    you drive an e30, its not an e92 zomg m3. get over the whole i drive a bmw, i have a euro sports car mentality. its a sohc 6 cylinder, pump a fuck ton of nitrous into it. blow it up and swap it out for 200 bucks.

    rinse and repeat.
    thank you! you beat me to it!
    if you run a wet system you should
    be fine. remember that you are not goint to be putting a 100hp shot on a stock motor, but if you use the 25% hp rule you should be fine as long as your motor is not worn out.

    i have run as much as a 50hp shot on several A-2 VWs (stock motors) without any issues. it makes for a fun car, just don't be a dumb ass with it. before you go doing it make sure the motor is in decent shape and check the price of refilling the bottles. refill pricing has taken a decent jump in the last few years.

    one issues i did run into with the single fogger kit was that:
    A. when you put it through the intake boot like they say to in the instructions, it will try to push itself out of the boot after a few shots from the pressure at the nozzel.

    B. it tends to freeze teh throttle shaft so that it will not close all the way when you let off after using it. that just leads to a momentary high idle until it thaws out.

    i solved both of these by machining a 1/2" plate to go inbetween the intake manifold and the throttle body, then tapping it for the fogger nozzle. that gives it a solid mounting point and puts it behind the throttle plate so it can't freeze it.

        Could nitrous be plumbed into an m20 using the 325e cold start valve setup, or at least just removing the cold start stuff, and install the nos injector through it?

          BimmerJoe is hilarious... fully built engine, yet he has only replaced the rockers. Impressive... I'd love to see your built NAWZD-out M20 lose to a stock S50 swap.

              you could, but, there is a strong chance that you will not get even feeding to all cyl. most likely the centers will get most of it and the outers will starve and run lean possabily causing damage depending on how much of a shot you are using. remember that you are injecting gas (NO2) AND petrol . the petrol will be what does not feed evenly to all cylinders and the NO2 alone will make it lean.

                  ok well I removed it from my parts car now, and the system is a wet system but I'm still unclear as to how big of a shot the parts car was set up for? There isn't anything on the nozzle that says what it is. So what dictates the shot size?

                      there should be jets or "pills" in the fogger nozzle indicating the HP "shot" you will have to unscrew the end if the foffer that goes in the intake to see what size they are. they usually go in a 5 hp incriment ie 25, 30 , 35, etc.

                        Make sure you don't let the diamondplate floorpan fall out while frying piston rings.

                          Why all the hate?

                          A properly set up system should do no damage to the motor. It's not different then supercharging/turboing; all you are is getting more air into the engine.

                          A wet system is the way to go, so you are lucky your part's car was set up with one. This helps avoid a sudden lean mixture, burning valves and putting holes in your pistons.

                          I actually just recently discovered a practical use for nitrous. My daily is a MK2 Jetta, bone stock and it is as slow as balls. I have no interest in doing anything to the car as it is boring as fuck. While driving over the pass the other weekend, I realized it would be nice to have an extra 50 HP to use for passing. Nitrous is the answer. :D Simple modification that is actually useful!
