This is our legendary classic Honda B-Series ProStreet turbo manifold, with a slight change to the WG routing to fit the 88-91 Civic EF chassis. This manifold is a staple in the EF tuning community and is a must for those seeking to extract maximum power from their setup.
Application Notes:
*Not AC compatible
*Must use 1/2 sized radiator, Full-Race EF radiator recommended
*Full-Race Traction bars highly recommended for all 88-91 Civics, in order to get proper downpipe clearance
*Must trim PS bracket in order to retain PS.
Features:
*The merge collector creates a turbulent free area for the exhaust gasses to enter the turbine housing in even pulses at high velocities.
*Robotic TIG welding for ultimate strength and longevity.
*Flange surfaces machined flat ensuring a perfect seal.
*ProStreet manifolds are CAD/CFD designed.
*ProStreet manifolds allow power-steering to run in conjunction with the manifold.
