My post from a recent thread. May be usefull
A proper, and safe setup will cost you 800-1200 bucks new. Putting a $400 dollar push button nitrous kit will make you go fast. But it will make your engine go fast too. And if your spinning tires uncontrolled, it will be a fast trip to a body shop.
One great setup:
Wide Band A/f Meter $250
(You can get a switch for some meters that will cut off your nitrous if your A/f passes a pre-determined value 13.5 or leaner is considered dangerous.)
(AFX makes a O2 Sensor compatible with Leaded Race Fuels. Your not spraying unless your fuel is high octane right!!!!)
On/Off Toggle Switch $8
(No accidental activation of solenoids, Prevents voltage leaking)
NOS EFI Fuel Pressure Safety Switch $60
(cuts off nitrous if fuel pressure drops)
MSD RPM Activated Window Switch $130
(Push button LED On/OFF Rpm window switch)
NOS Wide-Open Throttle Switches
(only sprays at WOT)
Hurst Or B&M T-Handle Shifter with button $40
(Immediatle access to cut off or activiate nitrous at your fingertips)
(Good to allow spray only when your falling behind a little, And to immediatly cut off if the truck gets loose or something unexpected happens.)
Progressive 2 Stage Nitrous Controller $235
(Pulse width progressive ramp for nitrous/fuel to prevent traction loss and lower ET's)
Auxillary Nitrous solenoid $100
(prevents nitrous leak while parked, ensures when you release the button, the nitrous stops)
Purge Solenoid $75
(air or Nos vapor in the lines will cause the car to bog and run rich for a second until liquid Nos reaches the solenoid)
(Cools the system and looks cool
Plugs 2 steps colder $30
(Short ground electrode is as important as colder heat range. Shorter the electrode the quicker heat is wicked away. This prevents detonation.)
Assorted Nitrous/fuel Jets $20
(Dial in your safe nitrous/fuel, Eliminates your computers need to spray more fuel through your stock system if you can compensate at the nozzle)
Nitrous Pressure Gauge $30
(keeping the nitrous bottle pressure consistant keeps your runs and your A/F rations consistant and that is safe
Bottle Heater $130
(ask any baby, cold bottle suck
Remote bottle opener $175
(Sometimes that tool in the lightning needs his ass kicked and theres no time to open the bottle behind the seat)
DYNO TUNE! PRICELESS!!!!
i dont know anyone more knowledgeable than justin. He is the fastest you know,
Also if your ever planning on running a 2 stage or a 150+ shot. A 3 gallon tank of 118 octane with switches, pumps, filters, and plumbing cost around $250
