I think you should get new turbo, maybe those greys and a proper mapping for them.

 

I run a T34 (modded, but dont ask how) and im on 25 psi at 440 ish bhp, as has been said, get some greys (although mine are on the limit apparently) and some good mapping and you wont be far off, just dont push it into the realms of being totally unreliable, i'd rather have 400 bhp and know its sound than push for that little extra

 

I have standard T34(or T35 like we call it in Finland) with standard .63 exhaust and I dynoed last summer 350bhp with about 22psi and the exhaust backpressure becomes a problem since the exhaust (wheel, etc) of that turbo is so restrictive. The car was dynoed on dynodynamics rollers. Here is also link to the dyno paper http://www.saunalahti.fi/~jatuomo/Es...a/IMG_2241.JPG
