Didn't that car go like 10.80s easily or something? How fast do you wanna go?

Its been 10.66 with out the new 67/65 billet turbo, but i want to go as fast as i can

Ported TAs or some Champion ported GN1s are your only choice if buying new. . I think Nick Micale is selling some ported TAs that are fresh.

You need to feed it a lot of fuel if you want to come close to using up that turbo even with the heads you have on a different short block. You should be able to go 10 teens with what you have.

I upgraded the fuel system, it has a nice weldon external pump on it now, so fuel isnt a problem. I sent nick a pm on the heads already. I was just wondering how much of a gain i would get over my ported irons, and which head would be the best for my combo
