Hi Bruce
I would think it's a Metro 1.4 GTI donor. I originally built my car with a 1992 1.4 MPI GTI donor [see photo].Looks pretty much the same. Same fuel filter, coil, plug leads, inlet manifold, can't see the ECU though. I can see you have a 1.4 gear change so it will be a 1.4 [R65] gearbox. Have you still got a cable clutch, if so you might want to have a spare made or convert to hydraulic.
I can let you have the chassis no from my donor if you need a chassis no. to get any spare parts.
Bob.
