Q I’ve got a Mk2 Cortina with a Granada 2.8i engine, which is good fun but I’d like more. I’m in the process of sourcing a Granada Cosworth for a donor and I was wondering if it’s possible to convert my car to Sierra 4x4 running gear?
I would like to do as little fabrication work as possible so was wondering if there was a suitable back axle that would work with the MT75 front ratio? What sort of changes are needed at the front? Is this a viable project, as I haven’t seen any 4x4 Cortinas? Adam Palmer Email
A Of course this is possible, but at what cost? For conversions of this type, a lot of people use the complete Sierra 4x4 floorpan, cut out from the donor car, and then modify it to fit in place of the existing floor of the project car. It’s a mammoth task and will stretch the most experienced welder and fabricator’s skills to the limit. Unless you’ve got the required expertise, the time and the money, it’s best left alone.
In comparison, the 24-valve conversion is relatively straightforward, especially as you already have the Cologne engine fitted — and it’ll be a lot more fun in a two-wheel-drive car.
