Turbosmart Boost Control & Turbochargers at JXL Performance

When you start increasing the boost pressure on a turbocharged engine, the fragile factory plastic valves are usually the first components to fail. Engineered in Australia and tested in the harshest motorsport environments, Turbosmart is a global authority on extreme boost control. Whether you are running a simple Stage 1 remap on a daily driver or pushing massive pressure through a dedicated track weapon, upgrading to Turbosmart hardware ensures your turbocharger operates efficiently and holds boost perfectly all the way to the redline.

Billet Diverter Valves and Upgraded Actuators

Factory diverter valves are notoriously weak, prone to splitting and leaking boost pressure when subjected to aftermarket ECU calibration. Turbosmart solves this issue with their legendary range of billet aluminum diverter valves, available in fully recirculating setups for a stealthy factory approach, or dual port dump valves for the classic atmospheric venting sound. Utilizing precision brass pistons and high temperature viton O rings, these valves completely eliminate boost leaks and significantly sharpen throttle response.

Beyond diverter valves, managing exhaust gas is critical for maintaining a stable boost curve. Turbosmart manufactures heavy duty internal wastegate actuators that utilize stiffer springs to prevent the wastegate from blowing open prematurely under high exhaust back pressure, ensuring your turbo spools faster and holds peak torque longer.

Advanced Boost Control and Complete Turbochargers

While they built their reputation on mechanical valves, Turbosmart has heavily expanded their engineering capabilities. They now offer highly advanced electronic boost controllers and even complete performance turbocharger assemblies designed for maximum airflow. These upgrades are heavily relied upon across the modern tuning community. They are essential for locking down boost pressure on the Ford EcoBoost engines found in the Mk7 and Mk8 Fiesta ST, and highly popular for replacing the leaky factory valves on the VAG EA888 powered VW Golf R Mk7 and Audi S3. They also provide the critical wastegate control required when pushing the heavily tuned BMW N55 and B58 platforms to their absolute limits.

JXL Performance supplies genuine Turbosmart boost control hardware to enthusiasts worldwide. Please check individual product listings for accurate availability, as lead times can occasionally vary for complex electronic boost controllers or complete turbocharger units.
