You could always do a 7mgte engine swap the only thing that really has to be done it run the new wiring harness... but you have to find the engine, ecu, wiring harness for the year engine, and then problem you will have to find a turbo and such. But i would be cheaper then putting in a 1jz, but with all 7mgte your still going to have to replace the headgasket after a while cause it is going to blow.
