RE: OS .21 VZB V-Spec compression?
Yes, i agree. First time i was trying to start that engine, it was MEGA HARD to rotate it with your fingers below of the chassis (if i take the engine of the car and trying to turn it with my whole hand, the compression was not so hard). Now, that my engine did a few gallons and after replaced piston, sleeve and con rod and performed the break-in procedure again, is just fine, easy to turn the engine
