How much horsepower and how much boost can the stock pistons handle? I really want to get a set of manley pistons but i cant afford them at the moment. So im pretty much going to have to get stock pistons, but with how much money i have in the head i dont want to have a problem with them.

My 7g has been turbo for 4 years...and 90% of the time I have had it at 12lbs of boost. I did a compression test earlier this year and I had 210 all across the board.

Not sure on HP though since I never dyno'ed the car.

Just get brand new stock bore pistons. They go for like 100 bucks. With a good tune you should be able to push 12-15 lbs
