I have a 90 formula, i was planning on swapping a ls1 into but i failed to think bout forced induction with the tpi setup so i am going to give it a shot.

So far my bottum end is going to be fourbolt main, cast crank, forged rods, forged pistons dish, roughly a 8:4.1 cr, heads will be 190 64, intake either modded stock or tpis miniram, with that low of cr what kinda psi could i run i was think ing like 20? 25? i no about turbos and how to work with them, just not alot about engine setups and all that jazz so i am tryin to get an idea of what all i need to take into consideration. Thanks, Evan
