Engine age emissions question

[deezee]

I've been reading the Feb issue of Kitcar, and they have some great info on the SVA in there. However, they include a little bit about emissions testing, and say any engine after 1992, or of an unknown age, has to go through a CAT test.

This has really bummed me out, as I had been hoping to use a sierra donor for most of the car, but powered by the lighter zetec 1.8 engine in my build. The only zetec engines I can get hold of are all mid 90's or later.

Sooooo does this mean, I'd have to keep the cat and all the other junk on the engine? Or would I be able to 'loose' all my documents and pop it through as a Q reg? Or does the Q reg, visual smoke test no longer apply on a IVA? TIA
