hey man, I'm right with you, I wouldn't expect you to pay that. Ontario is the right place to be checking, they pop up a lot over there out of MA70 cars
r154 is a supra transmission. Depending on what bellhousing this transmission came on a few engines from the MarkIII Supra in North America *more applications in Japan. 7MGTE and 1JZGTE mainly.
But it can be fitted to any M series engine with the 7M bellhousing and any JZ engine with the JZ bellhousing.
