2 of my mates have 24v sierra's, 1st is an XR4i with 24v lump & the other bought a 1.6L 3dr with a cossie kit on it that was already fitted with a 12v 2.8 engine, he bought a granada 24v for I think about £600 & swapped all the bits over, both of them seem to rate the engine but its not my cuppa tea.

Cheers Simon.
