anybody know if this will fit an rs turbo? as i have just baught a recon one for £100 delivered. and forgot to ask about the splines and size of input shaft. i am now worried if wont fit my clutch and or flywheel!! oops

 

Im pritty sure they do.

 

Shorter ratios, no LSD and not much stronger than standard box if at all IIRC...

 

if its out out of the later van like a v reg van then no it wont as the splines are bigger was told they run the bigger bearings too
as when i turbo'd my mk6 van i had to use the s2 friction plate and the diesal pressure plate and bearing,which is working really well at the min

 

thanks for the quick replys.
i have an lsd that can go in at a l8er date, if i can be bothered. but i have just broke 3 boxes one after the other, and am now fed up!! so i baught this as it comes with 1 years unlimited millage garunte!!!! there gonna reget that lol!!!

 

i have a ap 4 paddle at the mo, so thats not good news
althought it does annoy the shit out of me in traffic so a normal clutch would be nice, just depends how long it lasts?

 

Yes they are!

 

Also make sure it's not got a rear mounted starter motor.

 

The box will have a larger main shaft and bearing also the cover plate will be different using a flat release bearing which makes it much nicer for gear changes. The AP four paddle clutch will still fit as its the same flywheel your using and will take around 230bhp.

 

spot on!!




gear box has turned up, starter in the right place, clutch fits!!! only problem is it has no release bearing fork fitted or speedo drive. it looks like the bc ones might fit so will see.
then we will see how long it lasts before it breaks!! lol

 

here is the item number from e-bay if anyone is interested. 170478860290 . i made a best offer of £90 and one with £15 postage. and it came the next day aswell which is good.

 

hi, ive just had one of these boxes and was wondering if anyone knew what year cluth kit i would have to get as the mk4 clutch release bearing has a smaller internal diameter and wont fit on the box which has a metal sleve where the bearing sits, so i need the larger bearing but dont know which year or where to get one the right size any help would be useful thanks

 

Whatever car you got the box from mate, just get a release bearing for that.

 

i just orderd a mk5b release bearing for a ford escort diesel van, they asked what gearboxwas fitted as some still used the earlyer bc. i said ib5 job was a gud un cost me about £15.
also the rst clutch was fine and didnt need changing

 

RSargie, i have a RS1800 fiesta on a 95. gearbox is whining and ive been told a good place to start is the release bearing. where did ya get your bearing from?

 

robbie is the noise there when the clutch is pressed or not pressed?

 

well it started as it would whine when the pedal is up and i let off the acc or attempt to slow down. drop the clutch it stopped. or give it a lil bit of gas n it would stop also. it is now also popping out of reverse, and bitty in 1st gear at say traffic lights. and might i add any help would be really really appreciated

 

it isn't the release bearing, the gearbox needs a rebuild from the sound of things, replace clutch kit while box is out of the car

 

You could possibly use your paddle clutch with this box as its the same but the earlier type and im pretty sure it will fit.

that is the exact same gearbox i have baught for my car had it in over 3 months now and its never missed a beat!! comes with a years garuntee as well. and its got good ratios for pulling away as well but it tops out 135 ish at the limiter in 5th.

 

id get it checked before you start buying release bearings.

 

How did you fix your speedo issue?

Rob,

 

i put 1 of these on my cab a bit ago as i was sick of it getting through bc's and its much better, as already mentioned the gearing is a fair bit shorter and you loose some top end, but it gets ther quicker. My lsd bolted straight into it as well, i had the same problem with the release bearing as these diesel ib5's have a metal sleeve where the bearing goes on, if any1 needs the part number for the bearing then i can dig it out?

Only problem i came across with mine is that it hasnt got any reverse lights anymore as the reverse light connector is different, its an easy fix if you just want to swap the connector over if you cut a connector off a newer loom from something with an ib5 box.

 

Did your old clutch fit in the box ok?

 

the bc top fits in, just baught a new speedodrive and roll pin from ford. apparently there colour coded and its the red one you need.

yes old clutch is fine im running a standard rst cover and ap 4 paddle. and the ib5 release bearing. i carnt fault it. feels much better on the road than a old 100k bc box.

 

Right, so essentially this box fitted straight on, every thing worked and you didn't have to adapt any thing? (other than fit your speedo drive).

Any one know if the internals from a sport KA box (hoping karlos G can fill me in) will go in this case along with an s2 LSD...... Changing the ratios...

Cheers

Rob,

 

yes sport ka ratio's fit but they are far too short for a turbo'd engine, i'v tried them before on an old zvh ka that i stripped, normal 1.3 ka ratio's on an rst lump were ideal i thought, on just a 200bhp 1.8 zvh with an omex limiter set at 6200rpm mine did 62mph in 2nd, 90mph in 3rd, 125mph in 4th, and never got to the end of 5th, all of those were on gps, and it kept the 0-60 times down as it saved an extra gear change which is needed if you use sport ka ratio's.

And yes an rst lsd diff bolt's in and just uses one of the ib5 diff bearings as its slightly bigger than the bc bearing.

 

yes absolutly no mods required i used my bc speedo top bit, clutch arm & fork, ib5 release bearing and speedo drive. i havent fitted a lsd diff yet tho as i am waiting to buy a new one. but as they say if it aint broke dont try and fix it!!
the car is driving very nice at the mo and the last thing i want to do is pull the box apart and in not feel like it did before when i put it back together again!! plus its still under garuntee for a while yet.

 

Yeah as said they will fit, but you'll need to machine the casings to take the bigger bearings, or maybe use the stock BC bearings but then essentially what you have done is taken the stronger IB5 box and made it weak again, it's the bigger bearings and reinforced casings that give that little bit extra strength.
Sport Ka ratio's are just like XR3i ones, nice and close! The 1.3 Ka is loooong like a diesel box......... but it's what you prefer really.

 

The gearing in the none turbo diesel box's are not long they are shorter than a standard rst. mine soon whips throu them at faster than it did with the turbo box. and is quickly maxed at the limiter in 5th

 

This is an IB5 box tho? Would they need machining for larger bearings and should already have the stronger casing? the mk5 diesel box should already have them no? Are we talking about the s2 lsd or the sport KA gears? Sorry lol im lost!

Rob,

 

Shit sorry I thought you said would the Ka Sport internals fit into a S2 box! lol
Ignore my post, yes everything will go straight in!

 

Lol cheers fella, think i might have to invest in one of these boxes in the short term,

Rob,

 

Apparently the rover 25 has an ib5 box too. Does anyone know which one is needed as I am considering changing mine soon too?

 

Actually the one in that link looks pretty good for the money, I take it this will go straight in using a new ib5 release bearing but how do I fit the LSD from my box?

 

5th gear puller and regular tools is all thats needed to fit your LSD, oh and some new IB5 diff bearings.
Box is a piece of piss to strip down!

 

but if it is a recon box as per the link then surely it would have new bearings and not need anything apart from the correct release bearing?

 

You asked how to fit your S2 LSD in...... it has smaller bearings so to fit it in the IB5 box you will need new ones, unless you can get the old ones off the open diff of course.

 

It says recon, but for that price i really wouldn't bank on it too much.

Rob,

 

i rang them before i baught mine and they seam genuine, they have been trading for a long time. they said they replace synchros as well. and plus they give you a years garunte with unlimited milage. i even told them it was going in a rst and not an escort van and they said no problem. you also get a proper vat recipt as well form the company not just an ebay one.
