V12-powered MGB Is One Crazy Build

Car

Daft would be the proper term to use for this build, because it would take a crazy sort of mindset to envision a V12 Jaguar engine in an MGB. Factor in a fully fabricated tube chassis and 4-link rear suspension and you get to appreciate the mad scientist mindset a car nut would need to go through the build.

Mark Sawatsky of Canada is an avid autocrosser, and an old MGB and Jaguar V12 was lying around in his garage, so he decided to build it up to enter in the EMod class in the autocross series he was running in. Despite being MGB-bodied, this car actually has nothing left of its English car origins.

Engine

Displacing 5.3 liters, the V12 Jag engine is still a carbureted version, which limits its horsepower to 290 at 6,000 rpm. Transmission will be a 5-speed using a custom bellhousing to mate it to the Jag V12. Racing details abound on this car, like the aforementioned rear 4-link and a front suspension that uses Ohlins shocks mounted on a pushrod system. From the transmission, power will go to a Ford 9-inch diff that will have 13-inch slicks on opposite ends.

In a 2300 pound car like this, performance calculations estimate the 0-60 sprint in under 4.3 seconds with quarter mile times in the 12.5s. Despite being a successful build, the latest news is that the engine has run into problems and the owner may defer a rebuild for now. But enough videos were taken of the car while it was running, and here’s a couple for our readers to view.
