Question Piston Upgrade Path

I come to the conclusion that I want to lower the compression ratio from 10:1 to 8.5:1 on MY01 GC8. The first option was to go through JE, but there piston are for EJ25D and my con rods would have to be modified and the pistons would be custom($155 a piece) bring the total cost to $900+ w/install. Does anyone know of any other option(s)?

I'm doing this because I going turbo, and I need a reliable daily driver. This seems one of the best ways to make this happen along with new Cams and Valves, but those are easier to find.


It looks like the JE pistons will fit on my car after all. You'd think a vendor would know the difference between the year models, he thought I had a WRX. Now does anyone know where I can buy these? I tried google, but I couldn't find anyone. I probably should have realized by the engine code. DOH!

Cobb Tuning, B-Spec, ISR, JUN, and a couple of others. I got mine from B-Spec. They had to be custom made to fit my cylinders. I had to have my block honed out. Good idea getting it done. It could save you alot of money later on. Good luck

i was about to respond asking why the hell the JEs wont fit but i see you found the asnwer that they do.

i recently bought JE pistons. who did i call? um...JE of course i ordered it directly from them and got 9:1 and 100mm (not the size and compression they currently use so it cost me more) was about 600 shipped.
