2000 BMW M Roadster (Supercharged)

The time has come to sell my beloved M Roadster. I’m the second owner (bought it in 2004 with 53k on the odometer.) As seen below, it’s clear I had gotten the mod bug big time! My only reason for selling is I rarely drive her anymore-- all my focus is on the 308. It’ll hurt to take such a hit considering the money I’ve spent over the years, but it’ll make me happy if this car can go to a like minded enthusiast that’d appreciate everything done to it (at least that’s what I keep telling myself.)
The car has been meticulously maintained and I have all records. I’ve always been on top with changing all fluids/ inspections at their respective intervals. Admittedly, I’ve probably gone overboard over the years with how many times I’ve changed out the water pump and other items known to be weaker points on this car.

Cons:
• Few door dings, paint chips due to age/ mileage
• Light scratches in RR bumper panel
• Rear plastic window is a bit hazy. It was replaced in 2006, I shortly bought a hardtop which is on it 99% of the time, so window began to haze again with age
• Power windows sound “haunted” aka creak when using
• Some oil residue around s/c inlet, due to ccv setup (needs to be wiped up time to time.)
• Because of the large heat exchanger mounted in the front, I'm not able to fit the lower splash guard under the engine (hasn't been an issue as I don't drive her in the rain.)


Here’s the abbreviated modification history on this car. I originally had the car supercharged with a standard Dinan kit in 2006 by Avus Autosport in Glendale. Over time, I began to obsess over having more power--it's human nature, what can you do. The Dinan kit is a nice setup, but there wasn’t much room for upgrades, so I began to switch over to an RMS setup (main reason was to be able to fit an aftercooler in the engine to safely up the boost.) The car has a Nick G tune (Technique Tuning, Inc. ) which is tried and true and actually very conservative for where the car is currently at. I say this because a couple years ago I had RMS do a headgasket job and at the same time install new pistons and lower the compression.
The s/c pulley was swapped out to compensate for the lower compression. My plan at the time was to eventually retune as it’s a tad rich, but I never did as it ‘s still plenty fast. I only drive the car a few times a month and have come to the realization that it’s time to sell. This is a great opportunity for someone to step in and take over with the modifications for a very fast car, especially considering the new pistons and compression has a plenty of untapped potential. I stopped counting the receipts around $30k so someone’s definitely going to get a deal!

I did a couple times throughout the years. It's been around 350rwhp, hence the potential for more is there with a new tune.

 

158...huh?

A little over 3000lbs.

 

Bumping this. I didn't really try that hard the first time to get the word out, car has more sentimental value than I realized! At any rate, I'm moving forward with posting this on various sites... just really want this to go to someone that will truly appreciate all of the work that went into it.

Including an updated shot of the interior, I relocated the boost gauge to where I originally had it for a cleaner, factory look. And, I finally got the car dynoed... 372rwhp (roughly 430hp crank.) She's fast and well sorted!

Its also worth noting that the shop I originally took it to was trying to get me to retune it. Turns out my afr's are good! Here's the dyno chart. The first run was aborted because the belt was slipping (which was replaced.)
