God it's been awhile.

I think the JDM GSR may have different cams, but don't quote me on that.

No knock sensor on JDM motors.

Most JDM motors have different pistons that are higher compression, but I actually think the GSR may be the same.

They are pretty much the same thing.

FFS Tech | B-series Piston Check

more than likely you can find minimal cam profile differences and prob a slightly more aggressive P72 ECU tune

biggest differences i know of is the slight compression difference and often jdm engines do not have a vtec pressure sensor.
