So you want low compression gsr pistons? I wouldn't go cheap or espcially used. Check out the site sponsors.

I'd go with a 9.6:1 forged piston. Going too low is unnecessary and the car will lag ass out of boost. Ever driven a 8.8:1 B20 with a medium or large sized turbo out of boost? It's a dog. You won't find a cheap set of pistons that will work well for very long. I'd save the money and get a new set of Weisco, JE, CP, etc. You don't want to spend a lot of money on your turbo and tune just to have the bottom end fail, ya know? Just my $0.02

Good luck :thumbs up

BTW just out of curiosity what turbo are you running and what are you tuning with?

82mm is the max on stock sleeves, but you CANNOT exceed this. I would stay at the STOCK 81mm bore. This will provide the most structural integrity for the cylinder walls.

If you bore to 82mm, you wont have any room to fix any wear in the cylinders if you take it apart and have to re-bore it. You would need to replace the block in that case.
