I see some people on here with high compression on E85. I was wondering how you like it and if you wish you would've done things differently (went even higher, or lower, saved the extra money it costed, etc). How was it to tune? Where did you get your pistons and how much were they? Did it seem to help your fuel mileage?

I want to go higher compression, I was thinking 10:1 maybe. I may just cheap out and go with 9:1 wisecos and a 1.8 head since the pistons I've seen cost so much more. I got a 99 GSX (purpley color) that needs an engine, so I'm thinking of building one and selling my white car.
