Torque Pwr Increase?

[HuGo]

Its easy to increase horsepower but i hear that torque is the best power that comes out of the engine. Even though you may add stuff to the engine, HP increases but not torque. Well what kind of aftermarkets increases torque and not just horsepower?

Just wondering, do our engines have Cam Gears or are they reffered to something else? If there are cam gears, what performance cam gears can i buy? After the DASC, what else can i do to increase power besides NickG?

When doing a 1.9 to a 2.1 conversion, what do you have to buy/replace to make the conversion?

1.9stock is 138hp, what does 2.1 become in HP? If the engine gets upgraded to 2.1, is the DASC still compatible? TIA.
