yeah for sure man, if its a D16A6 like mine then it has a 9.1:1 compression ratio, but i'd still get a thicker head gasket, thats what i'm doing, they are cheep.

Its a very good engine to turbo, cuz its cheep if youscrew someting up.
but i dont think you need rods and pistons, unless you want to run over 10psi on it.

I wouldnt even worry about replacing the head gasket either. The D16/D15's have very turbo friendly comrpession. The only advantage switching to a new headgasket would be to run a metal (triple layer gasket) like the d16z6 gasket. The a6 has a composite gasket.

I have had 2 turbo mini-me's... Both were pretty good, But I did end up blowing the head gasket on one of them.. a bit to much boost.
