S3 inlet manifold vs A3 inlet manifold

[stevegti2]

hi all does anyone know or has anyone flow tested the 2 in the past ? i have both for my engine and was wondering wich one to use .. both small port on small port motor

am fitting a t28 so all other plumbing will be new just wanted to know if there were any differences in the 2 inlet manifolds i noticed they are different shaped plenums but nothing major jumped at me


all info appreciated

thanks

If both are smallport then they should flow virtualy the same, the only difference im aware of is the tb position, no if it was a agu inlet then that would outflow the s3 one.
