What are your goals for the car? What will you be doing with it? How much boost do you plan to run?

The .82 will have a little more lag but will ultimately make more power up top. But depending on what your doing, it may not even be necessary.

If its a stock sleeve block, the .63 will be plenty since you'll have to worry about cracking a sleeve before you'll run the turbo out of breath

if your redline is set at 7500 you want the.63 it give you a better power band the .82 wont spool up till 52-5500 really no fun on the street if your going to get head work and up your rev to 85-9500 then i would go with with the .82. good luck

.63 housing for sure.
