Hi all.
Does anyone know if a new blacktop zetec engine would be a straight swap for an earlier silvertop zetec? I have used 2 doner vehicles for my build, a sierra donated it's gearbox,rear diff drive shafts and brake back plates, and a orion donated it's engine a 1.8 silvertop zetec.Because I used 2 doner vehicles I've been told I'll get a Q plate, unless that is I swap out the engine and use a brand new one. I know I'll need a new exhaust with a cat fitted but would I be able to use everything from the silvertop? Or grin and bear it,save my dosh and get a Q plate.
