i sold my old mustang and got a good amount of cash for it. my friend has a 1990 supra with the 1J in the engine wich he bought from some other guy. can you do the swap with no problem or are there many mods that have to be done with the car. i heard that the 1j has more hp and overall a better engine, is this right or should i go for a supra with the 7m? ppllleease help me out.. thanks
