Need some advice on Fuel Pump and Injectors for Nitrous

V8Killer · 05-24-2013, 12:35 AM

Just like the title says guys. I am moving to a 150 shot of nitrous and wanted to know if anybody has some input on upgrades for the fuel pump and injectors.

Don't think an injector or fuel pump is needed at this level but anything bigger would need and upgrade.

You won't know until you find out your fuel pressure with those jets and calculate your injector duty cycle.

Not many of us spraying here so info is scarce here.

Nissan 370Z 255 LPH Fuel Pump - Walbro - TREperformance.com

This is what I have found so far. I hate doing trial and error but it seems to be the only way with only few spraying the 370z.

I was fine with a 150 shot on my 350z. Stock injectors and pump. Never had a single problem. I just had ngk 1 step colder plugs and that was about it. I never got a tune and was spraying for about a year and a half. GL!

I actually blew up my Integra swapping my fuel pump to a Walbro 255lph and not running the fuel lines correctly lol. I installed my FPR on the rail and of course had the fuel connection spliced before that....Simply put, too much pressure with the fuel jes equaled super rich and BOOM! Basically melted a piston lol.
