OT: Listen up BMW guys..., ...Looking for BMW resources Options

[BMXerror]

As some of you may know, I'm playing with somebody else's E36 325is right now, and I've been put in charge of developing the car. This includes lots of research, as well as sourcing parts. I'm just not quite up to speed as to who is reputable and who to avoid, or where to get good info.
The main thing I'm looking for is a decent forum. Something where people actually know something. And classifieds would be great. Also, any good parts sources would be helpful (I already know about Pelican (IMG:style_emoticons/default/smile.gif) ). Thanks in advance.
I might as well ask my current question while I'm on here. I'm looking to get a set of underdrive pulleys for the car. Evosport makes (or made) a set that looks good for a reasonable price, but they don't specify that it's for an M50 engine. They just say 'E36 3-series'. My question is, do the M50 and M52 engines both use the same pulley configuration, since they both came in the E36? Thanks again.

Wayne Dempsey's "101 Performance Projects For Your BMW 3 Series 1982-2000" book is a great start. I bought mine from Pelican, here.

I have a 1997 328i, and the book helped me with quite a few projects. The guys at Pelican are great to work with, their website is a great resource, their prices are reasonable, and shipping is quick.

The bimmerforums forum is unfortunately full of a lot of "drift, yo" knuckleheads. So beware of the info you get there... you'll need to sift thru a lot of garbage.
