Turbosmart Wastegate Boost Controller New Lineup: What You Need to Know

Gen-V Race Port Wastegate Updates

The biggest news in Turbosmart's 2026 wastegate boost controller lineup is the Gen-V Race Port series getting a complete refresh. The new TS-0555-1014 (38mm) and TS-0555-1015 (45mm) models now come standard with 14psi actuator springs instead of the previous 7psi baseline.

This change makes sense for modern turbo setups. Most built engines run 15-25psi daily, so starting with a 14psi spring means less shimming and more consistent boost control right out of the box. The diaphragm material has also been upgraded to handle higher boost spikes without tearing - something the previous generation struggled with on aggressive tunes.

Flow capacity remains the same at 1,200 CFM for the 45mm and 900 CFM for the 38mm, but the valve seat now uses a harder tungsten alloy that should last longer under high-temperature exhaust conditions.

New ProGate50 Series Features

The ProGate50 series is Turbosmart's answer to the growing 50mm wastegate market. The TS-0555-1050 ProGate50 pumps out 1,500 CFM flow capacity and comes with their new quick-change actuator system.

Instead of unbolting the entire actuator assembly for spring changes, you can now swap springs in about 10 minutes using the included tool. Spring options range from 7psi to 21psi in 7psi increments. The actuator rod is also adjustable without removing the wastegate from the manifold - finally.

Build quality feels solid. The cast body uses the same 316 stainless steel as their high-end race gates, and the flapper valve is laser-cut for consistent sealing. Installation uses standard V-band clamps, so it'll drop into most 50mm wastegate setups without modification.

Updated Boost Control Solenoids

Turbosmart updated their boost control solenoid lineup with the new Dual Stage and Race Port solenoids. The TS-0103-1001 Dual Stage now flows 35% more air than the previous version, which translates to faster boost response on larger turbo setups.

The internal valve design switched from a simple ball valve to a staged poppet system. This gives better flow control at partial throttle and more aggressive boost ramping when you're on it. It's also less likely to stick when running methanol injection or other corrosive fuels.

For ECU integration, all new solenoids use a 12V PWM signal with 100Hz frequency. They'll work with most aftermarket ECUs without additional controllers, though you'll want to verify compatibility with your specific tune setup.

Application Compatibility

The new lineup maintains backward compatibility with existing Turbosmart mounting hardware. If you're running current Gen-IV wastegates, the actuator assemblies are interchangeable, so you can upgrade just the control components without replacing the entire wastegate.

For popular platforms, the 38mm Race Port works well on stock-location turbos for Subaru EJ/FA engines, Mitsubishi 4G63, and Honda K-series builds. The 45mm handles most external wastegate applications up to about 600hp. The new ProGate50 is sized for serious builds - think 700hp+ or twin-turbo applications.

Spring rate selection depends on your target boost pressure. Run about 70% of your target boost as your spring rate. So for 20psi target boost, use a 14psi spring. This gives the ECU enough control authority without fighting the spring pressure.

Frequently Asked Questions

What's different about the 2026 Turbosmart wastegate lineup?

The 2026 lineup features standardized 14psi springs, improved diaphragm materials, new ProGate50 series with quick-change actuators, and updated boost solenoids with 35% better flow rates.

Do I need to upgrade from my current Turbosmart wastegate?

If your current setup is working reliably, there's no urgent need to upgrade. The improvements are evolutionary rather than revolutionary. Consider upgrading if you're having boost control issues or building a new setup.

Will these work with my existing boost controller?

Yes, all mechanical components use standard vacuum connections and mounting hardware. The new solenoids use 12V PWM signals that work with most aftermarket ECUs and standalone boost controllers.

What spring rate should I run for my boost target?

Use approximately 70% of your target boost pressure as your spring rate. For 18psi target boost, run a 14psi spring. This gives proper control authority without over-springing the system.
