Does anyone know where I coud find technical specs on the '98+spec JDM type R engine?

part 2- does anyone know what the differences are between the above mentioned B18C block and the USDM GSR B18C... Bore, stroke, pistons, crank etc? directions on where to find that info would also be greatly appreciated.

 

You might want to try the "All Motor" forum.

Here is some info to get you started anyways:
Both motors have the same bore and stroke.
The JDM 98 Spec ITR motor has 11.2:1 compression and its crank has more counter weight.
The USDM GSR motor has 10:1 compression and its crank has less counter weight.

 

What! honda tech has other forums?

Thanks, I'll try there

Just trying to see if i could squeeze through a loophole / not really a loophole - just trying to be creative. I don't expect to be able to, but investigating non the less.
