Here a few things that you will HAVE to do if you plan on running N2O:

You will have to pull back your timing,

You will have to run premium unleaded.

DO NOT spray below 3000RPM, with a wet kit spray u fuel into your intake manifold at too low a rpm the velocity of air is not traveling fast enough to pull the fuel in too so it will puddle in your intake manifold and explode

I would HIGHLY recommend buying a NX TPS switch, it only opens the solenoids at wide open throttle so u make sure you are not running lean. I also hooked up a MSD rpm acivated window switch so the solenoids will only open between 3000-7000rpm's. The MSD sends out a 12V- ground signal out in the certain rpm range. The tps requires a 12V+ and 12V- to operate so I hooked the output of the MSD to the ground of the TPS so even if I am at wide open throttle I cannot spray until the MSD box reads between 3000-7000rpm, this is a failsafe way to ensure safety for u and your motor.

Have your car dyno tuned to ensure your air/fuel ratio is within an acceptable range

Buy colder spark plugs

I have run it for years on Honda’s, and they aren't built nearly as stout as the 3.3 in our trucks.
