All you need for 500-550 hp is a 62 turbo =P
As far as 71 vs 74, I'm pretty sure they clip the turbine on the 74 wheel which makes it less efficient so it probably flows about the same as the 71. Then again we'll probably never see a turbine map for either so wth? 71 turbine sounds great out the exhaust.
You don't have to clip it depending on the housing.
