Technical tipo to uno
the engine will fit no problem mate. straight swap as they use the 1.4 tipo engine in the 1.4 sx unos. also the 1.4 engine is basicly the turbo lump without the turbo!

it is a straight fit but the wiring isnt the same. ull need to swap over the engine wiring, prob drive shafts, gear box etc.
it really depends what engine your upgrading from.
the all of the smaller uno engines are completly different and will need mostof the drive components changed too.
the engine does fit though as the engine is used in the Uno 70. best thing to do is just go for the tipo 1.6 engine.. its the same as the 1.4 and fits too

thats basicly the older version of the 1.4... is it really worth it? you wont get that much more power
Indeed an awful lot of work, and if you put the 1.4 SPI you'll regret it - Gutless. The 1.4 carb was a nice engine though but I'd think any examples will be very tired by now. Tipo is a big car for a 1.4 to pull around for 10 years...
If you really want to boost the power then go ahead with it. If its a race car then transplanting a tipo 1.4 into it would be a nice project. Didn't realise it was for racing. Would still really reccomend the carb version.
People will practically pay you to take away their 1.4 Tipo so be fussy. You can afford to pick and choose your donor car. If possible have a drive in it. Engine should be really smooth and sound like an electric motor. Then you can start putting a bigger throttle body on it and exhaust, filter etc..

single point 1.4 tipo would wreck your race and your bank balance too! My parents 1.4 eat its throttle pot. Nearly 300 quid!
Do I take it you already have a tipo engine available or is that the uno engine you refer to?

You have me itching to start a track day car now.. I have too many projects already!

the 1300 engine can make an honest reliable 130 bhp with very good torque.not very cheap though.why not go uno turbo route.very tunable and reliable.
I would guess the catagory he is in would not allow turbos. upto 1400cc allowed so why not tune up a 1398 carb tipo engine?

about 140bhp should do it.Hellcat said:
if you can get 140bhp from a 1.4 tipo engine without killing yourself i'll clean your kitchen floor with my tongue!
Most points have already been covered regarding the engine swap, but I'll add a few more of my own.
1.4 Tipo engine should be a straight swap with the 1.3 Uno engine - I assume the mounts will all be the same. If you use the original 1.3 gearbox then you won't have to worry about driveshafts. However, I think (but am not sure) that mk2 1.4 Uno's used a Tipo based gearbox, and this MIGHT need different driveshafts. If the driveshafts are the same, then you can use the Tipo engine and gearbox complete, but bear in mind the clutch will probably have to be converted to hydraulic actuation. Otherwise stick to the 1.3 gearbox if that is working fine.
Everything should hook up as intended, the obvious exception will be the wiring to the distributor. The 1.3 had it mounted at the front of the engine, whereas the 1.4's had them mounted off the end of the camshaft.
If you want to tune for power, avoid the SPI system as it is rather restrictive and difficult to upgrade. There's nothing to stop you using the 1.3 carburetor and inlet manifold - it should in theory be a straight swap onto the 1.4 head.
As for tuning, anything that applied to the X1/9, 128, 127, Uno, Mirafiori & Lancia Delta 1.3 engines will work here. You can get the head ported and gas flowed, maybe fit bigger valves, balance the engine and do the usual tricks of 'blue printing'.
There used to be loads of performance parts available, and first thing to find would be a performance camshaft. Twin carburetors and manifolds can also be fitted if allowed in your racing series. Then it's down to a free flow exhaust and air filter, and a good session on a rolling road to rejet the carburetor and set up the ignition.
With a bit of work and choice components 80 - 90 bhp should easily be achievable. With a lot more money and time 140bhp is possible, though it will get expensive to get that kind of power.
One last thing, you could always get a 1.6 Tipo engine and have the capacity numbers ground off the block. No one would ever know
Good luck with the project!

I think that most 1372cc engines have a block-mounted distributor, FWIW.
The Tipo gearbox is the same as the Mk2 Uno 1372cc gearbox. That means different linkages to the 1301cc Mk1 Uno.
Incidentally there will be numerous little bits like the thermostat and the heater plumbing that are different between the Uno Mk1 and the Tipo.
The obvious answer here is to put in a Tipo 1580cc engine, using a Mk2 Uno for parts (gearbox, gearchange, driveshafts, cooling system, hydraulic clutch pedal box etc.) At least, that's how I see it.
Otherwise just raise the tune of the 1301cc engine - twin sidedrafts, hot cam etc. I'm not certain of the need for balancing and blueprinting the engine, unless you're aiming for peak power at 9000+ RPM. Chas - have you ever blown up a FIAT engine?
As far as power goes... I remember a FIAT 128 pictured in catalogues from the 70s that had Kugelfischer mechanical injection. Out of 1116cc, they got 165bhp. I think that proves that capacity is just the beginning...
So, not worth changing from 1301cc to 1372cc in my opinion.
Thanks,

Haynes Service and Repair Manual, Supplement: Revisions and information on later models: Chapter 13, section 7. Nice picture of a 1372cc i.e. engine with camshaft mounted distributor
To make it confusing, I think that some 1372cc engines had a block mounted distributor, and some had them camshaft mounted. Fiat obviously couldn't make up their minds!

I forgot about that
Yes, later Uno's had internal rod linkages, whereas all mk1's had external. Not sure if the two can work with either gearbox?alexGS said:Incidentally there will be numerous little bits like the thermostat and the heater plumbing that are different between the Uno Mk1 and the Tipo.

Yes, using mk2 Uno 1372cc parts it should be a straight swap into a mk1. Is there a lot of differences with the heater plumbing and thermostat between mk1 1.3 and mk2 1.4?
Bill/Uno can't go up to 1580cc as he's restricted to 1400cc in his racing class. But as mentioned, grind the engine capacity off the block and no-one will know

Nope, never blown one up yet
However, balancing/ blue-printing will make a more revvy and smoother engine, plus put less strain on the parts. If the engine is in bits, it's a worthwhile job to do. Might even get 1 or 2 bhp more due to less recirculating weight being moved around alexGS said:
A well built engine with the right parts can produce quite obscene amounts of power
But here's another suggestion to make a really strong engine. Why not find a 1301cc turbo engine with a blown head, then use the normally aspirated 1301cc head on it? The mk1 turbo apparently had a forged crankshaft and forged connecting rods so is immensley strong. The turbo 1372cc didn't have quite such exotic components so I've heard?
Also, the turbo came with an oil cooler as standard so this would be a help for racing.
Of course, non turbo 1301cc pistons will have to be used else the compression ratio will be too low. A bit or mixing and matching and a very strong and potent 1301cc engine could be built.

I agree, there appears to be no benefit at all in going from 1301cc to 1372cc. Going up to 1580cc IS worth it, as without any modifications you'll be getting around 80 - 85 bhp without any tuning work. A bit of tuning and 100bhp would be very easy to achieve, which is not bad at all when you think that a standard mk1 turbo is only 105bhp. Of course, a turbo can be hopped up to produce MUCH more power, but they aren't allowed in Bill's racing series.
I must get that sticker that says 'Fiats Are Faster Than You Think'
