I had a 188 punto sporting, I put a MS2 ECU and a turbo on it, made 160hp with original engine bottom end. It was the timing key that snapped on the crank, it still ran but was way down on compression. It just slipped a little bit.
I rebuilt that engine with a 1.4 bottom end and forged pistons, made 190hp. Then one of the conrods snapped and it set the car on fire, lol

That's a shame.
I've read an article while researching about FIRE engines modified to forced induction.
And stock are capable of 120ish BHP with low boost, they unfortunately have not combustion chamber designed to manage higher boost levels than 0.4 bar .
They knock if you don't work on compression ratios.
The 16V has a great potential for boost applications since you can even completely modify the valve timing by varying the overlaps and has s stronger engine block.

The main problem with the 8 valves is in the SPI system which makes cylinder 1 and 4 run lean, MPI surely better and ours have this system
I was searching at this for the 126p.

Anyways I've checked my car distribution and found it's way off sometimes it's spot on many other timing is way off .
So I think it's the crank pulley,It shouldn't be so difficult to remove it as it's bolted on with just an 8mm fastener .
I'm thinking to modify it to fit a steel key because I know it's a single cast aluminium piece

.....
Fire engine family is very easy and reliable engines its surroundings are little made with the feet

I fully agree, I believe they are assembled by robots in Poland?
I don't understand the last part of your sentence?

I did a turbo conversion on an 8v as well for someone, i used an extra injector controller with 4 MPI injectors in a modified inlet manifold to provide the fuel, and a decompression plate under the head gasket. It made around 120hp with 0.5bar boost IIRC, it was a long time ago now.
I thought they were MPI? The mk1 punto 60 and cinquecentos etc had SPI. Or maybe I'm remembering wrong.
I thought the timing key was cast iron as all part of the bottom pulley.

Great engines the FIRE engines. Fiat has always been good at little engines.

It's a way to say instead of working with hands they use their feets

MK1 Punto 179 ,uno ,panda 141, tipo, 600 , cinquecento had either SPI or carburettor .
MK2 Punto 188 had MPI.
Great engine

Modified a cheap Bosch angle grinder to make it run along a linear rail. Trimmed all the newly made glass lenses to size with a diamond disc. Lenses pretty much indistinguishable from the originals when in the housing. Will call that job done

Is your son's 500 twin or four cylinder?

1.2 four cylinder.

1.2 four cylinder.

My same engine, probably same code too
188A4000 ,it should have a variable timing camshafts,those things make the engine much less reliable,it should work by an actuator on the valves cover which operates a valve on the oil line to the camshaft.
This pressurise the cam pulley advancing the opening of the valves to increase high rpm performance (useless on a city car on the Panda 169 chassis) .
How I know it does that because it's what's happening on my car and in fact it's perfect from 4k to 6000 RPMs but mine is because of the broken timing pulley on the crankshaft.
Practically does what we do on two strokes when we lift the exhaust port ,it opens before, higher exhaust pressure and way less torque.
At least I believe it's so .
I'm now curious and I'm going to check.
But I'm sure it's not a variable lift system because we work on lots of those heads at work

My boys car is the single cam engine without variable valves. Nice and simple.

Single cam FIRE doesn't have variable timing. In fact neither does the 16v. Only the 1.8 HGT had a variator on one of the cams.

It does,newer versions have it

Likely different markets had different configurations?

Probably, fiat it's not new to that
Example are the Poland version of the 126 , which never had electronic injection here in Italy but they did in Poland
Or just the camshaft of the little 126A1000 was much more aggressive on the FSM made ones

 

[Hood]

Made most of the parts.

Stainless bolts.

the main slider parts.

One side has to be deeper at the clamping section than the other.

Fitted together.

Still have to bore/tap for the M5 dog point that will retain the bolts and also make the clamp plates, once that is done I will anodise everything.

Mostly, I made a large hole in my electricity consumption by TIG welding a strange and bobbly confection of peculiar shapes, reminiscent of pillow lava.
Setting together 1.5 mm thick aluminium sheet components.
That being said, it has turned out to be pretty strong, and has an amusingly rustic aspect about it, once it was suitably dressed back.
Worthy of a place in some art collection, I don't doubt....

Started my new lid for the little CNC Mill, swapping a bit of ply for some Ally chequer plate. Snag was I don't have a big enough piece but I had two bits and I have an AC TIG.
First thing to do, cut to size and fold a seam:



Then put them up and check the dimensions:



Yes, the bit will be big enough so I will tack it all up first then cut the profile out, if anything this will actually make it stronger than just a single piece. Just couldn't be without the Morgan folder, such a versatile tool.
