Was wondering if there are any 86mm pistons for a b series that are under 12.5 compression. I got a b18c1 block from someone with sleeves and it needs to be bored to 86. I'm going to use it as a daily driver so in cali the highest octane is 91 at the pump. I was thinking of some k20 pistons but i heard the pockets and all that are aligned different but i wasn't too sure about that. Anyone know of any. All i see are 13:1+ compression ratios.

 

86mm is going to be a custom piston regardless of the compression ratio.

contact JE, Wiseco, CP or anyone else for that matter and they will make you what ever size with whatever compression ratio you want.

Might need to go custom then. I see arias has a 86mm one with 12.5 compression but thats with a b16 head. I'm using a gsr head so its going to be around 13.31. Going to have to save up thats for sure
