- Double overhead camshaft (DOHC) design
- Cast iron block for durability
- Aluminum DOHC cylinder head
- Variable valve timing (VVT) in some models
Introducing the Garrett T3 Turbo
The Garrett T3 Turbo is a popular choice for turbocharging applications due to its compact size and efficient performance. It is capable of delivering significant boost levels while maintaining reliability. The T3 turbocharger is designed to enhance engine performance by forcing more air into the combustion chamber, resulting in increased horsepower and torque.
Specifications of the Garrett T3 Turbo
- Compressor size: 60mm
- Turbine size: 48mm
- Maximum boost pressure: 15 psi
- Efficient for engines up to 300 hp
Performance Testing Methodology
The performance testing was conducted on a modified KA24DE engine equipped with the Garrett T3 Turbo. The testing involved a series of runs on a dynamometer to measure horsepower and torque output at various boost levels. The engine was tuned to optimize performance while ensuring reliability.
Testing Setup
- Engine: Nissan KA24DE
- Turbocharger: Garrett T3
- Fuel: 93 octane gasoline
- Tuning: ECU remap for optimal performance
- Boost levels: Tested at 7 psi and 15 psi
Results of Performance Testing
The results of the performance testing were impressive, showcasing the potential of the KA24DE engine when paired with the Garrett T3 Turbo. At a boost level of 15 psi, the engine achieved a remarkable increase in horsepower, reaching a total of 240 hp. This represents a 100 hp increase over the stock configuration.
Horsepower and Torque Output
