Our cast manifold offers a simple solution to allow a big turbo upgrade to be fitted to a Mk2 Focus ST & RS five-cylinder engine (also compatible with Volvo C30 T5 engine).

We developed this design several years ago and it has since proven time and time again to be both a reliable and free-flowing manifold, thanks to its heavy duty construction which ensures it will not crack over time, regardless of the amount of heat cycles.

It’s also proven to flow to 550bhp with no issues and features a T3 flange, making it compatible with a huge range of turbos, including the popular GT30/GTX range (with T3 four-bolt flange fittings).

There’s also an external wastegate flange suitable for a 38mm Tial wastegate (or similar size two bolt fitting), or alternatively, this can be blocked off to suit internally gated turbos.

We also offer the option to add our matching 3″ downpipe, which is constructed in stainless-steel, features an external wastegate vent pipe that goes back into the downpipe for reduced sound, and matches up to any aftermarket exhaust system and in doing so, offers a simple solution for a bolt-on upgrade.
