LS Swapped: 1992 Mazda Miata Project – Sold!
If you’ve always wanted to stuff a V8 into the wonderfully handling NA Mazda chassis but never wanted to buy someone’s finished car, this 1992 Miata project listed on Craigslist in Walnutport, Pennsylvania with an asking price of $15,000 may be your ticket. Using a stock Mazda as a proxy, the seller is asking $900 more than the #2 “Excellent” estimate of $14,100 shown in the Hagerty Insurance Online Valuation Tool so you’ll have to decide whether the powertrain work completed to date is worth that much of a premium.
Here’s the seller’s description:
“Up for sale is a LS1 swapped Mazda Miata.
I did not perform the swap myself nor did the person I bought it from so complete details are not the best. The car was built more for the track but I had intended to make it more of a street car. It was difficult for me to find time to work on it and I have since bought another car so I am ready to let go of this one.
The LS1 and T56 are a pull out from a WS-6. The previous owner told me there was about 60k miles on the set up. I would estimate less than 70k miles are currently on the car but there is no odometer. This car was on the dyno making 370hp. It has a cam, Fast intake and I’m sure a few other items.
The engine swap uses the Boss Frog kit and V8 roadsters trans and diff mounts. It has a Ford 8.8 diff with posi trac. Driveshaft shop axles. Boss Frog shorty headers are installed and the rest of the exhaust is pieced together. The exhaust could be nicer (I am not a great welder!) but it is much better than how I received it with with no mufflers and side exit out the rear quarters and all stitch welded together. This is why there are holes in the rear quarters. Pipe is welded in here and it is done pretty well. I planned on covering this up with some kicker panels.
The body is in great shape as this was originally a southern car. No rust or rocker rot that ruins Miatas of the northeast. The previous owner shipped it up to the northeast. One thing to mention is it has a different hard top on than the pictures show. The top is painted black.
This car has mostly been sitting for the last several years as I have focused on other things. It does have some sort of issue with the MAP sensor. I bought a new one and played with it for a few minutes but did not really figure it out. Not sure how this developed as it just happened one day after sitting. The car still starts and drives but the idle will hang very high so you would need to trailer it.
I have lots of extra parts for this car which I kept when parting out two other NA Miatas with the intentions of installing them. There is no heat or AC in the car but I do have all of these parts. This can go with the sale too if desired.
Title is clean and in my name.“
