I am in need of a DCOE inlet manifold for a 1800 CVH. Please PM me with price if you have one. Thanks.

I could be wrong, but don't think you can get one off the shelf.

could try burtons

www.burtonpower.co.uk

are the inlet the same as the 1.6 cvh ???

nope 1800 has the coolant come out of the head into the manifold. dont think there is one you can get mate

Bah, didn't know that thought they were the same.

Ok, assuming I can't get one off the shelf, what would the effect be if I made one up that blocked off the water channels or better yet could I put a 2mm plate between the block and a 1600 inlet manifold that blocked off the water channels?

I know someone who has fitted bike carbs on the CVH so something is out there.

The ports are the same just have to deal with the waterways, in the middle 2 and 3 ports on the 1.6 and at end of port 4 on the 1.8.

Let me search for a bit.

It was wrigglypig another Haynes builder, So as you posted above fit a plate between a 1.6 inlet manifold and the 1.8 Block

So you think it would work? In that case I am still looking for a CVH DCOE manifold if anyone has one.

the rwd and fwd heads are different but from what i can gather interchangeable so it may be worthwhile fitting a fwd head which puts coolant out on what would be the back of the head

Have a look at wrigglypig photo archive, bear in mind that several other things will have to change when doing the conversion from what I have been able to understand.

You will loose the main waterway that normally goes through the inlet manifold. Once this is blocked off you will have to remove one of the core plugs on the back of the engine and fabricate a water outlet to go to the radiator and house the thermostat.

I also think the DCOE carbs will foul the fuel pump, so this will have to be removed, the hole blocked off and use an electric pump instead. Plates are sold on ebay for about £3.50 for that.

Contact Mark I think is the best bet, in fact go for carbs as a cheaper option then the DCOE. If it makes a big difference on the 1.8 I am not sure, this is not a gas flow head. See pumaracing web site for general information.

Hope it all helps

Its really a cost cutting measure for me as I already have the carbs and the 1800cvh but dont want to put a hole in my bonnet so need to replace the pierburg with something else. I suppose I could sell the twin 40's and buy some bike carbs then copy what wrigglypig has done. Having looked at his build diary I didn't notice how he has dealt with the water outlet. I will have to have a closer look.

If you look in his archive

DSCF0712.JPG shows how the plate blocks off the water way.

DSCF0716.JPG shows the back on the engine and the right hand core plug is where you take the water from. It has two tapped holes to mount some form of thermostat housing.
