New turbo setup! T3/T4, Pics added!

Hi everyone,
just wanted to share, I swapped out the restrictive stock turbo and built my own using the stock center section. Its a T3 hot side with a .63 A/R housing, and a T4 compressor side with a .50 a/r. It has a 3" inlet and 2" outlet. I haven't got the intercooler set up yet, but even with it necking down and blowing in the stock location, it is a different animal! Once it gets above 10 lbs of boost it really takes off! The whistle is unreal. I took some pictures, I just gotta load them up.

Jason,

That sounds fantastic! I've just placed my rebuilt (by me) stock turbo on my car, I too was thinking that a T3/T4 would be an interesting idea. Please attach some pictures so we can share in the excitement!

Cool! I was thinking about use a Cosworth .48 or .63 A/R exhaust housing with a small T4 compressor.

So a small cold side/large hot side combination works best on a diesel? I had it the other way around. My plan was to build a .60 compressor/.48 turbine using T3 parts. Is T3/T4 the way to go?

a VNT/VGT should be better, but the problem is the boost control (theoretically).

Well not really, the turbine side really needs to be a .48, a .36 like stock but not that restrictive stock one would also work. It spools ok, but not like it did. Then again, I still have more fuel to throw at it which should help it spool better. A .60 A/R compressor would work great, I just had access to a .50 T4 side so I used it.
