Noooo its nowhere near that. Its about $40-50k, as told to me by G-Power. It does require the bottom end to be built up though, but its included in the price.

 

Not that bad then. I think the $150k is for the complete "Hurricane" package. At $40-50k, it's about what the Dinan or RDSport strokers go for, but with 50+hp more. But at that price, you can get yourself a good E46 M3 with quite a bit to spare, so I guess it's still a ridiculously expensive mod.
