i was looking a a t28 turbo, maybe a t3/t4. im looking to run about 15 psi or so. i know i am looking for pushing 200 hp and up for sure. i just want to make sure i do the right things to my motor before i put a turbo in it. looking at a 9:1 rate. and hmm.. i dont know about the bore and sleeving.. any suggestions?
