LS Turbo T4 Manifold Silverado/Sierra

  • Regular price $650.00


GM Truck 99-up turbo manifold.  This thick wall cast stainless steel swept runner manifold is the same one we use in all our kits starting in early 2013. Manifold is plenty strong to hold up even to the most demanding conditions. Runners are swept and opened to maximize the flow from each runner.  Provisions for a 2 bolt waste gate are built right into the front side of the manifold.  This is the last point before the turbo. The T4 turbo mount is a TRUE T4 opening, not a T4 flange with a 2.5" hole cut into it.  This maximizes the flow leaving the manfiold, by getting rid of any transtion inside the manifold. The T4 flange, crossover flange and gate flanges are drilled and tapped for studs.   Originally designed to fit 99 and up GM trucks, it may be used in other applications.  Fits LS style heads. Manifold comes with studs,nuts for the turbo and the crossover flange.  Crossover flanges, Gate block plate and hardware can be added to your purchase.. Gaskets are avialable for an added cost.

Wanting to build your own turbo kit.  This manifold is a HUGE part of the puzzle and now its CASTED.
