whats the difference between the usdm and the jdm b18c1, sorry kinda new to honda

 

well, for one, b18c1=usdm and b18c=jdm
please search though!

 

Welcome to h-t, before any more search patrol comes I will help you out since you are from houston and it is your first post. Okay there is technically two JDM B18C engines. The one you are talking about is the 180 hp JDM SiRg motor. It is essentially the same thing as the USDM GSR B18C1. The other B18C is or course the almighty JDM Integra Type-R engine making 200 hp at the crank. I believe the only difference between the JDM 'GSR' motor and the usdm version is different cams. I am not sure what else but thats what it is if i remember properly.

 

I feel bad, so i made a handy Spec chart for you!

B18C1 (GSR, USDM):
HP: 170 @ 7600 RPM
Torque: 128 @ 6200 RPM
Redline: 8100 RPM
Compression ratio: 10.0:1

B18C (SIR-G, JDM):
HP: 180 PS (176 HP) @ 7600 RPM
Torque: 17.8 kg-m (129 lbs-ft) @ 6200 RPM
Redline: 8100 RPM
Compression ratio: 10.6:1

B18C (specR) (Type R, JDM):
HP: 200 PS (197 HP) @ 8000 RPM
Torque: 19.0 kg-m (137 lbs-ft) @ 7000 RPM
Redline: 8400 RPM
Compression ratio: 11.1:1

P.S.- you can find all that info here too!

 

wow.. that was nice b18c has different pistons too.. but everything for a usdm gsr will work on it.

 

so would the cams and pistons from a jdm spec b18c fit in my gsr without tons of work??? thanks for all your guy's help

 

yeah.. i'm like 90% sure
