I think there is no absolut thruth using pistons but I think that I try to use stock pistons ...or not... I have to think about it... ;\) But this information is very helpful, thanks guys!

But how about turbo? Can you recommend some specific turbo, if I´m trying to stay below 10 psi and seeking as much power and torgue as possible at low rpm? And I´m going to use carburetor, so please give me some advise what kind of blow thru carburetor you can recommend. Yes, yes I know... EFI is much more better, but still...
