Hi everyone im new to the site ive owned half a dozen uno turbos in the past and every time i sell one and try something else i keep being drawn back to the one car that puts a smile on my face every time i drive it.

Only this time i want one a little different ive found a mint 1989 Fiat uno 45s only done 50k its the cleanest straightest uno ive seen in a long while, i was just simply going to buy a rotten UT and transfer everything over, but whilst on turbocollective i saw an uno with a delta hf turbo lump in looks like it should have been in there from factory!! Got me to thinking would a fiat coupe 16v turbo fit?? The 16v turbo coupes can be picked up for alot less then a grand now and surely would make a great donor for the uno??

Please any advice or opinions woul be greatly appreciated and has anyone else done this yet?? Im not scared of the hard work and enjoy a good project.

Any engine will fit if you have enough time, facilities and deep pockets. However, if you're expecting a simple swap then steer well away from a 2.0 16v turbo engine. Just about everything under the bonnet will need to be changed/ adapted/ modified/ custom built. I don't know for sure but I think the Delta HF 1600 engine might be based on the sohc family of engines that Fiat used from 1116cc to 1600cc. Therefore a Uno with a 1116cc/ 1301cc engine will physically take the bigger 1600 engine on the existing mounts and use the existing gearbox. A 2.0 16v Turbo engine is a totally different design and would not offer the same kind of ease of transplantation.

Also worth bearing in mind that the 1.3/ 1.4 turbos can easily hit 150bhp with relatively few mods and up to 200bhp is achievable with the right parts. Above that kind of bhp you will simply not be able to get the power down on the road effectively - the Uno will most likely wheelspin and torquesteer all over the place. If you're going to build it as a 1/4 mile drag strip monster then go ahead, but for road use I doubt if it would be worth it.

I reckon the 1.6 Delta HF turbo engine would be a good compromise, otherwise stick with the 1.3/ 1.4 turbo lumps. The problem is that these engines in good condition are thin on the ground these days.

Good luck

Thanks for the advice, u seem to have your head screwed on!!
If as you say the delta 1.6 8v turbo lump will go then will the dedra 2.0 8v turbo or the croma 2.0 8v turbo as i have seen hf owners dropping these straight in the deltas? They seem to hike up the torque figures and be more tunable???

Dont get me wrong i love uno turbos but this time just want to do something a little different and more challenging than a simple swap over!!

Just because the 1.6 Delta 8v will fit does not mean the 2.0 engines will too. I assumed that the 1.6 Delta HF engine is from the same family as the 1.1/ 1.3/ 1.4/ 1.5 series of ohc engines (as fitted to the Uno 1.1, 1.3 (+ turbo), 1.4 (+ turbo). That's why it will swap in place of the earlier non FIRE ohc Uno engines, and bolt up to the standard gearbox, if that is the case. However, I am NOT sure on the origins of 1.6 Delta engine but I am fairly certain it is NOT from the same family as the bigger twin cam 2.0 litre engines. Therefore you will not just be able to drop a 2.0 8v turbo engine in place of a 1.3/ 1.4 turbo.

Added to this is that you have a 45S Uno that uses the 999cc FIRE engine. The engine and running gear are totally different to those fitted to the turbo models, so you'd have to upgrade to UT running gear before you can even think of swapping in a bigger engine. There's no way a 999cc FIRE gearbox and driveshafts will cope with much more than 100bhp!

Also, the reason that the bigger 2.0 litre 8v lumps will swap into the Delta HF is because the Delta was designed to take bigger engines in the first place. The Delta is a bigger car with a larger engine bay and also has the availability of running gear designed to cope with both the power and torque of the bigger engines. The biggest engine fitted to the Uno is the 1.5 sohc lump - the larger twin cam Fiat/ Lancia engines were never fitted as standard.

This is what I mean about it being a lot of work. You'll be looking at fabricating engine/ gearbox mounts, custom made driveshafts, modified hubs, brakes, exhaust system, cooling system, wiring harness, ecu etc. etc.

You'll also need to look at how much extra the new engine and gearbox will weigh compared with a standard Uno drivetrain. If you're lucky and it's all alloy it might be a similiar weight and you won't upset the handling too much. If it all adds up (bigger gearbox, driveshaft, hubs etc.) you'll be adding extra weight to the front and mess up the handling in the process.

This sounds like it may be a major project rather than just "more challenging"! You're also not the first to ask about fitting a 2.0 litre turbo engine on this forum, but as yet no-one has actually built one after asking. That probably speaks volumes as to the complexity involved. The only 2.0 Uno I've seen was a south African monster that used a Japanese 2.0 litre turbo engine. It required MAJOR surgery and restructuring along with serious money spent on it.

I'd love you to prove me wrong and find an easy (ish) big engine swap into a Uno but as of now there isn't one widely known. If there was, then I can guarantee more of us would already be running bigger engines Perhaps your best bet is to ask on Turbocollective about it as they may have more information on such a conversion?

Sorry to be the bearer of bad news, but the 1581cc 1.6 Delta HF Turbo engine is a twin-cam, not the same as the 1580cc single-cam Tipo motor.

Otherwise I agree with what Chas (1986Uno45S) said. This question comes up VERY often and we seem to be having the same discussion every time. Neither Chas nor myself have actually DONE this. There are some people here that have - so please do an advanced search in this section and spend an hour or two reading threads E.g. do a search for 'croma' in this section. Also see the thread "Fiat Coupe engine, want to install into Uno Turbo".

There's a picture around of a Punto with a 5-cyl motor squeezed in (in the Punto forum, obviously). I recall there were discussions about the effect of the extra weight on the handling and the effect of the width on the turning circle (restricted steering lock).

Even when manufacturers with big-time development budgets squeeze in large engines (think of VW with the Golf VR6 and Alfa Romeo with the 147GTA that has a 3.2V6) the results are not wholly satisfactory (bags of understeer, torque steer, and unstable braking). I know that those are big V6s, not 2.0L fours, but remember that the Golf and 147 are a size-up from the Uno.

Personally if I were in your situation, I'd build a turbocharged 1580cc Tipo single-cam motor (that is, combine a Tipo motor with an Uno Turbo head/gearbox/mountings) which may throw up a few problems (I'm not sure that you can use the 80-mm bore head on the 86.4mm Tipo block, may need to use a Tipo head with a shim to reduce the compression) and you'll need custom engine management, but 1.6 turbos have certainly been done before and I think the result may be easier to certify than a 2.0L twin-cam installation - no special mountings or driveshafts required - and the weight would be kept down. I believe this last point is crucial to buildng a car that's not only fast but also nice to drive.

It would still be a good challenge to get a 1.6 Turbo running right - not melting itself - getting the size of the turbo matched to the engine's requirements to minimise lag and maximise the torque benefit of the longer-stroke 1.6 motor (compared to the 1.3, which can be a bit sluggish off-boost due to the low compression ratio and relatively short stroke).

the 1.6 twin cam 8v turbo engine goes in the same as the 2.0 8v twin cam, i've seen it done and been out in the blue mk1 in attached pictures was 220bhp at the wheels

waynegts is the person you need to speak to he has a 1.6 twin cam uno and and is about to swap the motor for a 2.0 twin cam,

see attached pictures of a 2.0 twin cam uno turbo and a 2.0 16v uno

avanti motorsport sell the required engine mounts and driveshafts which you need to convert, the wiring loom is quite simple you only need to connect 3 wires to get it working.

I stand corrected

In my defence it looks like Lancia fitted a variety of engines to the Delta throughout its life, including the 1500 sohc 8v unit as fitted to the X1/9, Strada, Regatta and a few other Fiat models. I assumed (wrongly) that the 1.6 HF turbo used the 1.6 version of the sohc engine as fitted to the Tipo and early Punto when in fact it was the twin cam 8v unit. This quote explains what was going on:

"Initial production vehicles were fitted wth either a 1300 (actually either 1299cc or 1301cc) engine with a four speed gearbox or a 1500 (1498cc) engine with a five speed gearbox .
In 1980 it was awarded 'Car of the Year' by the panel of international motoring journalists.
In 1982 the LX, a 'luxury' model, and a 3 speed automatic transmission were introduced and the 1300 engine received a minor power increase. More significantly, towards the end of that year the range was revised again. The 1300 gained the five speed gearbox, the 1500 became available only with the automatic gearbox and the 1600GT was introduced, using the 1585cc dohc engine from the Beta, tuned to give a little more power (105bhp) and fitted with disc brakes all round."

Assuming (I've got to stop doing this!) the 1.6 twin cam is the same family as the 2.0 litre then yes, you can drop a 2.0 twin cam 8v engine in. And assuming (yet again!) that the Integrale 8v and 16v engines are the same basic design then yes, you can fit the turbo 16v engine using the parts available from Avanti as Oldschoolmk1 suggest. But I don't know if the Coupe 16v turbo engine is the same as the Integrale or even the Croma (old shape) 2.0 turbo lumps. You'll need to investigate this.

However, I would also investigate the differences in weight between the UT engine and the 16v 2.0 depending on whether you want the car to be a daily driver that can be a giant killer in the twisties or a 1/4 mile monster. If the 2.0 engine is much heavier then the handling will go to pot. Also bhp at the wheels is one thing, actually getting usable power down on the road is something else entirely so I wouldn't build it solely with big bhp in mind. For a road car its far better to aim for a nice flat torque curve as there's no point in building a fire breather if all it does is wheel spin every time you touch the throttle

BTW, a Uno 70SX 1300 is quicker than a Lancia Delta 1500 :devil:

"The engine specifications, body aerodynamics and weight to power ratio produce a top speed of 161 km/h (100 mph) , acceleration from 0 to 60mph (~97kmh) 12.50s and from 0 to 100mph (~160kmh) -1.00s . Quarter of a mile was reached at 18.20s . "

http://www.scorpiocars.net/cars/car.php?ID=11572

The Uno meanwhile is fractionally slower on the 1/4 mile but quicker everywhere else:

"0-60 mph 11.30 s

Standing ¼mile 18.50 s

Top speed 167 km/h (104 mph)"

Now, imagine a 1.5 litre sohc engine in my Uno with 85bhp :chin:

the car with the 16v is my old setup

nowdays i have a 2,0 8v

looks like this






its actually pretty easy conversion.. i´v done worse :bang:

if you want any hints and tips..dont be affraid to ask.. but be prepered my english suchs!! :slayer:

Which gearbox is the easiest way to go on a 2l turbo conversion?

croma gearbox..

hello again everyone and thanks for all the comments, its nice to see so many different opinions! Ive now bought my uno and have started stripping it ill try and get some pics up after the weekend, ive also sourced a 1987 croma 2.0 8v turbo complete in running order done 81000 miles. £350 thanks to your advice, i hope to view it on tuesday next week and be bringing it back! Ive also e-mailed avanti about engine mounts etc needed for the conversion. Cant wait to get right into it will keep u all updated thanks gaz.

great choise...

i really dont like the 16v engien... i had it in my car for 2 months then i threw it out..

a good built twincam are capable of 6-700hp :slayer:

Are you sure? That's getting into Bugatti Veyron territory! Even with turbo and nitrous I think 6-700bhp is a bit extreme. If it could make that kind of power I doubt if the engine would last very long nor be very suitable for road use :-/

its no problem.. i can dyno my twincam any day of the week to 500hp with standard pistons..over that you need forged.. and i use stage 1 camshafts

700hp without nitros is possible..not for road use maby but for pure dragracing..

im pretty sure that the engien wont break.. use h-beam rods and good forged pistons,, good headwork and camshafts

the crankshaft is forged and it will defintly not break.. we cut a block in half and meassured it ..the cylinderwalls are 6mm thick and siames cast together... thats like strong like fu***ng Hulk

we have a guy in sweden who has over 900hp in his 16v, a really good 8v head is can flow for 650-700hp.. a friend of mine is building a 650hp 8v ..will post pictures of his machine on a later date.. its brutal

cerveza your nuts!! in a good way!!

Im hoping 250 - 300bhp in a car that should weigh less than 900kg, should be alot of fun and reliable! (ish) but as we all know upping the power becomes an addiction and 300bhp goals soon become 400bhp etc etc so ill just see how funds permit as the build goes on !!

Really cant wait to get into it, i own a bodyshop and have a good general mechanical knowledge so im hoping to make it a good all round car in the looks dept as well as tuning wise. Im toying with the idea of making the car look as original as possible (uno turbo looks) wise with all original decals etc no lairy bodykits! A wolf in sheeps clothing!!

mk1gaz,
are you the Gaz that sold me the lovely black f plate mk1 UT last year?, got to be you, skegness,bodyshop etc

regards Charlie.

yes it was me! Should have never got rid of that one there like gold dust now! how are you getting on with it, do you still have it??

Yes Gaz, still got the car, looking the dogs ******** at the moment [not finished but nearly there] .A before pic at the Scots border after i picked it up and as it is today

hi all
i am building a 1.6 hf uno and was wondering who are the best people for insurance quote's
