The entire kit weighed 36 lbs, but that included the packaging. The intercooler had some weight to it actually. Here is a link to the kit: http://forums.bimmerforums.com/forum/showthread.php?t=731055 Scroll down and you will see pics of the complete kit. I'll leave the a/c in for now. Comes in handy on rainy days when you are trying to drive out the humidity from inside the car. Eventually I probably will gut the car, but for now it is my daily driver. Thanks for the feedback.

The blower itself is the only thing that really adds weight. I'd live your A/C in place unless you're going to gut the entire car. The power you're adding will far and away offset the slight gain in weight.

If I remember correctly, there was at least one post on the forums that said this oil pump nut behavior was highly correlated to using lightweight pulleys...sounds somewhat reasonable to me, though I don't have experience with the vibration calculations that might lead to this behavior. Haven't done differential equations in 6 years...and I hope I don't have to do them again any time soon.

It's highly correlated to spinning the engine backwards (get the clutch in when you spin!). It's also highly correlated to E36s and E46s.

Any car that has seen, or will see, track time, should have this addressed IMO. In some cases it may just be a preventative/peace-of-mind thing - the oil pump nut was tight on the M3 after ~10,000 track miles when we went in and secured it. Jim Bassett - is it necessary to say "BTDT, have the rebuild bill to prove it"?...didn't think so :-)

Date: Wed, 20 Jun 2007 22:45:36 -0700 From: Scott M <smlists@pacbell.net> Subject: Re: [E36M3] here we go again... True, but at least they do still make a ~3100lb true sports car coupe in the Z4-M. Just no back seat. Can't have both. Dammit anyway. Even the new Evo is growing in features, luxury and heft - up to 3500lbs from the previous car around 3300. So even in the more hard-core enthusiast market, the car companies are realizing they can sell more cars with a more luxury slant. I agree it is sad. Still, the E90 M3 in 4-door version will be one heck of a sedan, and will be some 300-400lbs lighter than it's nearest competition the S4/ RS4, not to mention far better weight distribution. It won't be quite as tossable as the E36, but it will have great power, awesome torque, and still should have magical precision, steering feel, balance that go along with a BMW M-car. And it is quite a bit lighter and with a shorter wheelbase than a E39 M5 with basically same engine, so as a sedan it is going to rock. In fact, even compared with a 911 Turbo it should have comparable performance - those are 3500lbs now too and with similar thrust.

The oilpump nut on my 02 330i came off during a spin at the track, I didn't get the clutch pedal in soon enough and stalled the engine. The symptoms were a complete and immediate loss of oil pressure, so I am pretty sure that's what did it. What I am not sure about is what the mechanical reason is that the nut comes off. Even if the engine and therefore oilpump "spin backwards" which I am pretty sure did not happen in my case, the oilpump drive shaft is a splined shaft which prevents the oilpump gear from spinning on the shaft and unscrewing the nut. It's hard to imagine that a tiny little nut with almost no mass could effectively be unscrewed by stopping it's rotation quickly (stalling the car as happened in my case) or even spinning the engine backwards especially since it isn't like it'd be going backwards very quickly. My personal theory is that these nuts loosen up very soon after the cars leave the factory and most of us who haven't Locktited/wired the nut are driving a ticking time bomb. By the time we spin or overrev at the track that oilpump nut is just hanging on by a thread or two and the sudden decrease in engine speed is enough to just spin it off, whereas if the nut was tight there would be no problem at all. Anyway, just my $.02. Regards Jamie Howton 06 M Roadster 04 645Ci SMG 95 M3
