Running a JDM motor in IT Honda

[Chip42]

If the JDM block is identical to the US spec version, he can use it and swap the US spec lower compression pistons in.

even if everything else is the same, the block lacks the "1" in the desingation stamp (about an inch under the head, bell housing side, flat area facing you) so it'd be hard to defend it in an ARRC win type scenario.

regionals? run it if you have no other viable option.
