How much horsepower does a 1988 Toyota MR2 supercharged have?
The 1988 MR2 equipped with Toyota’s 4A-GZE supercharged engine typically produced about 145 horsepower in the U.S. market. In several international markets, the figure was higher—roughly 158–160 horsepower—depending on local tuning and rating standards.
To understand the figure, it’s important to note the era’s divergent horsepower ratings. U.S. cars commonly used SAE net ratings, while many other regions used different standards or gross ratings, which can lead to apparent discrepancies in published numbers. The MR2’s 4A-GZE engine was designed to deliver strong mid‑range torque and lively responsiveness for a light, mid‑engined sports car.
Engine powerplant: the 4A-GZE in the MR2
The MR2’s performance came from Toyota’s 4A-GZE, a 1.6-liter inline-four with a Roots-type supercharger and intercooler. The boost is tuned to deliver traction-friendly power at lower to mid RPMs, emphasizing real-world acceleration over raw peak horsepower.
Before the following list: The horsepower figures below summarize typical published numbers by market for the late-1980s 4A-GZE MR2.
- United States (1987–1989): about 145 horsepower (SAE net) for the MR2 with the 4A-GZE engine.
- Japan/Europe (late 1980s): about 158–160 PS (roughly 156–158 horsepower), reflecting different rating standards and tuning.
These variations reflect rating standards (SAE net vs. gross) and regional tuning rather than a single global figure. They capture how the car felt on the road as much as what the dyno read.
What the numbers meant for driving
With its compact mid‑engine layout and a lightweight chassis, the MR2’s 4A-GZE offered a lively driving experience. The supercharger delivered boost at lower RPM, helping the car respond quickly when accelerating from a standstill or overtaking on highways.
Summary
The 1988 Toyota MR2 with the supercharged 4A-GZE engine typically delivered around 145 horsepower in the U.S., with international variants commonly cited in the 156–158 horsepower range. Across markets, the engine’s torque delivery and the car’s nimble, mid‑engined balance made the MR2 a spirited performer for its era.
