Does the 2006 Lexus GS300 have a 2JZ?
The 2006 Lexus GS300 uses a 3.0-liter inline-six from Toyota's JZ family, specifically the 2JZ-GE. It is not the turbocharged 2JZ-GTE.
In the 2006 model year, the GS300 occupied Lexus's middle ground in the GS lineup, offering a refined sedan powered by the well-known JZ architecture. The 2JZ family spans both naturally aspirated and turbocharged variants, but the GS300 relies on the non-turbo 2JZ-GE rather than the turbocharged 2JZ-GTE.

The GS300 is powered by a 3.0-liter inline-six from the Toyota JZ engine family. The engine code used by Lexus for this car is 2JZ-GE, a naturally aspirated configuration that features DOHC and 24 valves. Many versions include Toyota's VVTI variable valve timing to optimize torque across the rev range. It is not turbocharged from factory.
Key engine facts for the 2006 GS300:
- Engine code: 2JZ-GE
- Displacement: 3.0 L (2,998 cc)
- Valvetrain: DOHC, 24 valves
- Induction: Naturally aspirated
- Power output: Generally in the low- to mid-200s horsepower range, depending on market and tuning

Engine lineage: 2JZ-GE vs 2JZ-GTE
Understanding the difference helps clarify common questions among enthusiasts. The 2JZ-GE is the naturally aspirated version found in models like the IS300 and GS300, offering robust, reliable power without forced induction. The 2JZ-GTE is the turbocharged variant used famously in the Toyota Supra and certain other performance applications. Both share the JZ family’s basic architecture, but their induction and tuning diverge significantly.
Summary
In short, yes—the 2006 Lexus GS300 uses a 2JZ engine, specifically the 2JZ-GE inline-six. It is a non-turbo, naturally aspirated member of the JZ family, distinct from the turbocharged 2JZ-GTE found in other Toyota performances. This distinction helps explain why the GS300 delivers smooth, refined power without turbocharged acceleration characteristics.
