Seeking CSL knowledge.

[///Max]

Hi. I've been a member for a short while but this is my first time posting. First let me start off by saying that I envy you guys a lot for being able to own a CSL. I live in the U.S. and as all of you all know we have no CSL's here. I've always wanting to own my own CSL and have even thought about moving to the UK to get into one.

Anyways, the reason why I am in need of your help is because I want to start a project to build my own "CSL" as close as I possibly can to the real one. What I would do is sell my 2003 Silver Gray M3 and buy a 2005-06 Silver Gray M3 CS. Im doing this because the CS has many similarities as the CSL so it would be a good platform to start from. Then after that, I basically want to buy these parts and install them. (Prices are approximate to how much we can get them here in the states.)

Exterior:
Front bumper: $3000
Boot lid: Already acquired from Craig!
Rear diffuser: $1000
Carbon fiber roof: $1611
Rear window: $1000
Grille emblems: $90
Wheels: $2500

Interior:
Front seats: $3500
Rear seats: $2000
Front door panels: $1300
Rear door panels: $850
Center console: $450
Door sills: $350

Performance:
Air box: $4500
Camshafts (both): $1500
Headers (both): $2200
Catalytic converter (both): $1850
X pipe: $850
Muffler: $1000

Everything is really straight bolt on and will have no issue with that, but there is one major problem. The hardest modification by far will be to get the CSL air box to work properly and have the engine run smooth. Many here in the states buy the air box and remove the flap because only BMW was the proper software to make it work properly. And after all that, many times the car has a rough idle even after a tune. One of my questions is, if I were to buy a CSL's ECU, with cams and air box already installed, would the car and air box run properly? If not, then how about getting a hold of a CSL's engine with ECU and air box ... would it work then? If anyone has a idea or solution, do tell.

This is one many questions I have in planning this project. I told a few of my friends, but they could care less about it. And it's not their fault, they just don't know or have never heard of this amazing car. I guess I just need to vent and let out what Im planning to people who know and appreciate the CSL.

If anyone has any information, or can pointe out something I may have missed, or have any knowledge of how to make this project a bit easier, please let me know. Im am always open to any information about the CSL. It's always exciting when you find out something new about your dream car.

Thanks for your time.
