Hi everyone,

I would like to find out IF it is possible to install a Coupe 20v Turbo motor into my mk2 Uno Turbo body.

If I would install the motor, would I need to change the gearbox or is the gearbox a straight fit? This is my main concern. If it is a straight fit, then my GB and linkages would be no problem,,, the engine mounting is not a problem for me. The coupe motor isn't such a big thing - in size wise - to fit into the the engine bay as I have seen 2L Mazda and Toyota TwinCam that is Turbo'd or Supercharged motors being installed into these bodies, from the outer look nothing has been changed but when you open the bonnet,,, that is a total different story.

Now!! I have my Uno Turbo for close to 14years and I wanted to go the different route of making it a half bread Uno Tubro with a Jap motor instaled,,, BUT I want to keep it FIAT. Fiat body and Fiat motor,,,

Please,,, any advice on the good and the bad and PLEASE,,, the how to and what to look for

are these 4 cylinder engines though? remember the coupe is a 20vT is a 5 cylinder and so it will be wider.

I know that the 20v is a 5cyl but yes the Toyota and Mazda is a 4cyl but quit big in comparison with the Uno Turbo motor

This is what I have

MK2 Uno TUrbo
- The head is a bit worked on - not by someone in Cape Town but by myself - 8Years ago
- Motor wise is Std - std pistons, valves, ect. -
- Std Injectors
- Std MerelliBox - Spark -
- Aftermarket Management - EFI Mr Turbo - replacement for the Airflow Meter -
- Turbo - T2.7 Garette boosting .9B -
- s.m.a.r.t Dumpvalve
- Inter Cooler - LandRover Deffender -

I raced the BMW M3 V8 Friday night and it was big sports,,, 1st,, 2nd and 3rd I was in front with about 2 car lengths,,, 4rth my clutch can't keep up - slipping -

hi...

i don´t think there is a problem fitting the 5cyl engien in to the uno..

your gearbox doesn`t fit the coupe engien..its really easy to build a new gear linkage to the coupe gearbox... its even more simpley if the gearbox has wire linkage

good luck!

anything can be done. personally putting an oversized engine in ur asking for trouble with handling issues. great in straight line though. a bottom less pit of money defo helps

its been done with a mk1 punto but the car handled terribly,had a terrible steering lock and was more an exercise to see if it could be done
the 16v is a more realistic goal

100% agree.

You can do anything, but the list of problems and alterations to the layout of so many different parts will just go on and on.

You would either need very, very deep pockets to pay for it to be done, or deep pockets, and a lot of time and energy, plus a very good understanding of mechanics.

16vt is pain to some extent, and perhaps alone more than you might expect, i dont know?

In my opinion, if you start to consider engine conversions, you should look at a different base, and after going to 'The Ring' this year it was brought home to me just how much bhp (in the real world) is far less important than brakes and handling.

Buy a grale'!!

I can get the gearbox and motor of the 20v for R12500 here in South Africa,,, I have only seen 4 of the Coupes here. To me it is no problem to fit it,,, the only problem is the parts,,, The Uno Turbo's parts are SO scares here or if you find the part, you must then be prepared to PAY for it. What we also do here is the Palio16v head conversion but are too many engineering things that needs to be done to make it fit on the UT block and that cost plenty of moohla R,,, The other thing I can do, is to get a 1500 x19 block and bore it to a 1600 and fit Opel TS pistons with a T3/T4 turbo with meth injection but that block also is scares,, so I thought that a Coupe motor will do some good trix especially with the ST Focus with their 5cyl motors that sound SOOOOO good

if you go for the large engine bear in mind the handling. it will over steer like a bitch, and probably pitch and roll all over the place. stopping the car will be a problem too. you should think about seem welding high stress areas too if you go ahead with the project.

I think you meant 'understeer'. Which is technically defined as when 'the slip angle of the front wheels exceeds the slip angle of the rear wheels'. In other words, there's lots of steering lock wound on but not much cornering taking place.

The more front-heavy, the more the tendency for the front to plow straight on rather than change direction.

Personally, I'd just buy a Coupe. Or, the Integrale that Tom suggested.

the weight difference in the engine + gearbox amounts to 52kg. that is a big difference but alot can be done to take weight off the front of the car in other places, the battery for example can be moved too the boot, fibre glass bonnets and wings and lighter wheels. just make sure that some of the weight taken off the front should be put to the back to improve weight balance. it would make a big difference to handeling. as uno turboe'd said you should think about seam welding, stronger arb's, strut brace etc.... a good set of coilovers woud go a long way aswell if setup correctly

52kg - is that all?
I had the impression the difference would be a lot more, so that's interesting to know. I mean, when a passenger gets in, that's an average of 70kg added... But as you say, it's about having the weight in the right place and suspension suitably uprated (I fully agree with your advice )

-Alex

well theres 5 or 6kg extra with the weight of alternator, starter, turbo etc... but thats still a very managable figure to work with.

Is there enough space under an uno bonnet? the 2.0 16v is huge as it is, especially in comparison to the 1.4. the 2.0 16v is virtually touching the bonnet in a tipo, and the 1.4 looks lost in the same enginebay (i'm comparing this in the tipo's i've owned) and the 5 cylinder 20v unit is even bigger, as far as i understand. if it fits though there's no real reason not to, but suspension, and brakes would need uprating too. i'd be suprised if the difference in weight is only 52kgs though?

typing error there lads dunno wat i was thinking. the extra 50 kgs is a lot of extra weight over the front wheels, not easily to lose. front engine front wheel drive cars are difficult to balance as theres little weight over the back axle. front engine rear wheel drive can be balanced lovely.

i was thinking the same thing, looking under the bonnet of my mates 20VT, theres barely room to swing an ant in there, and the bay is a lot bigger than an uno, maybe some jiggery pokery and shifting stuff round, but it's gonna be a right old ballache, and what with all the ancillaries, i cant see how the xs comes to only 50 odd kilos

thoes weight differences are 100% accurate they come from eper. as far as i know theres an old version on the web, its prob on here. 52kg isnt that much to move, the battery weighs about 10kg mabye a bit less, the original bonnet is 13kg, a good fibreglass replacement weighs about 5 or 6. mabye 2 kg could be saved on each wheel. thats an easy 20kg gone, could be a bit costly but it wouldnt be hard work. when we were building the punto abarth race cars we were able to strip 15/16kg (i think. ti was a long time age) just from cutting excess lenghts of bolts off, trimming excess rubber off. replacing most non structural bolts with lighter alliminium counterparts. hes gonna have to have the car or at least the engine bay stripped so the bolts might as well be replaced and theyre not that expensive, its an old car and chances are alot of them could be rusted beyond re-use anyway.

as i said before theres no reason it couldnt handle ok. every little helps
as for the engine itself fitting in the bay im not too sure.

there is a guy on turbo collectives thats running a 1.6 intergrale engine but next year he is going for the 20v coupe turbo engine so it can be done just takes time go on the forum and speck to the guy

integrales are all 2.0 8v or 16valve, are you sure someone on turbocollective is fitting a coupe engine, or is it wayne with the hf engines.
