E46 Dinan Supercharger for BMW M3 E46

Hey

Selling my dinan stage 1 supercharger kit for the BMW m3. This kit is the low boost kit that makes 423hp. This is perfect for daily driven cars or high mileage cars due to low boost and increased reliability. I bought this kit used from someone who had a dinan car and parted it. I was going to install on my car but now going a different route with the car. Supercharger kit is in good shape, supercharger spins fine without any issues. Kit is complete but does not come with tune. A tune should be easy to get since it's a vortech based kit like vf or ess. Frank Smith should even be able to provide a tune if needed. I am looking for $3,500 for the kit. Email me at bmwm3s50@aol.com with any questions.

Pic Request: alcantara HL and pillars with beige carpet and leather

So I'm in the process of updating some things on my e39. The car used to belong to my grand father and he smoked like a chimney. I'm going to be scrubbing the hell out of the carpet and leather but I can only assume a lot of the smoke went up into the headliner. I was thinking of changing it out for the M5 alcantara headliner with matching pillars but I'm not sure exactly how that'll looks. If anyone has a picture of it I'd love to see it.

Also so if anyone car recommend a good odor absorber that would be great.

Under seat sensor wiring

Hello everyone,

I have a 1999 323i convertible that was really neglected by previous owners. It has 152K and seems to run fine. I have completely rebuilt the front end and have done the shocks, shock mounts and stabilizer bar links in the rear...RTAB's seem tight and fine. I have no maintenance history for the car and it is evident it was never really taken care of as far as the interior goes.

The front seats were in really poor condition and looked like they were never cleaned or conditioned. My interior color is the dove grey and after almost a year of searching I found an interior (front and back seats) in dove grey that was in really good condition that I could afford. The only difference I could see was that they came out of a right hand drive car and the passenger seat (driver's seat in USA) had the seat back release button on both sides instead of the driver's seat (passenger seat in USA). I really didn't care about that. Oh, the other difference was the replacement seats are sport seats (not from and M3) and mine are just regular.

I just put the interior in yesterday and found out that the sensors under the seat bottoms are not the same as the ones that were on my seats. It appears that the wiring and sensors are reversed between the euro and USA models. Not only that, but I think the euro seats are from an earlier model than mine.

I tried switching over the ones from my car but there is no place to mount on one of the seats.

Can anyone tell me exactly what the sensors are for on the USA models? I'm guessing something to do with the airbags?? My car has both driver and passenger airbags and the side airbags, as well.

I believe my airbag warning light is burned out because when I turn the key on before starting the car, I don't see any illuminated in it's self test mode. I drove the car yesterday and there is no airbag warning light on.

It appears as though the car harness plugs in my car are different than the receivers in the replacement seats. One of the male end plugs (and the only one that would fit in the switch on the replacement seat) with 3 wires going to it broke on the passenger side. Too much tension when seat was moved all the way back and the wires pulled out.

If this sensor is to detect a passenger and enable the airbag to work, is it possible to "jump" these wires to bypass the sensor switch so the airbag is enabled all the time?

What dangers are there driving without these sensors working?

I'm hoping one of you guys, or several of you, have extensive knowledge with the wiring in these E36's.

Many thanks in advance...

1998 Z3 Convertible won't open/close

I recently purchased a 98 Z3 in great shape...but this week the convertible motor started making a sound like it was "working really hard" to close the top. I don't know how else to explain it. It quickly deteriorated and now the motor struggles to close the top even about a foot... I have to get out and manually pull the top up to close it. And if I open it up, the top flops open really quickly - like it falls open.

I sure hope I'm explaining this clearly.

I'm assuming this is a problem with the convertible motor, maybe hydrolic fluid loss? I don't do a lot of work on my own cars but wanted to get input from you guys. Also, where exactly is the motor located? Assuming access to it would be through the trunk area? Is this something I could work on or is this something that needs a mechanic?

Thanks!

My first BMW

Ok guys, so my name's Chris and I'm a car addict.

Recently I just picked up a pretty molested alpine white 3 1994 325i. The car appeared to be in beautiful shape when i bought it with a few fixes apparently needed. After three weeks of owning it I'm starting to get a little nervous about it.

Here's some details. (pics soon to follow)

I got the car about three weeks ago with some known issues at the time. It had 179k.
I've put about 2000 miles on it, 1000 of spirited driving, as the car was used on the track fairly often.
The car is relatively rust free with a little bit of paint chipping and surface rust. (barely any)

Leaking valve cover gasket.
Broken hood system
poor headlight wiring
bad upstream o2 sensor Miscelaneous interior pieces missing. (center console, headliner sagging, rear-view mirror missing, etc.)

The interior is a 8/10 in sand color. All leather is tight and of original color, with no cracks or tears or blemishes anywhere. I don't know how this is possible for a car this old, but hey I'm not complaining.

The cars modifications are as follows...
headers, cat delete, (xpipe) and muffler. brand unknown.
Some intake thing that seems to be carbon fiber material at the filter
e3 spark plugs
bilstein struts, h&R springs
spacers, and 5x130 adapters with hollow body 18in. Porsche twists wearing hankook ventus evo212 k120s all around. All are brand new.
Polyurethane control arm bushings, upgraded control arms.
Bosch french headlights

also came with some refinished stock wheels and some projector headlights (with no ballasts)

Picked her up for the tune of $1850, i have plans to restore her to her original state while dailying and eventually build her into a heavily modified street/track car with rollcages and racing seats and all that fun stuff.

the bad...

The valve covers look previously (very poorly replaced) with some sort of gasket material seeping out the side (as well as oil too ofcourse)
As i started to go through the car in depth i started to notice a trend of general (for lack of better words) silliness. Messy wiring considering the headlights and engine bay, random little things the previous owner i guess attempted but never finished, and apparently "has no idea" or recollection of doing. I got the impression he was lying to me about alot of the car. Carfax told me the rest, as did common sense and basic mechanical understanding.

SO.

Since i've gotten the car, i've deleted the factory hood latching system and replaced it with some $10 autozone hoodpins till i can get my hands on something nicer, fixed the headlight wiring, replaced the spark plugs, (which were fried) oh yeah did i mention the valve cover has a bolt head broken off? So far, it hadn't been anything too serious so far, no leaks besides the VCGs, nothing BIG.

Until recently when i went to go replace the o2 sensor. I found that the PO had an o2 sensor installed where the headers collect, but the wire is gone. It's just gone. No sign of what could have happened to it. I'm assuming it was melted off by the heat of the headers. Which would be fine, but the weird thing is, now that i have a new o2 sensor, i can't find the port for the plug anywhere!

So today (around 5:30AM after work with a coworker) I went under the car with him and we did a diligent search, no upstream plug anywhere!

It gets weirder.. we thought about just simulating the o2 sensor, directly from the wiring of the ECU but the f*cking box is nowhere to be found! (its not in the engine bay where it's supposed to be)

So here I am thinking about what to do with this car, given it's trend of general "silliness" and what I'm scared I might uncover if I keep pressing on.

Otherwise, the car as far as I can tell, is in pristine condition for it's year and mileage, and I consider myself incredibly lucky to own it and plan on doing all that i can to push forward with it, and possibly even build it into a full blown track/street car. Because you know, a quick car is totally necessary on the streets.

Basically, i guess the point of this thread is to document the build process of this car, and get some help from people who have more experience with these cars, because I've fallen in love them, and how they drive, and would love to learn more about them. PLUS, I'll be damned if i drive something else. I plan on picking up a daily soon also (either an e30 or a honda) so i can work on this little princess without having to stress her out all the time.

Pictures soon to come, many pictures.

A big thank you in advance to anybody who can relate, share funny stories, provide helpful tips, or laugh at my pain.



Currently, the million dollar question right now is WHERE IN THE WORLD IS MY UPSTREAM O2 SENSOR PLUG DAMMIT?!

VCGs are next, along with painting the valve cover. I think.

Wheel fitment on a z3 1.9 (stance)

Hi all names Owen, I'm new to this forum and on the hunt for some information regarding aggressive wheel fitment to a 1.9 z3. I have searched the web for some info but not really having much look. I no this isn't every body's cuppa tea but if anybody has any pics they could share with there wheel specs stating size, offsets and widths it would be very helpful. Thanks again.
