Flange Header Manifold for Scion xB (2008-2015) 2.4L DOHC Turbo Engine

High-Flow T3/T4 Turbo Manifold for Toyota & Scion 2AZ-FE 2.4L

Who Is This For? Designed specifically for Scion and Toyota owners running the 2AZ-FE 2.4L engine who are ready to transition from a naturally aspirated setup to a high-performance turbocharger configuration for street or track use.

The Naturally Aspirated Ceiling: You step on the gas in your [Engine Name] and the power delivery feels linear but limited. The restrictive factory cast manifold was designed for fuel economy and quiet operation, not for the high-exhaust velocities required for forced induction. Forcing boost through a stock or generic log-style manifold creates massive backpressure and heat soak, which can lead to manifold cracking and a significant loss in potential horsepower.

The Engineering Solution: We engineered this T3/T4 Flange Turbo Manifold to unlock the true potential of the 2AZ-FE platform. By utilizing CNC-machined mandrel-bended piping and TIG-welded T-304 stainless steel, this manifold provides a smooth, high-velocity path for exhaust gases to reach your turbocharger. It features a dedicated 35mm/38mm external wastegate flange, allowing for precise boost control that internal wastegate setups simply cannot match.

The Comparative Edge: Why This Beats the Competition

• Maximum Flow Efficiency: Features a standard T3 & T3/T4 hybrid turbo flange, optimized for the most popular aftermarket turbochargers to deliver immediate spool-up and top-end power.
• Premium Metallurgy: Constructed from T-304 polished stainless steel, which offers superior heat resistance and structural integrity compared to cheaper aluminized or T409 steel that often warps under the extreme temperatures of a turbo system.
• Structural Durability: TIG-welded flanges and mandrel-bent tubing ensure a leak-free seal and resistance against the vibration-induced cracking common in lower-quality aftermarket manifolds.
