Right, as far as I know, the shafts and mounts are the same with both engines.

For the conversion, I would need the engine loom, ecu, fuel pump and the end of the fuel lines?

Im clueless on engine wiring, what would need changed/wired in? Any guides for it?

You sure the loom will plug right in? Going from single point to multi point, im not so sure.

DYL, are you thinking of the 1.4 8v SPI? 60BHP, SRI MPI is 82bhp iirc

Though it was F10s in the 1.2 8v? F13 in the 1.4 8v MPI, F15's in the 16v's?

if you've got a multi plug on your engine loom, you'd just need to unplug that and plug the new loom in, I think.

Christ, im not sure at all, will have a look tomorrow. Will be handy if it is though. So if it is, just swap the loom and ecu around, and thats it? Il be able to do it myself if so

Not true.

My 16v had an F13, not an F15.

Early 1.2s had F10s, but later ones had F13s.
