I have a H22A (of some kind, if you've seen my other thread-haha), and the compression is 260 all the way across. There all the same, so I would suspect that the compression is this high for a reason.

What compression pistons would make my compression this high? Or could it have Type-S pistons? What does a normal Type-S H22 generally have as far as compression numbers?

Would the Type-S motor have anything different then the normal H22A's as far as cosmetics or anything?

 

normally the numbers aren't absolute. could be faulty equipment/other factors

as long as you get a consistant reading, thats what matters

not like 190 250 230 200.

 

yes type s pistons are a bigfactor for hp gains on the h22's compare to USDM and JDM motor heard the Type S are more reliable and HP friendly =]

next time try to learn proper english skills.

HP friendly? pretty general term seeing as if one was running different setups (turbo or NA), type s pistons might be a negative eh?
