1.1 Singlepoint to 1400cvh carb

Post by foreverford on Sun Feb 03, 2008 12:26 pm

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 120 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

I did this years ago in my mk3 fiesta.

Tho it was 1.0 carb to 1.4cvh carb'd

75bhp and thats if the engine is new, chances are with higher milage your looking 70hp.
Get a new camshaft and it will restore it to the full 75(ish) horse power
Or get a 1.6 head, get it skimmed to up the compression a tad... that should see a bit more power.
No point in head work on a 1.6 head as that can out flow what the 1.4 block could draw in.

The auto choke is controlled by the water temp.
The inlet manifold fills with water in water channels, it heats up with the water temp and when warm enough, the choke kicks off...

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?

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!

Mine was electronic ignition, with a coil pack and ingition module.

I use the 1.4 twin choke webber carb.
I kept the auto choke and it was alright.

The 1.4 i had was totally standard and had done 110k... so a worn cam and loud.
I made it louder with a k&n bolt on.
Compared to the 1.0 it was like a turbo... lol.
Heavier engine tho... have you upgraded the suspension and brakes?
The 1.0 had non vented disks, you need to have the vented as i found i over heated the solid/non vented disks.


Take a look at... http://www.davespages.co.uk/mycar.htm

My gti... they are a 1.8 with 113hp, 118lb.ft standard.
I went for a 2.0 and modded that, its RS2000 power now Smile

Welcome by the way.

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, Dont take the head swap lightly... tis a big task and judging by the fact you got a garrage to do your swap, then you'll be paying out loads again.

You might only gain a little bit of grunt from it, personally i would have fitted a 1.6 cvh... that would have got you up to 90hp.
1.6 cvh is very tunable, an XR2 carb and a piper or kent cam can get that over 100hp
One question thats been bugging me...

You have a carb, no cat on a car thats meant to have a cat... is your MOT now based on the age of the engine... I.E pre 1992?

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?

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.

Cheers Mg

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 Smile

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 Cool

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 Laughing

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 Laughing

Rob, the 1.4cvh fiesta has a 0-60 in 10.6 (when new) and thats probabbly the CFI version with no venturi lag.

RS2000's have a 0-60 of 8.2, a clear 1 second faster than the GTi (with a 1.8 )
So my 2.0 Gti is somewhere near to the low 8's but with all the ice in my boot... shave half a second or so off that!

That carb is the standard 1.4 carb as thats the same as mine was.
My 1.4cvh came out of a 1991 1.4 escort... HUGE failure on MOT so i was given the car, i had the engine and cashed in by weighing the escort in. The money i got for the escort in scrap covered the price of a new 1.4 exhaust for the fez, and appart from little bits like oil and cam belt... the conversion cost pennies as me and my brother did it.



Nobody will have ported the 1.4 head, its pointless... the 1.6 head flows VERY well, well above 110hp.
The hold back is the carb - hence 90hp on a 1.6. EFI 1.6 cvh's made 110hp and with a good exhaust and a piper/kent cam can get up to 125hp.

You will never get that sort of gain on the 1.4.

Hence why i eventually bought a bigger car with a 1.8, it trounced over the fiesta.

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

I'd personally tidy it up and keep it smart.
No massive mods... but a set of xr2i rims wouldn't go a miss Smile

If you love your mk3's then get a fez Si.
Thats a 1.6 zetec, only 90hp but when you get bored of that you can fit a mondeo 2.0 zetec in, you wont get bored in a hurry with that.

Or go newer, get a fez mk5... zetec S. 108hp but its the new ZETEC-S engine developed by yamaha... very revvy lil buggers.
The zetec S is insurance group 8.

If your mk3 fiesta is using the escorts insurance group for the 1.4, then its insurance group 5 (as mine went up to group 5)

How old are you Rob, as a 1.4 fez shouldnt cost loads to insure?

Im 23, But I also have 6 pts for IN10 (no insurance) Witch resulted in me having to re take the test and everything, I was with virgin money, and on a 1.1 fez, I was paying 1795.

When I got My engine changed, they said i have to be over 25 to be insured with this kind of swap,

So i switched to tesco, 6 pts, and engine change all in for 1369

I have not changed My log book yet, but will have to do it soon.

I was looking at a zetec s, but I drank my money down, And Had to settle for far less lol.

There was also a 1.6 si cfi for sale around My way. 450, But it had 100k plus on the clock, It kinda put me off,

Its a good job I dont know how many miles my 1.4 has done, What I dont know wont hurt Me Very Happy

The air box was a standard ford one like yours, but i cut away the sides and sprayed it blue. It still filtered the air, and was still tight around the filter. I had a spare air box, so i had a play.
The air box is restrictive, it only allows air to easily enter about 1/3 of the filter, so taking the sides off allowed air to be drawn in easier. but in cold weather it was rubbish.

Ah, well i'm 25.
2 years ago (in april) i wrote of my old escort and an 17k merc at the same time.
So insurance is always a pain.
I too have 3 points, tho i got them in 2002 and no longer have to declare them.

My GTi is group 13.

At the time of the accident i had 3 years no claims, i lost 2 due to claiming.
I currently have 2 years no claims and will have 3 in november.

I'm paying 530 fully comp.

Jaysus Dave, Thats a bit of bad luck mate,

I used to drive a 1.8 Diesel fiesta, I wraped that round a fence aswel, I loved that car, bought me over to Ireland, And done 1500 miles while I was there, plus bringin it back to London.

Your Insurance sounds cheap, Well, I suppose thats what You get with a good few driving years under Your belt.
