Fuel Pump Advice.....

I personally would, since you sound like your not getting a stand alone fuel system, your pulling from the same rail the injectors are and the pressure CAN be turned up, but there will still be a volume issue.
Also, frankly, I would feel safer with a newer, higher flowing pump matched to a hotwire kit.

I was very impressed with the quality of the Racetronics. I installed their kit on my car about two weeks ago. I bought it at Harris Speed Works, they seemed to have a good price, the shipping is fast, and the customer service is top notch.....

Just get the pump. You've spent a ton of $$ on the car and all of the rest of the stuff you've done to it, why cheap out now? Think of it as cheap insurance for your engine

I have read somewhere on here the stock fuel pump is good to approx 500bhp. not RWHP. I had to upgrade to go over the 100hp jets as the fuel pressure was getting low..... Make sure you get the car on the dyno or use a Wideband O2 to watch the A/F Ratio while on the spray....... You want it to be a tad rich say 11.8 or so..... Read the suggestions that came with your N20 Kit. The jet charts are for a good starting point only....Always check with a Wideband for a good A/F and look at your timing so you can make sure you are pulling enough while on the spray. Good Luck and remember that N2O can be safe as long as you take the time and set it up properly. The sponsers here are a great asset to the site and they will help you get it right......I think I paid somewhere around 250.00 for the Racetronics kit. But don't forget even with the upgraded fuel system you still need to check your A/F and Knock retard......... GL...
