660cc injectors

Weldina NE-1 Exhaust

Hi all just got my R33 GT-R le mans tuned.

Unopened r33 rb26 done just under 100,000 (whether it is legit or not lol)

Mods:

r34 n1 turbos

Ported stock manifolds

Split dump pipes

Xforce front pipes

100cel cat 3"

3.5" cat back

Apexi pods

Trust fmic

Hks evc-5

Link g4+ ecu (no afm's)

Siemens 660cc injectors

Nismo fuel reg

Walbro 255

OS Giken twin plat clutch

Probably more i missed.

Made 300hp on 14psi

365hp on 20psi

Was hoping for abit more after seeing some of the results here, but tuner said to do cams/gears/springs and should get near the 400hp mark.

You should only need cam gears, the cams and springs are more then fine to support over 300kw(400hp)

Might want to get rid of the split dumps and maybe check the fuel is good (i.e. The servo put the correct stuff in their pump)

Thanks for your input,

will probably change cam gears next time i service it, dumps i probably should have changed when the turbos got replaced last week lol :(

and the fuel has been sitting in the tank for around 4 weeks so shouldn't be foul and i used caltex 98, but yeah possibilty of shit fuel maybe.

Depends what split dumps they are, I have split dumps on both my cars, 32 on stock turbs makes 291rwkw at 19psi and the 34 with GT-RSs on a 3.0 made 435awkw on 24psi

Does this seem low/laggy?

34R

Haltech Platinum Pro

N1 manifolds

-9s

HPI dumps and 3" front pipes

Full 3.5" exhaust after merge, catless

Stock airbox with apexi panel

E85 with 1000cc Injextors and 460lph walbro

22psi despite what graph says.

Cam gears, intake 3deg advance, exhaust 3deg retard.

Twin turbo pipe mod

Torque is oddly high also.

Rpm jumo was explained as tacho pickup on the injector wire because he can't get to the coils

I have a second graph that's fine.

You would need to find out exactly what the revs are for us to know but going off the speed it looks like it was dynoed in 3rd or maybe 4th

My 4th goes 205@7000 but then it is a little bit longer the factory

Dropping off at 160kph seems like 3rd if it was revving around or over 7000 rpm?

4th apparently

I just liked to drive them and when they do not do what I want, i changed it until I was happy. So I guess it is up to you, if you feel the car runs great, it is great :)

Going off the Dyno I think yours looks really good and should drive great on the road and track. "Can only guess about the track, lol"

How do you like it ?

Post the 2nd graph

Twin GTX2860R 0.72 rear housings

Precision 46mm ext gates

Custom stainless steam pipe equal length high mount manifolds

Tomei oversize oil pump

ID 1000's

Twin Walbro 255's

2.5″ stainless dumps, 3" dump back

CNC Steel adjustable cam gears

Twin 6″ K&N pods

PWR Aero2 cooler with 3″ outlets

PWR twin pass X-flow 55mm radiator

PWR 21 row oil cooler

SPAL 16″ skew blade 2000CFM thermo fan

3 Quart Accusump

Custom RWD R33 GTR sump

CNC Steel adjustable cam gears

Stock cams

Stock bottom end

Stock head

373.2kw @17psi on E85

Compression test prior to the dyno came up with 185-190 across all 6, not sure why it was so high. Tried wounding out some power but caused misfires, so wouldn't make any less.

New cams, ECU and valves coming in the next few months, no idea what it will make when retune happens.

    • LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.
    • I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy  
    • If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.
    • Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.
    • Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
