Just Bought An R33 Gts-T. Few Questions

Sorry for the new thread; I've done a lot of searching but didn't find answers to everything.

I just bought a series 1 R33 with RB25det and a few mods.

3 inch turbo back

big FMIC

aftermarket coilpacks (not sure which brand)

heavy duty clutch.

boost gauge in cabin.

Stock turbo, motor, injectors, ECU, fuel pump

It maxes out around .6 bar maybe slightly more. Is this just wastegate pressure? I know its an internal wastegate I have no experience with internal gated turbos.

Power ramps up quickly between 3-6k RPM, but backs off between 6-7k. Never experienced this with a turbocharged car before.

I know I have the mods to support a higher power set up, it feels kinda slow compared to my old Honda Prelude turbo.

My question is, how much boost can I run on the stock fuel pump, injectors without pushing ~90% duty cycle?

Also, how does the stock fuel mapping go with 12-14psi?

I thought when people say Turbo back that included the dump. I'll have to get under the hood and have a proper look, haven't had time yet.


What are the preferred value options for aftermarket engine management? My old tuner is Adrian at Toda in Sydney, I should give him a ring

Sorry my bad, I misread turbo back for cat back.

There are a bunch of ecu's available from the older powerfc's to Link, ViPec, Haltech and Adaptronic. It will come down to what your tuner likes using.

There are a few very good tuners with extensive experience with RB's that are mentioned regularly here at SAU. It might also pay to do more reading on who people like using.

DVSJEZ and Unigroup are two tuners I have no hesitation suggesting but there are plenty more in Sydney or thereabouts.

Mate thanks for all your help today

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
