well i am going to rebuilding my b16 and im putting a CTR pistons in it and im not to sure if i am going to be needing OS pistons or not. i did a comp test the other say and i got between 190-200 acrossed the board.
i was just going to hone it out and put new pistons in.
car only has something like 50 - 70,000 km on it.
Do u think i will be alright with not OS pistons

 

Why not measure the engine cylinders and then see if it needs to be bored, but if your compression was good then you probably won't have to. But just be on the safe side and measure it and see if you need to bore it out.

 

well i could do that but i am driving my car right now and my engine is comming out next month for winter.
and i wanted to get all the stuff...
