7mgte Twin Turbo?
 

I was on eabay and i found a twin turbo manifold for a 7mgte. I was wondering on how much of a power upgrade would this be and would you have to program the ECU.

that would take a shit load of mods that manifold is a one off so lots of r and d to figure out how to setup i was looking at it and talked to my tech guy he told me to stay clear so i did i pickup a huge turbo instead did a 3" exaust from my 3.5" downpipe back my car with lots of work could easily hit 700whp so do some research think this way two turbos shit 2 of alot of things so scratch your head and do some thinkin on really what u want in the end

well right now i have a huge rod knock, so im still thinking on what i wanna do. I m thinking of junking the N/A and putting a 1jz in, im not sureif you can build up the N/A up to 300 hp without changing the internals. I dont know what im doing yet, any suggestions.
