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

 

as far as im aware the xr2i inlet and fiesta turbo inlet manifolds are the same

 

Everything is the same (XR2i vs. FRST) for except the loom, ecu, map-sensor and inlet air sensor.
Of course I'd always advice to use a completely different management...
