Cooler heads allowed higher compression and more power. I do know they can be a bit hard to get the air out of, but they do okay.

I am their designated "expert" (heh) and have done well so far. But the little wagon got dinged in a parking lot (no paint damage). Who knows a good paintless dent removal service in or near Bethesda MD? I want them to stay happy. Jon Brush Newton MA PS: Sorry for aggravating those who are getting this twice, or three times. Casting a wide net. ------------------------------ Date: Tue, 11 Sep 2007 22:54:18 -0400 From: KMS- Brett Anderson <[EMAIL PROTECTED]> To: UUC Digest <[email protected]> Subject: Re: 323i Wagon Message-ID: <[EMAIL PROTECTED]> Hi Bill. Any M or S 50/52/54 variant manual trans will work fine, 5 or 6spd. But if it didn't come from an E46, you'll need a custom drive shaft. Best to find one from an E46 and get all the necessary parts. Pedal box is the same, just swap brake, add clutch. All mounts are in place for switches, etc. Wiring will be a pain without extensive knowledge of the systems. Lots of coding and programming also. Basically, it would have to be dirt cheap to even think about it. Better to find a good auto and fix it to drive rather than try to convert a car that is already available with a manual trans.
