congrats, you bought a heavy ass underpower supra. dont you worry im not jealous, i would of saved up and waited for a turbo. putting a turbo on the na supras is a waste of money. the motor is not identical to the gte. the pistons, rods, fuel delivery, injectors, a whole lot of things. also, if you plan to go turbo, id say save yourself the headache and swap. and make sure you get the usdm engine, not the jdm.
anyways, i always felt that the supra was very overrated. i love the looks tho, dont get me wrong. but their nothing more than dyno and highway queens.
