have you reserached the rod knock issue with the 7m? Most of the time its caused by owner neglect and low oil. BUT on supra forums there are many cases where the cars are well taken care of, oil checked religously, and its completely stock, and rod knock develops. For the money, you can get a 1jz for about the same price. My friend has a 1jz in his mk3 and has had no problems with getting parts for it, that seems alot like an internet myth about bad parts availablty, either way, good luck.
