How to gain more torque, without spending shitloads?

[krogoth]

Sell the DC2R, buy a large engined car from the 90's. You might even make a few dollars.

But if you want to keep yoru DC2R, nothing short of adding forced induction or a bottle.

Stripping the interior of a DC2R is silly because most of the weight reduction is already done at the factory.
