i have a 2000 z28 m6 it dynoed 375rwhp and 366rwtq.
i have a NX Wet EFI kit i want to put on... what all do i need to safely run this kit between 75hp- 150hp. do i need a fuel pressure regulator if so what one do i use with the stock rail. i know i need a window switch, but do i need a fuel pump?? if so what do i need. thanks

anything else would be appreciated

 

Tttttt......

 

First off, what are your current mods to put down 375rwhp? You would need the window switch, and a fuel pressure safety switch. I am not sure how much hp our stock pump can support, but if you have the money you midaswell get a new Walbro just for performance sake. As for running 75-150, you are pretty safe on the ls1 with those shots. I am running 100 shot on my ls1, no fpss (fule pressure safty switch) yet, and when I first put it on I didnt even have a window switch. All the 'add ons' are just safty measures, and you can survive without them...its just not recomended.

i have a tr224 .561 112LSA cam, LT's, spec stage III, 4.56 gears 9" ford, all suspension mods rear, LS6 intake, lid etc...

As far as fuel pressure reg. goes i dont need one then?????

 

On the shot that you are looking to put on, I wouldnt think so. Personally, I am not putting one on mine. But then again, my ls1 is cam-less. Hopefully someone else with more juice experiance than me can add some insight. I dont think you will need it, but if it makes you feel better and you feel you need it, then by all means put it on. It surely cant hurt if you have it.
