Turbo Exhaust Manifolds

BLOX Racing’s entry into the turbo manifold market is marked by three, popular Honda designs and one Subaru “Big Tube” high performance replacement unit.

BLOX Racing’s initial release of turbo manifolds will be available for Honda B-series and K-series engines and will feature a unique dual-pattern turbo inlet flange. This industry-first will give the customer the choice of starting with a T3 turbo and later upgrading to a T4 without having to purchase a brand new manifold. Each manifold also features a V-band wastegate flange that will accommodate 44mm, 45mm and 46mm sizes from most popular brands.

Manifolds are constructed from Schedule 40 T304 stainless steel and TIG-welded.  The 11mm thick flanges provide additional strength and rigidity.  The 4-1 design provides equal pressures across each cylinder to ensure maximum flow and quicker spooling for larger turbos.  With this design, the turbo and related parts are easily accessible.

 

BLOX Racing’s Big Tube turbo manifold will be available for Subaru Impreza WRX FA20DIT.  This high performance replacement features larger tubing than all other competing brands in the market.

The FA20DIT Big Tube Manifold features 45mm piping from start to end and 11mm thick flanges.  The ports have also been opened up to 41mm at the head flanges and 36mm at the turbo flange.  In addition to the “big tube” manifold primaries, the larger port diameters allow for greater flow and power production from the OE turbo or similar size aftermarket unit.
