Some questions about going FI

Low mount is going to be better. Twins are really better on a v engine from a packaging standpoint, but you have to pull the motor to install.

Keeping a hot turbo in the engine bay of a car with cooling issues stock is a bad idea, not to mention I'm not a fan of how you have to run the hot side piping. Low and out of the engine bay is better from a heat and piping standpoint.

Stock gtr injectors are 570cc, paired with a 255 you will have more than enough fuel for 500whp on gas. (I made over 600whp on a low compression vq with the exact setup). I personally think the stock y pipe and cat back would be fine for 500hp. Obviously there would be benefits on going bigger.

Still on stock internals?

This is from my friend's 370z that was just finished. It made for 500 whp at 7 psi but I am always concerned about dirt going in the turbo or even bottoming out.

That's where mine is give or take a couple inches. Filter protects the intact and the turbo itself sits above the subframe so no bottoming out.

Check out my build thread. It has a lot of detail.
