Right, as i think my current EFi N/A cvh is on the brink of going ka-put - im after something to replace it with while i rebuild it.

I have in my possesion :

* A spare (prepped mint) 89 EFi CVH head.
* Head gasket kit for aformentioned head

My mate has (in his garage - doing nothing) :

* A good 1800 Zetec Bottom end.
* various escort zetec parts (water pumps, sumps, etc....)

...can you see where im going here folks...

Will it mate up ok and run ok as a 1800 N/A ZVH or is the compression ratio gonna be wrong for normally aspirated? And is the N/A EFi wiring/injection system going to power it ok?

Read various guides all over the net - the conversion seems easy enough - but they all seem to mention turbo's.

Would make for an easy swap if so. Could build the new engine out of the car, then drop the old cvh out, stick this one in, bolt all my standard manifolds to it, away she goes.

Anyone pops the bonnet - it looks like a 1600CVH...

Any info - much appreciated....

Right - i've been on the phone to another fellow 'ford-nut'. He's done a 1.8 ZVH on carbs, and reckons that so long as my head hasn't been skimmed much in the past, if i take 2mm off the head and bolt it all together, I can just bolt all the CVH EFi bits back on and it will run happily provided i fit a chip to the ECU and possibly an adjustable fuel pressure reg (or FSE boost valve thing)

Does this sound about right?

Can't be arsed to get it all done if its just going to self destruct on the first start...

Sounds good to me as I can get good used zetec bottom ends a lot easier than good cvh bottom ends if it does nail the pistons....

Any info much appreciated - as im raring to get de-greasing/cleaning/modifying etc....

1.9 xr2 on 40's

all zvh i have done are turbo but i would deffo build it up, just before teh skim put some bluetak on the pistons and see it 2mm is too much
easy


but, its considerably more worth while to get a mondei 2.0 fit the 1.8 (fiesta or escort) sump and pick up, and drop that in complete on 130 spec managment a free'd up manifold and and nice bit of air filtering, will make about 150 nags and be very nice, could bang on a low blow turbo kit and a frst managment and go a bit further if you wanted later on

Everywhere i read about ZVH it's all turbos turbos turbos....

I like the idea of opening the bonnet and seeing a 1.6 EFi CVH with nowt special....

And i like the availability of good 1.8 zetec bottom ends....

Again if i get bored - the 2.0L mondeo engine is another option.

Just need to make sure it'll work off the standard EFi management. Hoping it will so long as i get the compression right.....

(I'm liking the blu-tack method.... )

i have a zvh that i am rebuilding so i have everything just gaskets to get and shells etc ,but the headbolts are standard

Steve_RS

No, got nowhere with it. CVH still burbling away in the engine bay (and still being used daily) Driving it till it dies - might give me the kick up the arse to do something about it then.... lol

mobb-black

you could stick it on carbs?
