Im going to buy a JDM GSR engine this weekend for my civic. My old one blew up just curious what should the cylinders read when I get them to do a compression test for me. Ive read that theres sometime 10-15 psi difference which isnt a big deal. I just dont want to get screwed any feedback would be much appreciated.

 

i think 175 and up but around 200's is very healthy, and its more about consistency throughout the 4 cylinders, i heard 10% and 15%
