i have a 1990 b18a1 motor. i just recently bought sum itr pistons. i know you have to mod the piston or rod so they will not hit. but my question is will they hit the head. ive searched all over and can not find just a b18. all are about ls-v. please let me knowwww

 

no they will not hit u just have to shave the rods like 1mm on each side to fit the piston...i just did a b18b1 with usdm itr pistons...

 

its a non interference motor... unless you plan on not changing the timing belt. youre safe
