1.6 CVH??
Hi guys,
i've been restoring an old '84 mini clubman 1098 for a number of years and due to the lack of engine function have decided to go for an
engine upgrade. A friend of mine has a fully working 1.6cvh turbo engine, although the turbo and gearbox aren't on it, and he's offered to
give it to me seeing as he doesn't want it.
However, i want to do the appropriate research before taking on a new engine.
so my questions for you are:
1) is the 1.6cvh an engine with lots of problems? i've been reading a bit on the forum and a lot of people seem to be moving away from them!
2) the zetec is based on the cvh, so will the engine mounts be the same? i'm aware that there is a kit available for fitting a 1.6 zetec to mini
clubmans, and it would be nice if the mounts were the same.
3) should i go ahead with this transplant, what other gearboxes would be able to fit onto the 1.6cvh that would be easy to get hold of?
4) if i decide not to go with the turbo, what changes would i need to make? i know i'll need to block up the turbo oil feeds and also change to
carburettors (would that mean i wouldn't need an ecu??)
5) If i do go with turbo, will i be able to get hold of a turbo system easily? and what would be a good ecu to take on?
This is my first project car as well so i would like it to succeed!
any answers to any of these questions would be more than helpful!

ive knowledge of 1.6 cvh but none regarding fitting a CVH to a Mini, but have seen pictures of a zetec in a clubman
in responce to your questions:
1) is the 1.6cvh an engine with lots of problems?
i personally think the 1600 cvh enging is ok but limited in tuning potential etc and that is why most change it, also its not the lightest of engines
which may be an issue in a mini, just because engine is free doesnt it make it best idea especially considdering all the extra bite you need, a K
series may be better
2) the zetec is based on the cvh, so will the engine mounts be the same? i'm aware that there is a kit available for fitting a 1.6 zetec to mini
clubmans, and it would be nice if the mounts were the same.
think the zetec is a totally different engine the the CVH and dont think mounts will be same, if a kit is available for a 1600 zetec this may be a
better option over the CVH
3) should i go ahead with this transplant, what other gearboxes would be able to fit onto the 1.6cvh that would be easy to get hold of?
most early FWD fiesta/escort gearboxes think its the BC type will fit it depends on gear ratios you want and space as the 5 speed is longer than the 4
speed, all reasonable to get hold of
4) if i decide not to go with the turbo, what changes would i need to make? i know i'll need to block up the turbo oil feeds and also change to
carburettors (would that mean i wouldn't need an ecu??)
Running a turbo engine as N/A not really an option as it will be a low compression engine
5) If i do go with turbo, will i be able to get hold of a turbo system easily? and what would be a good ecu to take on?
If going with turbo the fitting with all orignal stuff like manifold, ecu etc would be best but if orignally fitted with ktronics injection system may
not be the simplest
Finally IMHO just because engine is free it may not be the best route and cost a lot more in long run, i would look at more proven conversions
personally

Zetec is bassed on the US spec 1.9. The cvh wasnt that bad in its day and the main problem was valve stem seals. The turbo was fine untill over
boosted with poor managment. Ecu prices for these are daft.
Better engine for the mini would be the MGR K series. You would buy a full car cheaper than a RSturbo ecu and loom.

And some cam and follower wear problems. Probably wouldn't be my list of engines to transplant, with or without a turbo as it's just too
old and there are many better choices. Also the MTX75 gearbox is pretty bulky and the IB5 is a bit on the weak side for a turbo install (only rated
to 110lbft).
The K series is obviously a popular choice, but if you head over to the 16V Mini forums you will see a
vast range of engines have been shoehorned into minis.

Not the best engine but cheap easy power. 200bhp easily achievable without opening the engine up or upgrading management (other than chip).

For the work involved in putting a different engine in a Mini I would want to fit something that suited it well, I've been there!
For the purposes of a trackday car which later became an Autograss racer I fitted a Montego Turbo into the front a of a Mini, too big & heavy (but
like your choice cheap & I was young & daft!). It was bloody fast in a straight line but lost much of the Mini's handling advantge due
to the weight. I later converted it to the 16v from a Rover 820, same bottom end, gearbox etc but more plentiful cheap engines & better suited to
grassing despite having less power than the 8v turbo.
The CVH will be a bit smaller than the old O series Montego engine but still much bigger than the A series! For physical size to CCs the VW 1.8
engines are fairly compact & the 20VT ones as powerful as you could want & Honda engines are very popular. As MikeRJ suggests the 16v Mini
forum will show you what folk have done before, when I built mine most folk had never heard of the internet including me by some margin!
I have seen a CVH turbo in a Mini, but in the back!
I'd thought the CVH & Zetec bottom ends were closely related, folk using the 2.0 Zetec block with as CVH head in race series where they were
restricted to 2 valves per cylinder & putting 2.0 Zetecs in mk2 Fiestas becuase the bolted right in & just needed plumbing electrics sorted?

I've seen that mini too. You are correct in that the zetec and CVH bottom ends are very closely related and hence the CVH head is easily fitted
to the zetec block to make a ZVH.

The easy choice would be a Metro Turbo engine ---

There was a Ford cross flow conversion at one time using a Mini gearbox . Peter Baldwin had a BDA engine in one of his race cars so it may be possible
to fit a Zetec to a Mini box but how long the box would last is anyone guess.
