Please allow 3-4 weeks build time.  For the ultimate in spool up and power, look no further than our divided collector header for split scroll turbine housing turbos. Primaries 1&4 and 2&3 are paired to promote even cylinder firing pulses to the collector to not only increase turbine efficiency but reduce reversion back into your engine, further increasing power output. Dramatically reduced spool time. Designed to fit Turbocoupes, SVO mustangs, Merkur XR4TI's and pinto applications. Accepts 38mm Tial V-band wastegates (2 required). Expect 3-4 week build time and select options below before placing order.
