Choosing pistons
hopefully next month I'll be buying some pistons for my turbo build and Im after some advice as to what to go for.
I'll be using a sleeved block and to start with I'll be aiming for 400whp but i want the option to be able to go a lot higher (say 700-800whp) than in the future without having to open the bottom end up again.
So i was wondering if anyone had any recommendations for compression ratios, sizes and brands to go for?

im guessing your intending to sleeve as if not theres only 1 type of piston you can use.
personally id go for cp or wisescos. with a bit of a drop in compression but not to much. again im assuming with a power goal of 800hp your not going for any sort of driveability as it will be an all out drag car

Re: Choosing pistons
800 whp will probably never happen but it will only be if i take the engine with me into my next car which will be rwd. Basically i dont want to spend all this money and be stuck with something Im not happy with and have no scope for improvement.
So CR wise do you reckon 9.5:1 would work well?
