(pr3/p30) B16A pistons will fit the crank b18c6 + b18c4 block engine??

greetings from Poland

 

Pistons don't fit onto "a crankshaft", they fit onto the connecting rods.

With a little machining of the small rod end width, or the piston pin inside width they will fit onto the B18C rods.

An easier option would be to use ITR pistons as they are a direct fit and almost the same compression height/dome size

BTW: wrong forum..

 

I now have the b18c6 pistons, but the engine takes the oil. I am making a repair block. I want to buy p30 pistons.
what others buy?
