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 .

Cheers A .

    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
