Are GN1's worth upgrading over ported irons?

As in the sig.

I'm talking for the $$$$$.

Or would a bigger turbo be the way to go since it's about the same $$$$ when it's all said and done?

Like I got any $$$$ right now

GN1s vs irons

Are the iron heads you are talking about Champions? How fast are you looking to go? What turbo do you have now?

I'd say work on the 60' for the "cheapest" bang for the buck

with your power, low 1.5's should be easy

GN1's certainly flow better than irons, but how soon do you really wanna blow things up?

You are right about the 60ft

Hopefully don't blow up too soon!

Should be getting my converter back soon that should help with the 60ft, that and more tire

Stay with a Set of good Ported Iron Heads...

Good Ported Irons rock into the 9's.

Take it from a guy who's had champion irons and GN1's. STAY WITH THE IRONS!!! These aluminum GN1's are nothing but trouble. Not saying that they can't be good heads, but if you buy them, make sure someone competent checks them out for you. The guides on mine are bad out of the box, and they were built late sept. 2003. They were supposedly "checked out", but apparently not very well. Now I get the joy of yanking my pos heads off my brand new motor and paying to have them fixed. I never had a problem with my irons, sure do miss them.....

Guess I'll stick with the irons, on the GN

Guess there worth it if you have a "high end" build up?

Thanks.
