    Anyone know if they make a NOS system?

    Just wanted to ask the question about a small NO2 system for the northstar. I dont care if it's a sneaky pete just looking to do a little motor mod. A 50 to 75 hp system would be more than enough. Any ideas?

    There used to be some pics of a Seville w/nitrous system on it in our gallery but I can't find them. Needless to say, yeah they are available.

    Comments: What nitrous kit/setup do you recommend for a 1996 Cadillac Seville STS with the Northstar 4.6L DOHC engine?

    Thanks for your inquiry. We do offer a Nitrous system for your vehicle. Part # 20920 is designed for your car and is adjustable from 50-150 hp. The stage one EFI comes complete with 10lb bottle, D-4 feed line, bottle brackets, fuel and nitrous solenoids (with a lifetime warranty), wide open throttle switch, patented shark nozzle, 50,75,100,150 hp settings, 60 Amp relay, wiring harness, Stainless Steel lines, all mounting hardware, switches and detailed instructions. The only modification needed to run this system is to upgrade your spark plugs. You will need to go 1-2 steps colder, non-platinum, and gap the plugs at .035. For pricing please check out our website for a dealer near you.
    If you have any more questions please let us know. Thanks again for e-mailing us.

    Cost is around $500.
    Definitely change your fuel pressure regulator before installing, since backfires are one symptom of the FPR going out, and can be very bad on nitrous.
