The Mazda RX-7, particularly the FD model, is a beloved sports car known for its lightweight design and rotary engine. However, achieving significant horsepower, such as 450 HP, requires careful consideration of cost versus performance. This article explores the nuances of building a custom Garrett GT35 turbo setup for your FD RX-7.
Understanding the Basics of Turbocharging
Turbocharging is a method of forced induction that increases an engine’s efficiency and power output by forcing more air into the combustion chamber. For the RX-7, a custom Garrett GT35 turbo setup can be an excellent choice for reaching the 450 HP mark.
What is the Garrett GT35 Turbo?
The Garrett GT35 turbo is known for its reliability and performance. It is capable of supporting high horsepower levels while maintaining good spool characteristics. This makes it a popular choice among enthusiasts looking to enhance their RX-7’s performance.
Cost Considerations
Building a custom turbo setup involves various costs that can quickly add up. Here are some key components and their estimated costs:
- Garrett GT35 Turbo: $1,200 – $1,800
- Custom Exhaust Manifold: $800 – $1,500
- Intercooler: $300 – $800
- Fuel System Upgrades: $500 – $1,000
- Tuning: $500 – $1,000
In total, the cost of achieving 450 HP can range from $3,000 to $6,000, depending on the quality of parts and labor involved.
Performance Gains
Achieving 450 HP from your RX-7 with a Garrett GT35 turbo setup can provide significant performance improvements:
