Yes—the 2004 Lexus IS 300 is powered by the 2JZ-GE inline-6 engine, not the turbocharged 2JZ-GTE.
In the United States, the first-generation IS 300 (2001–2005 model years) used the Toyota-developed 2JZ-GE 3.0-liter inline-6. The 2JZ-GTE is a turbocharged variant of the same family and is found in the Toyota Supra, not in the IS 300. The IS 300’s engine is naturally aspirated and equipped with variants of Toyota/Lexus technology such as variable valve timing in later revisions. For buyers or collectors, this distinction helps set expectations for performance, maintenance, and parts compatibility.
