1. Swap Engine Mounts:
- Replace your 350Z's original engine mounts with aftermarket mounts specially designed for the Nissan Skyline RB26DETT engine.
2. Transmission Modifications:
- Modify your 350Z's transmission bell housing to mate with the RB26's transmission. Alternatively, you can install an RB26-compatible transmission.
3. Wiring Harness Integration:
- Integrate the RB26DETT engine's wiring harness with the 350Z's electrical system. This may require custom modifications to the wiring.
4. Custom Headers:
- Fabricate custom exhaust headers to connect the RB26's turbochargers to the 350Z's exhaust system.
5. Fuel System Upgrade:
- Upgrade the fuel system to handle the increased fuel demands of the RB26. Install a high-flow fuel pump and larger fuel injectors.
6. Engine Management:
- Install an aftermarket engine management system to control the RB26DETT's fuel injection, ignition timing, and other critical parameters.
7. Cooling System Adaptations:
- Modify the 350Z's cooling system to accommodate the RB26's specific cooling requirements, such as repositioning the radiator and installing a larger radiator.
8. Gauges and Instrumentation:
- Install appropriate gauges to monitor the RB26's vital functions, including boost pressure, oil pressure, and coolant temperature.
9. Exhaust Modification:
- Adapt the 350Z's exhaust system to fit the RB26's turbocharged setup. Install downpipes, catalytic converters, and mufflers as necessary.
10. ECU and Tuning:
- Program the engine management system with a custom tune for the RB26 engine swapped 350Z. This step requires considerable expertise in tuning and should be performed by a professional tuner.
11. Final Testing and Adjustment:
- Once the installation is complete, perform thorough testing and fine-tuning of the engine, cooling, fuel, and electrical systems to ensure proper operation.
12. Safety Checks and Inspections:
- Conduct safety checks and inspections to verify the reliability and safety of the RB26-swapped 350Z. This may include emissions testing, dyno tuning, and road tests.
Note: This is a highly complex and technical procedure that should only be undertaken by experienced mechanics or automotive professionals. It's crucial to thoroughly research and plan before attempting an RB26 engine swap in a 350Z.
