I am not sure about in a Tacoma but the swap is pretty easy in a pre taco truck. Like in a late 90s 4Runner. It's basically the bellhousing from a Supra and the 7M, it all bolts together. The motor mounts from a 5M in a pre-86.5 make it bolt right in. Then you just have to do something with the cooling fan/radiator. The last part is the ECM which I think isn't that hard but I don't know the details on it.
It's an easier swap than a Chevy.
But I am not sure on the Taco.
