AC Tuning Mazda MX5 1.8 mk2 / 2.5 turbo manifold with T25 flange.
Our manifolds are built from back purged 1.5" stainless schedule nominal tube providing superior flow and strength.
We can offer the same design with 1.25" runners if required.
We have used one of our manifolds on our own mk2.5 mx5 turbo which produced a reliable 257hp 232ft/lb at 1 bar of peak boost.
