tried a search on here and no good

So am I right in thinking I seen on here someone saying they are good for about 250bhp max

Anyone that knows about these do you know

Cheers

the torque rating for the box is about 150 nm(not 185 as previously stated) unless you have one of the more recent uprated French ones which is about 230nm (M sport have a couple of the internals of the french boxes on evil bay at the mo, very little money)

Ex-Finesse

Uprated French ones?

No chance these are being confused with the MTX75 gearbox is there? This was used in the diesel escorts, and many cars on the continent are diesel, so it would figure....

An iB5 won't last long with 200bhp / lbs. Couple of thousand miles or so unless driven really carefully.

MTX75 box should handle an extra 30bhp / lbs.

wayne thomas

No they're not!!! the MTX is built in Cologne Germany, there is a heavier duty (greater torque) rated iB5 box currently being manufactured at the plant in Bordeaux France

Ex-Finesse

Never knew that

You say currently being manufactured... so does that mean they were never fitted to Escorts?

Can't see why they'd bother with different gearbox specs given all engines are the same

wayne thomas

Correct they were never fitted to Escorts. The 5 speed MTX is an extremely expensive box to manufacture in comparison to an uprated B5 so its purely cost driven and will utimately result in the demise of the MTX. Which for the record is rated at 250 nm

david

Larger mainshaft bearing than the BC boxes so should last a bit more though it does depend how you use the box. If your hard like I am and kill them often then theres not much point in my opinion though Bernie and others may have better experience

Ex-Finesse

Ok, now I'm with you I assumed you meant some French escorts had uprated iB5's

Anyway, do you know what cars they are fitted to over there? Not realy after one, just out of curiosity

david

total shite.

Ex-Finesse

So there were 2 different ratings of iB5 available in the escort?

First I've heard of this.

The same basic 'box is still used in new Fiestas, including the ST so I could understand if that had some stronger internals, but not the old mk5/6 sheds

Apologies to D19STE for this off-topicness

I still say 250bhp through an iB5 is living on borrowed time

david

2 different ratings, I honestly dont know.

250 genuine with a decent torque figure will kill any std ford fwd box bar the mtx75 which will handle a good bit more from what ive heard from good sources.

From experience the mtx is FAR stronger than both the BC and IB5 boxes.

It's Czech Mate

st170box is a getrag rated box at 330lbft rated higher than the mtx75

david

Sound

do the focus/mondeo ST share the same box do you know and what diff is in it ?

wayne thomas

david given that they stopped manufacturing the escort 7 years ago and have only been manufacturing the uprated iB5 transmission for that many months I'd be quite surprised if any had made their way into an escort !!!!

D19 STE

Dont worry about it mate its good info

wayne thomas

The box in the st170 is an MMT6

wayne thomas

I'm fairly sure that they're different boxes but would need to check, I think the Focus is the volvo derived M56 where as the Mondeo is a Ford box.

It's Czech Mate

It may well have that 'name' but its still a getrag box rated to 330lbft........its the same as the minicooper s box

well if it helps, when i had my ol 2.0l on bike throttle bodies it was running about 180bhp+

first gearbox lasted a month before i destroyed the diff

second one lasted all of a week so i broke the cunting car



proof?

ok

James

lmao, thats fucked that is!

the mk3 mondeo diesel six speed is a mtx75-6 or something, it's a mtx75 with six gears. This is in no-way the same as the old st170 box.

The ford galaxy 6 speed box is a VW box, BUT i have heard it can be made to fit a ford as the bell housing isn't that much differnt, but thats all i know.

Ex-Finesse

Do you know any more about this box?

Does it share any other similiarities with the MTX75? If it's the same bolt pattern, shaft fitment, etc.. it should fit in place anywhere an MTX75 does!

Ratios might be a bit fucked though

James

i really don't know it would be interesting to find out though.

I ran an IB5 with 185 BHP / 200 Lb ft for 6 years and over 60,000 miles including track days and sprints. Still going fine.

Another IB5 has been coping with 270+ BHP and similar Lbft torque for the last two years on sprints (double entered) with road mileage as well. Note that in this instance boost is controlled in first and second gears to reduce effective torque.
