3.0 si to csl

[gel9001]

Sorry if this has been posted before but I can't find anything. I own a 3.0 si and was wondering if the motor could be converted in essence to the 3.0 csl. My understanding is that the only difference between the two is the induction path and a computer chip. Has anyone done this, the gain would be about 30 hp.
thanks,
Gene

Don't you mean the 3.2 M3 CSL? or the CS...

A 330Ci M Clubsport

The M Clubsport trim level is aesthetically similar to the United States Performance Package The main difference is that the M Clubsport trim was not given the BMW performance camshafts that the ZHP obtained. Instead, it had 20 kilograms (44 lb) of sound deadening removed from the car. The M Clubsport trim shares the same suspension set up as the performance package (ZHP) in America, as well as the "cubed" interior trim and 18 inch style 135 wheels However, changes from the ZHP include plastic front splitters on the M-Tech II bumper, a M-tech II styled rear spoiler (instead of the M3 trunk lip), and clubsport door sills The M Clubsport also came with two "BMW Individual" colour options that were carried throughout the car, Estoril Blue and Velvet Blue

Unlike the other trim levels, the M Clubsport trim was only available on the 330

EDIT: just noticed you mention Si... they are different engines. yours is N52, CS is M54.

I think you have your wires crossed. The CSL engine was a variant of the M-powered S54 with the carbon airbox and different valve timings. Also the manifolds were straightened for some power gains. You could do a little more if you had the Z4M as someone on this very board has done here: http://www.z4-forum.com/forum/viewtopic.php?f=9&p=316369 but with your current engine. No dice.
