NA6 Miata complete drivetrain swap
 

Hey Guys!

So I was recently in an accident, long story but the other person was completely at fault. My shell is trash now, the whole passenger side of the chassis has been crumpled. But besides the radiator the entire driveline is perfect. It's a 1990 1.6 5 speed, with a voodoo 2 turbo kit. My plan is to swap the whole engine, trans, and diff into another NA6 miata. I found a 1991 NA6 with a hardtop, and it is perfect for my purposes (mostly because it is really cheap) other than the fact it is an automatic. I know the whole engine and drivetrain will swap right in, but my question is will I have to modify the automatic car's wiring harness, or will it be plug and play? if not, would it be easier to modify the harness or just swap my entire 5 speed harness?

Thanks! I'll be sure to post a build thread as soon as I get started.

I swapped an auto dash into my manual, there is at least 1 extra connector, i just left it open. IIRC there is only 1 wiring diagram for this car, so you may be good with the harness, but should probably use the manual ECU.

Make sure you align the PPF per the service manual.
