as far as i'm aware all mk4 shafts are the same fitment/strength. I'm using 1.3 ones in mine above and never misses a beat.

I'm running a XR3i efi tank with pump inside and have mounted filter here:



not sure about the plastic manifolds, i know the mondeo ones dont fit at all. Think the Escort GTi will fit but better off using the metal inlet like mine above if you can get one.
