Just went to Pep Boys and bought there $25 compression test kit.......here are the results...........

cylinder #1=261psi
cylinder #2=260
cylinder #3=261
cylidner #4=262

Is this conclusive evidence that my pistons and rings are fine? Can I compute my cr with these numbers? Are all compression testers basically the same, or would a more expensive compression tester yiels different results?

 

Those numbers look real good. Your pistons and rings are probably fine. You can't use those numbers to compute your compresion ratio. A cheap tester is fine. Your just looking for all the readings from one cylinder to another to be within 10% of each other. (And not be too low of course.)

 

 

on the c-speed site their 11:6:1 itr was putting out 250 across the board, mine being 10cc higher, would it be fair to say I am in the 11:8:1-11:9:1? ANd the stock 9:5:1 B18B was putting out 175 across the board

Those are really good numbers
