Hi, im currently building a kit car with my dad which uses the ford DOHC engine. Its before the zetec came along, so im guessing its out of a sierra or granada?

Basically, what engine is it similar to? I wanted to know if it shares any similarities to a pinto apart from the 16v head.

Help, much appreciated

 

anyone?

 

is it a 8 valve you have or 16v mate ???

 

its 2 diffrent ones

you got the doch/zetec 16 valve found in escort/fiesta/mondeo/focus in a range of 1.6l-2.0l

and you got the doch 8 valve found in sierra and surly some other cars
in 1.8l to 2.0l dont know if they made a 1.6l though


edit:

yeah you said its a 16v.
doch/zetec did come in silver top and black top

silvertop it stands doch on the top
black top it says zetec

blacktop came in 95-96-97-98 dont remember atm :-P
before that the silvertop 90/91---->

well, similarities... would say the cvh engine there. some parts fits over with small adjustin/customisfldfbonodsfsidfing
gearboxes fits over

 

Hi thanks for replies, no its neither blacktop or silvertop. im very familiar with zetecs as im tuning a sivertop.
Its from a sierra and its got 200 stamped on the block. It seems its very similar to the I4 engine as it has chain driven cams.

Any ideas?

 

the scorpios had 2.0 16v dohcs. and the Galaxy also had a 2.3 16 dohc (150 BHP).

Not alot of effort went into tuning these as they were expensive and heavy to tune, So people stayed with the pinto.

You need a forklift truck to lift up the flywheel on these lol, they are foooooking huge.
The closest match for these engines is obviously the rs2000.
I never learnt the differences between them though i think it was higher comporession and slightly better flowed head. i went pinto in the end.

 

I know mate, we had it delivered on a crate and took 4 of us to move the engine to the engine lift!!

The thing i was getting to, is, we want to ditch the standard injection system, and run carbs, as we dont have much in the way of a loom. My main concern is finding a suitable manifold to run carbs

 

Sounds to me like you've got the 2ltr DOHC engine out of a sierra/early granada...

They are basically a pinto block with a twin cam head and if i remember correctly they're only 8 valve

Not a bad engine tho, torquey + reliable and i think they kick out around the 135bhp mark

 

You should of said that anyway, The problem is that they dont run a dizzy, its all controlled by the ecu. So you'd need a basic 2d ignition ecu,

As for the carbs i think that the rs2000 head is similar which means that possibley a throttle body manifold could be sourced. Once again though these engines had such a short life span and a lack of tuning potential, parts are hard to come by. I think you'd be best making up your own manifold for it.

Or just get a real zetec = black top.
And buy my mates black top manifold for dcoes.
Whats the engine going into?

 

Ok, thanks again for the reply, but you lost me when you said it doesnt have a dizzy, because it does. The distributor is on the left hand camshaft if looking at the engine. Im certain its from a sierra/granada tho. If it helps, it has chain driven cams.

I really am stumped by this one, im familiar with CVH, Zetec-E and Zetec SE engines. But this one really is different. On the cam cover its says 2.0 DOHC.
?????

oh and its going into a lotus 7 rep? similar to westfield etc etc

 

Whilst there is a dizzy on the end of the camshaft, the question is what would control the engine spark timing advance/retard without an ecu?

Yer you are right its from a granada, scorpio. Not a sierra though they only made dohcs in 8v format.

Hope you can find some more info out about the engine, I gave up and just chucked it out for a simple pinto. But One thing I do remember is that I ragged the crap out of the twin cam for 3 years and it never burn't oil, never let me down once. Toughest engine I ever had. And had real good low down torque.

 

Yeah, i have been told that actually its a proper solid engine, just wish there was more info on it! Im going to try and stick with it and see if I can find an inlet manifold i can adapt to take carbs. There are traces of the old loom left like sensors etc, but no sign of a coil or ecu. so carbs seem to be the best way forward.

Surprisingly, the engine is immaculate, no signs of wear on the bores or the cam lobes. So must be worth a go!

 

Yes mate this will be the old I4 DOHC 8-valver, it did actually come in a carb version as well so a bit of digging should be able to find you the correct Ford parts for the job.

 

hi this is true but the carb version used a different head

 

so different inlet pattern then? looks like ill have to get an aftermarket one

 

They are not a pinto block, they have a cam chain with a casting in the block for the cam chain.

they are related to the RS2000 I4 Unit, and the 2.3 scorpio or 16v scorpio unit, however as far as I am aware were never available in a 1.8 as ford had the CVH for this.

 

can't remember which is which but one uses round inlet holes the other square holes

 

The inlet holes on this are square, so are the exhaust.

Thanks for all your responses, its looking like its most similar to the I4 engine. Just want to get rid of the whole efi setup. Unless of course, i can get a standalone ecu to run it? Simple setup that doesnt require all the sensors? Just provides a spark.

 

Thats wrong

as is this:
Engine is designated the i4, and has NOTHING to do with the pinto, if you take the bottom end apart you will see a considerable difference. They are infact much stronger than the pinto, the block being comparable to a 205 lump in terms of strength and stiffness if not better.

8v is 125 brake as standard.

Tuning wise there is actually a fair bit you can do, however not a lot of 'off the shelves parts'.

You really want to start with a 2.3 16v from a scorpio, remove the balance shafts, fit rs2000 cam shafts and an aftermarket ecu, like this you can expect upwards of 170 brake and loads of usable torque,

As for carbs there was a guy from greece making twin webber manifolds on ebay....

If you are sticking with the 8v then i wouldn't bother messing around with the carb version, it used the wanky ford down draught carb and a slightly different head (no injector cut outs). I had one as my first car, if the second vacuum operated butterfly ever opened at all it was quite a good engine, but down on power compared with the efi.

if you need any info ie more than above give me a pm, i have owned more dohc sierras than i care to remember so can help you with most aspects.

I prefer these engines to zetecs because of their strength and massive torque spread, they also turbo very well, most people will not agree as they have ditched the engine due to lack of tuning parts, but with a bit of intelligence a lot can be done.

Rob,

 

also if you need any pictures i have quite a few, might help with wiring etc,

is this the engine?



found in these and granadas:



Rob

 

^^^ never seen it so clean lol ^^^

 

That is Exactly the engine in question. Cheers

 

Rob thats great mate, much appreciated help!

It seems ive landed quite a tidy engine then as there is such little wear on it at all.

 

No worries mate, i stripped an engine at 110k and it still had the original hone marks lol they are ridiculously reliable. weak point being the head gasket. However ford released a new metal layered head gasket for the 2.0 16v scorpio which will fit perfectly on the 8v, this is a common uprated replacement. So if your ever goes i suggest one of those.

Do a google for sierra fsoc, its the sierra owners club, i am a member and they are all very helpful, there are several sections devoted to twin cam engines and one specifically for kit cars using the dohc. Most of the people on there are very knowledgeable and help full so give it a go. Ashley also supply a 4branch manifold for your engine.

Rob,

 

Thats great, ill get the metal layer gasket for it whilst its out and i can get to everything easily. Ive got a 4 branch supplied for the kit, im not sure wether its any good but looks great. Im looking forward to just getting it running now.

Thanks again for your help
