Hi,

I have a little fiat uno 1.1ieS with tinted windows sound system with subs and amp, mp3 head unit, a few interior mods, on the engine I have got a custom manifold and free flow exhaust and a K&N air filter, its also got tinted windows and 15" rims with 195/50/15 rubber. What mods do you think I should do next, I would like some more power out the engine...anyone know if it is worth while considering a transplant of a 1600 engine form a honda or toyota?

Has anyone got the specs on the 1,1ies engine, I would like to know how much horse power ect.

Thanks
David

Hello and welcome to Fiat Forum onto he Uno....

....sell it and buy an Uno Turbo

Shove some pics up so we can see. There is so much that can be done depending on budget and personal taste. I personally like to keep things conservative and generally minor enhancements like lowering and uprated brakes on the original spec.

Welcome to Uno-land David!

Well, from memory the 1.1 engine produces about 55bhp, possibly a bit less. An easy swap is to drop in the Punto 1242cc FIRE engine, which though it only has 60bhp the torque is quite a bit more making for a nice drive.

If you want real power, fit a Uno turbo lump as Pottleflump suggests. Fitting another manufacturers engine will be expensive as you will need custom fabricated parts to make it fit. It can be done, but unless you have lots of money or extensive know how I wouldn't even attempt it.

The only other mods I'd suggest would be to fit the bumpers and sideskirts from a turbo. Uno's look good when clean and subtle, clutter them up with Max Power add ons and they tend to look :yuck:

But it's all down to taste, so it's up to you what you should do next!

Thanks for the help Pics on the way :slayer: maybe you will have some suggestions once you see them..

Is their a bigger fiat engine that I could fit in the uno than the punto engine?

Welcome David,

Yes, there is a bigger engine - 1580cc used in the Tipo, which responds well to modifications if available (same engine type as the older X1/9 so there may be carburettors/camshafts around). This is also almost the same engine type as the 1372cc unit fitted to the five-door Uno (Pacer in S.A.?) and so you can get the mountings, gearbox etc. from one of those.

The 1242cc engine that 1986Uno45S refers to actually comes in a couple of states of tune - the more recent 16v version is 85bhp which would be a useful increase. These were/are fitted to a few current FIAT models (Punto, Palio?) which may or may not be readily available, but I think the engine should marry up to your existing FIRE engine mountings & gearbox.

Actually the 1108cc has a whole 58bhp... unless the injected version has less power than the carburettor version! Which, I think - it might do, so Chas (1986Uno45S) is probably right after all.

I also agree with thepottleflump in that the best value is going to be in buying an Uno Turbo, transferring your modifications to it, and selling your car... There are some truly great Uno Turbos in South Africa and they were made there until about 2000 so they're in better condition than elsewhere in the world!

Cheers,
-Alex

That is very true Alex, but the reason I only mentioned the 60 engine was that it is a nearly straight swap being an SPI like the Uno 1.1. The 75 engine and 85 engines will physically swap in no problems using the Uno mounts and existing gearbox, BUT, both use MPI fueling meaning a whole load of extra changes to make to the fuel system and wiring.

I've often thought that the 85 16v engine would make a nice swap, and would also make a Uno quite quick considering that the mk1 turbo only made 105bhp (if left as standard!)

So 60 engine is an easy swap, though with more work the 75 and 85 Punto engines will also go in. I wonder which one I will go for when I finally get round to upgrading the engine on mine...:chin: :devil:

The easiest mod I think would be to fit the 1498cc engine, mated to an uno turbo gearbox and driveshafts (and brakes and uprated suspension to keep it safe) The 1498cc engine can come from a fiat x1/9 or strada 75/85, and will fit straight in the engine bay using the uno turbo engine mounts. The other advantage is that you will not need to mess around swapping wiring looms/dealing with injection/diffrent petrol tank etc etc. I have done this already on my uno circuit racing car! Fit a piper 285 cam and single twin choke carb, and you are at 100bhp very quickly and cheaply! Just don't forget to utilise the uno turbo hubs/brakes and suspension to keep it safe tho!

That is a good swap to do unoracer, but only if you start out with a non FIRE ohc Uno in the first place. Daviduno has a 1.1 FIRE, so the easiest swap is a 1242 Punto SPI engine. The 1242 will bolt straight onto the existing gearbox and the original mounts will mate perfectly with the Punto engine. The only thing needed to be done is to have a spacer made up for the exhaust manifold to downpipe to compensate for the taller Punto engine.

As far as I am aware, the original SPI system could be used on the bigger engine (not ideal), though the Punto SPI and ECU could be adapted I'm sure.

The 1498cc engine has a number of problems. First of all is finding one! I haven't seen a Strada on the road in years, and X1/9's aren't exactly in plentiful supply. Plus X1/9's want those engines as well.

Also, trying to find Uno turbo parts these days isn't that easy as most of the turbo boys are after them, they are getting rare and they aren't exactly cheap anymore...

Next problem for DavidUno is that his is a FIRE engined Uno, so he would need the engine mounts from a Uno turbo (or ohc non FIRE Uno), the entire exhaust system, the gearbox and possibly the wiring loom for the engine bay as some of the components for the 1498cc engine are in a different place. Even something simple like the thottle cable would have to be changed, and the front springs would also need changing to cope with the heavier engine weight.

If someone already had a 1.3/1.4 carb or SPI Uno, I would say go for it or even suggest the 1.6 Tipo engine (an update of the 1.5), which is also a bolt in swap. But for someone who already has a FIRE engined Uno I would suggest the bigger FIRE engines. They can also be adapted to run on carbs if necessary, using the same twin choke Weber as fitted to the X1/9!

Also bear in mind that a 1242cc Punto engine with appropriate mods (Tricker throttle body, 75 camshaft etc.) can push out over 90bhp, plus has the advantage of being lighter than 1.5/ 1.6 engine.

I originally wanted to do a 1.5/ 1.6 swap, but because of the ease of the Punto 1242cc swap (and the fact that it is a more modern engine) that would now be my choice. If I had the money I'd go for a 1242cc 16V, or if money were no object I'd fit the 1.4 Super FIRE 16v engine that's only just been released.

Either way, I think DavidUno would be best going for a bigger FIRE swap rather than 1.5/ 1.6 if he isn't that experienced in engine changes.

Have you any pictures of your Uno Unoracer, and any details on how it was built? You might tempt a few of us to go the 1.5/ 1.6 route afterall

i had a 45 s fire engine as my very very first car, i thought for a 999cc engine it went very well.
The best swap i think you can do is swap the whole lot for a turbo, you can pick up a nice clean uno turbo for 1000 quid, i'm sure a engine, gearbox, loom, ecu, radiator, etc etc will cost you far more than just buying a turbo ready to go.
I picked up mine on ebay fairly cheap and there are always mk1 turbos on there you just need the cash to grab on.
I know of a whole turbo complete but the shell is rotten out big time, how ever it will have every part you need to gain another 60 hp with out costing you the world.
My advice would be to turbo it..... Get them picks up
