I read through but his is regarding a aristo motor. I think I'd rather go na-t and get a US 2jzge. Mostly because I would think this would be the easier route being my first turbo'd car.

 

I guess what I mainly need to know is whats the easiest way to wire a 2jz into a gs400. I know about the mounts, bell housing, and manifold. But what I'm not sure about is do I need an ecu from a gs300 and would it need to be rewired to work with my keys. Or, would an external engine management system be the best route as I would be turboing anyway? Even still I have no clue if this is even possible.

 

Now this thread scared the crap outta me. I was going to do mines at 100k but i guess 90k is fine too after thinking about the price for a blown motor.
