I have a B18b or B18A1 IDK remeber and some USDM ITR pistons. The pistons say P73a on them. Im trying to get the pistons NDI'ed becuaser I bought them off of ebay and dont or cant tell if they are any good.

MY QUESTION IS : are these pistons going to fit in this block because I read some were that the oil squiters are different or something? If I cant throw these in the block what would be a good combo?

This is my first build. I want to build up a all motor beast non VTEC. My inspiration BisiMoto. If you know what I mean .

 

or would they be compatible with a LS crank??

 

for one b18 ls motors dont have oil squiters and two yes you can put itr pistons is a b18 ls block
