My opinion is this should be one fast GTA.

Everything sounds good to me. The HSR is a great intake from what I've read about it over on thirdgen. I think personally that any of those 3 intakes should really haul the mail.

I understand your rationale for building a car you really like. The GTA is a unique vehicle and certainly worthy of holding onto and building up as you envision.

With 11:1 compression I would definetly be looking to aluminum heads. Weight savings and the fact they handle heat and compression better, is nice too.

With the good flowing heads, I would look into getting the intake that flowed the most cfm, period. Since the heads will be able to move a lot of air, you might as well be putting as much as you can in the combustion chamber.

Just my 2 cents.

You may want to go with a different set of heads. Back when I still visited thirdgen.org I heard about numerous problems with trick flow, like bad valve guides, oil burning, ect.

The best set of heads out there are AFR's. I bought a set with my last GTA and though I didnt get to drive it for very long I was very happy with the product.

yes.. AFRs are very nice heads... I was just talking to a friend that owns a race Engine shop about them yesterday and he said that in his opinion i could get a canfield head that would be just as good... but i have a while before i hafta purchase a set of heads so maybe i can run across a set of used ones for a decent price
