Product Details
The Turbosmart Kompact 34mm Plumb Back Blow-Off Valve Fitting (TS-0203-3010) is a genuine Turbosmart replacement accessory designed for compatible Kompact Dual Port, Kompact Plumb Back, and Type 5 blow-off valves. Featuring a 34mm hose connection and black finish, this fitting provides a secure connection between the blow-off valve and the turbocharger intake recirculation plumbing.
Designed for turbocharged applications utilizing a recirculating blow-off valve configuration, the TS-0203-3010 allows discharged compressed air to be routed back into the intake system rather than released directly into the atmosphere.
Recirculating blow-off valve systems are particularly beneficial for vehicles equipped with mass airflow (MAF) sensors, where maintaining the intended airflow routing can help preserve consistent engine operation and drivability.
Manufactured to Turbosmart's quality standards, this replacement fitting provides the correct threaded connection for compatible blow-off valve assemblies. Its compact construction allows enthusiasts to replace a damaged or missing recirculation fitting without purchasing an entirely new blow-off valve.
The 34mm outlet accommodates appropriately sized recirculation hoses, making it suitable for custom turbocharger installations and existing systems utilizing compatible Turbosmart valves.
Whether restoring an existing blow-off valve, replacing a damaged outlet fitting, or configuring a turbocharged Honda K20/K24 for recirculated boost discharge, the Turbosmart TS-0203-3010 Kompact 34mm Plumb Back Fitting delivers genuine compatibility and dependable performance.
Important: This product is a replacement recirculation fitting only. It is not a complete blow-off valve.

34mm Plumb Back Connection
The TS-0203-3010 features a 34mm outlet designed for compatible recirculation hoses.
This connection allows discharged compressed air to travel from the blow-off valve back into the turbocharger intake system.
Correct hose sizing is essential for maintaining a secure connection and preventing pressure leaks.
Always verify the hose's inside diameter and the fitting's connection requirements before installation.
Kompact Dual Port Compatibility
The Turbosmart Kompact Dual Port blow-off valve combines atmospheric discharge and recirculation functions.
The TS-0203-3010 provides a replacement 34mm recirculation fitting for compatible Dual Port valve assemblies.
This allows owners to restore the original plumb back connection when the existing fitting is damaged or missing.
The fitting itself does not change the valve's internal operating characteristics.
Kompact Plumb Back Compatibility
Turbosmart Kompact Plumb Back valves are designed to recirculate discharged compressed air into the turbocharger intake system.
The TS-0203-3010 provides a replacement outlet connection for compatible 34mm recirculation plumbing.
Maintaining a properly sealed recirculation connection helps preserve the intended airflow path during blow-off valve operation.
Turbosmart Type 5 Compatibility
In addition to Kompact Dual Port and Plumb Back valves, Turbosmart identifies the TS-0203-3010 as compatible with its Type 5 blow-off valve range.
These valves share the appropriate standard fitting thread size.
This allows the 34mm plumb back fitting to be used with compatible Type 5 valve configurations.
Always confirm the exact valve model and intended outlet arrangement before ordering.
Recirculating Blow-Off Valve Operation
A blow-off valve helps relieve excess compressed intake air when the throttle closes.
During acceleration, the turbocharger supplies pressurized air through the intercooler piping toward the engine.
When the throttle closes, pressure can accumulate between the turbocharger compressor and throttle body.
The blow-off valve opens to release the excess pressure.
In a recirculating configuration, the discharged air is routed through the plumb back fitting and returned to the turbocharger intake system.
This helps reduce compressor surge while maintaining the intended intake airflow routing.
Benefits for MAF-Equipped Vehicles
Many factory turbocharged vehicles use a mass airflow sensor to measure incoming air.
On systems where the MAF sensor is positioned before the turbocharger, the ECU may already have accounted for air that passes through the sensor.
Releasing that measured air into the atmosphere can affect fueling behavior on some vehicles.
A properly configured recirculating blow-off valve returns the discharged air to the intake system, helping preserve the intended airflow arrangement.
Actual compatibility depends on the vehicle's engine management system and intake configuration.
Black Finish
The TS-0203-3010 features a black finish that complements compatible Turbosmart Kompact and Type 5 blow-off valves.
Its understated appearance helps maintain a clean, professional engine bay presentation.

Installation Notes
Verify Blow-Off Valve Compatibility: Confirm that the installed valve is a compatible Turbosmart Kompact Dual Port, Kompact Plumb Back, or Type 5 model.
Confirm Hose Diameter: Verify that the application requires a 34mm recirculation connection.
Review Turbosmart Instructions: Follow the installation procedure for the specific blow-off valve.
Allow the Engine to Cool: Avoid servicing turbocharger components while hot.
Locate the Blow-Off Valve: Identify the existing recirculation outlet.
Remove the Recirculation Hose: Carefully disconnect the hose from the existing fitting.
Inspect the Existing Connection: Check for damaged threads, seals, or mounting surfaces.
Remove the Original Fitting: Follow the appropriate Turbosmart servicing procedure.
Clean the Connection: Remove dirt and debris from the fitting port.
Inspect the Replacement Fitting: Confirm that the TS-0203-3010 is undamaged.
Install the New Fitting: Thread the replacement into the appropriate valve connection.
Avoid Cross-Threading: Start the fitting carefully and verify correct alignment.
Secure the Fitting: Follow Turbosmart's recommended installation procedure.
Inspect the Sealing Interface: Confirm that any required sealing components are correctly positioned.
Reconnect the Recirculation Hose: Install the compatible 34mm hose.
Secure the Hose Connection: Use an appropriate hose clamp or retaining method.
Verify Hose Routing: Ensure the recirculation hose is free from kinks and interference.
Inspect Nearby Components: Keep the hose clear of excessive heat and moving parts.
Perform a Boost Leak Test: Verify that the fitting and hose connection seal correctly.
Confirm Blow-Off Valve Operation: Check for proper operation during controlled testing.
Reinspect After Installation: Verify that the fitting and hose remain secure.
Important: The TS-0203-3010 is designed for the blow-off valve's recirculation outlet. It should not be confused with the 34mm inlet fitting, TS-0203-3007. Incorrect fitting selection can prevent proper installation or cause pressure leaks.
