what is a good compression rate or an average rate. iim new to compression i wanna find out more about it .. i wanna do a turbo setup on my 90 teg.. and i hear alot about having good compression....thanx for any help.

 

i think like high 180's -210, anywere around there is good, the higher the bertter, and what matters most is that the compression of each cylnder is close of the same as the others.

 

What motor do you have???

LS is 195 max. GSR is 210 max

i thought 240 was the max and not 210 on a b series motor? can some one verify this?

only thing i can verify is that my LS had 150 compression across all four when i tested it amost 2 years and 33k ago. runs perfect.

 

its a stock ls

 

i believe 195 is max for a LS motor.. but the main thing to look for is the numbers are not TOOO low.. or There isnt TOO much variation between the cylinders.

good stuff

 

i pulled 200-205 psi each cyl, on my 93 ls. i dont know if the tester i used was accurate, but the important thing was they were all even.
