V12 Built By Joining Two Toyota Supra Engines, a Retired Engineer’s Pension

Modular engine architectures. This is one of the important goals of the automotive industry, with German automakers leading this metallic LEGO game. Nonetheless, one US car enthusiasts has taken this into his own hands, albeit working on JDM delights. The man is a recently retired mechanical engineer who’s passion is as strong as ever and he’s decided to join a pair of Toyota Supra engines in order to obtain a V12 unit.

It all started with two 2.5-liter 1JZ-GTE straight six Supra hearts, which were joined together and an angle of 120 degrees, with the result being labeled as a... Frankenstein V12.

While the blocks came from Toyota, all the tech goodies in the lower part of the resulting V12, such as the crankshaft and the oil pan run deep into DIY territory.

The engineers somehow used to work from home, with his former employer fitting his garage with all sorts of tools and now the man is putting them into the service of his passion. Still, such a project eats up tons of time, so the thing is a long way from being completed.

The V12 has come a long way since the initial phase of the project - for instance, the exhaust headers were initially placed in the conventional outboard position, completely different to their current position.

As you can imagine, such a custom powerplant can only run a bespoke ECU. We’re not sure what the starting point is, but we do know the guy will be handling the programming himself.

The car around the V12

One very important question that remains unanswered regards the vehicle that will surround the powerplant. At the moment, there seem to be to pathways. The first would see a custom tubular frame chassis hosting the vee twelve, while the engineer could also install it in a 1955 Chevy pickup shell he has lying around. We hope the progress speeds up so we can get our hands on a massive update. What can we say, once an engineer, always an engineer.
