V12 from Two 1JZ Engines

V12 from two inline-six motors

I will be the first person to say I hope this is real and will see the finish line. Someone is developing a quad-turbo V12 using two Toyota 2JZ 1JZ inline-six engines. Combining two inline-six engines into a V formation has to be incredibly difficult. I can’t wait to see further progress.

Updated: I added two more images. The heads appear to be 1JZ. The engine is going into a custom tube-frame chassis. More info coming.

    • I agree. The biggest worry I have (besides being a hoax) is it might be a side project for a someone. So they only work on it when the builder has some time. I hope I am completely totally wrong and this will be completed.

        Are you sure its not going to be one of those table builds? Doesn’t look like a garage or workshop and his tools look like that of a carpenters, could ‘ve wrong, why has he bolted the turbos on before fitting other important parts. and even bolted the turbos yo the supporting frame.

        • There really is not enough info right now. Maybe this was just setup for the photo. Or maybe the guy is really working on this but just wanted a cool photo? I am trying to find out.

    thats not a 2jz or a JZ for that matter.. looks like a 1g-gte to me.. the 1g-gte had the turbos setup liek this as well cause those ports are not jz ports and the heads are not js heads.. so thats not a jz engine.

  2. […] This amazing engine builder is back with more progress on his V12 being made from combining two Toyota Supra inline-six engines. Since our last update the builder has mated the engine to the transaxle. A frame mockup is being built using PVC to see how everything with fit. The cardboard box is half of a planned fuel tank. Shifting linkage is being built to handle the six-speed. The engine will be twin-turbocharged with two Garrett GTX 3076 models. If you would like to read how we go here you can view our previous update and the original article. […]

    My only comment – Why?
    Toyota has had a V12 engine in the flagship Century model since 1996 and they are readily available from JDM parts wholesalers. Builders in Australia have been souping them up for over a decade.
