Hello all,
As my Vito 113 Petrol M111 Engine is tapping and "whirring" away.

Its going to need some major "spanner waiving".
what are the prospects for an engine change in this vehicle, it has LPG plumbed in too, and the running costs are not a concern. Can the cosworth Motors be used in transverse configurations? Also does the VW VR6 engine bolt into these chassis (I heard a rumour). What about a bigger displacement M111, or even a

supercharger unit?
I have about £1500 to spend on this project so finding a good used power plant should be within budget.
Many thanks for thoughts, offers, and suggestions.
