Understanding the 3B-REW Engine
The 3B-REW engine, known for its robust design and performance potential, has captivated tuners and racers alike. This engine is often found in the Mazda RX-7 and is celebrated for its rotary design, which allows for high RPMs and a unique power delivery.
Popular Upgrades for the 3B-REW Engine
- Aftermarket Turbocharger
- High-Performance Exhaust System
- ECU Tuning
- Upgraded Intercooler
- Cold Air Intake
Aftermarket Turbocharger
One of the most significant upgrades for the 3B-REW engine is the installation of an aftermarket turbocharger. This modification can lead to substantial power increases, often in the range of 30-50% depending on the specific turbo model and boost levels.
High-Performance Exhaust System
A high-performance exhaust system is essential for improving airflow and reducing back pressure. This upgrade not only enhances the engine’s sound but can also yield power gains of 10-20 horsepower.
ECU Tuning
ECU tuning is crucial for optimizing engine performance. By recalibrating the engine’s computer, tuners can adjust fuel maps and ignition timing, resulting in power gains of 15-25 horsepower.
Upgraded Intercooler
Installing an upgraded intercooler helps to lower intake temperatures, which is vital for maintaining performance under boost. This upgrade can lead to a 5-15 horsepower increase while also improving engine reliability.
Cold Air Intake
A cold air intake system allows the engine to breathe better by drawing in cooler, denser air. This modification can result in power gains of approximately 5-10 horsepower, making it a popular choice among enthusiasts.
