yo guys im new to the forum... jus got my s2k and wanted to look into getting some nitrous while i save up for a supercharger... that being said i dont just want to slap on a nitrous kit like a dumbass and understand that ther is some tuning that should go along with it... what would that be. thanks in advance for any info

 

Buy a Nitrous Express Import EFI kit I've had the best luck with them. They are the only ones to give any kind of product warranty (Lifetime on cylinoids). My prelude had the 75hp pills in and made 68 hp to the ground additional. This was the kit in stock form. To make peak power and keep it more consistent youd need a bottle heater to keep up bottle pressure. To put nitrous on the safest way you should buy a GenX2 kit and an MSD Digital Window Switch. If you use the jetting provided by NX your fuel curve will be almost identical to stock. We tried changing the fuel jetting to get a better ratio but NX was almost perfect.(Yes on a dyno with a wideband.) The GenX2 kit comes with a Bottle heater/ Fuel Pressure Safety Swith/ Purge Kit /Dump Tube /someother goodies. The Window Switch will let you select the RPM range that you let the nitrous be active (in at 2200 out at 7800 or whatever you decide) this will keep you from spraying to early or into fuel cut.
Hope this helps

Oh It's way more fun than youd think. Like VTEC times 100

 

Moving this to the F.I. forum.

 

Definately go with NX, I'd go direct port if I had to do it all over again, it's only about $100 more than a basic kit. You should be okay as long as you stay within the reccomended jetting and make sure your fuel system is up to par. In addition to the kit itself you might want to consider colder spark plugs, upgraded fuel pump, fuel pressure safety switch, bottle warmer, window switch and something to knock back timing a few degrees as well if you're going to be spraying a larger (80+) shot. You're looking at at least a grand for a decent single stage setup. I'd advise that you just go ahead and get an AEM EMS to control activation and timiing as well as fine tune the A/F ratio on the bottle and off. It'll offset the window switch and timing controller and you can keep it when you go boost.

NX direct port
NX Gen X2 upgrade (FPSS, Guages, blow down tube, purge ect.)
AEM EMS
