hi, does anyone know if it is possible to put a 1.4ie mono jetronic engine in a 999c fire uno, what would need to be transferred from donor car, is 5 door uno basic same chassis as 3dr, except for doors, thanks

Yes, yes and yes.

You need all the mounting parts, engine loom, exhaust, gearbox and driveshafts etc. from the 1.4 as well as the FIRE installation is different.

The chassis is the same whether 3 door or 5 door.

thanks for reply, does it matter if 999c uno has fuel carburettor not electronic injection and donor car has, will the fuel tank out of 1.4ie fit in 999c uno as i think the fuel tanks are different, shape and design , any thoughts anyone...
 
You would need to replace fuel tank and fuel lines.

I would rather fit 1.6 carbed engine from Tipo. Easyer to fit than IE, more HP
 
wouldn't the 1.6 tipo carb engine be too heavy, what about the 1.4 tipo carb engine is there such a model, would this work with the existing fuel tank, and would the drivetrain fit to the uno hubs, thanks

A 1.6 Tipo engine is the same basic block and design as the 1.4 version. The weight difference would be almost non existant.

Yes, there was a 1.4 Tipo carburettor model though I think they were the pre-facelift versions only. As such they're old and getting hard to find.

What you really need is to find a mk2 Uno 70SX or 1.4 i.e as that will come with all the parts you need to swap over. The FIRE gearbox is not compatible with the 1.4 Uno/ Tipo engine for instance so you need the 1.4/ 1.6 Uno/ Tipo box. I'm not sure on the driveshafts but I *think* they may be the same as the FIRE models.

Another option you can consider is to fit a bigger FIRE. Advantages are a lighter engine, more modern and in 1242 16v guise it will give good power as standard.

Check out Panda Sport's 16v Classic Panda guide to see how it was done. To do it to a Uno would be very similar.

There is also 1.6 90HP MPI engine from Tempra, it has same block as 1.4, so there is no difference in weight, but it has 20HP more. If you won't fit cat it would have even more. Maybe also Brava/Bravo 1.6 16V 105HP fits to 1.4 gearbox, but I'm not sure​

On a typical 3L engine , the power lost due to flow restriction through a cat converter is less than 5HP.
In a small engined car , its likely to be a lot , lot less.


My recommendation is to leave the converter working and in place especially if it is a requirement under law in your state or territory.

I remember when catalytic converter cars became compulsory in the UK. One of the car mags took a crossover year car (same model available both pre and post cats) the Peugeot 205 GTi, and tested it both with and without cats. The cat equipped car had decreases in both top speed and acceleration, and fuel consumption increased. This was due to the compulsion to use unleaded fuel and having the ignition timing retarded to suit as well as the extra restriction caused by the cat itself. I forget the difference in power but I remember the mag also reported that the cat equipped car felt more rough and less responsive.

A Uno manufactured before January 1st 1993 is not required to have a cat fitted. Thus when I fit the MPi 1242 FIRE lump to my 1986 45S I will not be fitting it with a cat equipped exhaust. I may get a very small gain in power, but I will also remove a part that costs a sizeable amount to replace as well as making the exhaust system less complex. The car will still pass all emission requirements as it's the car's year of manufacture that determines its emission requirements and not the engine fitted.

If my Uno were post January 1993 I would have no choice but to fit a catalytic converter unless the engine was in such good shape it would meet the more stringent emission requirements without one.
