Choosing pistons

No, not in the key of C. An H is likely involved though ...

Choosing pistons

Post by FrontBackSide2Side » Mon Feb 25, 2013 9:01 pm

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?

the lower the cr the higher the boost but also the lower the cr the worse it will be off boost

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

800whp

Is that even plausible in FWD?

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?

^ pretty sure there are several about running ~400hp even on their 89 gasoline.
