Why Use a 56mm External Wastegate?
Wastegate sizing is an important consideration when designing a turbocharger system. A 56mm external wastegate provides a larger exhaust-flow path than smaller wastegate configurations, making it an option for turbo systems where additional wastegate flow capacity is desired.
The external design allows the wastegate to be mounted separately from the turbocharger, typically using a turbo manifold or other compatible exhaust-side hardware.
The correct wastegate size ultimately depends on the turbocharger, engine, exhaust manifold, turbine characteristics, desired boost level, and overall system design.
Dual-Port Top Design
The dual-port top configuration gives the PW56 additional flexibility when configuring the wastegate’s control system.
The upper ports can be used as part of a pneumatic boost-control strategy, depending on the specific setup and controller being used. Always follow Precision Turbo’s installation and configuration requirements when plumbing the wastegate.
Precision Turbo GEN2 PW56
Precision Turbo & Engine is well known for its turbocharger and forced-induction components, and the GEN2 PW56 is designed as a performance-oriented external wastegate for turbocharged applications.
The 56mm configuration makes it particularly relevant to larger turbo systems and builds where wastegate flow capacity is an important part of the overall boost-control strategy.
Application
The GEN2 PW56 is intended for turbocharged vehicle applications, including:
- Performance street cars
- Track cars
- Race vehicles
- Turbocharged trucks
- Custom turbo builds
- High-performance forced-induction systems
This is a performance component rather than a vehicle-specific replacement part. Verify manifold compatibility, mounting dimensions, discharge routing, and boost-control plumbing before installation.

Frequently Asked Questions
What size is the Precision GEN2 PW56 wastegate?
The GEN2 PW56 is a 56mm external wastegate.
What does PW56 mean?
PW56 identifies Precision Turbo & Engine’s 56mm external wastegate configuration.
Does the PW56 have a dual-port top?
Yes. This version is specified with a dual-port top.
Is the PW56 a vehicle-specific replacement?
No. It is a performance-oriented external wastegate designed for turbocharged systems. Compatibility with a particular vehicle depends on the turbo manifold and overall turbo system.
Is a 56mm wastegate better than a smaller wastegate?
Wastegate sizing depends on the complete turbo system. A larger wastegate can provide greater exhaust-flow capacity, but the appropriate size depends on factors including the turbocharger, engine, turbine, manifold, and desired boost-control strategy.
Does this include a turbocharger?
No. The PW56 is an external wastegate and is sold as a separate turbo-system component.
