If this is the rear wheel drive version I think the engine and gearbox could be made to fit but the back axle is a live axle. You could get round this by using the Ron Champion Locost book or by using the rear of the Locost chassis on a Roadster frame. The front hubs are unsuitable so you'd have to source some Cortina hubs (Locost) or Sierra hubs (Roadster).
If it's the front wheel drive version you'd need to source a gearbox too - probably not worth the hassle. It's pretty confusing, using two different drive trains in the same body!
