Why TiAL Sport MVR Wastegate?

Performance:

The MVR’s optimized actuator-to-valve ratio ensures precise boost control across a wide range of pressures (4.35 PSI to 24.66 PSI with included springs), preventing overboost and protecting your turbocharger. Its 44mm valve delivers exceptional flow capacity, outperforming other 44mm and 46mm wastegates in the market.

Compact and Versatile Design:

At just 4.17” tall, the MVR’s ultra-compact footprint fits in tight engine bays, making it ideal for custom turbo setups. With two top air ports and three bottom air ports, installation is a breeze—no need to rotate the actuator housing.

Advanced Cooling Technology: Integrated -4AN water-cooling ports (removable if not needed) cycle coolant through the actuator to maintain optimal temperatures during extreme conditions like road racing or high-heat dyno sessions, a feature not found in most competing wastegates.

Race-Proven Durability: Constructed with a high-temp NiCrFe-based alloy valve, 347SS valve housing, and Nitronic 60 stainless steel valve seat and bushing, the MVR resists corrosion, wear, and galling, even when running leaded racing fuels. The 17-7 PH stainless steel actuator spring maintains consistent pressure up to 900°F (483°C), ensuring long-term reliability.

Stunning Aesthetics: The vibrant purple anodized aluminum actuator adds a bold, custom touch to your engine bay, combining form with function.

Made in the USA: TiAL Sport’s commitment to quality shines through in this American-made product, backed by decades of motorsport heritage and engineering excellence.

Vehicle Fitment Data

The TiAL Sport MVR Wastegate is a non-application-specific component designed for universal fitment on turbocharged vehicles with custom or aftermarket turbo setups. It is particularly suited for larger turbochargers, such as those from Garrett, Precision, or BorgWarner, commonly found in high-performance applications. Below are examples of vehicles and setups where the MVR is a popular choice.

• Subaru WRX/STI (2002–2025): Compatible with aftermarket turbo kits (e.g., Garrett GT3076R, Precision 6266) and custom exhaust manifolds.
• Mitsubishi Lancer Evolution (1992–2016): Ideal for upgraded turbo setups on 4G63T engines.
• Nissan 240SX/Silvia (1989–2002): Perfect for SR20DET or KA24DET builds with external wastegate provisions.
• Toyota Supra (1993–2002): Suits 2JZ-GTE engines with single or twin-turbo conversions.
• Honda Civic/Integra (1988–2025): Fits B-Series, K-Series, or H-Series engines with custom turbo manifolds.
• Ford Mustang (1994–2025): Compatible with Coyote or Ecoboost engines running aftermarket turbo kits.
• BMW 3-Series (1990–2025): Works with N54, N55, or B58 engines in custom turbo applications.
• Universal Applications: Any vehicle with a turbocharged engine and a manifold designed for a 44mm V-band wastegate (e.g., Mazda RX-7, Audi S4, VW Golf R, etc.).

Note: Fitment requires a compatible turbo manifold with a 44mm V-band wastegate flange. Professional installation and tuning are recommended. May require modifications for proper integration. Not CARB legal not for sale in California.
