Exhuast Housing Change

[r_speedfreak_r]

Hey all,

I got a gt35/40 with a .82a/r bolted onto my 30/25. I'm being told by everyone the turbo is whats stopping my car from making some decent power but i brushed off the comments keeping the engine response in mind. To my surprise ive noticed there are plenty of engines out there with bigger turbos or the same turbo with a bigger exhuast housing making more power than mine at 4,000rpm which is when my power curve jumps. Ideally i'd like to upgrade to a t04z but its an expensive upgrade as ive already got a t3 flange manifold. The alternative is to buy a bigger exhaust housing.

Does anyone know where the best place to get one is or have any opinion on what i'm looking to do?

Cheers for the input

Daniel

Daniel IMO the propper Garrett GT35 1.06 A/R turbine housing on a GT3582R is the end of the road for the "T3" exhaust manifold flange .

Gary used to say that a properly tuned twin cam RB30 would pull up at ~ 32-3300 revs if everything else was about right .

I've never driven or been in a TC RB30 powered car buy everyone that has says they are not lacking torque down low and you'd think especially if the CR was not too low or the cars gearing too short .

I think Brett at GCG in Sydney can supply those housings , give him a bell .
