Hi what is a good single Turbo manifold for a 93 rx7 I looked at the SDR manifold because it has shorter runners and I heard they are a good quality manifold any suggestion on the manifolds also I'm looking to get around 500hp as a street car.
Thanks

 

There are a few companies out there, I had the Turblown dual Wastegate manifold on my old setup and totally recommend them I got 592hp without any problems, quality and fitment without any issues, plus great costumer service.
