Today since I have not done a compression test in a while (9 months), I decided to go ahead and do it again. The stock D16Y8 compression should be ~184 per cyl according to Helms. Mine today measured like this (4-3-2-1) 184-180-186-185. Needless to say I am very happy with these results, I did each cylinder twice and every time they read the exact same give or take 1psi. I went turbo April last year, and remarkably have not had my Hondata tuned! I know, a big on me. Money has been an issue of late and I have not been able to afford to have it tuned, but tuning is the next thing that will be done to the car when I get the money saved for it!
