My F22C had 250,253,251,258 and settled down to 248, 240, 251, 245

Was that when it was brand new? What are numbers like when they are completely new?

OP - Science of Speed is one of the most reputable vendors/shops for S2000's in the market right now. I would trust data with their name on it.

Good luck with your purchase, sounds like a healthy motor!

This is interesting. My 06 ap2 s2k with about 120-130kish miles came out with 240-250 across the board. guess my engine is healthy.

Seriously? Its not like your body where you can get your cholesterol down by eating right and exercise. Engines don't heal. Wear is wear.

Compression is a test of how well the cylinders are sealed. Piston rings, valves. If there is wear, and these things don't seal properly, numbers will be low.

The only way to get numbers to go up is fix what is worn. New rings, valve job, etc. An engine rebuild, if engine still can be rebuilt (our engines are more difficult to rebuild than most, FRM cylinder liners, multiple possible bearing sizes, etc.)

If it's slightly down, there are oil additives that claim to help rings re-seal.
