:P jokes jokes

welcome to this here sau, also check out www.sauqld.com :yes:

yo..

please educate my friend.. im trying to convince him/her that a 1jz engine is a far better choice than a RB25 neo/RB26DETT..

for say a 180/silvia or a project car..

stock for stock or modified.. im done trying to convince him...

I was almost convinced this was the case too Marki but since i have started sniffing around motor sport circles I have heard of plenty of the 1 and 2j donks that have shit themselves. Apparently another phurphy is the story about the forged bottom end. According to one 2j owner I spoke to its nearly all bs. Forged pistons yes but thats about it. and lets face it, pistons dont make a bottom end.

Given the amount of parts and info on the rb I wouldnt hesitate to mod one again and if this one doesnt go the distance (which I am sure it will) I will find out why not and rectify it.

yep.

but u tend to see that the general JZ engine has far supirior oil dispurtion and coolant circulation.. make that bit more power standard block..thats standard to standard.

but i knw what ur talking about with just istons being forgies...

with the SR20.. u cna have a full forged engine but in the end u still got a weak alloy block and they dnt see more than 700ponies :rolleyes:

It's hard to convince him because it's not just about 'the engine'. Reliability is important of course but you aren't taking into acount ease of installation, availability of parts etc. And don't just write of RB's like that either. Yeah sure the JZ is a well designed engine but 90% of RB engine failures are tune related. Too many tuners who do a half arsed job. It'll bring the strongest engine to it's knees.

At the end of the day, like Dan said, it's not the debate of which engine is strongest in stock form, it's pretty well documented that the JZ is probably trumps in that department. But the effort involved is rediculous when looking at the comparison of swapping either engine. The conversion is no longer unique, its been done a few times before and for the extra cost involved you could have a tougher RB.

ok

im diagnosing why im getting nothing much from the RB20..

its got a Z32 AFM with standard ecu..?

does that work.. from my understanding the Z32 has a different voltage correct..?

with it cranking over im not getting the injectors to open and close (electronically)?? using a test light and checked i off Inj #1 while cranking. i have fuel flow, ignition (diagnose by playing with the ignitor) enough to splutter but not keep on going..

cas seems good. so im shooting for fuel..???

anyone..

The other thing you could try is to remove the return line from the reg and turn on the ignition. If there is not enough pressure to bypass the reg, then you will never start it.

Then check spark. I can test your coil packs, PTU and injectors with an ignition tester I have but you should make sure you are getting power to everything first. Chuck a noid light on the injectors and see if they pulse. The Z32 AFM won't work on the standard ECU as it has a different resolution, but I'm not 100% on whether it will stop it from running completely. If you get stuck......I'll happily buy the car from you for $1

    • Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.
    • I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it
    • If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣
    • I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.
    • Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.
