Hey guys, I'm trying to get advice from as many people as possible because I'm going to perform the impossible. I'm in the middle of building a 1200rwhp 5 series. So far its an M30 head with a custom 290 cam with an 11.2 mil lift, custom racing light weight rockers from korman, billet rocker retainers, triple titanium valve springs, ported and polished, an M102 block with custom hyperstrength rods, and intake manifold i am biulding with equal length runners and 12 injector slots, and an M5 drivtrain on the way. there is more but i realized it was too small for my aplication after I bought it so if anyone needs spare parts including performance parts ask away. All I ask is for small advice on how to suck hidden horsepower on these engines because I know their capabilities, and boy can they pump power, even reliably. I'll be responding to any replies daily and i hope this turns out to be a very large thread because there are still untold secrets of the turbo m30.![]()
