Just comp tested my motor yesterday and I am a little shocked at the numbers I have. 245-245-245-245 was what I came up with. On my original motor when I tested it with 30k miles on it I got 210-210-210-210 (01 B18c1). Why are these numbers on my new motor so much higher? I know the EDM/JDM motors will have a little more compression than USDM (10.4:1 vs. 10:1) but it shouldnt be that big of a difference should it? This is a B18C3 OBD-1 motor and stamp on the head says 96 I believe. Anyone have a reason why my numbers are so much higher than other GSR motors out there? Oh yeah, the motor has no internal or bolt on parts on it at all.
