Rb25 Turbo Set Ups

[ti2l]

Hey guys

have googled my my space and searched out the wazu and cant find any info that satisfies.

Story goes along these lines.

Car:32with stock rb25... standard cams, fuel reg, Adaptronic ECU, front mount, 3.5 inch exhaust, profec b controller. rev limiter set 7k.

Use: drift and occasional daily duties.

Desired outcome & power: 240-280rwkw would be nice but also chasing response and not choking top end power. 18psi or so by 3200-3500

I am leaning towards the 3071 or the 3076 from the information i have come across and budget wont allow HKS.

I am uncertain on the rear housing size i am going to use as i am finding so much info from people with only opinion and "educated" knowledge on a similar set up. Really i would love some info and dyno sheets from people with the same or very similar Internal gated set ups (street legalities for the moment) and tuners who are familar with the same thing.

Given NSW state of drift at the moment i am placing an emphasis on response given the tracks like Marulan and the occasional trip up to raliegh raceway. Big track at Eastern Creek and wakefield days also happen so not wanting to choke power at high rpm too. Leaning on internal gate as car is attempting to be street legal to an extent (engineered as 2 seater for cage etc etc already)

I can get hold of a 3071 with .63? rear from a friends Sr for a good price but from my understanding this will be pretty much useless to me power wise after around 5000rpm or so.

any info would be greatly appreciated,

cheers

.82 3076 IW 250rwkw @ 17psi, all in by 3700-3800 in 3rd and up

did you even see the dyno results thread at the top of this forum?

3071 with .63 rear, 22psi on e85 should give you just under 300 and full boost by 3k.

Clearly he did not

OP - Please read the dyno sticky thread, or simply search the turbo ID.

There is that much info in these pages on 3071/3076's that will keep you reading for a month if you want.
