I just did the compression on a friends mr2 turbo and it was 120 across...is that right? Seems a little low but I don't know much about mr2's....if anyone can help let me know...thanks....

 

thats not right at all....even single cam small HP honda motors should have more than that across the board.

 

correction.. it doesnt matter what the compression number is.. as long as its all the same across the board.. it doesnt matter if its a single came.. dohc.. v6.. v8..

turbo 98.. did you do it when the car was warmed up or cold.. that makes a difference.. but last time i checked.. it shouldnt matter as long as the numbers are all the same across the board..

 

We let it run for 5 minutes before we started....

 

it should be fine then.. as long as the numbers in each cylinders are all the same.. i thought my compression was a little low.. with the fully built gsr.. cause it was 140 across the boards.. and i was used to my b16 being 220.. but a reliable source told me.. that as long as its the same all the way across.. its good
