1.1 Singlepoint to 1400cvh carb

Hey

Im new to this site,

Thought Id Let You know what I did,

I converted My ford fiesta Engine, From a 1.1 singlepoint, To a 1.4 cvh carb,

I had It straght piped, with a stainless steel universal back box, a Big Oval shaped bore, This type of conversion would have been more heared of 10 years ago, So To hear of it been done now would proubly surprise a few of You, lol

I just wanted a bigger engine for My fez, And I diddnt want to get involved with ecu wireing,

This conversion was not done By Me

I had It done by a local garage, who charged Me £250 labour, I supplied the engine, witch came with a twin choke webber (dont know if that is standard) The engine cost Me 1£20 inc vat, from 247 spares.

The noise the car makes from the back box is very very nice, But the speed is not too great,

Has Anyone else done a simular conversion, How Did They get on? Any tips would be great

Also, Would it be worth while converting the auto choke to a manual choke, As My chocke seems to be playing Up a little

Cheers Guys

Cheers Dave

Some Very useful info there mate,

What did You think of the 1.4,

What sort of carburetor did You have on it?

I see You have a 2ltr gti, I bet it shifts like the Wind.

I bet it brings back memmories for You to hear about My engine conversion,

My 1.1 singlepoint was burning oil badly, Was getting a cloud of smoke on start up,

Did You experiance any problems with Your choke?

Rob

32/28 twin choke carb (xr2 and 1.6 escorts) might fit, but you will have to find the right inlet manifold to match the two up.
I would go ahead and make it into a manual choke. I did when i put a 1.6 carb into my escort a few years ago. You have more control than the water controlled choke.
In what way is your choke playing up.
I also converted the car to a coil pack, as the original 1.6 engine i had was a dizzy and coil. the conversion for this is very easy as long as the block has the cut out for the CPS.

Post a picture of your engine and car!

Cheers Fellas,

Dave, Your Transformation Looks Tops Mate, It Truely Is a step By step guide,

My car was done a little diff

I kept My 1.1 gear box and fly wheel, And I kept my zorst as far as the 1.4 down pipe, So You could imagine the headake the garage man had, He had to cut out the cat, and do a few modifications.

The webber on mine is a twin choke, It Looks like the one in Your pics, But I thought it wasent the standard one for the 1.4?

sounds realy beefy though,

I havent got a k and n bolt on either, It sounds ok with out one, I just removed the nozzle off the standard dougnut filter housing, So i was left with just the rounded part, with a gap on the front, were the nozzle was conected,

If I was to buy a 1.6 head, on a re con, Will it come ported?

How mutch am i looking out for labour?

mg, Im gonna have some photos up of my engine 2morro,

cheers

rob

you need the old V5 i think to show where the engine came from to prove it was registered before 01/06/1992... I think

Cheers Lads

The cat was part of the singlepoint system, Pretty sure the 1990 cvh came with non cat

Im good friends with the mot tester, so I should be able to sort somthing out

here are some pics of My engine,

Can anyone tell by the pics what carb i have








You can see were I remover the Nozzle form the air housing




Thats the back box I have, with a back bumper



As Yo can see, Its Not in the best of condictions, Im thinking of it silver, from the strip down, and leaving the top half the way it is, What You Recon?

sorry for the bad photos, the camra was shite, also, dont pay any attention to the date in the photos, it was never set, These photos were taken 2day

it is a twin choke webber carb which is a good carb. You may have a metal tag on the carb that will tell you the butterfly size.. i.e 1.6 carb is 28/32

The carbs can suffer from carb freeze in cold weather, where the bottom of the carb freezes and it runs like a Constipated Turd. this is usally because there is no hot air feed comming from the exhaust manifold or the flap in the inlet pipe is stuck in the open postion for cold air.

looks similar to the 1.6 carb from the top.

So it Might be the 1.6 carb I have, Is it pos to run twin 40's on this head?

Im quite pleased with how she pulls, But it feels like im loosing a few seconds waiting for the second, bigger choke to kick in, I had 0 to 60 in close to 8 seconds

It does look simular to the carb in my car,

What came standard with the 1.4 (carb?)

not worth having twin 40's on. the engine doesn't rev well for it, and you probably won't see a major increase in power. The 1.4 doesn't really flow that well, and you will just end up with a large fuel bill.

You might be able to change the needle in the carb to allow more fuel in, but i haven't done this and can't comment.

there are a few different designs on the carbs, webbers different bolt patterns for the air filter, different inlet manifolds some with spaces some with out. There are a whole mix match for them.

pre 91 escorts and fiesta 1.4s

and you didn't have a 0-60 below 8 seonds... you may have had an indicated 60 in what you thought was 8 seconds

the carb doesn't kick in like a injection system it sucks.
The delay is the lack of fuel being sucked into the engine as you open full throttle, as a blast of air is sucked into the engine with a weak mixture. this only last for 1/2 sec ish.
this is the venturi effect and theres nothing that can be done.

Cheers Guys.

To be honest, When I first decided to go ahead with the engine change, I was doing it for better sound, We all know about the hcs, Micheal flatley type

Scorted, Im tellin You, Close to 8 secs, When i say close to 8 secs, I mean near to 9, But thats what I got, Dont forget, Im running My 1.1 gearbox on the 1.4, Pluss straght piped system,

As Tesco would say, Every little Helps, Im gonna try and film it,

Maybe whoever had the engine before me got stage 2 or stage 3 done at some point, I might even have daves old engine

MG, What type of filter is that on pic 2, It looks like a biscuit tin

Cheers Dave

Im starting to think that I should of got the 1.6 put in, But Because of My points on my lieance, I thought it might of been a little steep,

I suppose its a good car for sound, And Its in better condiction then My 1100 was.

On the advice ive been given, I have decided against trying to tune her up, Maybe Ill just do body work to it,

About 2 months ago, I bid for, and won an xr2i body kit on ebay, Witch never arrived, £110 I payed, All in, Delivery inc

The Geazer was givin me all this tommy tit about how its on its way, It will be there 2morro, This went on for over 6 weeks, So im in the middle ofn a claim through pay pal. gutted!

I was thinking of respraying it silver, from the strip down, And leaving the rest black, with silver xr2i body kit, I quite like the pepper pots aswell
Cheers
