HAving an NA Supra and tring to make it turbo isnt the best may to go. Get a turbo modle. The 7MGTE is more than capable of making 300hp. Mine is making 265hp with very little parts and relitivley low boost. The 1JZ swap isn't the easyest to do and the motors are getting old and hard to fine. But they are much stronger than the 7MGTE motor. Like I said get a Turbo modle, doing a 1JZ swap will be much easier. Also you will needto find one 89-92 the subframe is different as well as the mounts.
