It
should be SVA'd , as it will be a radically altered monocoque which will then result in a Q plate.
But as above just notify engine change and see what happens.
My Focus V.5 says 5000cc as the engine size.
If EITHER the engine or the Shell are pre 93 then no CAT test.
Mine is year 2000 shell with 1988 engine = no CAT test.
