MSPNP with 1.8L motor in 1990 Car
So I'm contemplating putting a megasquirt pnp in my 1990 miata. I had a custom turbo setup for my 1.6L, but due to unforseen circumstances (detonated cylinder 4), I'm rethinking things. My setup before the detonation was like this:
Custom manifold and downpipe
16G turbo with small compressor(not ebay)
Supra TT 440CC injectors
Vent to atmosphere BOV
Toyota COP conversion
Silicone Intakes barrel style air / water intercooler
AEM F/iC piggyback
Gizzmo IBC Boost Controller
2.5" Aluminum charge piping and intake with AEM Dryflow filter
Full MAF Delete via F/iC
So with the 1.8 motor, I know I'll need to have another manifold made for me, which isn't a super big deal, but I'm also thinking I want to try a different engine management system. The MSPNP certainly fits into my budget, which is quite small now since I had to buy a new motor, but I have a few concerns / questions. So here goes:
1. The 94 1.8L is from a 5spd, and I'm assuming has a proper TPS, unlike my 5spd 1.6 motor. Will the MSPNP be able to recognize this, using the stock 1.6 wiring harness?
2. Am I losing anything from having the 1.6L wiring harness / 1.6 MSPNP that I might get from having a 1.8 harness and the 1.8 MSPNP? Should I be doing a complete conversion?
Thanks folks! I've used Haltech, Hydra, and AEM EMS on customer cars, but haven't used MS. Sort of nervous about the whole thing.
