I just bought a nitrous express kit but didnt get it yet and I was wondering what to expect when it comes time to install it on my 94 LS. Can I install it myself or should I get a shop to do it for me??? (how much of a pain in the *** is it).

And one more thing after I install it, when it comes time to get my car inspected will the nitrous interfere???

 

big difference between installing it and tuning it. a 5 year old could do most of the install, it's the jets and spark plug and timing you will have to play with... as well as fuel pressure if you run a bigger shot than about 55. I've found it's best to get the nozzle welded to your intake tubing just to be safe. The threads will get it in there snug, but not snug enough to be safe and long-term.

You have NX so it is a wet kit. You want the the nozzle less than about 8" from the throttle body and so it has a straight shot in for the fuel. It's not difficult to install a nitrous kit at all. NX says you can run stock ignition timing with their kits due to the way the nozzle atomizes the mixture. You'll need one step colder NGK copper plugs, gapped to .030". It's a good idea to bump up your fuel pressure a few psi, just to be on the safe side. Make a pass, and check your plugs to see how it is running.

 

And about how long does it take to do the install????

 

Couple hours depending on how crazy you get trying to hide everything. But for a basic install, a couple hours.

 

And about the inspection part of it???

 

However long it takes you to get the right a/f mixture. Could take a while.

 

About how much does it cost to get a 15lb bottle filled???

And since youve had your nitrous are you really happy with it or do you sometimes wish you never bought it???

And how often do you use it?

 

mine took me a full day , but i have gotten maby compliments on the install by tuners. so its worth it to take your time .
i just have to hide tom moe wiring in the engine bay. i have no room to get my damn hands in there.
you will love it , trust me . esp with the wet. i wanst impressed with my dry kit , so i upgraded.

 

Right now I have AEM intake DC sports 4-2-1 and random tech high flow cat and tanabe RM exhaust, Once I install my nitrous express what kind of quarter mil times can I expect???

 

i know someone w/ a 97 ls w/80 shot nitrous and did mid to low 12's. stock internals just i/h/e and 8.5 lb flywheel

 

That had to be a swap into a gutted hatch. In an integra, an LS on 80 shot will do high 13's

 

should get a fuel pump along with it.

 

Must have a death wish putting a 80 shot to a 8.5 lb flywheel. I'd hate to see it burst from that stress. Most juiced engines won't run a flywheel that light. Make sure your buddy gets a scattershield if he doens't have one already... i'd hate to the person in the passenger seat when that flywheel shatters and comes through the fire-wall.

Don't need a fuel pump/ignition until over an 80 shot

 

wow , thats an exagerated time if i ever heard one.
that car musta weighed like 1600lbs to pull that time

Wow, it can come through the fire-wall?

 

yeah... if a flywheel shatters they shred through the tranny casing and pieces fly everywhere.... including to the firewall and through it. Think about how many thousand of RPM's that flywheel is spinning at and how much momentum the pieces would have. Not safe... that's why scattershields are required for many race classes.
