Compression numbers - Honda Prelude Forum

So today i took my compression and i got 285 in all 4. I've got the jdm h22a. So i was wondering what could have been done to get those kind of numbers.

anything that raises compresion such as a milled head when it was possibly rebuilt, high comp pistons, milled block, and good rings.

Guy up there is right. Plus the JDM is crazy I have one.

K. So my buddy who took the compression saying boosting this one is now out of the option.

^He's correct. Boosting would be a very bad idea with those compression numbers.

Well that's good to know that there are some decent parts in this engine and that there has been a decent amount of work done to it. As you guessed i bought the care this way and the didn't mention anything about this stuff.
