hey guys, i just bought a nitrous cam 230/242 114 LSA 544/576 w 1.6rr's and will be spraying a 150 NX wet shot. im debating what i need to do with my fuel system, such as upgrading my injectors and fuel pump. im expecting to be laying around 350rwhp with the cam and who knows how much on the nitrous. what would you guys recommend i upgrade in my fuel system if anything?
thanks
brian

 

You'll need an intake or inline pump. I'd suggest just doing a 255lph intank. Racetronix sells a nice kit.

Injector wise, I'm guess you'll still be able to get away with the stock injectors at that power level, as long as you aren't reving her to 7000 RPM.

 

yeah, one of the local guys has a wlabro 255lph intank that ill probably take off his hand. ill be revving to 6200 rpms so i guess the stock ones should be ok. if not then ill go to the 30# injectors. i just dont want to hurt my motor and id rather be safe than sorry.

Your fuel pump is OK. i have a friend with a 383 and 200 shot and is running a stock fuel pump.

 

I run the Racetronix 340GSS in tank. I would be a bit leery of running a stock pump with nitrous. Alot of guys do.....and alot of them melt thier pistons too. A strong fuel pump is good insurance against fuel starvation, and a piston killing lean condition.
It only take a few hours to install a good intank pump. Why spend all that money on mods, and run the risk of damaging your engine. Good Fuel Pump--$150 Burnt Piston--$1000 or more for parts and labor.

Why take chances??

 

yeah, ill porbably do it in 2 steps, step one will be the cam and valvetrain, and step two will be doing an intank fuel pump and then the nitrous. thanks for all your help!

I'm using the Walbro 255lph in-tank pump & Im having no problems with a 175 shot...

 

thats the pump i have lined up to install. are you using larger injectors on your setup with the walbro?
