You're going to need a 13B.

Skip the fuel pump & wiring harness, keep the SE lower intake, and go with the racing beat upper with a sidedraft. Maintain the 6 port functionality as well. See if Robert has the intake & carb.

If you are staying n/a the stock harness is just fine. Just follow the rats nest removal tutorial. You could always do the racing beat holley set up as well.

If I drank a beer for everytime I've done this swap, I would have been dead with alcohol poisoning long ago.

You only need the mazdatrix mount if you have solid motor mounts. You can stretch the stock rubber mounts to fit, provided they arn't rotted out.

I recommend the 12A front cover. I just find it easier and cheaper myself.

PM me if you have any questions.
