More so the flywheel than the clutch, but doesn't make much sense to upgrade one without the other.

That said I would beware running a pulley. The VQ shows very little gain from such a thing and also, it likes to be dampened. I would not do a pulley merely from the risk of resonance blowing your motor.
Now, if you found a Super Damper, then maybe you should replace the pulley.
The best way to get more torque is to remove as much of the comfort dampening as possible. Namely, our 28-32 pound, dual mass flywheel. I believe a vendor here (Zspeed?) makes a lightened steel flywheel that doesn't chatter too much and still weighs 20-21 pounds. Rotating mass is huge (literally). The VLSD tends to absorb a lot of the torque as well, although it is more driveable than a locky clutch type or an expensive as all hell gear type.
Poly-u engine mounts might also help quite a bit, but again, more NVH.
If you're indifferent, like me, you'd run all your mounts as polyurethane. No need for solid mounts, because that's just insane.
