Market-by-market horsepower figures
Below are the typical official ratings reported for the Supercharged variant, which varied between regions due to tuning and emission requirements. This gives a sense of the power difference between US-spec and Japanese-spec cars.
- United States (1989 MR2 with 4A-GZE): 145 hp (approximately 108 kW) at about 6,000 rpm.
- Japan / JDM (4A-GZE MR2): about 165 PS (roughly 162–165 hp) at around 6,000 rpm.
These figures come from original brochures and period automotive literature. Real-world measurements can differ slightly due to wear, exhaust conditions, and ECU/tuning variations.
Context and performance framing
Engine design and its impact
The MR2’s 4A-GZE used a Roots-type supercharger to boost intake air, delivering stronger mid-range torque and stronger acceleration compared with the naturally aspirated 4A-GE that powered the NA variant. That setup helped the AW11 MR2 feel brisk for its era, especially in traffic and around town, while still offering a lightweight, driver-focused chassis.
How it sits in the broader MR2 lineup
Compared with the NA 4A-GE engine, the supercharged 4A-GZE offered a clear performance boost. In the US, the 145 hp rating placed the MR2 as a lively sports car for its time, though it remained less powerful than some turbocharged contemporaries. In Japan, the slightly higher figure reflected stricter tuning and market preferences for spirited small-car performance.
Notes for enthusiasts and restorers
Horsepower numbers are best viewed as official ratings from the era. When restoring or modifying a 1989 MR2 with the 4A-GZE, owners often reference these baselines, while acknowledging that modern measurements or dyno tests can yield small deviations depending on condition, exhaust, intake, and intercooler configurations if present.
Summary
For the 1989 MR2 equipped with the 4A-GZE supercharged engine, typical horsepower ratings are around 145 hp for US-spec cars and about 162–165 hp for Japanese-spec versions. These figures reflect manufacturer specifications from the era, with real-world results influenced by condition and tuning. Overall, the supercharged variant provided a meaningful performance uplift over the naturally aspirated MR2, helping define the AW11’s reputation as a nimble, age-defining sports car.
