- Tuning Flexibility: With an array of aftermarket parts available, tuners have limitless potential to modify the G35 900 2JZGTE VVTI for both street and track use. This makes it highly versatile for various driving styles.
- Unique Factor: A G35 900 2JZGTE VVTI swap is an attention-grabbing build. It stands out among typical G35 modifications and shows off a tuner’s engineering prowess.
Challenges of the G35 900 2JZGTE VVTI
While the G35 900 2JZGTE VVTI combination is enticing, the swap isn’t without its challenges. Here are some of the potential difficulties you may face:
- Engine Compatibility: The 2JZ is a Toyota engine, while the G35 is a Nissan vehicle. This means significant customization is required to ensure that the engine mounts, transmission, and other components align properly.
- Transmission Considerations: You’ll need to decide whether to use a Toyota or Nissan transmission. Popular options include the R154 transmission (from Toyota) or the CD009 transmission (from Nissan). Each has its pros and cons, but using a transmission that bolts directly to the 2JZ will simplify the process.
- Custom Fabrication: The swap requires a lot of custom fabrication, including motor mounts, intercooler piping, and exhaust components. This part of the swap can get expensive depending on the complexity of the build.
- Wiring and Electronics: Wiring a G35 900 2JZGTE VVTI requires custom wiring harnesses and ECU tuning to ensure the engine runs smoothly with the G35’s electrical system. This can be a time-consuming and tedious process, often requiring the help of a professional tuner.
- Cooling System: With increased power, the G35 will need a more robust cooling system. This includes a bigger radiator, upgraded fans, and potentially an oil cooler to ensure the engine stays cool, especially under heavy loads.
- Drivetrain Upgrades: The stock G35 drivetrain components, like the axles and differential, may not handle the increased power of the G35 900 2JZGTE VVTI. These will need to be upgraded to stronger parts to ensure reliability.
Steps to Perform the Swap
1. Planning and Research
Before diving into the swap, thorough research and planning are essential. You’ll need to gather information on required parts, tools, and costs. Decide on whether you’ll perform the swap yourself or hire professionals.
2. Engine and Transmission Acquisition
Locate a G35 900 2JZGTE VVTI and the accompanying transmission. Be prepared to source the engine from overseas, as this engine was never sold in North America. Ensure that the engine you purchase is in good condition by checking for any damage or wear.
3. Custom Engine Mounts and Fabrication
You’ll need to fabricate or purchase custom engine mounts to secure the G35 900 2JZGTE VVTI in the G35’s engine bay. This is where the swap gets tricky, as the dimensions of the 2JZ differ from the original VQ engine. Additionally, you’ll need to modify or fabricate exhaust headers, intercooler piping, and a driveshaft that fits the new setup.
4. Wiring and ECU Setup
One of the more challenging aspects of the swap is wiring. You’ll need a custom wiring harness to integrate the 2JZ’s electronics with the G35. In addition, the ECU will need to be tuned or replaced to ensure optimal performance. Some tuners opt for standalone ECUs like the Haltech or AEM Infinity, which allow for greater customization.
5. Cooling System Upgrade
Upgrade the cooling system to prevent overheating. This includes a large aluminum radiator, electric fans, and potentially an external oil cooler. The additional horsepower generated by the 2JZ-GTE will create more heat, so proper cooling is crucial.
6. Drivetrain and Suspension Upgrades
Upgrade the drivetrain components to handle the extra power. Stronger axles, a limited-slip differential, and a reinforced driveshaft are recommended. You may also want to consider upgrading the suspension to improve handling and grip.
7. Testing and Tuning
Once the swap is complete, the car should be thoroughly tested and tuned. This includes dyno tuning to optimize engine performance and ensure reliability. Keep an eye on temperatures, boost pressure, and other vital parameters to make sure the engine is running smoothly.
Cost of Swapping a 2JZ-GTE into a G35
Swapping a 2JZ-GTE VVT-i into a G35 can range in cost depending on various factors, including the condition of the engine, the parts used, and the amount of labor involved. Here’s a rough breakdown of potential costs:
- Engine and Transmission: $4,000 – $10,000 (depending on condition and source)
- Custom Mounts and Fabrication: $1,000 – $3,000
- Wiring and ECU: $1,000 – $3,000
- Cooling System Upgrades: $500 – $1,500
- Drivetrain Upgrades: $1,000 – $2,500
- Tuning and Dyno Time: $500 – $1,000
- Labor (if done by a shop): $3,000 – $7,000
Overall, a 2JZ swap can cost anywhere from $10,000 to $25,000 or more, depending on how extensively you modify the vehicle.
Performance Potential of a 2JZ-GTE VVT-i G35
One of the most exciting aspects of a G35 900 2JZGTE VVTI swap is the performance potential. With basic modifications such as a bigger turbo, fuel injectors, and an upgraded exhaust, this engine can easily reach 500-600 horsepower. With more advanced modifications, such as forged internals, a standalone ECU, and a high-performance fuel system, the 2JZ-GTE can surpass 1000 horsepower.
In a lightweight and well-balanced chassis like the G35, this level of power can make for a thrilling driving experience. Whether you’re building a track monster or a high-powered street car, the 2JZ-GTE VVT-i swap opens the door to serious performance potential.
FAQs
1. Is the 2JZ-GTE VVT-i swap street legal?
- The legality of the swap depends on your location and local regulations. Some areas may require emissions compliance, while others may allow engine swaps as long as they meet safety standards.
2. Can I use the stock G35 transmission with the 2JZ engine?
- The stock G35 transmission isn’t compatible with the 2JZ engine. You’ll need to use a transmission that can bolt up to the 2JZ, such as the R154 or the CD009.
3. How long does a 2JZ-GTE swap take?
- The swap process can take several weeks to a few months, depending on the complexity of the build and whether it’s done by a professional shop or at home.
4. Do I need to upgrade the suspension after the swap?
- Yes, upgrading the suspension is highly recommended. The extra power from the 2JZ-GTE will require stiffer springs, dampers, and potentially sway bars to improve handling and maintain traction.
5. Can a stock 2JZ-GTE handle 500 horsepower?
- Yes, a stock 2JZ-GTE VVT-i can handle around 500-600 horsepower with proper tuning and supporting modifications.
Conclusion
Swapping a 2JZ-GTE VVT-i engine into an Infiniti G35 is an ambitious project, but for many car enthusiasts, the rewards are well worth the effort.
