Any 97-01 will be a vtec 2.2 litre engine. The differences in horsepower from year to year are slight and depend as much on the year, exhaust header and tranny setup. The Base 5 speed is probably the most popular. If you are looking for a car with the ATTS (torque transfer) then the SH version is what you want; but be forewarned that this model is limited as to certain modifications and is not meant for drag racing. The final choice and one that will do fine for over the road use is the SS (automatic tranny). This last one suffers from failure issues when pushed really hard.
