M50 non vanos rods and stock pistons will work for that. ARP head bolts is a good idea as well.E30 325ix M50 turbo 7 spd DCT 4wd 840awhp @ 31 psi.

With M50 non vanos rods you will get lower cr, they are 5mm shorter than stock :)

You dont need to touch the head for 300whp. Stock head gasket and ARP is enogh.E30 325ix M50 turbo 7 spd DCT 4wd 840awhp @ 31 psi.
