Nik, wow buddy, great find there. That's only a couple hours from here, I could drive down there to get stuff.

Irishflame27, you are on the right track. Just remember to use good engine management and tune carefully. The GZE pistons are great, thought that deal from IPP is worth it. You should be able to run 12 psi or so, I would be careful running more than that. Before you up the boost past 12, do your other stuff first like porting the head (or swapping a GE head on) and so forth.

that is a weak kit..

remember the weak point of the 7afe engine is the conecting rod..

even with that kit you cant push past 12 psi ( i know it lowers compression allowing you to boost more ect ect.. but it doesnt fix the weak connection rod problem)

what does the freeze plug do?

How is that kit weak? I don't get it??

I sent Roy from PSI RACING a e-mail asking him what he did internally on his 7afte he ran 14.4 on 15 psi http://www.mr2supercharger.com/7Aengines.html the artical is in the middle of the page.
