Good place to start for nitrous on the S54: http://www.m3forum.net/m3forum/showthread.php?t=208229

The NX kit can be purchased through CPI (asianjedi is a good guy to talk to about it as he was one of the first to run it - he posted in the thread linked above).

Boris (boki) has been running a NX dp kit for a while now - he has a lot of good info in there as well.

Read it all....lots of good stuff in there. Remember that a single fogger w/ the M3 inline six will need lots of dyno tuning to get all cylinders equal amounts of fuel and nitrous. And it will be the least efficient of all setups. There are a lot of different setups out there (dp, single fogger, WON 6 pulsoid dp, etc.). Really depends on how much you want to spend and how much risk you are willing to take with your $10k engine. As a side note, I have a WON kit that I am installing right now and spent a little more to keep things as safe as possible.

Total cost for the system can be anywhere from $750 (no frills single fogger) all the way up to about $5,000 (WON six pulsoid dp - see jtrejo in the thread above).

Stock software *should* work but I would call Active Auto (ask for Barry - he did all of the coding for the m5/m6 ASR NOS setups that can be seen on m5board.com and all of the Florida nitrous m3s) and tell him what you want to do. He will have some additional info that would probably help you out (concerns the e46 m3 computer, cylinder misfires and what the computer will do in response).

My best advice would be do LOTS of research and, if in doubt, spend a little extra so that you make it as safe as possible (just my .02).

Some other sites to look at:
e46psi.com (older posts but some good info if you look hard enough)
noswizard.com forum http://forum.nitrous-advice.org (LOTS of good info here - make sure you look at the "BMW M3 DP Install" thread under advanced nitrous)

Good luck,
Mike

should maybe get like, a 50 shot instead of 100, it'd be only just in case anyway, the m3's fast enough as it is.

is that including install? if that including install you can get a decent kit. if its not including install then you can get a prety good complete kit.

for 1100 you could get N/X nitrous kit, FJO nitrous tuner, and remote bottle opener all installed.

without labor, everything i listed with a bottle heater and maybe a purge kit also which would be a complete and prety damn good kit.

the only way you could get something beter is if you go direct port (tap each throttle) which would cost about 1800 installed without all the goodies ie: FJO, remote bottle opener, purge, bottle heater...

Also dont forget, get colder spark plugs installed or your gona melt the stock ones when you spray. one step colder should do the trick.

ofcourse everything depends on what your goals are with the car and howmuch of a shot your looking to do. if you plan on going over 100 shot your gona need to get tuned which could cost a prety penny unless you wait for shark edit to come out haha.

if you have any other questions, there are a few guys that know a hell of a lot more about nitrous then I do on e46fanatics. I just touched the tip of the iceberg.
good luck

haha there are tons of subys and evos here also. Just do a google search and look for a nitrous shop. there should be a few in your area. if no luck then call a few performance shops and ask them for refrences.
if you spent 2000 installed you could get a direct port system installed with the fjo tuner and maybe even a remote bottle opener. direct port is the safest way to go because it sprays an even ammount of nitrous into each throttle body which allows you to spray even more without tuning (about 125 or so)
if you have any further questions feel free to shoot me a pm.

hey u guys seem to no what ur talking about on here so ill give u a real "problem" to think about.

I have a 2005 325xi with a complete supercharger kit from activeauto with a cold air intake and a brand new exhaust from supersprint consisting of connecting pipes, resonator, and muffler plus other mods like suspension etc. I want to put nitrous in my car but its not manual, i am stuck with the steptronic tranny, and i have been told that the awd of the xi is sometimes a problem with nitrous? also, i dont want to damage my engine. i probably wont do any more than a 100 shot but also i have heard that over time nitrous can seriously screw up your engine which i cant really have. Any suggestions, ideas, advice?

nitrous is accually much safer to use on an auto because you dont have to worry about bouncing off the rev limiter and spraying at the same time (if your not in tiptronic) since your supercharged already I wouldnt run more than a 50 shot without a tune to be safe and if your gona spray, stay in auto mode

hey im probably gonna get it tuned after, but when u say if ur not in tiptronic, i can drive my car 3 ways, i can have it in the regular drive, i can shift it left into the sport mode but not manually shift (this is the way i drive it 99% of the time) and then i can move it left and shift manually. would i still be alright if im driving it in the sport mode but not shifting manually as this is really still an auto mode? And if i am in tiptronic would u still recommend running the nitrous as long as im careful about my shift points and how i use it? also, instead of direct port or something that is directly into the engine i think, i was told about a fogger kit that would either spray straight into the intercooler or into the pipe between the intercooler and the engine? supposedly this is less powerful and i would only get like 35 from a 50 shot but that its safer for the engine? thanks

it all depends on what kind of power your looking for with nitrous. there are sooomany people that do the spray on the intercooler which is a prety good idea but if your looking to get more power and your planning on getting tuned then you could go up to a 125 shot with a single nozzle sprayer. by fogger do you mean dry kit? I wouldnt go with a dry kit(just sprays nitrous and injectors spray extra fuel to compinsate). its much too complicated and much more dangerous because you have no idea how hard your injectors are working and if the injectors are already at its capacity then your gona spray toomuch nitrous. as long as you get a wet single nozzle kit (mixes fuel and nitrous) or an intercooler sprayer and your planning on tuning then your gona have a lot of fun with your car keep us updated.

E46Arash, thanks a lot for the feedback, seems a wet single nozzle kit or an intercooler sprayer is the way to go. but what is the difference between them? really just where does the wet nozzle kit spray into? also wat do u think about the size of the shot and possible company to use, Nos, NX, Venom, Zex, etc. sorry i keep asking so many questions lol im just totally new to nitrous
