I got a b16, 81mm cylinders. Just wanna know that if I buy 81mm ctr high compression pistons, will it fit my b16? Imma put the ctr pistons on my jdm
b16 rods and will it be okay if I put it into my jdm b16 block?

i have heard the CTR's are VERY tight in a stock B16 bore ONLY heard never done so not 100% sure u might need a hone to get to proper ring end gap and piston to bore clearance just mic ur pistons and snap gauge/ mic ur bores, Bore taper then call honda for your factory service limits on piston-to-wall clearances, and bore taper

They are a very tight clearance. I would run them for the simple fact they have such an extreme dome, that often you don't get a complete burn during combustion because the bottoms of the dome are so far away from the spark.

In general, the flatter the piston, the better the burn. If you want higher compression, find some P30 pistons imo

Thanks for the help!
