The cast manifolds, the metal ones that say EFI on them, is the one from the 1.8 any different to the one on the 1.6? also what is the difference between the 130 spec and the normal 1.8 one? any help would be greatly appreciated.

 

The RS1800 inlet has slightly bigger ports and is the one to use if you are keeping the original EFI.

 

is the standard 1.8 manifold an upgrade over the 1.6 one?

130 spec ones are a littlehard to come by and expensive at the minute, money is tight.

 

I think they are the same. Some normal escorts had the 130 bhp spec engine so it's worth chekcign engine numbers etc to see if you can fin one.
