Jpec was the same, except tuned for Japan's 112 octane and less emission requirements.

I have a J-Spec, but not installed yet. Got it from FC3S (QJS Engines). The air pump is different, and I hear the harness and ECU were slightly different also. The turbo looks identical. The blocks are identical (now's a fine time to find out they weren't) I'm told.

As soon as I get my motor stand bracket from Mazdatrix, I'll start tearing it down for the transplant.

Identical, except that j-specs have no egr provisions.
