Your going about this backwards. The Aygo engines weighs in at 70kgs and a 2.0 Zetec comes in at 115 Kgs. So your 69Bhp car at 500 kgs will be 138bhp/Tonne. But the Zetec, producing 140Bhp comes in at 545 kgs, giving 256Bhp/Tonne.
Your engine of choice, not only being almost impossible to engineer into the car, is going to give some mediocre performance compared to a FWD Mondeo engine. There are loads of RWD gearbox / engine combinations out there, why don't you benefit from all the engineering and money car manufacturers have spent with engines and gearboxes and choose a combination to suit you.
