Default help me figure out what i bought, please.

and yes, ill need spoon fed. i have no idea what i don't know yet.

long story short, i bought this car: https://grassrootsmotorsports.com/fo.../174429/page1/
supposedly an fm2 kit running on AEM management. as discussed in the thread, it exited the road at a high rate of speed into multiple immovable objects. the PO then started to tear down and rebody the car, and life happened. 3 years later, i bought it. (same screenname over there, and on every forum!)

so, im trying to figure out what's actually there. and what's missing. and what i need to do next. my plan is to scab the wreck back together enough to drive around the neighborhood and make sure everything is healthy. then, assuming it is, drive back to back with my v6 drivetrain car and see which one i like better. then combine the best aspects of both cars. like i said, general plan. i want a less racecar miata again....

anyway, ive been getting it cleaned out and starting to assess all the stuff the PO sent with me and what is there. ill start with the engine bay pictures i took today. i moved the air intake and maf from the turbo inlet to the throttle body side so the car would run and drive itself onto the trailer yesterday. so i know where that goes! I've just never seen that particular intake setup with a turbo anywhere. the blowoff valve(?) doesn't seem to have anywhere to go. it may have been on the old intercooler piping, but that's gone. the manifold has some odd extra fuel rail and injectors that aren't hooked up to anything. there's an unplugged sensor and no corresponding wiring in the piping that had gone to the intercooler. turbo seems to be a Garett, but didn't find any markings other than what's pictured, and the manifold is cast with flyin miata

so, what do i have in the engine bay? what do i need to know about it, and where's a good place to start my education on it? i know its based somewhere in flying miata parts, but cant seem to line it up with any of they're website stuff

nest is engine management stuff. im a total newb here. its currently running on this AEM unit. how can i learn what it is, and what it does/doesn't do?

in the trunk was what i believe is a megasquirt plug and play and a coil on plug conversion kit. any idea how to figure out just what this stuff is?

Beyond the obvious of needing a new chassis and massive amount of maintenance, you bought a 8
injector setup, back when the OE ecu controlled the stock injectors, and an aftermarket ECU, originally Link, controlled larger auxiliary injectors only when in boost. Worked, but unnecessarily complicated with today’s technology. ID1050x’s idle better than the 265cc injectors your car came with, for example.

rip the engine out, check comp/leak down, reseal it, replace all rubber components, injectors, intake manifold, and ECU. You’re going to have a ton of issues and questions with this setup, non of which you'll get a lot of answers for.

that looks Like a fab9 COP setup, go ahead and throw that in the garbage. Take some more pictures of the MS, you may be ok with that, if all other wiring is ok. ::fingers crossed::
