just wondering i was thinking of spraying my vert and i was curious how a rotary reacts to nitrous?? if anyone on here has done it let me know what setup your running, im looking for idears thanks

i just scoped out a nx wet kit.. but i dunno the difference between wet or dry

 

Wet mixes fuel and nitrous. A dry system adds more fuel via the injectors. Its then controlled by a aftermarket ECU or regulator.

 

i see. so i will have to buy an ecu if i wanna spray?

 

If you ask that kinda question, you should read up on it and become somewhat familiar.

http://www.1300cc.com has some information.

 

ok i read that, it says our injectors r bein pushed as far as they can already,, and that i need to change my fuel pump and reg?? cant i just get bigger injectors and get a chip for the ecu or sumthing,, it sounds noob i know but i was just curious

 

uh.. right..

If your going Nitrous, I'd reccomend a 50, or max 75 shot. Use a wet kit (injects fuel with the nitrous via is own injector, since like you siad our injectors are maxed). Anything above that and you'll have to upgrade your fuel pump and regulator to supply enough. Check out Summit Racing they've got a lottt of nitrous kits.

 

Essentials:

1. Fuel Pump
2. Wet Nitrous Kit

Don't assume the stock pump will support a 50-75 shot. Also, there doesn't seem to be a huge price difference between the Dry and Wet kits. If your gonna spend $500+ on a new kit, get the wet.

 

i run a wet 50 and 75 shot on my s5 n/a. I just used a walbaro 255 and spliced into the return line on the secondary fuel rail to supply fuel to the solenoid. Also sent my injectors off to cruzinperformance for cleaning. So far nothin bad has happened, and i only use it occasionaly at the track

 

Er, for the best tuning use a fuel pressure regulator and make SURE you have an upgraded fuel pump. Nitrous need fuel to run properly.

Don't forget little things like purge too, keep them lines clear .

 

Do a search for "nitrous" and "Scathcart". There are some REALLY good threads by him.

If I may ask, why?

 

Lot of bang for little buck.

 

DO NOT splice the fuel feed line into the return line on the stock system.
The return line is under almost no pressure... and as the revs go up, fuel supplied to it decreases dramatically.

This will blow your engine instantly.

 

i think you should think of nitrous just like a turbo, after all they do the same thing to the engine (add air), well if you add air you have to add fuel to avoid a lean mixture (lack of fuel) which can cause detonation and **** your engine up. that's why people suggest a fuel pump, and the injectors won't need to be bigger if you run a wet system because it has it's own fuel injector, i think you can modify the banjo bolt that connects to the end of the fuel rail to have a feed for the wet system injector, or maybe you replace the pulsation damper with a banjo bolt. idk, but watch out for detonation.

 

Because the bottle rocks?

 

But so does a nicely tuned rotary.

 

But not as much as a nicely tuned rotary WITH nitrous!

 

Get a turbo.. Its like nitrous without ever having to fill a bottle...

 

turbo

 

ok sumone make a list of what il need for a good nitrous setup, this happening b4 new years, and im thinking of upgrading my ignition due to a slight miss between 500 and 2500 rpm's if u hold it steady

 

That's probbaly your TPS...

 

oh ok FSM for that i was still thinking should i upgrade the ign as well as the fuel system, i need a good steady spark to go with the fuel and air increase

 

Yes, I love Nitrous.
