In this article, we will explore essential tips and part recommendations to help you reach this performance milestone.
Understanding the Rotary Engine
The heart of the RX-7 is its unique rotary engine, which provides a different tuning approach compared to traditional piston engines. Understanding its mechanics is crucial for optimizing performance.
- Lightweight design allows for better power-to-weight ratio.
- High-revving engine characteristics make tuning essential.
Essential Modifications for 350 HP
1. Upgraded Turbocharger
One of the most significant upgrades for achieving higher horsepower is installing a larger turbocharger. Consider the following options:
- Garrett GT28RS for quick spool and high power.
- Precision Turbo 6262 for maximum output potential.
2. Engine Management System
A quality engine management system (EMS) is critical for tuning your RX-7 to handle increased power. Recommended options include:
- Haltech Elite 750 for advanced tuning capabilities.
- AEM Series 2 for user-friendly interface and features.
3. Fuel System Upgrades
To support higher horsepower, you must upgrade your fuel system. This includes:
- High-flow fuel injectors (e.g., 850cc or larger).
