Difference in JDM GSR Engine and USDM Type R Motor?
Hey guys, I am getting ready to swap a 92 hatch with a Type R motor and had a question. I was wondering what the difference is between the JDM GSR Motor (B18c) and the USDM Type R Motor (B18C5)? I know the JDM has LSD and is very similar based on information that I have found, but I was wondering if you all knew any specifics of the engine such as compression, horsepower etc. Thanks for your help....

JDM GSR has a 10.6:1 compression ratio, and 180hp 126lb-ft.(??)
JDM GSR has the p72 head and cams and IM&TB, different pistons, rods, and crank.
USDM ITR motor has 10.6:1 compression 190hp (??)tq.
ported and polished PR3 head, different TB and larger bore TB
coated pistons, different rods, and crank.
Thats all I can think of right now.
