When swapping a Toyota JZ engine into your project, the options for transmissions to go along with it seem to be never ending these days. Here's another one for ya. The BMW DCT transmission is a spectacular piece of engineering, allowing you to shift gears in a scant 50 milliseconds (the average driver can shift gears around 1 second on a typical H-pattern gearbox). This adapter plate and accompanying flywheel will allow you to bolt up the DCT transmission found behind the 6-cylinder BMW engine to your Toyota 1JZ/2JZ engine.
