It's significantly faster. The TD04s are primarily used in 2.0L-2.5L 4-cyl applications because of the fast spool, AND the abiliity to generate more than adequate CFM through the engine. I think it's something like 430-450 CFM for a TD04H (This unit for sale is the slightly larger TD04HL. The H or HL designates the dimension of the center section.) Saab used to use Garretts, but uses Mitsu units in the performance applications (9-3 Viggen, 9-5 Aero, etc). They're preferred over the non-ball-bearing Garretts for one reason: minimal turbo lag.
Spool for a 16T is pretty quick by any standards. I hear the whine at 2,500 RPM, and full torque happens for me about 2,800-3,200 RPM and it stays there for a while then slowly drops off. I dynoed early last fall and I was about 300 ft/lbs WTQ (Only about 230 WHP, though....I had a fueling problem that created a suction in the tank and killed my peak HP numbers. Actual HP is probably closer to 250-260..)
The T3/T4 used to be a popular upgrade unit for Saabs, especially the old-generation 900 guys. The T3/T4 .60 trim has a higher top end, but some feel that's offset by the slower spool.
