Using a CVH engine
Can I use a 1600inj CVH motor from an orion and what gearbox would I need? Also looking for some front wishbones to suit Sierra hubs if anyone is
selling
Cheers :

I believe 'conrodkid' tried to fit a FWD CVH engine but gave up trying to fit the ancillaries in the space available. I know it's possible to fit
RWD CVH's eg the 1.8 in some Sierras (and the advice is to fit a 1.6 head as the 1.8 is crap as standard)
Injection is the other bother - you'll need an injection fuel pump, tank with a return line, fuel reservoir under the bonnet plus all gubbins
associated with the control of it all. You'd be better off fitting a dizzy and carb off an XR2 and saving all the bother.
Gearboxes though... your in luck! The 'normal' mk2 escort box will fit onto the CVH!
I'm sure Conrod will add some comments about fitting the CVH!

I am also considering fitting a 1.6cvh. Looking at the basic westfield they use the 1.6cvh mated to a type 9 5 speed box. With the locost chasis
very similar to the westfield i can't see there being much of a problem. Check out www.sylva.co.uk they have some info on fitting a cvh to a
striker.

Thanks guys for your help. I might try the CVH without the injection as you suggest Chris. As the car is for fun use only I should be able to get away
with minimal ancilliaries eg v.small alternator etc
Thanks again

I heard that you can fit a small japanese one on the opposite side of the engine. Don't know if it's true.
Amazingly I have a 1800 cvh short motor, in need of a rering and reshell, it's for nowt if you want it

The sylva site provides most of the info you need however fitting a carb(s) to a transverse CVH injection engine is more difficult than it first
appears due to the cutouts in the head to clear the injectors. My advice if you intend to fit a carb use an 88 Orion head -- which full hemi and has
hard valve seats. -- the casting number for this head is 88SM6090 which is cast on the to of the head between the inlet manifold and rocker cover.
At the moment I am trying to sort a clutch that dosen't involve using a Sierra flywheel but uses a Hillman Avenger drive plate and a Sierra
1.3 4 speed cover (same as MK2 Escort and Avenger), with hydraulic release gear..
Of course you could just fit this head with distributer and carb on a Sierra 1.8 block

I have a set of engine mounts that I made up to fit a 1300CVH engine to my car, I managed to retain the alternator in the original position by using a
plate between the alternator bracket and block. I attached a box section to this and mounted on fiesta gearbox mounts, i also made a mount to use the
original front mount at the top of the block.This seemed a solid method of mounting the engine and only requires a 10mm hole in the chassis plate at
each side so easily changed later on.
I then was given a crossflow so engine and mounts are lying on my workshop floor looking for a new home.
U2U me if interested.
Paul.

Ressurecting old threads is fine as long as the content is contemporary, it usually is! A while ago, Nissan Micra rads were the only way to go, now it
is VW Polo's.
1.8 RWD CVH heads are not crap, but designed for the ultimate economy, you takes your choice.
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

And if you do, the compression ratio goes down to 7.5:1...
This is what I'm doing for a big block RS Turbo engine. Currently sitting in a shabby old Sierra

My maths made 8.2 to 1 starting with the 9.5:1 carb early Xr3 head but I was just gaesing at thre gaaskek thickness and deck heights.

CVH
Hi
Just to say the 1800 and 1600 CVH engines do not have the same inlet manifolds, the water ports are in two different places and are not
interchangable. I have a 1600 CVH manifold that does not fit the 1800. Not even sure if you get a 1800 one.

I got similar, but using a half decent composite gasket to deal with the turbo demands got me me 7.5 (the RST gasket is thicker than an XR3i one).
Seems to go OK, but scared of cranking up the bosyt

I've just seen in the haynes sierra manual a picture of a 1992 1.6cvh, never seen one in real life though.

I know, that's why it's in the bin, as it's also a CFI unit, not a plenum based job. I use the EFI 1600 with an adaptor plate for
the MFI head.
