(T) fiat uno turbo ie 1988

Hello, i am new to the forum, and i'm a fiat owner since december last year. i've searched the forum a bit but could not find enough data for me to fully undestant the potential of this car. what i want to know is how to get more power from my car. how others did...

I have just rebuildt the engine as it was a wreck..334.000 km..you can imagine..i spent a lot of money on this..anyway..

i already have:
- boost controler
- blow off valve
- clean exhaust
- big intercooler (not fitted yet)
- plans for reducing weight

i read something about, an x1/9 1500 engine cam ...
and i also read something about water injection..but it is very dangerous if you do it wrong ..soo i am stil reading
please point me in the right way...


i attached some pictures of the rebuild procedure..

if you have a problem with my english ..is because i'm from Romania..

a couple of pictures with "the monster", interior, and engine..



come on people ..i need advice...I see at least 6 views on the thread..but no reply'.. come oooon..

Come onto Turbo collective for a bit more advice and infomation mate

67 views...1 reply...come on people..nobody knows nothing about tuning a uno turbo engine..come ooon...it;s my first FIAT...i know little about things...

As BIZ said, you'll get more response on TURBOCOLLECTIVE,

Dont think 'Louie' will agree with me at the moment!

charlie.

loving those recaros
nice to see other people putting them in unos

and yerr pop over to tc

141 hits(views) ..3 replys....i can not believe my eyes...come on people give me some ideas on how to increase the power of this engine..from what you heard from what you know, from what you tested...no matter..give me something...

Its not as easy as 1st precived mate

The engine responds well to a sensible turbo change (that depends on what turbos you can get hold of), when i mean sensible, i mean nothing bigger than a T25 or similer sized

Start small, dont jump to assumption that a race camshaft will give XX trq/hp because tuning an engine is like cooking, if you miss an ingredient then the meal isnt right

There is no set route for "Tuning" Uno Turbos, its a long one to figure that out!
The variety from one "tuned" one to another is vast so dont expect massive amounts of information on the subject

Start with basic things like increasing air and fuel to suite that air, intercooler and turbo along with BETTER engine managment, the BOSCH system is only good for standard so its not worth wasting your money making it work with more than standard

I know this because i went to Cape Town/Johannesburg over xmas, i met up with some of the Uno guys there, i drove one with 190KW (around 250-260 trq/hp)

Enough to get a Porsche 997 Carrera 4 out the way.....You dont need much in an Uno to make it quick trust me! lol

Super post there Biz I've met up with probably the same 'Uno Turbo guys' in Jo'burg One car had 'Yokohama' plastered all over it and another was dressed up in Speed'n'Sound livery. That was a few years ago now though!

Reality is that there's no easy answer, especially when you're starting with an engine that has 334,000km. Personally I'd get hold of another engine that's done fewer kilometres, and rebuild that with standard replacement parts where needed. I actually agree with the advice to try TurboCollective, even though I've hardly ever been there, I'm sure it's inspiring to read about big-budget modifications.

I guess I'm getting old, because I've decided to stick with the standard engine/standard turbo. It's rare to get something for nothing in this world, and a bigger turbo brings the problem of greater turbo lag. The standard turbo comes in with enough of a rush for me at 2000RPM, I don't think I'd like even more of a rush starting at 3000 or 4000RPM, it would reduce the driveability. Also, my particular Uno Turbo is amazingly economical (as much as 50mpg in open-road driving) and I don't want to endanger that.

However, like most owners, I fitted a bleed valve (boost controller), in line with the wastegate actuator. Even at the 7000RPM redline, the boost tends to go over 1 bar very easily and I have to adjust the valve carefully. I think the large exhaust (fitted by the previous owner) helps to liberate more boost from the standard turbo (but I could be wrong). After fitting a cone air filter (under the left headlight) I found that the boost needed reducing again. Therefore, these mods (big exhaust, cone filter) that normally produce little effect for non-turbocharged cars actually have quite an effect on the Uno Turbo. The best news is that when driven gently, economy isn't affected.

However, the big exhaust makes a tiresome droning sound on long trips, and the cone filter probably doesn't filter very well and would be a bad idea for a dusty environment. Always remember that FIAT weren't stupid - there is always a reason for the choice of standard equipment...

Water injection - keep searching. There was a South African page (the Abarth club?) that had great info on this. I'll try to find it for you.

EDIT: While I can't find the original page, I have found the same well-written text copied at http://www.tuning.bg/forum/viewtopic...65a697c0dc60e7 - I suggest you read it carefully

I think the best way to add performance is to reduce weight. Mine's down to 920kg measured on a weighbridge with me (73kg) and fuel (28kg) on board. Last time I measured it, it was 1000kg. According to the handbook, the standard weight is 895kg, so that's about 80kg saved by removing rear seats, soundproofing, stereo speakers, and unnecessary brackets. You could probably manage quite a bit more by fitting fibreglass panels (e.g. doors, bonnet) and plastic windows. As for the difference this makes - find yourself an 80kg passenger and go for a drive with, then without them.

Rather than creating more engine power, I feel that there's bigger gains to be had from improving the handling - lower the centre of gravity, fit stiffer suspension at the front, but do it all really carefully so you don't end up with a roller skate that snaps into oversteer at the slightest provocation. I think the back end needs to be softly-sprung so as not to overtake the front end... you want the back end along for the ride, but not locking up under braking or jumping sideways over bumps.

The best improvement is when you fit race tyres - "For competition use" - the ones with a treadwear rating of 50... Those alone improve the handling more than anything else...

If you want to build a 1600cc FIAT Tipo-style engine and turbocharge it, that can be done too (forged pistons, head gasket shim) but there will be many judgements to make on which parts to replace, head machining, checking the 1580cc block for warping, etc. You need someone to give you this advice in person - someone local to you who builds high-performance engines and knows FIAT engines well.

I think the forum is really valuable for advice, problem-solving, and ideas - but to manage a whole project, you'll need local help. However I look forward to be proven wrong when knowledgable Turbo-tuners read this thread. You have to be patient

i've got a turbo dynamics hybrid turbo on my mk1 and it spools up quicker than the standard turbo and can produce more boost,

Sounds good! Any other mods necessary or does it bolt straight on?

thanks for the info,
you have to know that the engine is 100% perfect, i have replaced ( or rebuildt) everything moving in it: reovalized pistons, rebuildt the engine block, the con rods were polished and broubght to the same weight. oil and water pump replaced unfortunately not FIAT parts (couldnt find them animore).....and the list continues ..but unfortunately i don't know the technical terms in english..the turbo was rebuilt too (standard one).
from my point of view it it as good as a brand new engine (at least it cost me like one ). it feels and runs like it should.
I will not exeed 0.9 bar of boost , will put a bigger FMIC, air filter (under the left head light..removing the pipe and filter box), removing everithing i do not need in order to drive the car, i found some kind of plastic for replacing the glass windows, talked to a friend for the fiber glass panels, bonnet and hatch.
i have now a hollow turbo-back larger exhaust
The car already benefits the advantages of lowering springs. the car has larger, wider better wheels(in the garage for the moment)

i hope i got said all...anyway i was hoping for a little more advice ..more like ..things you have done and know for sure that work..or something like that...general tuning ideas and advice are good ...but i am well over that stage..i think..

Where do you see the car?

Road or track?

I have another car for work and other things..the FIAT is just for weekend fun..it will be used mostly for drag racing but also for this type of event, i am in my fifth year of driving in this type of rally, a few link with my old car: the car is an 1976 Dacia 1300 L ...1300 cmc, 8v with 45 HP )
