BMW 323i nitrous FINALLY!!!

After a month, finally got to finish my nitrous project.
It goes to all of you who talked bs on my last nitrous post.
Here is the parts list:

-Zex wet kit 55 to 75 shot
-AEM fuel pressure regulator
-MSD rpm switch.
-MSD adjustable rpm module (3000 to 5800 rpm)
-MSD rpm module 5600 rpm
-zex spark plugs
-zex purge kit
-AEM wideband failsafe (not installed yet)

As of now im running a 30 shot. Using a .027 nitrous .015 on fuel. Its a noticeable +30hp.
Will get back to you when i take it to the dyno with the afr gauge installed and a progressive controller.

Here are some pics

agreed, i am smart.

you're doing it wrong. the wideband is your lifeline to know what's going on in there. tuning 101. start a little rich and lean it out. you slapped this kit on and tested it out essentially blind. way to go. you're lucky it didn't pop already. we all know you can make copious, easy horsepower with nitrous. if there was no downside risk, it would be incredibly common.

OP, congrats on what you've accomplished so far.

You should ask the Mods to move this thread to the F/I forum, you'll get little to no BS in the appropriate sub forum.


PM on the way.

Man. Awesome job. I was looking to add a 50 shot myself.
Did you do it yourself, or did you have it installed?

Is that a stock m52?

Also, why is there a black fire extinguisher behind your seat?

Poor car. I would sell the BMW and buy a Camaro or Mustang if this is how you mod your cars. Forcing a poor 323 to literally kill itself (wait and see, I will be right) just so you can pull on a couple 330i's or a few bone stock mustangs with bad drivers is asinine. You do know your intake is made of plastic and will explode extremely easily, right? If you like learning hard lessons from first hand experience, party on bro! I give you no more than 15-20 pulls with a 50 shot before you start seeing problems with your engine. This thread makes me laugh and cry at the same time.

this. and he thinks we are just being jerks. nitrous has its place and it is not on a bone stock M52tu.

the fact that he did a few pulls without the wideband even installed tells me he isn't going about this the right way. If you have any chance of keeping the engine from grenading on you, you need to keep track of the AFR constantly. If i were you, i would not have done any pulls that triggered the nitrous until i was actually ON the dyno with both the wideband installed AND the tailpipe sniffer of the dyno setup so you can accurately and safely hone in your wet nitrous shot. given the difficulty in "tuning" these engines as far as timing and trims are concerned, i am not sure you will ever have a truly clean or safe setup. this looks a bit hacked together. i also don't like the nitrous bottle on the floor of the rear seat.

personally, i would have used this time and money towards a true FI system like a supercharger, which will make more power throughout the rev range and provide more reliability. it is worth the extra cost if you want real power in these cars, and i can't see that your wet Zex setup is that cheap either.

I understand guys. I did two pulls using a .017 for nitrous and .012 on fuel. This was just to test the kit. I now it was crazy to run it without the afr gauge.

Im waiting for my tuner to call me to get the kit set up right. By the way my goal is only a 30 shot. Im not a street racers is just something to have and go to the track a couple of times in the summer.
