BLOX Racing’s Top Mount manifold (featured here) is available for Honda B-series engines and features 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.

The 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.
