I was curious to see what my compression was on my engine, so I had a shop test it for me. My results were 200,210,200,185. The guy told me that was not bad and not to worry that cylinder 4 was off compared to the others. The engine was a jdm import so it maybe had up to 45k on it when i got it installed. Since then I have put almost 10k on her. My concern is would it be reasonable to continue to upgrade and perfomance mods with these type of compression results. Or would I be wasting money. Eventually my upgrades would be complete stage 2 valvetrain, 2.5 exhaust upgrade, port & polish, and resleeving block for 88-89 bore for 12-12.5 compression.

 

185 is a little low, but nothing to worry about. other cylinders are all good. mod away.

 

Also if you are re-sleeving and throwing in new pistons that would correct the compression....... provided there isn't something crazy going on in your engine.

somebody correct me if I am wrong..

 

i kinda thought that if i resleeved if that would make my compression rise again. i figured that cylinder 4 has some stress in on it or something.
