The 13B-REW engine, known for its rotary design and high-revving capabilities, has captivated automotive enthusiasts and tuners alike. To maximize its performance, selecting the right intercooler and exhaust system is crucial. This article explores the best options available for achieving peak power and reliability in your 13B-REW.
Understanding the 13B-REW Engine
The 13B-REW is a part of Mazda’s Wankel rotary engine family, specifically designed for the RX-7 models produced from 1992 to 2002. Its lightweight design and unique rotary mechanism allow for high power output relative to its size. However, to harness its full potential, modifications are often necessary.
Importance of Intercoolers
Intercoolers play a vital role in cooling the air entering the engine, which can significantly improve performance. Cooler air is denser, allowing for more oxygen to enter the combustion chamber, leading to better combustion and increased power.
Top Intercoolers for 13B-REW
- GReddy Type RS Intercooler: Known for its efficient cooling capabilities and lightweight design, the GReddy Type RS is a popular choice among 13B-REW owners.
