FS: Supercharged 1990 NA w/ 1.8 swap Miata

[OZMDD]

Before I go and pull everything out of the car, I figure I should offer it as a complete car for a week or so in case someone wants to skip the whole "build" thing. I can make more on the part-out, but labor is laborious.

1990 NA Miata, base (manual windows, manual steering rack, power brakes, that's it.) Good clean chassis, straight body with 6/10 paint (red). Car is emissions-exempt, and is currently registered as an antique ($40 every 3 years!) 5mt, open 4.3 diff.

The majority of the car is stock 1990, and is in good working order. Very light chassis to start with.

Upgrades:
- 94-97 1.8 motor swap installed.
- Jackson Racing M45 supercharger kit w/ TDR nose pulley (8psi), metal crossover tube, complete and installed, runs/idles/drives great. Internals are in good condition, bearings are tight and noise-free. Old-style belt tensioner could use upgrading.
- BIPES ACU (timing controller) and Power Card (fuel controller) installed and work great.
- Flyin Miata Stage 1 suspension kit (Tokiko Illumina adjustable shocks w/ lowering springs. Its lowered, but not slammed.
-Car has a couple of Racing Beat chassis braces on it, since it is a 90 w/o any factory add-ons.
-Racing Beat Stainless midpipe and muffler.
- Jackson Racing header (fits under S/C with plenty of clearance)
- Clean black cloth interior in excellent condition, recently-replaced black carpet from a low-mileage car.
- Jackson Racing boost/vacuum gauge in pillar-pod.
- Nice CD player with good speakers
- Push-button start
- Several wheel/tire combos are available to choose from, depending on buyer's budget and needs.

Con's:
-Have not charged A/C since purchase last fall. Not currently blowing cold. Compressor will kick-on when low pressure switch is bypassed, so I think it is just low after sitting for several years prior to my buying it.
- Heater core is bypassed right now. I ran water through it and seemed leak-free, but PO had the water lines routed around it, likely for cooling.
- Many of the wear items on the car (hoses, belts, bushings, etc) are older and will need gradual replacement over the next year or two, as the car sat for a couple years. Nothing is bad or failing, just worn. I've done some updating as I've driven it for the last 6 months, but on an as-needed basis, since I planned to pull it apart and prep for track use.
- 5th gear is a little vague when shifting quickly. Works fine and doesn't pop-out, just has a less-positive engagement than the other gears.
- Dash is cracked in a couple spots.


Talking to people in "the know" about these setups, we think the car is making around 140-150 whp as it sits, and can very easily jump up to 170-190 whp with intercooler, crank pulley upgrade, and bigger injectors. 200+ is do-able with standalone ECU and a good tune on E85. (I do have all of these items for sale separately)

I have had no issues other than a surging idle when the original bypass air hose was collapsed, and it runs a steady 180 water temps all the time (unless you hotlap it at an autocross for 10+ minutes without cooldown on the oem radiator!) Done plenty of street driving, and its reliable and fun. It has the squeaks and rattles you expect from a 25 year old car on performance suspension, but nothing concerning.

Supercharger and performance parts will be removed in 2 weeks and the car put back to stock condition if I don't get any bites.

Asking $3700 for the complete car with street tires/wheels. Willing to negotiate on specific add-ons/take-offs.
