As I understand it, sprockets in the chain drive and/or the ring and pinion in the differential can be changed. Don't know anything about parts availability for your application, but it might be worth checking into.

First, this car IS FWD. As Norm points out, final drive parts can be changed, but it is a big deal. Also, any change to a higher numerical final drive WILL hurt gas mileage.

The 2.5 engine is the old Pontiac Iron Duke. Hipo parts used to be available for this motor. Frankly, the least expensive way to upgrade this car is to swap the complete drivetrain from a V6 version.
