Default stock compression w/ a turbo?

im starting to buy my parts for my ls swap into a fox body and after loking at my options for headers, i have considered doing manifolds with a turbo.

but my question is do i need to do anyhting to my motor?

it has stock pistons and i guess thats like 10:1? (its an 01 ls1) and i know any forced induction motor likes arounf 8.5:1.

u will still be able to have around 5-7psi with 60 lb. injectors and proper tune
10psi with race gas would be pushing it
u will need upgraded valvesprings and rod bolts for sure.

I believe the lq9/lq4 heads will drop the compression.
