It's the same engine as z and g35 right? So do you think it would be possible to maybe build an engine and put Greedy twin turbo in it? Is it bad idea?

 

It's the same engine, but it isn't the same engine compartment. In other words, there may be some real issues getting the kit to fit properly.

Yeah, the engine compartment is bigger, but it is laid out a bit differently so the kit plumbing might not work. You'd really need to get a TT 350Z/G35 and a FX35 side by side and do some tape measure work to see if the plumbing will all hook up.
