I think the second one had worn piston ring or it has too much gap between the
cylinder and piston ring... the compression was no good....
Don't worry man...I know what to buy I know the compression...
I always check the compression before i buy motors~~~


both of those motors are TRASH. stock spec is 156psi with a minimum of 128psi for the SR20DET. apparently the only thing you know how to buy is junk motors.
