Finished the turbo swap. While the GT -17 may still be a bit bigger than optimal for the low end I feel I accomplished my purpose. Advantages: Improved low end acceleration, I can now shift without falling below the boost level, I can go up a hill at less than 2k rpm and still accelerate, still have good top end (above 75mph) pickup, quietness - the original screamed a lot even after being rebuilt. I don’t feel such a sudden boost at spool up. Before the engine would get the shakes idling after running down the freeway for awhile. That seems to be much improved. Some pics:
