The Nissan Z car has long been a favorite among car enthusiasts, especially when it comes to tuning and modification. The RB20DET engine, a turbocharged inline-six, offers a fantastic platform for building power while maintaining a budget-friendly approach. In this article, we will explore the journey of transforming a naturally aspirated (N/A) Z car into a 400 horsepower beast using the RB20DET engine.
Understanding the RB20DET Engine
The RB20DET is known for its robust design and tuning potential. Originally designed for the Nissan Skyline, this engine has found a home in various Nissan models, including the Z car. Here are some key features of the RB20DET:
- Engine Type: Inline-six, turbocharged
- Displacement: 2.0 liters
- Power Output: Stock around 200 hp, easily tuned to 400 hp
- Aftermarket Support: Extensive options available
Choosing the Right Base Car
Before diving into the build, selecting the right base car is crucial. While the Z car is an excellent choice, consider the following factors:
- Condition: Look for a car with minimal rust and a solid chassis.
- Existing Modifications: A car with some upgrades may save you money.
- Budget: Ensure the purchase price fits within your overall budget.
Budgeting for the Build
Building a 400 hp RB20DET Z car on a budget requires careful planning. Here’s a breakdown of potential costs:
- Base Car: $3,000 – $5,000
- RB20DET Engine Swap: $2,000 – $4,000
- Turbocharger Upgrade: $500 – $1,500
- ECU and Tuning: $500 – $1,000
- Supporting Mods (exhaust, intercooler): $1,000 – $2,000
Engine Swap Process
The heart of the build is the engine swap. Here are the steps to successfully install the RB20DET:
- Preparation: Gather all necessary tools and parts.
- Remove the Old Engine: Disconnect all wiring, hoses, and mounts.
- Install RB20DET: Drop the new engine into place, ensuring all mounts align.
- Wiring and Connections: Connect the ECU, sensors, and all necessary wiring.
- Fluids and Testing: Fill with oil and coolant, then start the engine for the first time.
Boosting Power with Upgrades
Once the RB20DET is installed, it’s time to maximize its potential. Here are some upgrades to consider:
- Turbocharger: Upgrade to a larger turbo for increased airflow.
- Intercooler: Install a front-mount intercooler to reduce intake temperatures.
- Exhaust System: A high-flow exhaust will improve engine efficiency.
- Fuel System: Upgrade injectors and fuel pump to support higher power levels.
- ECU Tuning: Proper tuning is essential for reliability and performance.
Final Touches and Maintenance
After achieving your power goals, don’t forget about the importance of maintenance. Regular checks and services will keep your Z car running smoothly:
- Oil Changes: Change oil frequently to maintain engine health.
- Cooling System: Regularly check coolant levels and hose conditions.
- Suspension and Brakes: Upgrade for better handling and safety.
- Tire Maintenance: Ensure tires are properly inflated and in good condition.
Conclusion
Transforming a naturally aspirated Z car into a 400 hp RB20DET powerhouse is an exciting project that can be done on a budget. With careful planning, the right parts, and dedication, you can achieve impressive results without breaking the bank. Enjoy the journey and the thrill of driving your newly turbocharged Z car!
