hello wonder if somebody could help me with a gearbox problem. i have a 7mgte with 800 hp. need a new gearbox that can handle that kind of power. is there somebody that have made a swap plate for the 2jzgte gearbox to fit my 7mgte engine? help me please.

2jz tranny won't work, the best bet is to find a good place that can rebuild your R154 stronger. The tranny should take it quite well, the clutch is the more likely thing that will go out, and any tranny will blow if you miss a shift with that much power...
