This 1990 Mazda Miata is a very early first-generation NA chassis code example that’s lost its original 1.6 liter 116 HP twin-cam four for an unspecified small block Ford V8 topped with a massive 6-71 blower. This sends power to a limited-slip equipped 8″ rear via a BorgWarner T-5 5-speed, and while the ad provides very little additional info, the car definitely looks to be real. Find it here on Craigslist in Fallbrook, California for $18,500. Special thanks to BaT reader PQM for this submission.

The car’s blacked-out hood and vinyl nose cover suggest it may have been an accident victim, which might explain the crazy idea of fitting it with this motor. It’s said to have a clean title, but there’s no word on registration, possibly for fairly obvious reasons relating to smogability.

The Detroit Diesel 6-71-style blower appears to be topped with dual Holley four-barrel carbs, and underneath there’s a SBF that’s likely to be a 302. Unfortunately the ad doesn’t divulge much, though we do know that the above-mentioned LSD 8″ rear end drives the rears through Chrysler 300M axles.

Inside, two vents have been deleted to house water temp and boost gauges, but apart from a different shifter necessitated by the trans swap (and an old aftermarket CD deck), everything looks to be mostly stock inside. Aluminum heads are noted as well, the seller summing things up saying simply “This thing rocks!”
