The A90 Supra has taken the automotive world by storm with its impressive performance and tuning potential. Among the most sought-after upgrades are turbocharger replacements, specifically the BorgWarner S300SX3 and the Precision 6466. This article will compare these two turbo options, focusing on power gains, installation considerations, and overall performance.
Understanding Turbochargers
Turbochargers are essential components in modern performance vehicles, providing significant power increases by forcing more air into the engine. The A90 Supra’s factory turbo is efficient, but upgrading to a larger turbo can unlock even more horsepower and torque. Let’s dive into the specifics of the BorgWarner S300SX3 and Precision 6466.
BorgWarner S300SX3 Overview
The BorgWarner S300SX3 is a popular choice among tuners for its balance of performance and reliability. Designed for high horsepower applications, it offers a range of features that enhance its efficiency and output.
Key Features
- Compressor Wheel: 67mm inducer diameter
- Turbine Wheel: 62mm exducer diameter
- High-flow design for increased power
- Durable construction for longevity
Power Gains
With the S300SX3, users can expect significant power gains, typically ranging from 600 to 800 horsepower depending on supporting modifications. This turbo is well-suited for those looking to push their A90 Supra to the limits.
Precision 6466 Overview
The Precision 6466 is another strong contender in the turbo upgrade market, known for its exceptional performance and response. It is frequently chosen by enthusiasts looking for a blend of quick spool and high-end power.
Key Features
- Compressor Wheel: 66mm inducer diameter
- Turbine Wheel: 62mm exducer diameter
- Ball bearing design for faster spool
- Lightweight construction for improved response
Power Gains
The Precision 6466 can also deliver impressive power gains, typically between 600 and 750 horsepower. Its quick spool characteristics make it an attractive option for those who want immediate throttle response without sacrificing top-end power.
Installation Considerations
When upgrading to either the BorgWarner S300SX3 or the Precision 6466, several installation considerations must be taken into account. Proper installation is crucial for maximizing performance and ensuring reliability.
Supporting Modifications
- Upgraded fuel system
- Enhanced intercooler
