What's the differences in the floorpan/running gear?

Is the XR weaker?

What are the differences in the brakes, I mean like the beams, not worried about the disk/caliper sizes etc?

cheers

 

front hubs and rear hubs are different

rear beams are the same, as are trailing arms, gearboxes are the same, altho different bell housing on the V6 XR4x4, rear propshaft is thicker on the cossie, alloyt front cross member is the same aswell

rear driveshafts are different, the flanges are thicker on the cossie,

front driveshafts are slightly longer on the XR4x4, but easily useable on the cossy, as i have done

 

Pretty damn the same then...........

 

hmmmmm, thanks fellas

looks like something like this may be my new car then

also, would it be possible to uprate to Cossie hubs and propshaft (if they're the only real differences)? and if so, how much Ł roughly?

thanks again

 

now you didn't say pre-90 spec stuff

different rear arms, gearbox, diffs, driveshafts, props and everything - nothing the same as a cossie on that car apart from the front proshaft

 

that was only an example 'cos it looked so shite, lol

fair enough then, so I want a facelift xr4x4 then? H-reg onwards is that?

 

anything 1990 onwards will do

and price for changing hubs over - depends where you get the parts, some people sell front knuckles (hubs) complete for Ł35 a pair, but they don't realise their value - which is nearer Ł200 a pair

 

one like this maybe, it says '89 G, but looks like the later model to me?

http://cgi.ebay.co.uk/ws/eBayISAPI.d...6420%26fvi%3D1

 

that sounds fine to me. Still cheaper and easier than buying a Cossie donor vehicle just to break

 

thats an 89 spec model - different rear arms again

does look a clean motor tho

 

now this is 90-spec I'm sure. well, unless someone's changed the wheels, but it says 1990 anyway

http://atsearch.autotrader.co.uk/www...00608224985736

 

that indeed is 90 spec

however, about 400 quid overpriced

 

it's at a dealer. Wouldn't wanna pay that much, just the only post-1990 one I can find on either auto trader or E-bay atm

 

Swapping hubs over is not that hard. I changed them over on mine to cossie 4x4 hubs, discs and calipers.

 

that's what I was hoping to hear

 

is this a 90-spec?

I'm guessing no, but only 'cos of the wheels really

The rear arms are different as the cosworth versions have spherical bearings fitted where as the xr4x4 used rubber only - they are though physically the same - so not a problem if you are planning on poly bushing them.

The rear props are the same, its the 2wd ones which are thicker.

The casings of the 2 litre post 1990 MT75 is the same as a cosworth but the ratios are different, where as the ratios are the same as a cosworth on the 2.9 but the case is different.

The diffs on the 2 litre are 3.9 but 3.6 on the 2.9 ( same as cosworth)

The rear hubs/ bearing carrier are smaller on the xr as they use a smaller disc but the calipers are the same as 2wd cosworth

rear shafts are the same, as is the beam, but the arb is thinner

Front hubs wont allow cosworth 4x4 discs and calipers to be fitted and the rack has a bigger turning circle

mot failure 2 litre xr4x4 sell for around Ł200 but contain over Ł600 worth of usable spares so make a good donor for a cosworth project

 

sounds good

just need Cossie hubs on top of a post-1990 XR then pretty much

 

the ratio on the cossie 4x4 box and the twincam 4x4 box are exactley the same - i know this as a fact, i have a twincam box in my taxi

 

they may appear the same on the road, and the boxes are a direct swap but they have different ratios fitted

 

also if you go for it get a 2.9 or 2l model as these are efi and most of the management just plugs up behid the battery

ive done this conversion years ago to my old one

alls i did was poly bushed it, changed the front and rear hubs to cosworth items so i could run cosy brakes

engine and gearbox are a direct fit as with everything else in the engine, even the holes for a 500 cooler

props are the same as well

took me 2 weeks on my own to do mine

the only bit that is a bit diefferent is trhe exhaust as its longer for the saf so the tail pip sticks out a bit more but hardly noticeable

also if you get a 2l model you will need to change the accelator pedal aswell as cables are different

 

Hub wise when fitting 4x4 cos brakes ( which I have!) to my xr4x4 do I need the hubs and the hub carriers?? ie the bit the wheel bolts to and the bit the strut goes into.

steve

 

no

you just need the bit that the strut goes into mate

all the carriers are the same

 

I thought the bit the strut goes into was called the carrier?

confused now, I think I need the bit the strut goes into, correct?

cheers for the help BTW,

steve

 

sorry yes mate

bit tired didnt ralised what i wrote

you need the carriers the bit that the stut goes into yes

the drive flanges what the discs go onto are all the same if that helps better

 

nice one cheers m8, will just need to find some now!

steve

 

worth the upgarde to be honest mate

as standard xr brakes are the same as s2 turbo at the front lol

im lucky enough to have aset but ill be using them for when the 24v goes in to it in a couple of weeks just carnt decide whether to have a 4 pot 330 or just run standard cosy brakes

 

I have the cos 4x4 calipers, disks just need the hub carriers now..
thanks for the info I am also going 24 v with mine over next winter so when you do yours tell us the story of how it went..
cheers,
steve

 

will do mate

will be doing a underside resto at the same time so will be a post in the resto soon

just waiting on another 4x4 to come so i can rob the bit soff it for transmission as mines just a 2L so parts arnt compatibale

 

Remember the XR steering rack although the same ratio as a cossie can a little further than a cossie which is restricted by about 0.4 turns or something and you do seem to get a grinding noise at full lock sometimes.

that one is no good then either?

it says 1990, but january registered plus has 88/89-spec rear spoiler

it's the 2.9 though

 

but then this one is regd 1991 and has what I thought was the earlier boot spoiler
