Well i finally decided to try the nitrous scene out and bought a kit (nitrous outlet) from a really good friend of mine .. I have been doing a lot of reading and research and came to the conclusion that a 75 shot would be ok to start off with until i get a new clutch and engine management !! Luckily i have a close friend that has been running it in his altima SER for a couple years now and he's kind like my crew chief lol !
Safety wise for a 75shot i was thinking/going to; run 1 step colder plugs and there's a Dynotune 2 step window switch / WOT that looks like a good must have ..

A few questions i had were, is it necessary to go ahead and upgrade my fuel system ? Also i was looking at the Dynotune lean cut off switch and was curious if there's something else out there better for the money ? Lastly would it be better to get a plenum spacer ?

Right now i have Nismo Intake,headers, and exhaust and my car is an 04 6spd touring .. any questions feel free to ask !! i hope to get it installed within the next few weeks and get it on the dyno, i just wanna make sure i take my time and get it done right minus tuning and i'll be sure to take pics of the install :-)

Thanx again

 

you won't need to upgrade your fuel system. Don't forget a bottle heater and pressure gauge.

 

ohh yea .. and purge :-) i'll make sure i add those to my list

 

You can use the dynotune lean shutdown switch in narrowband mode since the "widebands" didn't get put in until 04.5 models.

 

oh ok sweet ! do you think it would be a good investment, or is there something else out there better ??

 

Can someone explain what the wideband thing is, for the 2004.5 models? Mine is that model...

 

From what I have read, it is a very sound investment to get just to make the nitrous safer, especially for $100. You can run it in narrowband mode, but it is more accurate if you do wideband, which would mean getting an aftermarket wideband and finding a way to tap your cats, you can either drill a bung or buy hfc which have them already. I plan on getting the innovative and berks hfc to get it running wideband.


If you have an 04.5, you have factory widebands which register at 0-2v, which means you cannot use the dynotune a/f switch, since it can only read either in narrowband mode 0-1v, or wideband mode 0-5v, so it will not work with 04.5 and up which all have factory widebands.

 

Thanx for the input guys !! what do you guys think about a fuel pump ?? unnecessary ?? and if it is a good thing to have .. do i need a fuel pressure regulator for a walbro 255 !?
