Hi, i recently put a punto 60 engine into my mk2 uno. I rebuilt the engine, new main and big end shells, new piston rings full gasket set and had the crank, pistons, conrods and flywheel lightened and balanced.

I'm still running all of the uno ignition and fueling though. It works great and pulls well but i really want to use the tricker throttle body i've got sitting under the bed and i don't want to butcher the 1.0 wiring loom incase someone else needs it.

Is it simply get the wiring loom from a mk1 8v punto, get any ecu from a pu to 55/60 or seicento/sporting. Use a mckritch chip or the same chip but cheaper in the seicento classifieds and thats it?

The uno system doesn't use a map sensor, doesn't have a crank or cam sensor.

I have the crank pully with the notches so i can just put that on and get a punto alternator as the belts differ between puntos and unos.

Will i need to get the twin coils and as well? I don't know if the puntos system soes fueling and ignition or if it is split like the unos as the uno ignition is done by a distributor.

Thanks
Dan

Good luck with your project. I have attempted this two or three times but have been unable to complete the conversion due to the Punto MK2 ECU not playing nice. I couldn't get the immobiliser to disengage. I think the MK1 Punto bits might be the way to go for this conversion.

Have a look at my thread here:

You might pickup on a few things you haven't thought about as I've got pictures on there.

Was busy at work when I posted earlier. A few issues you'll need to consider when doing a conversion of this nature:

1. The mounting bracket for the metal water pipe is in a different place so it can't be secured properly without work.
2. On the P60 cylinder head I was using their was no provision for the temperature sensor so my engine temperature gauge wouldn't work.
3. Starter motor was a little different and although it did work it couldn't be secured properly using all 3 bolts. In fact I tried and I broke the casing.

There was a number of niggles over and above like cam pulley etc. I think on it and post some more later.
