Increasing mid range power

[The MaDDeSTMaN]

I was just wondering, what modifications would be best for increasing mid-range (2500rpm to 5000rpm) power and torque.

I thought about posting this in the Escort or the 4 cyl sections, seeing as I am specifically interested in boosting the power that my 2L OHC Pinto in my Escort makes, but then I realised that the methods to achieve this increase would probably be similar for most engines.

I know, it may seem stupid to some people, seeing as I'm talking about an engine that can rev to 6 grand and beyond without trouble, but I'm not interested in revving the rings out of my engine, and an increase in power and torque lower in the rev range would be much more useful in day to day driving, I'm not after ultimate power, and I want to keep low rev drivablility as much as possible, and I don't want fuel economy to suffer drastically.

I'm guessing getting a aftermarket cam designed to work best at those sort of revs would be a good start (one designed for towing with an auto, so setup for good torque low in the revs, for example), but what else would help, and am I wrong with that idea of the cam? What sort of extractors would help (4-2-1 or 4-1) or would the stock exhaust be better? I'm guessing there woul dbe no real need for changing the carby, but am I wrong?

Finally, would I be better off going for more traditional modifications and getting it working better higher in the revs and sacrificing low rev driveability.

Thanks.
