You think you can make 300whp without a power adder on an M52 2.8L motor? Um, sure. It'll cost you about $30,000 and last for a few hours running 110oct, stand alone, 12+:1 compression with ITBs and radical cams with VANOS delete. You'd essentially have to build your own Eurospec S50 motor out of a 328i. Like Trevor said, aint going to happen. You can get a used blower kit from a U.S. forum for probably $4g
