i want to turn my 1.0 fiat uno fire 1992 to a 1.3 mk1 turbo engine i have found a engine but i want it fitting. do any modifications need to be done to fit this engine or is it just plug and play i also want to know about how much it would cost to get it fitted
No disrespect, but if you need to ask questions like those then you really haven't grasped just how much is required to do the conversion. You need much, much more than just a turbo engine to convert a 1.0 Uno into a 1.3 turbo. Bear in mind there are differences between mk1 and mk2 turbo engines so you would run into issues using a mk2 Uno with a mk1 turbo system. It can be done but it will need a lot of work.
First thing I would suggest is if you haven't got one already then buy yourself a Haynes workshop manual. Then read the entire supplement section covering the turbo model, including the wiring diagrams, which will then give you an idea of what is involved with the turbo versions.
You will need all the following from a turbo Uno to convert yours: engine, gearbox, exhaust system, gear linkages, turbocharger, intercooler, oil cooler, radiator + fan, wiring loom, ecu's, cooling system, engine/ gearbox mounts. You will also need the wiring loom under the dashboard, fusebox, additional relays, fuel tank, fuel pump, fuel lines and the turbo instrument cluster. Then you will need the entire braking system, suspension, rear beam axle with disc brakes, front anti-roll bar, struts, shocks and springs, braking system including servo and master cylinder, wheels/ tyres.
The above is not an all inclusive list so there well may be more parts you would need to make the conversion work. It also doesn't include the interior and exterior body/ trim parts that you will also need to do the full conversion.
Sorry to rain on your plans, but better to know exactly what's involved than to buy an engine thinking that's all you need. If you do still want to go and do this conversion then plan well ahead, gather the parts required and get cracking! You will also find people on here that can help you with any queries that arise so feel free to ask away.
Good luck!
