The new style PTU can handle the handle the heat. You're not gaining any extra HP. There are a million (well not exactly lol) Z32's with PTU's in the stock location for 20+yrs running fine. And second that, the idea of cutting up a brand new efi to run it into the foot well is bothersome to me. Something I wouldnt do. But I have undone new efi's to put PTU on the side of the engine bay... that isnt so bad. You only have to unwrap the new efi in the front.
