Product Details
The Turbosmart Kompact Blow-Off Valve Replacement Trumpet (TS-0203-3004) is a genuine Turbosmart replacement accessory designed for compatible Kompact Dual Port and Plumb Back blow-off valves. Featuring a precision-machined aluminum construction and black finish, this replacement trumpet provides a convenient solution for replacing a damaged, missing, or worn blow-off valve outlet.
Designed specifically for Turbosmart's Kompact blow-off valve platform, the TS-0203-3004 helps restore the original outlet configuration without requiring replacement of the complete blow-off valve assembly.
The trumpet-style outlet provides an atmospheric discharge path for compressed air released during blow-off valve operation. When the throttle closes under boost, the blow-off valve opens to relieve excess charge pressure, helping reduce compressor surge and associated stress on turbocharger components.
For enthusiasts using a compatible Kompact Dual Port blow-off valve, the replacement trumpet helps maintain the valve's characteristic atmospheric discharge sound while preserving its intended outlet configuration.
Manufactured as a genuine Turbosmart replacement component, the TS-0203-3004 is designed to fit the appropriate Kompact valve connection without custom fabrication.
Whether servicing a turbocharged Honda K20/K24, maintaining a B-Series forced-induction setup, or replacing a damaged outlet on an existing Kompact blow-off valve, the Turbosmart TS-0203-3004 Replacement Trumpet offers a straightforward and cost-effective repair solution.
Important: This product is a replacement trumpet only. It is not a complete blow-off valve and is not compatible with Turbosmart Kompact Shortie or compressor-cover-style valves using a three-bolt mounting flange.

Genuine Turbosmart Kompact Replacement Trumpet
The TS-0203-3004 is designed as a replacement outlet for compatible Turbosmart Kompact blow-off valves.
Rather than replacing an entire valve assembly when the outlet is damaged or missing, this component allows the original trumpet to be replaced individually.
Using a genuine Turbosmart replacement component helps maintain the intended outlet fitment and appearance.
Kompact Dual Port Compatibility
The Turbosmart Kompact Dual Port blow-off valve combines atmospheric discharge and recirculation functions.
During operation, the valve releases compressed air through its designated outlets.
The TS-0203-3004 replaces the trumpet-style atmospheric outlet on compatible valve assemblies.
This allows owners to restore the original discharge configuration when the existing trumpet is damaged or missing.
Kompact Plumb Back Compatibility
Turbosmart also lists the TS-0203-3004 as compatible with its Kompact Plumb Back valve range.
However, a Plumb Back blow-off valve normally returns discharged air to the turbocharger intake system rather than releasing it into the atmosphere.
Installing a trumpet outlet changes the intended discharge arrangement and may require additional configuration changes.
Before using this component on a Plumb Back valve, verify the exact valve model, outlet configuration, and engine management requirements.
Atmospheric Blow-Off Valve Discharge
A blow-off valve helps manage compressed intake air when the throttle closes.
During acceleration, the turbocharger produces compressed air that travels through the charge piping toward the engine.
When the throttle closes, pressure can accumulate between the compressor and throttle body.
The blow-off valve opens to relieve this excess pressure.
When configured for atmospheric discharge, the released air exits through the trumpet outlet.
This produces the recognizable blow-off valve discharge sound associated with many turbocharged performance vehicles.
Black Machined Aluminum Construction
The replacement trumpet features machined aluminum construction with a black finish.
Aluminum provides a lightweight and durable material for blow-off valve outlet components.
The black finish complements the appearance of compatible Turbosmart Kompact valve assemblies.
Replacement Trumpet vs. Complete Blow-Off Valve
Turbosmart TS-0203-3004 – Replacement Trumpet
Replacement outlet component only.
Compatible with specified Kompact valve assemblies.
Black finish.
Does not include the complete blow-off valve.
Intended for maintenance or outlet configuration changes where appropriate.
Complete Turbosmart Kompact Blow-Off Valve
Includes the main valve body.
Contains the internal valve mechanism.
Includes the appropriate actuator or control components.
Provides the complete pressure relief assembly.
Available in different application-specific configurations.
The TS-0203-3004 should be purchased when the existing valve is functional and only the compatible trumpet outlet requires replacement.
Important Kompact Shortie Exclusion
The TS-0203-3004 is not compatible with Turbosmart Kompact Shortie or compressor-cover-style blow-off valves that use a three-bolt mounting flange.
These valve designs use different mounting and outlet arrangements.
Always verify the exact Turbosmart valve model before ordering.
Vent-to-Atmosphere vs. Recirculated Air
Turbocharged engines may use either atmospheric or recirculated blow-off valve configurations.
Atmospheric Configuration
Releases compressed air directly into the atmosphere.
Produces an audible discharge sound.
Requires a compatible blow-off valve outlet.
Must be appropriate for the vehicle's engine management system.
Recirculated Configuration
Routes discharged air back into the turbocharger intake system.
Commonly used with factory mass airflow sensor arrangements.
Helps retain the original intake air metering configuration.
Requires suitable recirculation plumbing.
Changing from recirculated to atmospheric discharge can affect drivability on some mass airflow sensor-equipped vehicles.
The correct configuration should be selected according to the vehicle's engine management system and turbocharger plumbing.
Common Reasons for Replacement
Damaged Blow-Off Valve Trumpet: Replaces a cracked, bent, or otherwise damaged outlet.
Missing Outlet Component: Restores the trumpet on a compatible Kompact valve.
Blow-Off Valve Maintenance: Allows servicing without replacing the complete valve.
Restoring Original Appearance: Replaces a worn or cosmetically damaged trumpet.
Turbocharger System Reconfiguration: Supports appropriate outlet changes on compatible valves.
Replacing an Incorrect Outlet: Restores the intended trumpet-style fitting.
Used Blow-Off Valve Restoration: Replaces missing or damaged accessories.
Performance Engine Maintenance: Supports servicing of existing aftermarket blow-off valve systems.
Custom Turbocharger Builds: Provides a replacement outlet for compatible Kompact installations.
Preventative Maintenance: Replaces an outlet with damaged connection surfaces.
Installation Notes
Verify Blow-Off Valve Compatibility: Confirm that the existing valve is a compatible Turbosmart Kompact Dual Port or Plumb Back model.
Check for Shortie-Style Valves: Do not use this trumpet with three-bolt compressor-cover-style Kompact valves.
Review Turbosmart Instructions: Follow the appropriate installation or servicing documentation for the installed valve.
Allow the Engine to Cool: Avoid servicing turbocharger components while hot.
Locate the Blow-Off Valve: Identify the installed valve and its outlet arrangement.
Inspect the Existing Trumpet: Check for damage, looseness, or missing components.
Remove the Existing Outlet: Follow the correct procedure for the specific valve model.
Inspect the Connection: Check the mating surfaces and threads, where applicable, for damage.
Clean the Mounting Area: Remove debris or contamination before installing the replacement.
Install the Replacement Trumpet: Position the TS-0203-3004 correctly on the valve.
Secure the Outlet: Follow Turbosmart's installation recommendations without overtightening.
Verify Outlet Clearance: Ensure the trumpet does not interfere with nearby engine components.
Check the Discharge Path: Confirm that released air is directed away from sensitive components.
Inspect the Valve Assembly: Verify that the valve remains properly assembled.
Check for Pressure Leaks: Confirm that the outlet connection seals correctly when the valve is closed.
Verify Engine Management Compatibility: Ensure the intended atmospheric or recirculated configuration is appropriate for the vehicle.
Perform Controlled Initial Testing: Confirm normal blow-off valve operation.
Reinspect After Installation: Check for looseness, leakage, or interference.
Important: The replacement trumpet does not change the blow-off valve's internal spring pressure or repair a damaged internal valve mechanism. If the blow-off valve itself is malfunctioning, additional servicing or replacement may be required.
