Durable Piston Design
Turbocharger exhaust components operate in a high-temperature environment. The Granatelli 50mm wastegate uses a piston-style construction designed for durability in demanding turbo applications.
Its design makes it suitable for performance builds where repeated exposure to elevated exhaust temperatures and boost pressure requires robust wastegate hardware.
Designed for Performance Turbo Builds
The 50mm size makes this wastegate intended for larger turbocharged performance applications where appropriate exhaust-flow control is required.
Potential applications include:
- Street turbo builds
- Track cars
- Racing applications
- Custom turbo systems
- High-performance engine projects
- Turbocharged performance vehicles
Because wastegate sizing and flow requirements vary significantly between combinations, the 50mm size should be matched to the specific turbocharger and engine setup.
Universal-Style 50mm Application
The supplied product information describes this wastegate as having universal 50mm fitment for compatible turbocharged setups.
However, universal does not mean that it bolts directly onto every turbo manifold. Verify the mounting flange, physical dimensions, exhaust routing, actuator configuration, and available clearance before purchasing.

Installation & Fitment
The Granatelli 50mm wastegate is intended for custom or compatible turbocharger systems rather than a specific vehicle application.
Before installation, verify:
- Wastegate diameter requirements
- Manifold flange configuration
- Wastegate mounting location
- Exhaust flow direction
- Wastegate discharge routing
- Clearance around the wastegate
- Boost-control configuration
- Spring or pressure requirements for your setup
Installation should follow the requirements of your turbocharger and exhaust-manifold configuration.
Do not assume that a 50mm wastegate will bolt directly to an existing manifold simply because the manifold uses a 50mm wastegate. Flange design and dimensions must be compatible.
Why Use an External Wastegate?
An external wastegate gives a turbo system a dedicated method of bypassing exhaust flow around the turbine.
Compared with relying exclusively on an internal wastegate, an external setup can offer greater flexibility for custom turbo manifolds and performance exhaust systems.
The correct wastegate should be selected based on the turbocharger, engine displacement, expected airflow, exhaust energy, target boost, manifold design, and intended use.
Frequently Asked Questions
What size is the Granatelli Motor Sports wastegate?
This model uses a 50mm wastegate design.
Is it an external wastegate?
Yes. The product is designed as an external wastegate for turbocharged applications.
What type of internal design does it use?
The wastegate uses a piston-style design.
Is this wastegate vehicle-specific?
No specific vehicle fitment was provided. The supplied information describes it as a universal-style 50mm wastegate for compatible turbocharged systems.
Is the 50mm measurement enough to determine fitment?
No. You also need to verify the mounting flange, physical dimensions, exhaust routing, and available clearance.
Can I use it for a street car?
The supplied product information identifies the wastegate for street performance, track, racing, and turbo applications.
Does it prevent overboost?
A properly functioning and correctly configured wastegate is an important part of turbocharger boost control. However, no wastegate by itself guarantees that an engine cannot experience overboost. Proper sizing, spring selection, boost-control hardware, and system calibration are all important.
Granatelli 50mm Wastegate for Turbocharged Performance
The Granatelli Motor Sports 50mm Piston Design Wastegate is designed for turbo enthusiasts looking for responsive exhaust-flow management in custom performance applications.
With its 50mm piston-style design and universal-style application, it provides a foundation for street, track, and racing turbo systems where precise wastegate control is an important part of the overall build.
