535i 5spd in particular. what would one run in the 1/4 if i were to add the 4.27 rear diff, engine chip, dinan intake manifold, a full exhaust, and a CAI??

Is a 50shot of N20 safe on their engines for long term ownage?


Unfortunately im in Ca so i cant look into the possibility of a turbo/supercharger


also this is a little offtopic to the thread, but has anyone had a local shop rebuild their motor? I figure that any E34 ill find will have 150k+ on the clock and need a rebuild.
