i was advised a machined cosworth six paddle and focus rs cover would be fine for over 500bhp.
however i used a second hand cover which seemed fine, maybe not, but what is a good setup on a reasonable budget as i get clutch slip when over a BAR with traction.
i do plan much more power in time (upto 2BAR) and had to turn it down from 17psi which is where i did have it originally but got sick of the slip.
it's all in a mk2 fiesta with a FRS gearbox btw.

cheers

crazycage

you can buy the ap six paddle plate on its own for £200 ,will be fine with your cover.

hmm, i think i'd check the cover over his time then and make sure it's spot on.
i already have a 6 paddle in there, just centre has been machined a little to fit in the frs cover.
i think a new centre is in order then too, not that i need anymore power as it was spinning wheels in fourth at 110 today, madness.

crazycage

in the wet ?

it was a little damp out, not convinced the yoko 539's are that great though either.
it's not that quick really.

i have been down the same road with this, so on our new build we bit the bullet and orderer a sachs unsprung plate with there top of the range cover, it looks the dogs, have a look at our build thread, focused on track zetec turbo

how much is biting the bullet then?

Quick picture of what happened to my Sachs non sprung paddle.......



Admittedly this was in my Corsa though.
If you do a lot of road miles, get a sprung centre which will help avoid this.

nevsrevs

mines only on track, when i ask earlyer in the year about these clutchs got nothing but prays, look alot better than the helix or ap i have run in the past.. comp braking products done be plate and cover for 520 ish,

xr2wishy

i think i'll just take my clutch off and get the cover uprated and make sure it's true.
whack a new paddle in it and it will prob be fine.
got to do it on the "cheap" due to extra mouth entering the family unit in the next couple of months.

studabear

Are paddle clutches worth having relined?

xr2wishy

iTrader: (2)

they can be, not that expensive either, but for time off road i'd buy a new one and get it redone later.

I know this is an old thread revival....

I've finally got the new engine finished (will post some pictures in a project thread) . It's a zetec 2litre, fully built, forged pistons, Farndon forged conrods, area six ported and polished head with big valves and area 6 valve springs

Anyway, I'm trying to find a clutch that will manage 450hp ~ but won't need massive effort to operate on a road car ideally! (but if it does it does)

Has anyone got any suggestions?
A Helix uprated one won't cut the mustard looking at their power rating. Not sure what the best option is without breaking the bank (more!)

studabear

What gearbox are you using?

zetecbeast

MTX gearbox.
Its a kit car so hopefully wont be putting too much of a strain on it as it weighs about 750kg

studabear

I would be looking at ap focus rs clutches perhaps.

zetecbeast

Hmm, cheers. Will that fit the MTX box then? Iirc there is some modification that has to be done to get it to fit? Anyone have a goood (cheap!) supplier for these clutches? cheers

crazycage

What is the mtx out of ?

zetecbeast

Im not sure mate, it is the one that came with the car. In fact its not an MTX in the car, it used to be but the gearing was too long, so it got an escort diesel gearbox iirc.
I will know more when I take it out in 2 weeks time as I cant get any really good pictures of it as its well buried!

Is it worth getting a focus RS gearbox?

I will have to get a new shifter mechanism engineered if so as the gearstick is on the right hand side of the drivers seat and is a bit of a crap design IMO!!!

nevsrevs

ring competition braking products, get a sachs clutch, cant beat them from our experience, and dont bother with a frs mtx, your's should be fine.

zetecbeast

Cheers mate.
What hp do you reckon its good for?

Sorry for the delay. Had a load of hassles but back with the build now!

nevsrevs

450/450 they offer the highest toque level i could find without going over to multi plate clutch.

zetecbeast

Excellent. cheers will give them a call.

zetecbeast

ok guys.
I am pleased to say this project is now well underway... I decided to do it all myself in the end as it would cost a fortune at a project shop and they probably wouldn't do it how I wanted it either..

So, we got the engine out today and did loads of preparation work for doing the new loom.

First big question, what bloody gearbox do I have?? I was led to believe it is a mk5 escort TD van gearbox, and the casting serial number confirms that they were fitted to those. But the diff doesnt seem to do anything when in neutral and I spin the rear wheels...? as in the wheel on the other side doesn't turn, either the same or opposite way?

Here are pics of gearbox, can someone help identify and tell me if Focus RS box, flywheel will fit or if this box handles some power I will just get a clutch kit for it

nevsrevs

Don't look like a rs box sorry, looks like a bc/ib5 will blow to bits with your power plans, had to be sure with the photo as I'm on a phone.
Has it got a hydro clutch?

zetecbeast

Hi mate,

cheers! No, I didn't think its an RS box!!! was just wondering if I can fit one instead and use the custom driveshafts I've got already for the current setup. Really don't want to have to fabricate a new linkage etc (its a rod setup)
I know feck all about Ford gearboxes so need advice about what to do with this one! I am a longitudinal Inline6 bloke for engine builds until now..!

it is a hydraulically operated clutch. I replaced the slave cylinder and it was using one from a mini cooper

zetecbeast

Hmm, it looks very similar to some IB5 box pictures..!!
That could be a bugger. If I replace it what should I replaced it with? I need LSD I think? and focus 1.8 TD box is meant to have good ratios for the 2 litre ZT? will Focus RS box have suitable ratios? thanks

zetecbeast

Anyone?? I need to get this sh*t sorted!!!

http://www.ebay.co.uk/itm/FORD-FOCUS...item1e9cd20ce1

It looks very similar to this??

no, actually it looks like this lol

How to tell the difference between IB5 and MTX box for 100%?

zetecbeast

If I buy a focus RS box what am I going to have to do to make it work?
or can I just use some other MTX box? if so what will have decent ratios. thanks

nevsrevs

mtx is a pretty good box full stop, focus 2.0 or diesel or mondeo 2.0 mk1 and some mk2, all gears are interchangeable from these models.
if you can find a cheap frs box then you got a atb in a mtx so thats a option.

zetecbeast

thanks mate.
But that doesnt answer my question... how can I tell if mine is IB5 or MTX? are there any definitive things? I am almost 95% sure that mine is an MTX which would be a bonus, because I can swap in an RS one with ATB in... but then I will have to get driveshafts modded, speed sensor altered, and at the minute mine uses a shifter linkage setup

Is it easy to custom convert to cable linkage??? ta

nevsrevs

From wat I can see mate your box is a mtx75 out of a rs2000.

nevsrevs

And yes if you get a cable tower should be a easy swap back to cables.

zetecbeast

Cheers mate.
Ive added a couple of extra pictures at the bottom here

https://passionford.com/forum/ford-e...ml#post6586010

They are much clearer!! Thanks again, nevsrevs, my only mate on PF

nevsrevs

I'm still not 100%
Take a photo of the ass end.

Just buy a frs box, stick in the uprated ap frs paddle clutch. Cable shifter will drop in easily and hydraulic clutch is a simple conversion. Only leaves drive shafts to sort and a couple of mounts.
Mine took a decent amount of power, clutch was light and not juddery, box took the abuse.

clairendave

If the slave from a mini cooper fitted then i would be looking along the lines of a getrag 6 out of an st170 maybe ??

zetecbeast

Will do, Im going to take it out tomorrow or monday so will get pictures then.thanks

Yes mate, that's looking like its on the cards

Cable shifter will drop in easy? I don't really know what the mechanism uses but I'm guessing the cable will be the wrong length for my car, is it shortenable or extendable in some way? Does it use rollers on the cable routing or what?
I've got hydraulic clutch already so that's one less expense I suppose!...
ALso, if its an IB5 now, are the driveshafts in the same relative position on the MTX box? (eg so I wont have to alter engine mounts to align with the rear hubs!)
And the starter motor is in different position on the Focus RS casing.... can I change the front of the gearbox casing for an MTX one that has the starter in the correct place??

So much to do lol

Cheers

Not sure I quite follow the logic here mate?!? but I can use a different slave for a new box , that's minor works on the scheme of things

clairendave

I was under the impression the cooper and st170 use a similar getrag box ?

zetecbeast

Ah right, yes I see.
I should have made it clearer but this was the original mini cooper!!!!
I had a major bit of luck getting one off ebay!
