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...

Same housing as the 78 is the biggest you can machine for that compressor housing.

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.
