The JDM GTX model featured four-wheel drive, viscous limited slip differentials and a turbocharged 1.8 L BP engine.
In the U.S. the Protegé came with a 1.8 L SOHC non-turbocharged engine, along with 4WD.
The JDM GT-R rally homologation version was added in 1992, featuring a number of enhancements over the GTX model: an aggressive front bumper, grill and bonnet vents, updated rear bumper, wheel flares, stiffer suspension and anti-roll bars with thicker cross members, and homologated five-stud wheel hubs with larger brakes.
The interior was fitted with leather and suede seats, and had the option of replacing the cupholder with a 3 gauge cluster.
In addition, the GTR has stronger connecting rods and pistons, larger oil squirters, larger nose crank, larger oil cooler, sodium filled valves, a baffled inlet manifold, larger injectors (from 360cc (black) to 440cc (orange)), removed boost cut, front-mounted intercooler, and an IHI VJ-23 ball bearing water-cooled turbocharger.
Both the GTX and GTR models were limited to a top speed of 180 km/h.
However, removing a screw on the back of the instrument cluster, labeled 180 km/h, meant that the speed limiter was removed.

The GT-R produced 210 PS (154 kW) compared to the GTX with 185 PS (136 kW).
300 special version GT-R's were produced known as GT-Ae's.
These shared the power output of the GT-R, but were 30 kg (66 lb) lighter, fitted with closer ratio gearboxes, and featured a larger top spoiler with a gap between the hatch and the spoiler to direct air to the new lower spoiler.
The wiring for ABS, A/C, power mirrors, power windows, power locks, and sunroof was removed.
Instead of using the GTR's leather interior, the lighter cloth interior of the GTX was used.
