Monster Miatas are, in the scheme of things, relatively common. V8 swap kits have been available almost since the Miata itself launched. This, however, is the only V12 swap I’ve heard of.
This is a Jaguar V12 and the seller claims it has internal mods in addition to the downdraft carbs shown in the images. This is backed by a T-5 manual trans. V12 + manual + roadster? We like! That being said, the styling choices were interesting, to say the least. It would be interesting to see what the front:rear weight balance looks like now…

Apparently, that’s a boat in the background, so this isn’t quite as odd as I first thought. That being said, the hood is a nice, subtle touch.
This view doesn’t look so weird. Roll bar is probably a very good idea here.
At least a top is included.
Interior has a full suite of gauges in some sort of custom center stack.
Here’s the engine with those groovy carbs.
Looks like this took some serious canopener work.

XTREME !!!! This Mazda Miata cost over $20,000 to build in 1995, plus basic car cost. The V12 Jaguar engine not only has 6 downdraft Weber exact copy clone carbs (Made by EMPI), it has been ported and polished, 12.5:1 compression, custom pistons, balanced flywheel, modified crankshaft, aluminum racing radiator, AND THE MOST INSANE CUSTOM EXHAUST HEADERS – seriously expensive !!! The frame has been professionally modified and strengthened. Front cross member supports the V12 nicely.
I drove this car about 90 miles to this storage location 3 years ago and parked it. It ran fine, but it was misfiring slightly at that time. Now it does not start. Generally when a Jag V12 has a misfire it indicates a blown head gasket. I believe this is the problem, but there may be other issues. The engine / car was built in Florida. I drove it for a couple of radical months in the Vegas area. It is totally insane !! Forget first gear. Spins wheels easily in 3rd gear – massive torque and horsepower. Makes all other V12 Jags look wimpy, and I own two 6.0 XJS. I had planned to install a Ford rear axle with 2:87 gears, or similar.
There is a stereo face plate included with the sale. The top is shot and the interior needs cosmetics. Tires poor. Windshield has crack from my hitting it accidentally. No windshield wipers – no room. Clutch and gear box are like new. The Tokico coil over load leveler shocks are high value. Car sits perfectly flat and steering is tight. Exhaust is 3 inch and in excellent condition. 5 speed T-5 trans is perfect.
Replacement value on the 6 EMPI double downdraft carbs, with K&N air cleaners, velocity stacks, linkage and manifolds – if you could ever find a set of manifolds for a Jag V12 – would exceed $4,000.
I have held onto this rocket for a couple of years, hoping to get the time to build it out. Not happening – no time. The race engine, without the carbs, is worth almost double the asking price. I may be willing to separate and just sell the carbs,or the race engine and T-5. Best deal is to buy the package. And finish putting together The Worlds’ Wildest Miata. Questions?
