I like to think that I can run nitrous on anything with an or on it, but I've been asked to help with an install on an M3 and I've honestly never touched a BMW before. Does anyone know of any reason why nitrous wouldn't not work on this engine? I've already checked the compression ratio and it should be fine with premium fuel.

 

you can spray on pretty much anything as long as you got the fuel...

 

I guess go ahead and spray it...Just seems a little stupid to me if the person has the money and can afford a 02 M3 seems like the could afford a better power adder than nitrious. Personally I wouldnt spend that much money on a car then melt the pistons

 

I'd be very weary about spraying on an 02 ///M3. They have been having quite a few problems with those motors as of late. A lot of people, as in, far more than usual...who have been driving them the way that they were supposedly meant to be driven, have been blowing their motors left and right.

 

no kidding

look at this:

Topic: Another M3 engine gone ('02 SMGII)

"My '02 M3C had about 2000 miles on it when I took it to Texas World Speedway for a dealer driving clinic. On my 3rd (warm-up) lap I heard a loud tapping so I pitted ASAP. As soon as the dealer guy heard the sound we called the flatbed.
The car sits at the dealer today with an engine on order. They are waiting for some tools to be delivered to do a complete diagnosis (my service advisor stated "yours is the first engine that hasn't come apart, so BMW wants to study it carefully.")"

they even have engine failure posting guidelines on that forum!

 

seeing as how the engines in the damn things are blowing up on their own, id hold off till warrenty expires.

 

I've read about these motors having problems also. There was an article or an Ad on EuroTuner about a SC for the E46 (M3). Much safer than NOS I think.

 

I'll talk to the guy tonight. I have a strong feeling that the guy didn't know this when he bought the car last saturday.

 

BMW... the ultimate expensive experience

 

Spraying on a new M3 motor is pretty foolish.

In the worst case scenario, you blow it up. BMW isn't dumb. You are gonna have to pay out of your pocket for a new motor. I can't imagine a new M3 longblock going for less than $12k.

 

A 50 shot on a well built I6 w/3+Liters of displacement won't blow. We're running 50 shots all day on 1.6L I4s without side effects. The whole idea of these motors blowing on their own is what scares me. I don't want to get blamed for a bad install b/c BMW can't slap together a decent block.

 

I have a friend here in town that is a tech at the BMW dealership here. He says they have had at least 5 cars come in with broken camshafts. BMW tried to design a cam that could rev out to 8000 rpm and apparently failed.

 

I'd stick with a Dinan/Mosselman supercharger kit.. atleast they come with a reprogrammed chip and FPR etc.. more of a "complete" setup.. and something that would be much more reliable on a day-to-day basis than NOS

 

So the answer is an overwhelming NO...lol. I would advise your buddy NOT to go ahead with the install. Hell, I'd advise him to return the damn car if he enjoys driving them like they are supposed to be driven. GOD I would be PISSED if I were in his shoes.

 

The motor is so on edge that spraying will probably blow it up. Without spending some serious money, your friend will have to deal with getting owned by Hondas. Sorry

 

who would spray an M3 anyhow u got the money for that u have the money for better mods than Nitrous, Plus it is a nasty car as it is

 

I wouldn't spray it because the main and/or rod bearings are probably failing already... why help it along

hehe

 

Complete? Yes Dinan is nice stuff, but a wet kit is also very complete save the purge kit. I'll be advising him not to touch a thing on the car until he is sure that his engine isn't a dud like many of the others.

 

yea how about 55,000 reasons ($) why not to.

 

man throw some deep dish 19s no there and go jock some girls or at least that is what i would do if i had 2002 m3.

 

I know a few that has it on some M3´s in sweden but the clutch gave up.
Check with some european forums.

 

$45k

 

just watch with bimmers man , they are tricky, them dam germans. . . i had one, and I was scared to mess with ti much , they are really bass ackwards.

 

thanks for the info. the M3 laughin is talking about is my friends. laughin is damn good with nitro installs (from what ive heard). My buddy was toying w/ the idea and would do it just for ***** and grins. the 3 is the daily driver/winter beater while i rebuild his vr4. i'll pass this info along to him and see what he thinks.
