cuz you got the D16Z6 and the D16Y8, same block, dif heads
and you can probably get a D16 from Japan
so there would be such a thing as a JDM D16
but i think it would have the same hp and torque
that's not necessarily true.
The USDM D15B7 is a nonVTEC motor with about 107 chp.
The JDM D15B is a VTEC motor with about 130 chp.
Although they are both D15, the D15B has a longer stroke and higher compression. The intake runners are a bit larger too.
It's really just the generation/model of the motor. I don't think they have as much meaning as the first 3 digits in the code.
I've never heard of a JDM D16Z6. The JDM equiv. is like the D15B or the ZC.
All JDM motors that I've encountered do not have the final digit. For example B18C, D15B, B16A, etc.
hih
