I am getting about ready to order my nitrous kit, and was wondering do I need a fuel pump? My car has 125k miles on it. I do plan on upgrading to the Walbro 255 within the next month or two, but was wondering if I would be fine with my stocker for now. My car only has a few bolt ons. Nitrous will be the biggest thing its ever seen. BTW, i will be running a 100 shot with the Harris Speed Works kit.

 

Make sure you get the FPSS and if your pump is going out or cant handle it atleast you will save your motor. You should fine as far as getting enough fuel to the motor with the stocker but upgrading is always a good idea.

 

Awesome. Yeah a FPSS is at the top of my list of things to buy with the kit.

 

You could always test the fuel pump with a fuel pressure gauge. If it can't keep up with fuel delivery when the car is off the juice, it definitely won't keep up on the juice. But as mentioned above, a fuel pressure safety switch is cheap insurance. Also, as long as the stocker pump is healthy, it shouldn't have trouble with a 100 shot.
