MS w/ a 00 1.8 swapped into a 90 NA - can I PnP it?
I have read several different threads about 1) swapping the NB motor into an NA and using the NA sensors and electronics, and 2) running MS in parallel and as a standalone for a 99-00 car.
Here is my situation - I have a 90 miata that is going to be a track toy (interior is stripped, roll cage is installed, hardtop will be bolted on once I roll on some brightside polyurethane). The car has no a/c, and I will be gutting the PS rack and removing that system as well. I was planning on turbocharging the 1.6, but a good deal has come up locally for a 1.8 out of a 2000, so I am wanting to pick this up, and then either buy a BEGI kit or piece something similar together myself and boost the 1.8 instead. The new motor doesn't have an ECU, and the wiring harness has been cut (not sure at what point, but I am going to presume it will be useless for running back into the car to connect an ECU/EMS). Can I use the 1.6 harness and a MSPnP, swapping the cam sensor and other sensors as needed from the 1.6 to the 1.8, or will I need to basically make my own harness from the one that is cut and run a DIY MS setup? Thanks in advance.

Your 1.6 harness will be fine. You will need to run an extra wire for the 1.8's variable tps, another wire for the AFM delete (both of which are explained in the DIY PNP manual) and a last wire to run the VICS solenoid. None of the extra wires are difficult to do but it would be a good idea to talk to Jerry a bout the wire connection to the PNP for the VICS.

I have the variable tps from a 94 motor on my car currently and i did not need to run an extra wire for it and it works fine. The 90-93 harness which is what i kept in my car when installing the 94 motor provides the wiring you'll need to run the TPS. The pin on the TPS that does not have a wire for it from the harness is i believe an on off switch for an off throttle signal to help with idle on the stock ecu.
Boileralum, not to sure on this but there may be an issue with the CAS signal from the 00 motor maybe someone here could clarify.

Matt's correct that without modification the MSPNP isn't setup for controlling VICS as the 90-93 isn't a VICS car. That's not to say you couldn't DIY a relay control circuit and then have both EBC and VICS control (it's fairly simple) and we designed the MSPNP with the DIYer in mind to be able to add functionality, but we're not doing alot of modification to the MSPNP units. We designed them for the PNPer, but kept the DIYer in mind so you can do these sorts of things if you want to. Check the manual for more info.

There isn't one; you'd want to leave that disconnected. Although the boost control output could be repurposed for a general on/off output. So it's your call - you can have the MSPNP control VICS or boost, but not both.
The MSPNP can be modified to use a variable TPS easily enough, though.

Thanks for the help from the rest of you. I figure worst case scenario I can run an MSD pill for the VICS, or just run a manual boost controller. I don't think I will ever register the car for the street, so having one boost setting won't be a big detractor. I believe I will need to run the CAM angle sensor of my 1.6, which isn't a big deal either.
Looks like I need to read through the DIY manual so I can wrap my head around it all. Thanks!

Will do. Have I met you before? Are you on 502streetscene?
