Finally a turbo manifold that will flow as much as a tubular manifold but cast to prevent the cracking associated with tubular manifolds. These manifolds are a MUST for turbos like the JWT 700bb, Z1 GT675RS, and the new Z1 GT725R, and are an excellent companion to our new GT535 turbos as well. They bolt up just like the stock 300zx cast manifolds(EGR is eliminated) and will fit all turbos made for the Z32 T2 flange.
