As my engine and gearbox are out at the moment, I've been looking for any other jobs to do. I decided to buy a new clutch kit, but I was faced
with a choice of which engine type. Mine is N4A, as it's the 2.0 EFi, but the closest I was offered by the auto factor was N4B, which is the
lower powered one with a catalyst.
Now I'm unsure whether the clutch I already had was the correct one anyway! And which one to buy now. Looking at my pic of the original donor
clutch, which I binned, the central spring "fingers" are quite short, like the one here -

notice that one has 4 large springs in the friction disc. The pressure plate looks more like this "heavy duty" one -

Whereas my current clutch is more like this -

ohc-pinto-215mm-622017506.html - with longer "fingers" and 6 smaller springs in the friction disc.
I'm wondering, did I fit the wrong clutch?! 🤔 The non EFi engines only went up to 99hp, whereas my EFi has 114hp, so maybe it was
supposed to have a heavier duty version??

^^ I wouldn't worry unless your trying to make silly power from the engine
it'll probably make more difference if you pic a good brand of clutch - my engine builder recommend the bog std LUK one (the ones the burtons
sell) as thats what he used in his tuned competition pinto engines - he reckoned they were easily good enough for 180hp+ (and likely a lot more in a
lightweight car that will spin the wheels first anyway)
folk have use the same clutches on more powerful zetec's and duratec's too

I collected an LUK clutch kit today, for the injection engine. It has the short spring "fingers" like the original and the Burton heavy
duty one, so I'm very happy 😃😃
The original was Valeo and was probably fine! Only thing is I bought it 2nd hand from eBay years ago and I don't know the history (the release
bearing was new). The reason the engine and gearbox are out is due to a clunking noise when I raise the clutch to bite point after everything has
warmed up.. I've had the gearbox rebuilt, I'm changing the spigot bearing in the end of the crank, so I thought why not a brand new clutch
and release bearing to be definitely on the safe side!
On the catalyst Pinto, mcerd1 is correct - The UK EFi Pinto (my engine) doesn't have a catalyst, but there was definitely one in production, in
the United States, I believe.
