radio as a back plate to hide the fact you have a big setup . you dont' need to run Harddrives, but you can run a wireless one in the boot with a few Terabytes of movies.music .

you instantly have 3G/GPS tracking device with Ipads. if you buy the top models.

you can stream off your iphone to ipad. you can turn on the camera on the ipad remotely out of the box to video your thief at the wheel.

you have a G sensor built in to the ipads.

you have HD video , if they unlock pandora app for australia things would be even better. but you can use another similar app

the ipad and parts take up very littel space compared to a incar pc.

you can control your car alarm with app.

I did use a laptop with all the bits in the past running a XP cut down and Media interace to a head unit ... and Jenna has a setup that works, but both of us as extensive IT knowledge . and it wasnt a quick process to setup

I just find its a lot more work and can get fussy if a person installs it wrong. engine noise is a huge issue in most cases.

apple is more secure so far.

and can be used outside the car for a lite laptop if you make it removable ?

I just think a incar pc is beyond most average installers , so unless your going to install it as well. its going to be a nightmare . cost wise it just doesnt make sense to put a car pc in . when nice double din head units cover most needs . and the tablets cover the rest .

Edit: when I say "iPad 2 FTL", I mean you're looking at a $700+ system that will require an existing head unit to link to the incar speakers. It's better to have a cheap, built-in computer running a lightweight distro of some description (windows, Linux, haven't looked into it so I can't say 100%... btu Windows touch-screen compatibility is pretty good).

That said, the system I'm building will probably cost more than an iPad, but itll be cusotmizable and extendible.

^ Good point. iPad (or even any other tablet) could be a good option come to think of it.

Going off topic slightly - I don't own an iPad or any other tablet.

Does iPad have software you can stream audio/video from any shared network drive?

I would assume theres an app for it. Tablets would be a good compomise between a media pc and notebook, but you would be limited to apps only.

What would be your choice of wireless stream? My head deck streams bluetooth from my phone and it struggles with higher bitrate MP3's

With the iPad software... Is this compatible with Nissan CONSULT yet?? I know there is tonnes of OBDII support around, but hadn't found anything that will connect to CONSULT yet?

Not that I've really been looking, I use NIStune myself. Just a bit interested if Apple or any other software makers would cater to the minority needs of Nissan drivers wanting to connect to their CONSULT port.

There is a couple of apps, very frustrating it isn't standard :domokun:

Interesting project, I'll keep an eye out. I would have loved a blu-ray player in my car, not so much so I can watch HD, but so I can watch all the movies I've got on blu-ray, even if it is downsampled to 720p. This sounds like it has the potential to give me that ability, so keep us posted! :thumbsup:

you can use a blue ray player out of a PC in a car, easy to mod

most APPS use bluetooth dongles to get info , its very common in north america magazines , on 350Z and 370Z and canadian imported Skylines

    • Hi everyone, I've found some free time to write up my "build thread" which is 10% 'build' and 90% fixing problems of a skyline that has endured a lifetime of abuse. I will start with the backstory & get everyone up to speed. Ever since I was just a teenager in high school I have had a spot in my heart for the shape of an R32 rivaled only by the look of an S13, my mates & I all having overly ambitious dreams as one does about having the sickest car in the school carpark. Unfortunately I started my journey of cars down the path of the Silvia and after spending years of putting up with the underwhelming SR20 life I dipped my toes into the 1J Toyota pool for a small moment until my true compass brought me back to that incomplete dream of an R32. At this point the trawl through marketplace, gumtree, carsales etc. starts looking Aus wide for an affordable example in the current economy which was extremely barebones compared to the good old days of sub 10k cars everywhere. Out of the handful of cars in the budget at the time I settled on a 1992 R32 GTS-T that was located in Adelaide. It had caught my eyes as it was similar price to the others on the east coast and had been RB25DET NEO converted and an open door respray in a custom colour based off TH1. It was also a stand out to me because it already had some NSW registration left which saved me the hassle of getting it on the road in my state. As for mods I was told it was pretty stock other than the motor swap, a nistune to run it, and an unknown fuel pump. My first mistake was trusting the seller blindly that the car was in good condition in all aspects and decided to purchase the car unseen other than some walkaround videos & pictures as the flights down there were very expensive at the time. The price of getting it transported to my door from Adelaide from Sydney was surprisingly cheaper than the flights at the time. I was told the few issues it apparently had was only 1 speaker not working, some cracked or missing trims, and it had been rear ended at some point but had been all professionally repaired (this is all foreshadowing at this point). I paid for the car, and then booked the interstate transport. Now at this point save your criticism as I already know how stupid I sound in hindsight, this was a major lapse of judgement and I accept the problems that followed. I spent the next 2 weeks in a crazed excitement knowing I am finally the owner of an R32 & that it was on its way. I started preparing as when negotiating with the seller I opted out of the Lenso wheels as they aren't really my style & I wanted a set of genuine wheels, and the bucket seats in the car as I am 6ft5 and not the skinniest guy so I had my predictions that I wouldn't fit in them anyway. Due to this the car was put on a set of R33 stockies and some average condition R33 seats that he had laying around. While I waited for the car to arrive I went and picked up a pair of R32 seats and some R32 GTR wheels to fit nicely on it once it had arrived. Being the first time I had done anything like this or had a car transported interstate I had no clue how the logistics of it were, I chose my work as the delivery address assuming it would arrive at some point in the middle of the day. You can imagine my surprise when I wake up to a call from the truck at 5:30am telling me his about 20 minutes away. When I tell you that was the fastest drive to work I have ever done, I managed to catch up to the truck before it even got there. Spent the hours before work taking in the car and living my first experience with one, I had never even been inside one so I spent some time getting familiar with the interior before doing the seat swap. Here is my first proper photo of it as the sun rose in the background. I also noticed it had the switch for the electronic front lip which was a pleasant surprised but sadly upon looking it didn't actually have the lip or the motors or even any wiring behind the switch. As I swapped the seats, the extremely questionable history of the car started to show itself starting with some really dodgy seatbelt buckles that had been extended for some reason with horrendous welds. This was followed by me noticing the drivers side front was quite bent up to which the owner then decided to let me know it had been hit in the front at the same time as the rear end. It also had a pretty leaky power steering rack and the pump was screaming for its life. By now I was a little on edge but I had to get to work for the day, I sent the car down to my mechanic to get the fluids changed and a general check over as I started to question what I had got myself into. I packed the GTR wheels into the car to get put on while it was there as I ran out of time which was a struggle because the handle to release the fuel door/boot was non-existent and just had the end of the cable tied to a bolt. It wasn't much of a surprise when I got a call saying that it looked like the fluids hadn't been done in quite some time. Although that didn't come as a shock, it did catch me off guard when I was told he couldn't open the boot which had the wheels in which I just had open not long before. Mission #1 was to squeeze through the back panel and open the boot from the latch while loaded with a set of wheels which to my amazement he pulled off after a bit of a struggle to reveal there was nothing holding the cable mechanism in place where it sits at the fuel cap. After that dilemma was solved the mechanic did an inspection over the car while on the hoist with nothing too interesting being found other than the expected crushed frame rails. It seems to have had some bilstein shocks installed at some point and judging by the AWD sump that has been sealed up I suspect the NEO is out of a stagea. By the time I got the car back and was ready to have my first drive home in it I was still excited but now quite anxious with the car already. First stop was to the servo to get a nice fresh tank of fuel as I had no idea how long it may have been sitting around for before I bought it. It sat quite nicely on the GTR stockies I must say. Now my drive home from work is short only being a 15-20 minute commute so the chances of anything going wrong is quite small right? WRONG. As I go over a speed bump only 100m from home I start to smell the dreaded smell of electrical burning and my lights drop out and shortly after the car dies. I am in extreme panic at this point thinking the car is going to burn down on its first drive before I have even had a chance to insure it. I move to the bonnet as quick as I can and lift it up, and as I go to grab the bonnet prop my brain is in such a frenzy that it takes me a second to realise my hand is being burnt to a crisp. This is where I notice that there is no plastic clip for the bonnet stay and when I have gone over the speed bump it has knocked the stay onto the positive terminal of the battery welding itself there. Levering it off with a nearby stick I sat there for a few minutes making sure nothing was going to burn down while waiting for a mate to come jump start me. My main stress was that I could've absolutely cooked the ECU or any other electrics. I was relieved when the car started fine with jumper leads on it but it would die as soon as the headlights were turned on so I carefully limped it home with no lights and decided it was a tomorrow task. You can see here where the stand sat on the positive terminal. Thankfully with a new battery the car behaved and seemed healthy. It was pretty smooth sailing for a little while getting to enjoy dailying the car. Interior wise it was pretty much as the seller described except for the the lack of working speakers, the digital controls had no power, and the headunit would randomly turn off & on. I installed a quick release I had laying around from an old car to help with getting in & out of the car and a nice momo wheel. I bought some oem side skirts to match the rear pods that were on the car already, who said a skyline can't be a practical parts mover. Test fit looks good! Found a good deal on a GTR wing & boot that I couldn't turn down. At this point the skyline was being too good to me and had to throw the spanner in the works again. First incident was as I was coming off the motorway and heard a bang and an awful grinding noise. As I pull over down a side street to investigate I notice my whole exhaust has basically fallen off and is dragging on the ground. After waiting around to let it cool to the touch I managed to get it back on its hangers. Thinking it was a weird 1-off instance I didn't think much of it until it happened to me again a few days later to which I see this time the middle hanger has snapped in half and the rear hangers have snapped at the welds. I manage to get the car in to a shop to get the hangers welded and while there I notice that my intercooler has broken its brackets and was being held up only by the piping. Quickly got that sorted and got some thicker brackets out of steel plate to support it all. Just when you thought at this point the car might give me a break, I fill the car up on my way home from the fabricators shop and after I pay I walk back to a good portion of my liquid gold on the floor. I just shrug it off at this point in exhaustion and call it a job for another day. The car had other plans for me though as the next morning on my commute to work, I am halfway there when I notice I am struggling to shift gears. I get lucky with a run of no red lights to work and find some time on my lunch break to investigate the problem. The slave wasn't leaking and the master still had fluid so I was left confused until I contorted myself under the dash and noticed the whole pedal moving loosely side to side when pushed in. Upon pulling it out of the car I found it to be multiple snapped spot welds on the clutch pedal bracket and the actual face of the pedal that sits against the firewall had snapped in half. I jerry rigged it with nuts & bolts at the spot welds but I will need to come back to this in the future and replace with one of the strengthened nismo brackets available. I then got to enjoy the car for another 2 months of cruising and dailying it, peep the obnoxious fireballs it would shoot every shift on the dodgy tune that was on there. On a sunday drive in that period of working car, I was on my way home on the motorway when I heard a slapping noise on my front left to which I pulled over to find my indicator had ejected itself from the car. Nothing a bit of tape can fix lol. I then bought some smoked indicators but after I realised I didn't like the look I found some damaged series 1 indicators. I repaired the tabs with some cut up cards and they looked good to me. My next venture was the hunt for some wheels, I test fit my mates Work Equip Spinning that were tiny 15" and I wasn't sold on the small wheel look. I ended up finding a killer deal on some Rays Volk Racing Group C in 17x8.5 & 17x9 that had been rebuilt many years ago and not ran on a car. I am still yet to get these on the car as they require some specific adapters and shank style lug nuts but I think they will look awesome. At this point my 2 months of reliability had ran out and on a cruise with some friends I suddenly lost the ability to shift gears again and thankfully could get it home by taking main roads and not having to stop. This time my master cylinder was bone dry and the culprit was the clutch slave that had decided to let go. It was a quick and fairly easy fix, but in my luck bad things always come in waves. Only a few weeks later I am on my way home from World Time Attack when the car completely shuts off while coasting down a hill, I try crank it while I still have momentum but no luck. Thinking I might have killed the fuel pump from running it low or maybe killed a CAS because the symptoms seemed to line up somewhat, I opt to get the car towed to a workshop to get fixed up on the Monday. When it gets there they get stuck into diagnosis and the CAS wasn't sending a signal to the ECU, and the fuel pump was also dead so it was comical for a small moment there. They replace the dead fuel pump when one of them notices some smoke coming from the passenger kick panel. Boy oh boy this is where it gets very bad and very expensive. I am not sure who wired the car when the NEO swap was done originally but I hope they never attempt auto electrical again as I am lucky that this handywork only managed to short and kill the ecu and engine loom and not do more damage. This is the point where you could say the 'build' started but not by choice. After some deliberation with my bank account I opted for a Haltech Elite 2500, RB terminated loom, and WB1. While I wish I stopped there and did the minimum of get the car running and leave it at that, I slipped into the rabbithole and decided I wanted to make the most of getting a retune and throw some bolt ons at it and see what it would do. I then threw together a bit of a mix n match build of marketplace deals starting with a GCG GTX3076R, a turbosmart FPR6, 980cc injectors, walbro 460, jackspanian ffp, throttle & fuel rail. At this point it was coming along nicely, the shop was making quick work of it and the bay was looking a lot nicer without the stock crossover intake. I also got them to replace the noisy centre bearing while it was off the road. Then we couldn't get an OEM CAS to talk to the haltech so ended up getting a PRP Street Trigger Kit for it.   While the car wasn't playing nice it decided to kill the stock alternator too so went with an LS1 alternator conversion kit. By now the car was pretty much done and ready to go but come tune day the car kept throwing the timing out every time it would warm up. Upon further investigation it seemed to be warping the PRP trigger bracket when the metal would get hot and expand which would cause the sensor to lose timing as it moves. Herman advised that they have seen the issue a few times now and don't know what the cause is. At this point I decided to switch to the PRP Pro kit with the crank trigger and considering the whole timing belt would have to come off I decided to get a new timing belt kit with water pump fitted. The car would now run fine with no issues and it was finally tune time. It ran up a healthy 275kw but ran out of boost due at 17psi to the rear housing being undersized. At this point the clutch also started slipping and due to it still being a weak RB20 box the tuner set it up to ramp from 8psi up to 17psi with the revs so that it wouldn't load up the clutch and box as hard. Car drives like a dream now. With the car back on the road I could return my focus to the smaller details, starting with getting a set of badges for the hood and quarters. I was struggling to drive with shoes on and I noticed that my accelerator pedal sits higher than my brake and clutch, if someone could confirm how it should sit that would be great. Next little changes was a killallwipers rear windscreen wiper delete, I also got some interior bits I was missing such as parcel shelf speaker covers, wiper trim cover, and boot floor and trims. Finally made it to a SAU NSW event which was awesome to cruise with a bunch of likeminded individuals. Another creature comfort I decided to look into was my lack of A/C. Since the Haltech got wired up the digital climate would power up now, and would blow but no cold air. First issue noticed was the lack of belt on the A/C compressor. After sorting that to no avail, it also had no A/C gas in it, but turns out the condenser has a huge leak. We are almost caught up on the story so far, but at the start of this month while coming into a driveway I heard a huge clunk in the front end to which I got out to witness whatever dodgy camber arms someone installed in this at some point decided to snap in half and I feel very lucky that it didn't happen at speed. Managed to get the car fixed the next day with some replacement GKtech arms. Next problem to address was the leaking gas tank from months ago. Checked the pump hanger seal first but that was fine, stuck my camera up after filling up to try scope out the leak which looked like the breather hose. Got the car up on a hoist prepared to drop the tank when I reached up to feel with my hand and I could feel that the hose clamp was missing and soon after felt that there was a gaping hole in the top of the hose. Replaced and tested and the car holds its liquid now and doesn't give me a fume headache whenever I drive it now. Finally have caught up and now onto fixing my latest issue which is the lack of dash light when driving at night, checked fuses first, then when searching I found the common problem of the headlight switch burning out but mine looks fine. Next test will be plugging a known working headlight switch into my car to tell if my switch is dead. Sorry for the long read but I wanted to be thorough, so if anyone made it this far I salute you soldier. Enjoy the rest of your day and I will keep this updated with issues I find/solve and any cool mods I can do inbetween. Merry Xmas!
    • can someone tell me what information a block number of 330680a on a rb25det engine specifies?
    • Would you suggest staying with a twin setup but upgraded turbos  ?
    • @Duncan hopefully they have a good hard look at Toyota. Both EVs AND performance vehicles!
