Can one fit a 1GZ-FE engine into a 1988 Jaguar XJS?

Fitting a 1GZ-FE engine into a 1988 Jaguar XJS is technically possible but would require significant modifications. The 1GZ-FE, a V12 engine from Toyota, may not align with the existing engine mounts, transmission, or electronics of the Jaguar. Custom fabrication for mounts, wiring, and possibly even cooling systems would be necessary. Additionally, proper attention to compatibility with the vehicle's drivetrain and weight distribution is crucial for performance and safety.
