As some of you may know I am working on my 7afte. My question is I found these three auctions on ebay what is the difference between these 7afe pistons? What does the .020"/ .030" and .040" stand for? If I get the one with the biggest bore will lower my compression a little? Stock bore is like 81 I think the biggest one below is 82 is that enough to get a little more air and fuel into my cylinders? Does it even matter? I am getting a set im just curious.

My guess would you would prolly be able to take a bit LESS boost. Bigger displacement would mean you are getting more air and fuel burning with the same stock piston rods which is the big weakness with the 7a. So unless you were to get new rods You'd prolly be able to safely boost the same, if not less. But i doubt any more.
Compression should stay the same too. -Ryan -------------------- AIM : FAQdaWorld
