Celica Forums General Discussion Exterior internals

i just bought a t3-t4 turbo from turbo-performance.com and now i want to go ahead and do the internals...pistons/connecting rods/rings. ect...dont know how big to get the pistons to get the best compression for the turbo factory is 3.11 this is really not my field so looking for suggestions. thanks

wait a minute, you bought just the turbo and expect that thing to work by itself? or did you purchase the KIT?

no i got the blitz super sound blow off valve...turbonetics wastegate. injectors, intercooler. ect.. got it all. but when it comes to what bore size and internals i am lost? : )
