InlinePRO T4 Turbo Manifold for Honda & Acura B Series Engines

InlinePRO T4 Turbo Manifold for Honda & Acura B Series Engines InlinePRO is the only company to manufacture a true cast stainless steel manifold. Using stainless steel allows for longevity and larger runners because of the strength of stainless steel. Although some may call this manifold a "log" manifold, it is NOT a true log design. Each runner has a specific design to centralize the wastegate position to maximize flow and allow a steady boost curve. With this wastegate position and runner design, boost creep is kept to a minimum as well. This manifold can accept a turbo as big as a GT42R/S375 with the proper tuning and engine setup a GT42R can create over 850whp with this manifold design. Mat Keller was able to run in the 9.30's in 2007.
