"upgdrading" To A Smaller Turbo?

[Aiight]

32psi is well beyond safe for 98octance fuel.

getting it on a dyno would be a very good idea.

It has flat torque from 1300 to 5000 (2700)

but the rb26 can have flat torque from 3800 to 8000 (4200) can't it?

just launch at 3800 and you have the bmw 335i bi-turbo,

except with 150hp extra at the crank.

i'm thinking 32psi is well beyond the safe limit for those turbos too.

after all, they are made by mitsubishi, which is the exact same place mine are from.. and mine would be pushing shit up hill go above 18psi, let alone 30+

32psi (16+16)?? i dont know. i'm not a beamer fan. that's what he told me. i assume he'd know.

i'll try get some definate specs from him.

has he lost some mouldings and the back of his side mirror?????? (driver side)

you already have a good tuner (trent). ask him what he thinks. but honestly it's not a realistic goal. the best you can do is go to a 2530 or GTRS, to get you to the 250kw you want, but you will loose some response. if budget is not such an issue then the way to do it is:

RB30 bottom end

RB26 head with ITB set-up etc.

ported head but squish zones left well alone

ported exhaust mani

GT-SS turbos

mild cams or even better, V-cam. (these really do help spool up)

good EBC

more than 9:1 comp ratio

this would be super responsive. I'd say you could hit 18psi under 3,000rpm.

minus the EBC (which i've got a Blitz Spec-R) what $$ would i be looking at roughly for those parts plus a guess at labour?

much of a price difference between the 2530 and RS?

hahaha, yeah, i could just drop in a BM TT6

he was having the window mouldings painted black at the time. and the mirror housing was broken in some road rage incident. lol.
