My friend is going to do a LS Turbo upgrade, my question is what are some
essential things he should do before this? how should he build the engine to prep it?

 

how much does he want to spend
how much power does he want to make
did he do a compression/leakdown test on his engine?
how many miles are on his car?

many, many questions...

what he should do is sign up on this or another forum, do a lot of research, find out what other people did/didnt do/wish they did/wish they didnt do...

 

hey thanks man, I will ask him some more q's which I should have done b4 posting, but price I think is $4000 area? but yeah Ill tell him to sign up to this site...thanks again
