Swapping a VR4 engine into a 3000GT Mitsubishi is possible, but it requires significant modifications and fabrication work. The VR4 engine is a twin-turbocharged V6, while the 3000GT typically came with a naturally aspirated V6. To fit the VR4 engine into the 3000GT, custom engine mounts, exhaust system, and intercooler piping will need to be fabricated. Additionally, the wiring harness and engine control unit (ECU) will need to be modified to accommodate the VR4 engine.
Due to the complexity of this engine swap and the potential for significant modifications, it is generally recommended that this type of project be undertaken by experienced mechanics or professional automotive workshops.
