Sum up R32GTR Build before tune - Parts ?

[reallyspeedly]

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)

You want fuel pressure sensor on that list.

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.

[Ben C34]

Yeah, the car costs way too much also.

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

You ask that question, but you know exactly who would use genuine.

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

Want my R33 GTR intercooler turbo to plenum hoses / piping ? It's like brand new but I'm still going to throw it in the bin 😊

Muricannnnnnsssssssss

bUt iTs hKs gOdZhiLllAAhh door stoppers that somehow look very similar to eBay turbos.

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!

Im located in europe, guess you are located a bit far away

Thanks!!

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

The skyline is located a few hours away from me.
Is there any fitting for the fuel pressure sensor on the fuel rail? Or do i have to make another solution for that?

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.

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’m 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.
