Guys, understand the cost is not the factor here. I just want to know if the 76 will be a faster spooling turbo, smaller in physical size, and meet my goal of 600rwhp easily. Just because the 78 is the same price doesn't mean it will be a better turbo. 600rwhp in my car is probably pushing the limits of the car as it is! LOL If the 78 is what I need then I will buy that one.

Oh and forcedinductions.com is $150 less for the same turbo(either one)....just saying...

Size will be the same, spool you won't notice a difference, and the 78 will make the same power with less boost which will also help lower the iats. I see no reason not to upgrade to the 78mm for the same price in this situtation.
