MANIFOLD ADAPTORS (Inlet & Exhaust)Inlet manifold adaptors
If you want to use a different inlet or exhaust manifold on your engine, then these plates will allow easy fitment.  The following items are on file and available within a couple of days, but most combinations can be catered for.  Just find an easily available turbo exhaust manifold from an engine that has similar port shapes & spacing, send us both manifold gaskets, and we'll make a plate that will get you halfway towards a turbo conversion without the need for a custom manifold.

Zetec head - CVH exhaust manifold adaptor, allows the RS Turbo exhaust manifold to be fitted directly to a Zetec head,
Zetec head - CVH inlet manifold adaptor, allows the Efi or carb inlet manifold from the CVH to be fitted directly to a Zetec head, (see photo bottom left)
Zetec head - Rover "T" series inlet manifold adaptor
CVH head (Mfi or carb) - Rover "T" series inlet adaptor plate
CVH Efi head - CVH Mfi/carb (or vice versa) inlet adaptor plate, to correct the mis-match of port shapes
CVH EFi plenum vertical spacer, adds 13mm clearance over rocker cover, (see photo bottom left)
YB Cosworth inlet plenum spacer, creates extra space around the trumpets by moving the inner plenum wall further away from the bellmouth,

Some of these items can be ordered online - here.

This type of specially machined plate can also be used as the starting point for a custom inlet manifold or plenum - basic drawings and a gasket are often all the info needed.  Some customers have removed the flange from their chosen manifold & welded it onto the new plate, or we can machine a counterbore (round or oval) to allow easy location & welding of your inlet tubing.  Once the manifold is finished, consider using a Thermal Inlet Gasket or Exhaust Plate to reduce heat soak - more details here.
