Electronic Wastegate Integration with Race-Proven 50mm Flow Capacity for BMW Turbo Platforms
The Turbosmart TS-0565-1902 MSG50 Modular StraightGate50 is a 50mm butterfly-style external wastegate engineered to integrate directly with BMW factory electronic wastegate control motors. Based on Turbosmart’s award-winning StraightGate50 technology, the TS-0565-1902 eliminates reference hoses, springs, and diaphragms entirely, instead relying on the OEM electronic control unit to manage boost pressure with the precision and response that only full electronic actuation can deliver. The zero-offset butterfly valve design maximizes exhaust flow to 383.9 CFM, providing near-linear boost control across the entire operating range for maximum turbo performance on modified BMW platforms.

Frequently Asked Questions
What is the TS-0565-1902?
The Turbosmart TS-0565-1902 is the MSG50 Modular StraightGate50, a 50mm butterfly external wastegate designed specifically to integrate with BMW factory electronic wastegate control motors. It replaces the OEM wastegate while retaining electronic boost control without springs or diaphragms.
Which BMW models is the Turbosmart TS-0565-1902 compatible with?
The TS-0565-1902 is designed for BMW turbocharged platforms that use an electronic wastegate control motor compatible with the Turbosmart MSG50 bracket and linkage. Confirm specific fitment with Turbosmart’s published application guide for your BMW engine and turbocharger setup before ordering.
Does the Turbosmart MSG50 require tuning after installation?
Because the TS-0565-1902 retains the OEM BMW electronic wastegate control unit, it interfaces with the existing ECU boost management strategy. A tune may be required or recommended to optimize boost targets after installation depending on the extent of other engine modifications.
How does the zero-offset butterfly valve design improve boost control?
The zero-offset butterfly design minimizes valve offset from the seat centerline, which reduces turbulence and provides a more linear relationship between valve position and exhaust flow. This translates to smoother, more predictable boost control compared to poppet-style wastegate designs.
Can the TS-0565-1902 handle the power levels of a heavily modified BMW engine?
At 383.9 CFM flow capacity through a 50mm butterfly valve, the Turbosmart TS-0565-1902 is suited for high-output BMW builds. Verify that the flow rating matches or exceeds your turbocharger’s wastegate flow requirement for your target power level.
What is the difference between the Turbosmart MSG50 and their standard StraightGate50?
The standard StraightGate50 uses pneumatic spring actuation, while the MSG50 Modular series is designed specifically to mate with OEM electronic wastegate actuator motors on BMW and VAG platforms. The MSG50 requires no external boost solenoid or reference hose and relies entirely on the factory electronic control system.
Is the TS-0565-1902 made from stainless steel throughout?
The key structural components including the butterfly valve, shaft, main body, and V-band clamps are all stainless steel in varying alloys selected for high-temperature strength. The bracket and actuator are anodized 6262-T6 aluminum for weight reduction.
Does the Turbosmart MSG50 come with a warranty?
Turbosmart products are backed by the Turbosmart manufacturer warranty. Contact Black Ops Auto Works or Turbosmart directly for warranty claim procedures specific to the TS-0565-1902.
Installation Instructions
- Ensure the engine is cool before beginning wastegate replacement work.
- Locate the existing OEM wastegate on the BMW turbocharger exhaust housing.
- Disconnect the electronic wastegate actuator connector and remove the OEM wastegate assembly.
- Install the Turbosmart MSG50 bracket and mount the TS-0565-1902 to the turbo exhaust housing using the supplied V-band clamps.
- Connect the OEM electronic actuator to the Turbosmart MSG50 linkage arm per Turbosmart’s installation guide.
- Verify all V-band clamp seating and torque to specification.
- Start the engine and monitor for boost control function and exhaust leaks.
- Perform a tune or boost target verification as recommended for your specific BMW build.
