The Toyota 4A-GZE is a performance-oriented,1.6-liter, supercharged, DOHC inline-four engine from Toyota’s A-series engine family, based on the naturally aspirated 4A-GE engine. It was famously used in the first-generation Toyota MR2 from 1987-1989 and featured stronger internal components than the base 4A-GE, an electric magnetic clutch supercharger, and an intercooler. The engine is known for its excellent performance for its size and is a popular choice for engine swaps and performance modifications, though it has relatively poor low-end torque.
Key Characteristics
Engine Type:1.6-liter, inline-four, DOHC.
Aspiration:Supercharged.
Internals:Features stronger components than the naturally aspirated 4A-GE to handle the added stress of forced induction.
Supercharger:Equipped with a supercharger with an electric magnetic clutch that engages at specific RPMs to provide a boost.
Intercooler:Includes an intercooler to cool the compressed air before it enters the engine.
Common Applications & Popularity
Vehicle Fitment:The 4A-GZE was factory-installed in the first-generation Toyota MR2 (AW11).
Engine Swap:It is a common engine swap in vehicles like the Toyota Corolla AE86.
Performance:It’s a popular platform for tuners due to its compact size and high-revving nature, though it requires significant modifications to achieve high horsepower levels.
Compared to other 4A-GE variants
Lower Power Output (vs. 20-valve):
The supercharged 4A-GZE produced around 145 horsepower, which is less than later 20-valve 4A-GE engines.
Stronger Internals (vs. naturally aspirated):
While the 4A-GE was available in 16-valve and 20-valve versions, the GZE variant included reinforced internals and forced induction for better power and reliability.
The Toyota 4A-GZE is a 1.6-liter, DOHC, 16-valve inline-4 engine that was produced in two main generations between 1986 and 1995. Both generations were equipped with a factory-fitted roots-type supercharger and a strong 7-rib cast-iron block.
