any one ever put usdm b16a2 pistons in a b18c1 block?? on the compression calculator it says that its good and boosts the compression. with a b16 head and b18c1 block with b16 pistons it is 11.03:1. just wondering what everyones opinions are. thanks in advance

 

you preaty much looking at a poor man's type-r same block,head diferent pistons and cams but its a nice setup.. if anything i would use ctr pistons if your want a good all motor engine

 

yeah well im planning on going boost but dont have enough money till next year lol.. and i currently have a b16a2 engine so i was going to buy a gsr block to boost later and for now just swap pistons and run it.

 

throw some p30 pistons. the dome on these are a little higher than the pr3. little more higher compression.
