i have the intake, turbo piping, intercooler, twin turbos. do i need to change the trans or wire harness. any help would be great

 

If you are thinking about putting the 2jzgte twin turboes on a 2jzge head, you better be ready for some custom work.
The turbo manifold bolt pattern is not the same.

You will also need to tap a location to supply oil to both turboes.

You will be better of going the NA-T route with a single turbo setup if you can.
