Water-Cooled External Wastegate Design
Turbocharger systems can generate significant heat, particularly around the turbine housing and wastegate. This MV-R/MV-R-style wastegate incorporates a water-cooled configuration intended to provide additional thermal management for demanding turbocharged applications.
The aluminum construction keeps the assembly compact while providing a durable housing for custom turbocharger installations.
44mm External Wastegate for Turbo Builds
A 44mm external wastegate provides an independent path for controlling exhaust flow around the turbocharger turbine. By regulating exhaust flow, the wastegate helps the boost-control system maintain the desired pressure according to the selected spring and control strategy.
This makes it suitable for custom turbo systems where an external wastegate is preferred over an internal wastegate arrangement.
Universal Application
This is a universal-performance component, rather than a direct-fit replacement for a specific factory vehicle.
It can be considered for:
- Custom turbocharger builds
- Performance street cars
- Track vehicles
- Race applications
- Fabricated turbo manifolds
- External-wastegate turbo systems
- Water-cooled turbocharger configurations
Because mounting dimensions and plumbing requirements can vary between turbo systems, verify the wastegate flange, available clearance, coolant connections, and installation dimensions before ordering.

Installation Considerations
Installation requires a turbocharger system designed to accommodate an external wastegate. Before installation, confirm:
- 44mm wastegate compatibility
- Mounting flange configuration
- Manifold or turbo housing clearance
- Wastegate discharge routing
- Coolant-line requirements
- Spring pressure requirements
- Boost-control configuration
Professional installation and proper boost-system calibration are recommended for modified turbocharged vehicles.
Frequently Asked Questions
Is this wastegate universal?
Yes. The listing identifies this as a universal 44mm external wastegate intended for turbocharged vehicle systems. It is not a vehicle-specific direct replacement.
What spring comes installed?
The wastegate comes with a 14 PSI spring pre-installed.
Are other springs included?
Yes. The package includes additional 7 PSI and 17 PSI springs for different pressure configurations.
Is this a 44mm wastegate?
Yes. The listed wastegate configuration is 44mm.
Is the wastegate water cooled?
Yes. This assembly uses a water-cooled configuration.
Is this a boost solenoid?
No. This product is an external wastegate assembly. It should not be confused with a turbocharger boost-control solenoid or vacuum solenoid valve.
Will a 14 PSI spring automatically produce 14 PSI of boost?
Not necessarily. Wastegate spring pressure is only one part of the boost-control system. Turbocharger characteristics, exhaust flow, boost-control hardware, and engine tuning can all affect actual boost pressure.
Upgrade Your Turbo System
If you’re building a custom turbocharged setup and need an adjustable 44mm external wastegate, this MV-R/MV-R-style assembly provides multiple spring options, aluminum construction, and water-cooling capability in a universal configuration.
