First of all. Thanks to everyone in this forum helping me out with my wierd questions back and forth.

So before i install everything on my GTR and send it away for a tune i will sum up the parts that ive now bought/on its way and let me know if there is anything else you would recommend me doing that could be important.

Engine:

Garrett GT28-5 x 2

JE-pistons 8.2:1

Eagle H-Beam rods

ACL race main and rod bearings

Oil pump collar installed

Fuel:
Bosch 980cc injectors

Walbro 535/E85 pump (no check valve) I guess i can buy a check valve and connect it to the pump?
 

Other:
AEM X-Serie lambda

New Air tempsensor
Older verision of LINK G4 ECU

(upcoming: Gonna remove old fuel hoses for new ones, change oil pressure sensor, attach oil accumulator, )

I guess a new clutch is what i need aswell. Advices? Been running Competition clutch before on other car. But would rather spend less money on this one.

 

Something else in these cars that i need to upgrade when im gonna run -5s? (Low power as possible with -5s)

Oil cooler?

Head refresh?

Replace every coolant hose.

The coolant hose/vacuum hose line item is easily north of 500 USD these days if you really do replace every last hose and pipe that has questionable integrity.

But who in there right mind would use genuine ? Good silicone hoses are cheaper and last a lot longer than the factory rubbish.

Who in their right mind would buy journal bearing turbos just because they had HKS logos on them?

I have a oil cooler, could install that one.

Fuel pressure sensor, good one. Forgot aobut that!

Head refresh? The engine block/head has been in for service. So the head should be fine!

Well, idk if that matters after all these parts i had to buy to get that car running. Would probably be better to sell -5s ( with a bit loss ) and go smaller turbos and less power hihi

Depends on how you want to do it, you could either keep a running tally of the things you need to replace as you dig through it or just replace everything wholesale. I ended up doing the latter when I pulled apart my intake manifold and oil cooler/oil filter housing down to the hose clamps which were all replaced with factory constant tension spring clamps. I spent probably 100 USD alone on those stupid spring clamps.

Is there any fitting for the fuel pressure sensor on the fuel rail? Or do i have to make another solution for that?

Expand  

There is no factory provision for a fuel pressure sensor, you could put one after the fuel filter but before the rail though. That is a common spot for flex fuel sensors. I'm pretty sure that's the point that you're supposed to use when following factory service manual procedures for testing fuel pressure anyways.

Yeah nah. Flex fuel sensor should be put in the low pressure return line. No need to punish it with several bar of static P.

P sensor in the rail feed line is sensible. But the obvious answer here is to buy an adapter to put an aftermarket pressure reg on the tail of the fuel rail and use the gauge port on the reg to mount teh P sensor.

Either way that strut tower is an easy place to put it, both feed and return run under the plenum.

Hmm okey.  But what's your reason to use pressure sensor? I've only used a pressure gauge on the line/with aftermarket regulator on my other cars before. Are your reason to use a sensor to be able to connect it to the ecu, or to be able to have a gauge in the flightdeck/cockpit?

I guess i could get an "T" adapter with a 1/8" fitting for pressure sensor placement. And connect the fuel hose on the other two ends and place it between fuel filter and rail?


If i go for a regulator instead, i could just remove the "oem" regulator and put the new regulator on the strut tower on the feed line between filter and rail. I guess i could just use the gauge on that regulator? Wouldnt need the sensor for pressure reading then?

I would run a fuel pressure sensor if I鈥檓 already doing the work to set up a flex fuel sensor because it provides a clearer signal of fuel pump failure.

And more importantly, you wire it to the ecu and use it for protection and logging.

It's 2023. Mechanical fuel pressure gauges are basically obsolete.

Right, that was what I was trying to say but didn't quite make explicit. RBs are expensive to blow up for dumb reasons.

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.

      Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:

      Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
