BUT, I'm wondering if the e90 M3 water pump is compatible with this engine? And if so, is it worth purchasing over the stock water pump?
I just noticed the M3 water pump on Turner's site, and it mentions an 'upgraded aluminum impeller' - I don't know if this would improve reliability...see links below.

Check Tischer's website. It's Getbmwparts.com. then look at their specials. I got a water pump T-Sat and the bolts for $478 shipped. There isn't really any need to replace the hoses and tank unless you see them cracking, and or leaking. If you have the extra cash and really want to go ahead, but it really isn't necessary. If you call turner with that special price they will match it. They are a great company and will help you with any thing, I didn't think of calling them before I bought mine. Hope this helps.
