Technical Fitting 1242 16v to MK1 Uno!

[happypaul]

Good afternoon!

Well the time has come for my mother to finally give up the MK1 Uno 45s, and I shall be getting be getting it back shortly.

2 years of her driving has lead to a few tiny dents but other than that, its rott free, so I shall be giving it a going over and a repaint when I can be bothered!

Anyways,

I want to remove the 999cc FIRE engine... and fit something with a little more power, to give it some balls and to update it!

So, after reading through the "How to fit a 16v Fire engine in a Panda" is has given me some good tips..

So, the plan:

1242 16v FIRE engine from a Punto 85 / Sporting MK1 (in a 700kg car, will be nice!)
Engine loom, ECU, chipkey, and other gubbins for that
Manifold / Downpipe
External fuel pump, uprate the fuel line to the bay

I take it I can use the same gearbox that already in the uno.

My other issues are the wiring, is the engine bay ecu loom separate from the car loom?
I was thinking, use the existing wiring for the temp gauge
Using the existing wiring for the starter motor / alternator wiring
Wire in the code box, and tape the key to the box so it activates the immobilsor.

Would anything need to be linked from the punto engine bay wiring loom into the uno car loom???

Regards, Paul

Yes. All FIRE gearboxes will fit to any FIRE engine, of which the 1242 16v is from the same family of engines.

My other issues are the wiring, is the engine bay ecu loom separate from the car loom?

Pretty much, though there are some wires from a few parts that go from the engine bay to the instrument pod/ ignition switch/ switch pods. Otherwises the engine wiring loom is fairly self contained. However, you will need to remove most of the Uno wiring engine bay loom and replace it with the Punto loom. You should also be able to incorporate some of the original Uno wiring in with the Punto engine bay loom to make it all work. The classic Panda and Uno are similar, so use Panda Sport's 16v into Panda guide to get an idea of what you need to do.

Again, check Panda Sport's guide. He does cover what wires from the Punto loom need to be connected to the recipient car's loom. I think there's only about 5 wires that need to be connected. Also, if you haven't already then get hold of a Punto Haynes manual and reference the wiring schematics to see what wires go where. That will be a big help and will give you a visual guide too.

I am hopefully going to carry out a similar conversion on my 1986 Uno 45S and have been meaning to do so for the past three years. I kept getting side tracked by things like my University degree and other projects but hopefully I'll get round to it one day!

Good luck and let the forum know how you get on.

I've been looking forward to doing this conversion too, i can't wait only thing holding me up is finding a god damn punto sporting or a sx85 without engine damage.
hopefully be some advantage of having a injection uno to swap into.

More Brava or bravo 80 SX's around with the 1242 16V than Punto sportings No? much cheaper too at my local

Would the 1.9 JTD not be a more chalanging swap :tempt:

Wow, some good prices there - 250 GBP for a complete Bravo with 1242 16v! Only thing to beware of is that I think the Bravos, definitely the later models, used the fly by wire throttle as per mk2 Puntos? This makes it a lot harder to do the transplant unfortunately, though you could always find a Punto 85/ Sporting intake and throttle body to stick with a cable operated throttle.

Would the 1.9 JTD not be a more chalanging swap :tempt:

Much more challenging Louie! It's a much larger engine for a start, plus I think it's likely to be a lot heavier also. It will have bags of torque but the front heavy handling might send you into the nearest ditch...

 

[tattyoldvan]

i'm guessing the 1.9jtd is very similar to the old uno 1.7 na, however that in itself is a very heavy engine leading to slightly strange hanling if you go into corner bit fast. the saving grace is the 1.7 is so athsmatic you have to be on a mission to get yourself into trouble. however i can imagine the 1.9jtd would get you to that trouble area far easier.

Both brava and stilos are the more comon option but yes fly by wire seems to be the issue. but then i suppose i could pick up one of the plentyful sportings with blown engine. the mk2 punto is very comon is the £250 price range as the seem to have more of affinity to rust than a x19 or a strada.8-10 year old cars needing complete sills and floors is a bit concerning hope the panda and 500 are built better. anyone know why they rust more than the mk1s??

 

[Louie Bee]

Good point about the weight and resulting lack of handeling suffered from the JTD

Our 1999 Brava 80SX don't have a fly by as far as I'a aware.

Same reason why the Alfa 156 rusts out in the floor and the older 164 doesn't... general corner-cutting by FIAT, not using galvanised steel in important places

FIAT/Alfa hit a high point for corrosion-resistance in the early 90s. Cars like the Tipo, the Alfa 164, the Mk1 Punto, and possibly the Brava are very rust-proof, more than cars from other manufacturers. Later models are less so. No way to tell yet how the Panda and 500 will be...

My brava seems to be doing well and rust don't seem to be a problem on them and the bravos of the same era.. again who knows about the new bravo

I'd like to see this as it would be a nice compromise between a 45 and a turbo and something alternative!

i do think you should go for the 1.4 16v and not the 1.2,

 

[lewey]

i do think you should go for the 1.4 16v and not the 1.2,

Agree 100%. If your going to the trouble of having a modified car, you may as well have the extra performance of the 1.4 16v engine. You can get low mileage examples for £300. The 16v FIRE engines are hard to tune cheaply, so you may as well take the capacity advantage with no weight penalty. These engines are also more developed than the older 1.2 16v engines you have been considering and should be more reliable and use no more fuel in normal use.

Perhaps the only sound argument against is if you want to drop in an old 1.2 16v with its simple electronics and have no desire to tune it at all. As soon as you want to tune it, you are wasting money. Unless you have never driven more than a 1 litre car, I think a 1.2 16v may disappoint in an Uno.

I have a 1242 8v MPI (not the old 75BHP one though) in a Classic Panda. Similar power-to-weight as you proposed project. I'll be bringing it to the MITCAR show. Perhaps you might want to grab a lift in it to get a taster of what you can expect?

I got another Uno 60S this morning, I`m thinking about bunging a Punto 75 lump into it...

 

[Unclechuchu]

The engine fits straight to the gearbox, the starter doesn't. I was told that some 999 starters fit, but mine doesn't. The starter it self is too big, resulting in the body of the starter crashing in the block. I have a starter from a Punto 55, on which I only use 2 of the mounts. The project is paused and I haven't put electricity to the starter to see if it matches, but it feels/looks right. Any way, there is a solution to the starter problem, you just have to do some searching and trying.

I don't have a clear picture of how the intake manifold looks on the mk1 Sporting, but on the mk2 80 the intake manifold is too big to fit. I cut out the box to the fan/heater so it fits nice, but if you're gonna drive your car on the streets I assume you won't do that.

You should also notice that the exhaust most likely doesn't fit. I have a ss exhaust manifold and it collides with the gear linkage. I assume the original exhaust also does this. So you should either modify your gearbox to wire change, or just modify the exhaust.

Found one picture of the engine in the car:

 

[lewey]

You can grind a small amount of material from the block to allow the normal starter to fit. I have done this to the same engine block/gearbox combo recently.

I should really look at this forum more lol

Anyways thanks for the replies peeps.

Also, with regards to a 1242 16v conversion, I am unsure if it would go ahead, engine seem to be pretty hard to find compared to other engines, the mk2 punto ones are available more readily and they are easily used also i think.

Using a 1.4 fire engine would be interesting but the wiring part of things is going to be hellish complicated to even think about it !!

Might just leave it as 1ltr fire and deck it instead lol
