Engine Mounts: Custom engine mounts would need to be fabricated to support the LS7 engine properly in the Rx7's engine bay. This might require alterations to the subframe and the chassis.
Transmission and Drivetrain: The LS7 engine has a different transmission pattern and bolt pattern compared to the rotary engine in the Rx7. A compatible transmission, such as a T56 manual or 4L60E automatic, would need to be sourced and installed. Custom driveshafts and modifications to the differential might also be necessary.
Fuel System: The LS7 engine requires a specific fuel injection system, which would need to be installed along with a compatible fuel pump and fuel lines.
Exhaust System: A new exhaust system would be needed to accommodate the different engine configuration.
Cooling System: The Rx7's cooling system may not be sufficient for the LS7 engine's requirements. Upgrading the radiator, water pump, and hoses might be necessary.
Electrical System: Modifications to the electrical system, including the wiring harness, may be needed to integrate the LS7 engine into the Rx7's electrical architecture.
Engine Management System: An aftermarket engine management system, such as a standalone ECU, would be needed to control the LS7 engine's operation.
It's important to note that fitting an LS7 engine into an Rx7 is a complex project that would require extensive knowledge and expertise in automotive mechanics and engineering. It's not a straightforward swap and would likely require significant time, effort, and cost.
