I believe that the VW 1.2 and 1.4 TDis are 3-cylinders, if you can find any. No idea what the external dimensions are, don't forget to take into account the extra size of the turbo gubbins. To be honest though, I'd rather use the Metro engine. I'm assuming that you'll be travelling relatively short distances in stop-start conditions, in which a diesel has very little advantage over a petrol engine. The extra weight of a diesel engine (not to mention that of the turbo) will be a severely limiting factor in such a small vehicle.
On a total cost basis, if my assumptions are correct (feel free to pull me up if they're not), the Metro engine will be the more economical choice.
