I read an article today in "Total BMW" magazine about an AC schnitzer E46 that they called the AS3 (only offered in europe of course), which has a 375hp NA M52TU 3.2 litre. Im really more interested in the engine. All it said in the article was bespoke, performance pistons, and forged conrods. Thats alot of power from an NA M52TU. They must have done more to the engine than that. I looked online a bit but I havent found anymore info about it. Its for sure an m52Tu, NOT an S54 or S52 either. ANYWAY, kinda cool I guess, thought I'd share and see if you fellow E46 geeks know anything about it.
