Ive got a mint 1800 130ps out of my old cab. Been told I cant keep twin coils with a ZVH conversion????? Any Ideas?? Cheers, Rich.

rsimark

i cant see any reason why not as you will be using yhe 16i flywheel although all of the holes on need slightly enlarging by 0.5 mm to fit the zetec crank, the 16i box is used also and fits directly to zetec block so it should work!!!!

Superb.... Will be giving that ago over the winter, Shes cammed and full st. Scorpion so a few more tweaks and should be fairly quick....... If ever back on the road!
Cheers, Rich.

I was originally going to do this to my RSi, but was told it wouldnt run on twin coils as the timing etc would be out in relation to the zetec although it could be rectified by installing a mappable Emerald ECU and having it mapped

Cheers.Sounds expensive that like!!
No one has answered my other question about the chassis numbers. Have you got any ideas wether ford can do them when new floor pan is fitted? No body seems to know and if im spending a fortune on the car I want it to be spot on...
Cheers, Rich

I honestly dont know mate, Ive seen a couple of mk3s where the floorpan's been replaced and there's either no number or the original numbers been welded back on as a plate Have you tried contacting a bodyshop/restorer to see what they suggest?

I'd try DVLA, think VOSA or plod has to re-stamp it once they've checked it all out

AD-RS1600i

If it worked I would of though the ignition wouldn't be correct or optimum.....Because the stroke on a CVH is different to a zvh and they have different requirements?

Would be a really really nice conversion if it worked

Compression ratio should be the same. 1900 Hurricane CVHs also ran very well in RSi's. I'd take some other kind of ignition, Zetec flywheel and OT-Sensor and the RS1600i twincoils

bigcorndog43

Cheers for that, Im thinking of building the engine then sending it somewhere, Any ideas who can do it I just wanna get the thing going!! But dont wanna get ripped off... Im moving to cleveland in the new year so somewhere near would be good.. Cheers

There is no reason at all why you cant run twin coils on a ZVH, the coils run off the fly wheel sensor which in turn is bolted to the gearbox.

You would have to use the CVH flywheel when doing a ZVH so run the RSi one as it has the pickup points for the sensor mounted on the gearbox for the twin coils and because you are running the CVH head then all the rest of the management would be fine as everything up top would be as original.

It really would not be a problem and would be the same as doing any other ZVH but you must run the RSi fly wheel and sensor (or something similar) for the coils to work.

It's Czech Mate

So would the non mappable ignition curve hard coded into the rs1600i ECU be exactly the same for the 1600 as a zvh?

It could run on twins coils but it'll need a mappable ECU to enable the ignition timing to work in relation with the 1.8 zetec bottom end

Like Kevs on the emerald Means junking all the K-Jetronic stuff tho too and adapting the existing, or making a new inlet manifold for suitable injectors.

Yep just like Kevs old RS (shouldve bought it when i had the chance ) its pretty expensive, but good it you want to have big power but keep the engine looking like the original RSi engine

Thats where everything comes to end! The management!

You can have every gizmo and gadget, but if they dont work 100% to your engine spec its pointless having it!

You could get a 16v working with twin coils and Mfi but whats the point?

Guess its just down to taste or orginality, to some people the 1.6i engine is a sacred thing which shouldnt be messed with, but if you can mod it and retain the twin coils it isnt so bad

XR2

At least a ZVH looks like the original 1.6 RSi heart. If the compression ratio is just the same like on the RSi it should work

Thats ok then..... as long as it looks ok in the engine bay...












Dont worry about if it works or not, just make sure it looks right
