Featured below is the SUPERCIRCUIT turbo manifold developed for the Subaru WRX (VA) FA20 engine. This model is the first of the WRX line to deviate from the EJ-series engine. It uses the new 2.0-liter FA20F engine, which has direct injection and a twin-scroll turbocharger.

The SUPERCIRCUIT Subaru WRX (VA) FA20 turbo manifold is made with larger bore grade 304 mandrel bent stainless steel pipes to minimize the restriction for better exhaust flow efficiency and is fully TIG/Argon welded on stainless steel flanges for long lasting performance and durability!

On all previous Subaru WRXs (with the EJ-series engine), the turbocharger was located near the right-hand side of the firewall, close to the third cylinder. With the new FA20 engine, Subaru fitted the turbocharger at the front of the car, close to the serpentine accessory belts.
