Hi. Nice to see you have a supra. The 7mgte block tend to give up and that motor you have now WILL give up again. The 7M block was never meant to be turbo. They just threw lower compression piston with few changes and threw a turbo on. Yes the record 7m motor makes over 900whp but they do not last very long. For the money you are about to spend on that motor I recommend swapping a 1JZ or even a 2jz into that car. 1JZ is the best budget since in japan the 1jz was the MK3's power plant that the USA was never given.
Stock internals on a 7m reliability is about 400whp. Anything past that and the car is on its slow death. 1JZ stock internal reliability is in the 600s and 2jz are in the 800s. Swap experiences means nothing to me unless you know the motors by heart and what it can and can not do. You are just wasting money on that 7m block. I have done a few Supra builds (not swaps) in the past 3-4 years and I know for a fact I have had more 7m BUILT fail over time over 1jz and 2jz put together a lone and its just pure fact that those motor are not well balance. Now people do say money can make them work... Well 8 grand for a good 7m over a stock 1jz that cost 2 grand with tranny can do the same.
All in all if you are going to get that 7m block build DO NOT cheap out and put the best money you have and get it balanced with the best headgasket you can and tq it to the new specification and not the old one that has caused so many bhg on 7m supras.
I am retired from cars and no longer work on cars but if you need help and question you are welcome to pm me. The thing about supras is cheap out and people will be laughing at you as they drive by on the highway.
