What model do you have?

Sounds like an Sx2 for sure.

You can swap a SOHC tranny. I'm about 2k-2.5k at 75MPH.

The SC2 has a DOHC, and from the power band you're describing it is the DOHC, same as mine.

Time to read up & learn about the S-Series.

You still have the same engine... How could you possibly lose horsepower by swapping to another manual transmission?

However, your car will have slower acceleration with the longer gearing.

I find it as a decent tradeoff. The car might be slower off the start, but I don't have to shift as often, engine (and exhaust/intake) noise is lowered due to turning lower RPMs at highway speeds, and gas milage is slightly increased (though only a minor improvement).
