* Jeep Model and Year: The size and design of the Jeep's engine bay will drastically influence how much modification is needed. Older Jeeps generally offer more flexibility due to simpler designs. A newer, more compact Jeep might require extensive fabrication.
* Mustang Engine and Transmission: Different Mustang engines and transmissions have different dimensions and mounting points. A Coyote 5.0L V8, for instance, is significantly larger than a smaller 4-cylinder engine, and will present different challenges. The transmission's bellhousing and output shaft will also need to be compatible with a suitable transfer case (if you want four-wheel drive).
* Four-Wheel Drive System (if applicable): Adapting the Mustang's transmission to a Jeep's transfer case is a major hurdle. You'll likely need custom adapter plates, driveshafts, and potentially modifications to the Jeep's frame and suspension. This is often the most complex part of the project.
* Wiring and Electronics: Integrating the Mustang's engine and transmission computer systems with the Jeep's electrical system is a complex task requiring significant wiring and potentially aftermarket engine management solutions.
In short, while it's *possible*, it's a major project requiring significant mechanical and fabrication skills, specialized tools, and likely a substantial budget. It's not something a novice mechanic should attempt. You'll need extensive research, custom parts fabrication, and potentially professional assistance to complete the job successfully. Many Jeep enthusiasts opt for more readily available and compatible engine swaps instead.
