What kind of engine does a 2006 Lexus GS300 have?
It uses a 3.0-liter inline-6 engine from Toyota’s 2JZ family, the 2JZ-GE, which is a naturally aspirated DOHC 24-valve unit delivering roughly 225 horsepower and about 210 lb-ft of torque.
In more detail, the 2006 GS300 sits in Lexus’ mid-2000s sedan lineup with a dedicated 3.0-liter six-cylinder engine that emphasizes smooth power delivery and reliability. The engine is part of the well-regarded 2JZ-GE family, typically paired with a five-speed automatic transmission in U.S.-market cars. Depending on the exact market and production batch, some variants employ variable valve timing on the intake cam, further smoothing response across rev ranges. This setup helped the GS300 balance refined highway cruising with capable everyday performance.

Does the Lexus GS300 have a 2JZ?
Yes, the Lexus GS300 has a 2JZ engine, specifically the naturally aspirated 2JZ-GE model, not the turbocharged 2JZ-GTE found in the Supra. The 2JZ-GE is known for its reliability and smooth operation, though it is not built for the same level of power as the GTE version.
- Engine type: The GS300 is equipped with the 2JZ-GE engine.
- Performance: This engine is a naturally aspirated (non-turbocharged) straight-six that produces around 227 horsepower.
- Comparison to Supra: The famous turbocharged 2JZ-GTE engine, which is famous for its high-power tuning potential, was never used in the GS300 from the factory. That engine was exclusive to the JDM Aristo in Japan and the Toyota Supra.
- Reliability: The 2JZ-GE is a very durable engine, but the stock automatic transmission in the GS300 is not designed to handle significant power increases.
