The Pure Turbos Pure850 upgrade for the Toyota Supra A90/A91 with the B58 6-port engine is a powerful enhancement designed to push the performance boundaries of the stock turbo setup. The Pure850 features a larger billet compressor wheel and an upgraded, stronger turbine wheel compared to the Pure800, allowing it to deliver higher airflow and power. It is engineered to support over 720 wheel horsepower (whp) with the right supporting modifications, making it an ideal choice for enthusiasts looking to maximize their Supra's capabilities.
The turbocharger also includes a high-flow, 3D-printed intake inlet, enhancing air intake efficiency. This component, along with the turbo's VSR balancing and upgraded bearing housing, ensures smooth and reliable operation even under high boost conditions. Despite its increased performance, the Pure850 is designed to maintain compatibility with the OEM housing, offering a balance between upgraded power and ease of installation.
The Pure850 is particularly suited for A90/A91 Supra models, offering both 2-port and 6-port configurations depending on the engine setup. It is important to note that to fully unlock its potential, additional upgrades such as enhanced fueling (e.g., high-pressure fuel pumps and injectors) and tuning adjustments are required. Many users opt for E85 fuel blends, allowing them to achieve peak performance figures during track and dyno testing.
This turbo upgrade is designed for use primarily in competition and racing environments, aligning with regulations that restrict such modifications for street use in certain regions. It can be purchased as a complete upgrade or with an option to send in a core for a refund, allowing flexibility in upgrading paths.
Overall, the Pure850 turbocharger is a popular choice among the Supra community for those seeking to elevate their car's power output while maintaining a relatively straightforward installation and a familiar OEM-like fit. It is a well-regarded solution for taking the performance of the A90/A91 B58 platform to the next level.
