SpeedFactory Racing B / D-Series Bottom Mount Turbo Manifolds
CURRENT ESTIMATED MANIFOLD MANUFACTURING TIME IS 3-6 WEEKS.
The SpeedFactory Racing Bottom Mount Turbo Manifold has a near-equal length design and spools medium to larger turbos very quickly, producing broad powerbands that carry to the top of the RPM range. This manifold is for medium to high power applications where large torque and great spool are necessary alongside big top-end horsepower, making it suitable for road race and drag race vehicles.
These manifolds are constructed from high quality 1.5” Schedule 40 stainless steel, and is TIG-Welded and back purged to ensure that you are receiving the highest quality product possible. Our cylinder head, wastegate, and turbine inlet flanges are CNC machined from ½” plate 1018 Steel and all mating surfaces are machined flat ensuring a perfect seal.
