Hi all, just looking for a bit of advice.

I have stage 2 cams installed now with springs and retainers. The compression on a B18c is quite low for NA to gain power with cams I believe. What high compression pistons would I need to suit the stage 2 cams which would be safe for clearance?

I'd imagine somewhere between 11.8:1 to 12.5:1 if I remember right. You can contact Skunk2 directly to ask what they think is optimal. Stock b18c comp ratio is 11.1:1 is I remember correctly
