I'm new at this forum so bear with me in case this has already been mentioned at length. I did a search but could not find mention of this, so I though I'd ask.

I currently own a '92 730i with the "big-six" M30. Obviously the 730i is not a race car, however we all always want more power right? So I've been searching for - amongst other things - a set of underdrive pulleys for this engine, but so far I've had no luck. Does anyone in here know of someone who can provide me with a set? Additionally I'm also eager for a lightened flywheel. Any help or suggestions are appreciated.
