Technical engine change

[jason45]

hi guys was thinking at putting a 1.4 ie tipo engine in my uno 999 ie start 1994 will it fit right in or will i need the tipo engine mounts, will the gear box from the tipo fit in or would the uno gear box run it ok and what else would i need to change? all help would be greatfull please

OK you have lots of things to think about:

1. the 1600 tipo engine would be better
2. you will need an uno 1300 gearbox and all the engine mounts
3. you will need lots of of other bits from the 1300 uno (like flywheel, distributor...)

Its a lot of work (if you can get hold of a dead 1300 uno (or 1400ie) then you have the bits you need.

Something I just thought of, why not just get an Uno 1400 and use that engine? Straight swap.

I have the Tipo 1600 engine in my Uno and it goes well.

would the engine mounts off the tipo fit my uno or would it have to be the uno mounts?

I have thought of doing this but i've no seen any 1300 or 1400 uno's close to where i live in FIFE that is, at the end of the day i don't have the money for getting a car transported up from england. main resin i'm asking about the 1400 tipo is becuase there is one in the scrap yard near by and it hasn't been touched yet at the end of the day i don't have the money for getting a car transported up from england

As JJHepburn says, there's a lot more to the swap than just the engines. Your FIRE gearbox will not mate up as the bellhousings are different. The exhaust is also totally different, and a lot of the engine bay wiring is different as well. It's not a straight forward swap.

If you really want to do it then you're better off finding a 1.4 Uno and swapping all the parts over from that. And again as JJ says, you might as well go for the bigger 1.6 Tipo engine for the extra power and torque.

Or why not make things a lot easier for yourself. Swap in a 1242 Punto engine! It's a straight swap with all that's needed is a spacer for the exhaust manifold. Very little work needed and you'll get a healthy boost in power and torque.

If you want to be more adventurous swap in a Punto 75 mpi engine (not as difficult as it sounds) or even the 1242 16v Sporting engine. If money is no object then there's always the 1.4 16v FIRE if you can find/ afford one. These would probably be about the same amount of work as the 1.4/ 1.6 conversion (only because of the wiring/ injection system), but despite their lower capacities the power to weight ratio of the 1.2 mpi/ 16v would be about the same as the FIRE engines weigh quite a bit less than the ohc 1.4/ 1.6 engine. The 1.4 16v will trounce the older ohc Tipo 1.6! The bonus of using the FIRE's also being improved handling thanks to their lighter weight.

See PandaSport's classic Panda 16v (in the Panda section) to see how it can be done.

Yeah that sounds a lot easier witch punto would the 1242 engine come out of cause there is quite a lot of punto's the scrapys about here but punto's never have there cc writing on them so would it be like the 55 or 65 punto or is it the newer punto's?
sorry for being a pain just want to get every thing right before i got through with it.
one last thing would my uno gear box be ok with the punto engine or would it be better getting the punto gear box aswell?

Punto 60 = 1242cc and 60bhp
Punto 75 = 1242cc and 75bhp
Punto 85/ Sporting = 1242cc (16 valve) and 85 bhp

Best stick to mk1 Puntos as they use more conventional setups in the injection/ throttle body departments.

Easiest swap is the Punto 60. Swap it for the 999cc FIRE, fit a spacer in the exhaust and that's probably all you'll need to do. Ideally it would benefit from the ECU being re-mapped but it will run quite happily on the 999 ECU and 1242 throttle body.

Punto 75/ 85/ Sporting. You'll need to upgrade the fuel pump and fuel lines, the ECU, the code box for the key + a coded key (if it uses one) plus you'll need the engine bay wiring for the extra sensors and stuff. Check out the thread in the Panda section where PandaSport gives details of how to do the 16v conversion to a classic Panda. The same basic principles apply to the Uno as well.

The Uno gearbox should be fine as long as it's in good condition and you don't drop the clutch at 4000rpm all the time! The Punto box won't be a direct swap into the Uno as it's a totally different design. It can be made to fit but you'll be looking at extra work with regards to mountings, linkages and probably driveshafts. Your Uno 'box will bolt up to any of the bigger FIRE engines so stick with that

Here's Damon's guide for the 16v FIRE into classic Panda to give you an idea as to what's involved:

Right thanks for all ur help everyone who has replyed much helpfull, Think i'll go with droping the punto engine in for the now anyway will have to shop around for a decent punto engine and of course at a decent price thanks again

For what its worth I am about to have a "new" race prepared 1580cc engine from a Tipo built up and fitted to my race Uno to replace the 1372 unit that I destroyed earlier this year. The new engine should mate to an Uno Turbo gear box (Top Change Tipo type) and driveshafts.

The race engine prep won't be complete until Feb and then theres the installation to do so we might discover problems then, but it seems OK 'in theory!

 

[jjhepburn]

Your engine setup sounds kinda like mine:

1580cc engine
big valve cylinder head
reprofiled cam shaft
twin Delorto 36DRLAs
late Mk1 turbo gearbox (tipo type)

The gearbox is definatetly a good move, I just bought it so havnt tested it yet (still sitting on my garage floor) it is a much stronger gearbox so shifting in anger isnt a problem (nothing more annoying than not being able to down shift as you approach a corner).

I have found that good compression is essential with the 1580cc engine so make sure you have small combustion chambers in your cylinder head.

Our car club has its next track meeting on the 28th of Jan, 1 week after the A1GP cars will be on the same track, so I'll be able to see how quickly they could lap me . So I'll be able to let you know how it goes.

Enjoy Taupo - one on fmy favourite places in the world - fanatastic scenery and the opportunity to go to a race track, play golf, go sailing and go skiing all in the same weekend. I am sure that Taupo is Heaven in disguise!

Anyway, you can read more about my race car here:

Hope that no one minds the link.

Thanks

The race track is also ideally suited to our little cars (lots of corners and short straights). Although next time we are there we have the 800m main straight to deal with... (its a mixed blessing, its fun to get the car upto top speed, its scary trying to judge the braking point, and the fast cars pass you as you struggle along)

I'll have to wait until my registration is cleared on the forum before I can have a look at your car project.

I know for a fact that Unos with the 1.6ltr motor in them go very quickly. With a bit of tuning you can get as much power out of them as an Uno Turbo, but the power is constant and the torque is better at the low end. I am looking forward to seeing how my Uno goes against the UTs that turn up at Taupo (I am expecting at least 3 in various stages of tuning).

get a big V8 under the bonnet.

thats me done it now i got the 1242 punto engine and i fitted it in my uno yesterday toke me and my dad the best part of the day to drop it in but all is fine and she runs perfect lot better power now witch you's did say so thanks again everyone for all your help

Nice one! I assume that you're running the Punto 60 1242 so though there's not a huge increase in power the torque will be increased markedly :slayer:

Are you running injection or carburetor?

Yeah it's the punto 60 engine it's still running on the uno's spi carburetor the now had trouble with the punto carb so i'll have to got another one witch will probably be the spi one cause will the mpi not be a bit of a big job cause would i not have to get the ecu and it's wiring from the punto (in short is it easy to convert from spi to mpi? ) plus i've token the distributor off the uno engine and put it on the punto engine

It should run fine with the Uno SPi, though do a plug check to make sure it isn't running weak. Don't forget that the Punto ECU map is probably different to the Uno's, plus the Punto will be running twin coils with no distributor so it isn't compatible with the Uno's wiring. The MPi throttle body is no good because it doesn't have an injector! The MPi has four injectors mounted to the inlet manifold so the throttle body is really just an air meter.

It's not easy to convert from SPi to MPi. The MPi uses a totally different inlet manifold (with the four injectors mounted on it) to that of the SPi, plus the stud spacing on the MPi head is different to that of the SPi. You'd need the MPi head if you wanted to attempt to go MPi, plus a load of other parts as it is quite different to the SPi system in some respects.

Try another Punto SPi throttle body, and if that fails then you'll have to stick with the one from the Uno. By the way, how much of a performance increase have you noticed so far?

Thanks for that 1986Uno45s i think by the sounds of it all i will stick with the spi easier going i think, yeah i've noticed a massive increase in performance as the wording goes (like s**t off a shovel) thanks for asking.

 

[jjhepburn]

Yes, and torque is what you really want as well. Someone said to me recently; "Horse power sells engines, torque wins races".

From what I know Horse power is only useful when you are trying to get speeding tickets. Torque is useful when trying to pull away from intersections or power around corners. So you want high compression and good fuel.

 

[Bushboy]

Chas, you seem to have looked into this more than me.

Am I right in saying that doing the 1242 in an uno (from 999cc) is pretty much as straight forward as doing it in a cinq sporting?

Use everything the same except for the actual block itself (so use the 999cc flywheel and crank?)

Its still something I would love to have a play with. Would really love to do a 16v conversion but its still something ide feel uncomfortable trying even in a cinq/sei! Its just not documented as well as the likes of the 1242 8v conversion.
