NX express Hitman nitrous system. Good or Bad??!!

ok people what i want to know is if this kit is a good kit with good quality peices. This will be my first time installing and using a nitrous system and I have read that its for the N20 impaired but is it good quality. Is it better than the Holley NOS Super powershot brand? Any help will be appreciated.

The Hitman is NX entry level nitrous kit, compared to other brands entry level kits the hitman is far better in quality than the rest. This will be a great kit for you if its your first nitrous install, simple and straitforward.

Well I just ordered one about 15 minutes ago so I cant wait for it it to get here. I am gonna also get a fuel cutoff safety switch or something like that, and a aircraft style trigger so that when i have it too the floor I can activate it myself. Isnt that what that switch allows you to do?

Manual switch is about the worst thing you can do in my opion, to much room for error. Get a switch to arm the system and then get a micro switch that activates it at full throttle. Thats about the easiest,cheapest way to make it idiot proof.

Anyway welcome to the wonderful world of nitrous,now get ready to buy all the acc. your gonna need for it.

Yep that kit will do nicely. That with the hitman kit will have you a very nice entry level nirous setup. You will be pleased with the NX parts and performance.

Ok I just recieved my kit today. Well its looks good and all but I dont see how I am supposed to activate this kit. I dont have a WOT switch in the kit and I was looking in the GENX 2 kit and didnt notice on in there either??? Am I supposed to buy that and an arming switch seperately???

what no nitrous company ever tells you is that you dont get EVERYTHING in the kit.... they usually leave out saftey devices in the name of lower cost.


im **** about nitrous. i like my motor too much to blow it up...
if it was me, i would get a nitrous mastermind... it has the fuel switch, revlimiter that shuts the nitrous off first, pulls timing, and is a window switch. but you do need a aftermarket ignition to use it (like MSD-6A or similar.)


at the very least, get a window switch, WOT switch, and a good arming switch.

A window switch turns on between a pair of engine speeds which you can usually program in some way.

oh ok. does anyone have any pics of a nitrous system like this one? I was reading my instructions and it said that I need an adjustable fuel pressure regulater for the nitrous system and it says do not connect the N2O systme regulator through the carb regulator. But I ran across this little NOTE:Hitman systems are designed to operate with stock mechanical fuel pumps without a regulator. Does that mean I dont need a regulator for the nitrous?? I know I should need one for the carb. Am I correct on that?
