Valencia 1.3 OHV into a Fiesta Mk2

[Rui Meireles]

HI everyone,

After much head scratching I decided I will be rebuilding my Ghia to concours, *original* spec. It's a 1.1 liter though, and looses too much speed going uphill, which makes it unconfortable now that I'm used to much more powerful machinery. That is why I am considering the 1.3 OHV route. I don't want a race/sports car as I have something else for that, just enough pep to keep up with traffic. Good fuel economy would also mean I'd use it more instead of leaving it collecting dust in the garage. I guess ~75 bhp, good torque low down and good fuel economy would be my *dream*.

Please don't tell me "get a CVH or a Zetec" for 1) in my country it's ilegal to fit a bigger engine (with the OHV no one will notice) and I don't want my car impounded 2) it would ruin the car's originality meaning I wouldn't be able to get it recognized by the national historic car club in a few years time.

Some of my questions include:
1) Can the original 1.1 easily be bored/stroked to 1.3l or is it worth it to get the 1.3 (I have two 1.1 in the garage already, that's why I'm asking)?
2) If I do get the 1.3 OHV, which car would be the best donor? Mk IV Escorts as they are 69 bhp stock IIRC? Is it plug & play or is there something I need to watch out for?
3) Which carb would be best (in keeping with originality, stock air box, etc), the Weber 32 IBF?
4) Can the 1.3 be bored/stroked?
5) Is head work worth it on this engine?
6) Any other tips/recommendations?

Sorry for all the questions and thanks in advance for any help you can give me.

Hey guys, no one can help?

From what I saw in the Haynes manual:

1) The difference between the 1.1 and 1.3 in terms of capacity is in the stroke length.
2) 1.3l has 38 mm inlet valves, 1.1l 33 mm.
3) There are no oversize parts available from Ford to increase the capacity of the 1.3l.

I did this years ago with the 1.3ohv out a mk4 escort van into a mk2 fiesta.

Just put the whole lot in with manifolds and carb from the donor engine. If you don't have the inlet manifold I would expect the 1100 inlet to fit. If you don't have a carb/inlet I'd use the 950 carb as it's not a vv(which are generally crap) and possibly drill the main jet out a touch if you need to.

The dizzy shall just connect up as well.

Just try and get the engine from a mk4 escort and it'll all just go straight in.

Nice looking car you've got there!

If you an get one I'd say dropping in a 1.3 HCS from a MK4 Escort would be the best route. Very economical and reliable. Better then the earlier 1.3 OHV as it has a Weber twin choke carb and ditributorless ignition.
Only 60BHP, but still should be quite nippy in a Fiesta.

Mk1 XR2 1.6 OHV does look very like the original 1.1 as well though, and that's nearer 100BHP

Torque !

[Ade]

Nah. Pretty sure the 1.1 is in the 50's for BHP value.

Haynes lists the 1.1 as 37kW at 5000rpm. Whatever that might be in BHP value.

Thanks for the input guys. I have however decided to go for fully original concours spec. Two reasons:

1. It was never going to be fast.
2. New plug wires made me realize it was never that slow to begin with.

Very happy with my decision. Now on with the "collecting parts" stage.

or simply fitting a weber conversion to the 1100 made a whole world of different to mine, Better on fuel, Nippier and quieter/smoother!

weblefeck, was your Ford VV in good nick? What parts did you use?
I read about the Weber 32 IBF but Microcat only shows the 32 ICH as an option, not the IBF.

Our 1.1 has a Weber 32 IBF fitted.
Not a factory fit item.
It's an Escort replacement item.
Fits the Ford VV manifold, but idealy needs a spacer plate and a longer stud that you get with the upgrade kit.
But you 'can' do it without the spacer.

Very worthwhile upgrade in my opinion.

Just for info,

37kW = 50 bhp.

That explains it Jason, thanks. the 32 IBF is indeed listed in the Escort section inside Microcat.

When comparing a brand new Ford VV with a brand new Weber 32 IBF, what gains are to be expected from the latter? Smoother power delivery, fewer flat spots, stronger bottom end, stronger top end?

I can't equaly compare as the 32IBF I fitted was brand new, the VV was not.
