e30 M3 with a s85 v-10, just wow!!

I thought I was being thrify and kinda old school hot rod by planning to put a M30 into my e30.  This guy has pretty much outdone the modest M30 with his v-10??!!  Uhhh, where exactly do you find a M5 V-10 laying around?  Amazing vid that needs full screen, HD and loudness.
