Right, MTX have been brought up more than enough times now! But i couldn't find the answer to the questions i've got.

My cars been tucked up in the garage and im collecting parts for the next round of taking it to pieces.

Is there any way to fit an MTX without having to batter the inner wing? I remember seeing a white s2 at the pod last year with a 1600i (or s1 rst) ARB and the front gearbox mount was hung off this... IIRC it didn't look too pretty but it seemed to more than do the job!

Does any one have any pics? or the front and rear mount, im keen to to hack my inner wing about, at least not too much (i don't like the look of cutting the box section).

Second question.

Is there any way of keeping the equal length shafts with a cvh? If im getting shafts done then i may as well try and sort the equal length jobbies out, the centre bearing is it hung off the block or do people use a puma one on the chassis leg?

Third question (slightly unrealated)

I remember reading about a member using a zetec sump on their cvh... is this remotely doable? Predictable i have another sump leak and if i can use a sump with the shaft mount on then it would be a winner.

Rob,

 

sorry if i'm a little wrong here, but i've fitted an mtx75 on my xr2 and i only had to take 10mm out of the inner wing, if the escort on the bc box has more than 20mm clearance from box to inner wing, then shouldn't need any work, may just need to mill out the locating holes on the engine mount (drivers side) to move it closer to drivers side a touch.
no idea on equal length shafts sadly as i'm on a zetec, but it bolts to the block not sump, but a bracket to mount it could be made up.

 

focus shafts bolt the sump mondeo shafts bolt to the block.
you defo need to trim the inner wing on a s2 to fit a mtx box

 

/\ didn't know that, got shafts off a focus for mine. just had a look and they do bolt to the sump pan, never thought about them since fitting a few months back.

 

Thanks for the reply guys, shame i have to touch my wing but needs must i guess.

What do you think about mounting it on the rs1600i front gearbox mount? (the mtx that is)

Rob,

 

Shite if i'm honest. Use the same mount as mine off Gary. Then you can use a nice modern cable change Focus box.

Rick

 

I made a bracket to use the original mount to inner wing and then made stabiliser bars with poly bushes in from where the original gearbox cradle mounted to, front and rear. On an xr2 but would apply to a mk4 escort and mk3 could use modded original mounts.
Gary's mount is much smaller than the original mount I've used though, so use that one

 

you wouldnt even notice it tbh if your using the rod type MTX, cut the piece knock it back and drop some welds in to strengthen up, then prep with the filler and paint

 

aren't the mtx with front starter rod change anyway?

you fitting to Cvh rob??

 

Yes CVH mate, tbh i'll probably look for a rod change cable clutch box. But using Garys mount in an option, the inner wing is man enough to take the mount reliably i take it?

Rob,

 

i`m thinking of going the same way mate. bought a 6 sp getrag box not knowing about clutch and flywheel issues!! :doh: that`ll be up for sale on egay soon.

bc gearboxes dont like how i drive i think? got through 3 so far. had present box fettled slightly with uprated bearings. see how it goes but cant see it lasting once i get the power up. whats the life of the mtx like. mileage wise?

 

you weld it to the chassis leg mate

 

kind of jumping onto this thread, but can anyone explain what to do when mounting the MTX in a mk3 fiesta ?

havent got as far as mounting engine and gearbox in the bay so prior knowledge would be great !!

Cheers

 

its piss easy mate chop a small section out of the chassis leg plate it up weld a mount to the inner wing ect

can you weld?

 

+driveshafts and a stabiliser bar to the rear, electronic speedo if going frs route. cable changer, hydraulic clutch also, but depends on which type of mtx75 box you go for.

 

yep can weld so can do that. dosent sound to bad at all to mount it.
which type of Mtx would you recomend. ?

driveshafts are my next issue, what ones should i use ?

cheers for the quick replys, appreciated

 

i'd recommend a FRS one, got the ATB diff in it, but you will need a new speedo (stack ones are only Ł180 :blub: ), then hydraulic clutch conversion, could be done relatively cheaply though. then there is the clutch, a focus rs setup would be alright with a 2.0 zetec flywheel (or focus rs cover, and cosworth 6paddle with the centre machined down a little)
that then just leaves driveshafts, sleeved are ok, work fine for Gary, or custom made ones i went for, cost me Ł160 for the shafts and a donor pair of 2.0 zetec shafts for cv's and intermediate shaft.
all in i think my setup cost me Ł1600 in all, that's:
FRS box Ł600-26k on it
FRS cable shifter with FRS knob Ł180
FRS master cylinder with hydraulic lines(free for helping get box out of car)
engine mount one standard the others were 316stainless tubing with poly bushes i knocked up circa Ł40
clutch Ł200
flywheel Ł40 brand new with new standard clutch setup
speedo Ł178 (also bought matching speedo too for Ł240)
shafts Ł220 (Ł160+Ł40 for mondeo ones+xr2 cv's that i had already (it's in an xr2), new boots Ł20)

little bits like wire for speedo, oil and welding wire/gas etc. for inner wing chop.

could be done cheaper though if you had time and access to machinery.

 

excellent info cheers.

sorry i didt give you this info before, just a couple more questions if you dont mind ,
i have a brand new atb diff that a picked up off ebay, which MTX box is best to fit this to ?

i have got the dials from a focus rs so was planning to them

i have a 2.0l zetec clutch and flywheel, is the clutch man enough for 220 hp or will i definetly need an uprated item like you suggested ?

think i will make sleeved shafts to save a little money.

now some of the other parts i need for the conversion now

thanks

 

Hi guys, I've fitted my mtx but still having problems with gear change, box is all good but when changing reasonably fast it won't go into 4th or 2nd too well

1st, 3rd and fith is ok, do you think the rods need slitly adjusting?

Also the ball and socket joint at the bottomof the gear lever is quite worn, with these two fixed will it be better? Or other issues?!

Cheers!

 

FRS dials need ecu to control them sadly, box is best to be a focus rs one due to bellhousing being better for focus cover fitting as standard zetec clutches won't last at all. standard zetec clutches aren't designed to run on turbo engines, the torque will be massive.
you could run an rs2k box and fit the diff to that, clutch could be awkward as the bell housing inside is a little smaller.
personally i'd just find a FRS one and flog the diff, shot peened gears in the FRS ones too

 

1.8 mondeo box , ratios are almost the same as focus rs box.

 

cable or rod change?
sounds like rod or cables need slight adjustment.

 

a few pic's of one in a mk3 fiesta for you.

 

It's a rod change cable clutch deisel box with atb

 

wat is the diff in bell housing sizes between mondeo and frs? will i still be able to use uprated frs clutch?

 

yes clutch will fit in the mondeo bell housing i have done it.

 

cheers for putting the picture up crazycage clear now about the mounting for the gearbox, what MTX did you use ?

xr2wishy thanks for all the info will need to invest in a decent specced clutch.

Craig

 

ah thats good picked up a derv foucus box on sat, so swapped the bell housing over with my spare mondeo 1, just got to deside on ratios and fit the diff. cheers

 

hi guys. im looking to re build a 2.0 black top and put it into my focus 1.6se, can anyone tell me if the mondeo 2.0 is the same just switch over the inlet manifolds as thats the only visual difference. and are the wiring looms the same?
any help would be great...

 

You can 'make' a slightly shorter MTX gearbox. Lee at Devil Developements did this when he fitted a diesel Focus MTX box to his Mk6 Fiesta. He made all the mounts etc... but when he got hold of a Focus RS box he found it was slightly longer and fouled on the inner wing.

In the end the end he swapped over the ATB into the diesel box as he plans on cracking 200mph with it (currently building a Nikasil linered 600bhp Zetec turbo!).

I was under the impression they were all the same dimensions but apprentely not!

 

I just fitted a RFS ATB with RFS flywheel into a RS2000 casing. Very minor grinding of the bellhousing was needed.
