Well, I installed a nitrous kit from NOS this weekend. Didn't go too well. I was starting with a dry 50shot. The spray was installed before the Mafs like the Nitrous sticky said. Well, before the run, I tested it, with the intake assembly off, powered her up and temporarly grounded the second solenoid (the one that's hooked up to the fuel pressure switch), turned on the arm switch and floored it and you can hear and see the spray. So then when I hooked everything back up and took it for a test drive. Oh by the way I have some NGK 1 step colder plugs with MSD 6a with SS Coilpack running Magnecor Wires. Anyway, when I test drove it, it felt like nothing, absolutely nothing, just as if I never installed nitrous in the first place. Well, I thought maybe something didn't work right but as soon as I came to a stop sign, my car has a really bad idle, and the motor shakes quite badly. I drove her home and took a look under the hood. Nothing looked wrong, nothing smelled like burning.

When I took out the spark plugs, they were pretty hard to get out and hard to put back in. They were fouled with what looks like cooked on carbon. I had an extra set of NGK Copper plugs gapped at .040 inches. The Idle's still bad and with a slight lack of power. Anyone have any Idea's on what I could of done wrong?? Any info would be greatly appreciated.

Well... if it's the MAFS that's screwed... it's no longer a free kit!

Anyway... all you have to do to make it a wet kit... is buy a wet nozzle (the NX Shark is awesome), fuel solenoid, a T splitter, and some fuel lines. Just wire it into the N2O solenoid.

yeah, I don't know much about a wet kit, but damage is done so looks like I'll be gearing towards an SR
