My friend is seriously thinking about getting a 323 gtx, which has a lovely little B6T engine like 1.6 miata's B6ZE. I know there are differences like the timing (mechanical advance distributor), 7.9:1 compression, and the most obvious one, the turbo, but all in all they are pretty similar correct?

I really don't know that much about the workings of ecu's and megasquirt, and will myself probably get the 1.8 mspnp because I don't like doing hours upon hours of wiring. But does anyone know how hard it would be to make a MS that would work with the 323 gtx, or to adapt a miata ms? I would guess that it would have to be custom made (braineack?) and mostly custom wired unless there is some kind of miracle and they share a harness. Is this idea even close to reasonable? Or would it just be a huge pain in the *** and more like making a MS from scratch?

 

I think it should be relatively straightforward. He can even leave his distributor on initially and tune the MS for fuel-only. Then once comfortable he can get it working in spark mode also. All he really needs is a reliable set of wiring diagrams and a bit of common sense.

 

Will probably require a bit more work but it wont be rocket science. Scott or Chad can build you the squirt, but the harness you may have to do yourself.

 

If it were me i'd build a MS and boomslang myself, then figure out the spark and tach mods.
