Alpina Roadster S Supercharged

[Femme]

Hi guys, I would like to introduce you to my supercharged Alpina Roadster S. Some of you will have read about it in this thread. I have now documented all modifications on the car and I have also released a video we shot in Norway afther picking up the car at ESS Tuning.

My car is a 2004 Alpina Roadster S which comes with improved aerodynamics, some nice interior refinements and a 300HP 3346cc inline six based on the S52B32 engine. I bought the car in April 2006, then started modding it three years ago.





Soon thereafter things got out of hand and at some point my car looked like this:



Fortunately we managed to put all the bits and pieces back together in summer 2008 and then I had this:





Which was nice but still a bit down on power so contacted Asbjorn at ESS Tuning in Norway. I drove my car up there, took the flight back to Amsterdam and waited six weeks. The result was the world's first supercharged Alpina Roadster S, now sporting no less than 445 ponies.









Back at home I finished it off with Tekarbon angel eyes and black painted headlight housings and an Ultimate Pedals brushed aluminum pedal set.

The complete list of modifications:

An instant classic. Saying well done would be a terrible understatement.

Quick questions. How much did re-trimming those Pole Positions cost you? And did you use an aftermarket seat heating setup? I am looking to pick up a pair of Pole Positions and wouldn't mind saving money by going with the cloth option and getting them reupholstered. I'd go with a leatherette-type vinyl or leather.

[Twisted Six]

Love it all. Thats impressive HP from stock to say the least as well.

[misterawa]

OMG , I'm speechless.

I've seen pics before here and on Z4-forum, but OMG...STUNNING!

I'm pretty sure reupholstering the seats is more expensive than buying leather upholstered seats right away. We ordered a new pair of seat heating pads at the BMW dealer. You can lookup the part number on realoem.com.

The Recaro Pole Positions are perfect if they fit your body size. I'm in love with these seats .

Wow that is a lot of work but great results, car doesn't look wild to the point of ricey but definitely shows theres more under the hood then the stock 3.0. Any videos of this beast?

Thanks. I may end up getting the velour seats and just reupholstering the bolsters since those are the parts that would wear out first.

And what about the airbag sensor/light/mat on the passenger seat? How did you address that issue? I've read that you can simply use the occupancy mat out of an E46 M3 which goes for around $100. I've also seen people using various black boxes or emulators to trick the sensor but that doesn't really appeal to me all that much.

Alpina. It's standard equipment on the Roadster S and can be ordered separately in combination with the Alpina front spoiler lip.
