Can a EFI CVH inlet manifold with XR2i/Fiesta RST throttle body (including Throttle Position Sensor).
enable you to convert your S1 or S2 Escort RS Turbo to run either Cosworth or Fiesta RS Turbo EFI engine management, or would it need to be the FRST one used.
Many thanks - Dave

 

I butchered an XR2i inlet to use with my Omex. As far as I know the XR2i and FRST ones are the same.

 

XR2i, FRST and the Onion i Ghia/XR3i EFi all use the same inlet and throttle body. Only difference is the addition of a 2mm hole in the throttle butterfly on the Hitachi ISCV equipped cars (XR). It's a wee bit more envolved than just changing the inlet and throttle body though
