Speaking of torque, you bought the wrong car if that's what you were looking for. It's hard to get unless you turbo. I would recommend pulley's from NST and a clutch/flywheel setup if your trying to get some more torque down low. 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.
