2.0l zetec and MT75
I'm currently gathering the parts needed to build a 2.0l blacktop mated to an MT75 squeezed into my mk1 escort and it will run on bike carbs.
I'm happy with getting the zetec to run and have a list of parts to buy. but have a few questions regarding the choice of gearbox. there is
loads of info regarding the type 9 but the MT75 is a little patchy
1) which starter?
2) which flywheel and clutch
3) other than mounts, will the standard transmission tunnel be big enough to house the MT75?
lastly, if anyone out there has carried out the same conversion, it would be great to have a chat
thanks folks

1) The one that was on the gear box when in the donor. Or the 1.8 cvh Sierra. There is more than one that will fit and some of the same part number
that won't. One model number is the Lucas Lrs707 from memory. If you do a search it's the same one used for T9 or mt75 when mated to a
zetec.
2) Againg multi options here. I used a lightened 2.0 mondeo zetec fly and clutch that is 240mm. You could use the 1.8 fly and clutch or you could use
the 1.8 fly and re drill it for a pinto clutch.
Important bit is the thrust bearing. As the dohc fly is huge and deep anything else won't fill the gap There is two ways to do this.
The Westfield way is to glue a 20mm spacer onto the thrust bearing.
The Gbs way is to pull out the pivot pin and fit a longer one.
Both do the same job but the second is cheaper by a long way. I used the Westfield bearing.
3) I see it's been done but I have know idea if it would go into a standard low spec tunel.

1- I have a wisp starter motor as it gear reduction high torque , think it's the chv one.
2- we used the standard 2.0 later flywheel and clutch that came with the crate engin but had the flywheel lightened by dunnell when Paul did the heard
work.
3- not had an escort so can't comment I'm afraid.

On 1, with the Type 9 you have to take some material off the sump to fit it to a Zetec. Not sure if this is the same with an MT75, but worth
checking.
On 2, if you want a light flywheel the 1.8 CVH fits and weights about 2-3kg less than a 1.8 Zetec. However it doesn't have the sensor pick ups
for the crank position sensor so a seperate trigger wheel is needed. I think there maybe 1.8 CVH EFI flywheels with CPS but they are very rare.
I have the normal 1.8 CVH flywheel and it makes the Zetec rev very freely. Your clutch options may be more limited though.

Yep its the same but if he is putting it in a an escort I doubt he will be using the bt sump but I could of course be wrong. ?

Thanks for all the replies and info. I have an 1800cvh sump on its way. I'm told that will fit with no mods.
Do you guys recommend the type 9 over the mt75?

I am not a fan of the cvh sump as the newest one is around 25 years old. Not exactly bolt on with a black top as the oil pump is a little different
but it can be made to fit with a hammer. make sure you get the spreader plates.
Mt75 is cheap if you can find one and you wont easily break it. First gear is crap.
T9 is a little smaller and simpler but not as strong with out spending cash.

the cvh sump i have coming is brand new, i'm ok with a little cutting and shutting. T9 boxes are becoming harder to find now and surely they
will need a rebuild

Slight deviation on original plan if anyone is reading this. A type 3 box has been suggested. What are people's thoughts on this?

A type 3 is an ancient box used in low power Cortinas and some Capri's. Think it made its way into some early Sierras as well but not sure.
Its 4 speed only.
It only has a limited power handling capacity.
There are no gear kits available for it.
Basically a waste of time.
