Just Bought An R33 Gts-T. Few Questions

[Blackkers]

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?

[wolverine]

Very roughly speaking 10-12psi + aftermarket engine management + 3" dump pipe + your existing mods = 200rwkw +/- 10kw

This is about as good as it gets with the stock turbo so think carefully about your next step.

[Blackkers]

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

[KiwiRS4T]

Either use the search function or Google which will often refer back to this forum. All of your questions have been answered at length many times.

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.

Correct sir

Mate thanks for all your help today

[jase_c]

also Greddy ultimate(piggy back setup) and nistune(chip added to stock ecu) for cheaper ecu management options

[wolverine]

Nistune won't work with a stock R33 ecu , given it requires a Z32 (or R32 ecu and separate VCT switching?) then this isn't the best way to go IMO given the other options.

[Dose Pipe Sutututu]

Heaps of standalone for $1200, or another option is to get an off the shelf one from Toshi (forum sponsor) as your mods are quite basic.
