upgrading stock 1987 turbo?
 

Hey guys, I am in the process of purchasing an 87 TII, but it needs to have the turbo rebuilt. I was told i can somehow get a 60-1 compressor in the stock turbo without having to modify the center section. Has anyone done this? What kind of power ranges, spool times would this produce?

ttt

anyone know anything about this? or at least somewhere i can read about it?

this might help
