What engine is in the Jzx90?
The JZX90 is powered mainly by Toyota’s 1JZ inline-six engine family: turbocharged 1JZ-GTE in the performance/turbo variants and naturally aspirated 1JZ-GE in the non-turbo models.
Engine options in the JZX90 lineup
Two primary engine options powered the JZX90 family, reflecting the range from everyday sedan to performance-focused models.
- 1JZ-GTE — 2.5-liter turbocharged inline-six, used in turbocharged JZX90 variants and tuned for higher performance.
- 1JZ-GE — 2.5-liter naturally aspirated inline-six, used in NA (non-turbo) variants for smoother, more accessible power delivery.
In short, the JZX90's engine lineup centers on the 1JZ family, with the turbocharged 1JZ-GTE powering the higher-end variants and the naturally aspirated 1JZ-GE available in base and mid-range trims.
Turbocharged 1JZ-GTE
The 1JZ-GTE is Toyota’s 2.5-liter turbocharged inline-six used in the higher-spec JZX90 models. It has a reputation for strong mid-range torque and strong peak horsepower in Japanese-market tuning, making it a popular choice among enthusiasts for performance builds.

Summary
Ultimately, the JZX90’s engine identity is anchored in the 1JZ family: 1JZ-GTE for turbo models and 1JZ-GE for NA models, across the Chaser, Mark II, and Cresta lines of the early 1990s. This combination defined the car’s performance spectrum and remains a key point for enthusiasts and restorers today.
In brief, JZX90 = 1JZ inline-six engines (GTE turbo or GE NA) across its X90-generation lineup, with turbo variants delivering the performance edge and NA variants offering everyday usability.
