the aim of this thread is to educate those of us relatively new to cossies what can swap between the cars either between the cossies or thier respective base models.

Some of you might think this is noddy stuff, but not everyone has decades of cossie experience so it would be beneficial to write down some of the basics for newbies/recent cossie owners. Also useful for knowing what goes between what for conversions etc.


these are my questions so far....

Engine
other than obvious differences like 200/205 block, what is interchangable between the YB lot??

Thats kind of answered in individual sections which you have listed below, as they are basically the same engine in respect to internals.

heads?

Think the heads are interchangable, 4x4 was revised and has better water jackets etc.

cams?

Think they are different, and you need a spacer if wanting to fit one to the other, IIRC it's 4x4 to 2WD.

pumps?

camshaft drive/auxialliary drive?

99% they are the same, sure Pinto is as well!

ancilliarys - alternators, PAS, dizzy, aircon etc etc

The alternator on some 4x4 models was moved to the nearside and the PAS to the offside (Maybe for Air con models?) in any case the alternators are the same that being a 90A Bosch item. Dizzy is the same I think, aircon was only a 4x4 option (In the UK at least)

manifolds?
Sure they can be interchanged, 2WD is better if aiming for higher power.
turbos?

pipework??

cooling system?

4x4 cooling system is far better than 2WD, stat housings are different, as are expansion tanks. 2WD NLA and command crazy money second hand, 4x4 still avaliable from Ford for circa a reasonable £35

oil system?

Transmission

Diffs: I know there are different sizes between 2wd/4wd but what can be fitted to what? ie can a 7.5" diff fit a 4x4 beam with standard prop etc etc

As mentioned below

also are some non cossie diff parts compatable?

If you can find a lesser model with a 7" LSD then yes.

driveshafts, CV's etc. what bolts up to what?? which is stronger etc?

2WD shafts are bolted with T50 torx screws to the diff and hub, 4x4 are splined like lesser models (I think)

gearboxes. Whats needed to swap between 4wd/2wd etc.

Suspension

dampers/springs

4x4 springs are different (4x4 has higher ride height), dampers are also different (4x4 front struts are thinner or thicker can never remember which way round it is, thus are NOT interchangable) All 2WD Cosworth is interchangable, although being petty the Saph does have slightly different damping rates to the 3DR.

rear beams/subframes - scorpio cossie, 4wd, 2wd, etc

2WD has a unique beam and so is the diff (7.5") lesser models and Cosworth 4x4 are 7", they are interchangable however, both are LSD'S. I believe the Granada/Scorpio Cosworth to have the same diff, and possibly the beam as well?

Some even sand the diff casing down or cut and reweld one of the lugs where the diff mounts to the beam, in order to fit the larger diff.

anti-roll bars

Escos rear is 24MM, and is the widest one, the 3DR or 2WD is 16mm, in any case I imagine they are all interchangable being they all are the same cars mechanically?

On another note 3DR trailing arms have a different roll bar mounting point to other models.

TCAs

Saphs are the same in fact I think all models may be the same, 3DRS are different.

hub carriers.

Brakes

3DR/Saph, of course have the same hardware, that being 4 pot fixed calipers up front and 283MM VENTED discs and single sliding calipers at the back with 278MM SOLID discs.

4x4 has vented discs all round and the discs are different sizes (278MM at front, and 273MM rear), and I think single sliding calipers all round, so worse than the 2WD models! I don't believe you can fit the 4 pots onto a 4WD as the offsets are massively different! Alot go down the FRS route, but you need brackets making up etc!

You can uprate a 2WD rears to that of the 4x4 but you will need the calipers as well, due to the discs being wider!


Steering

Racks

At a guess I think the racks may be the same, 2.4 turns lock to lock for 2WD anyway.

PAS

Believe the hoses and possibly reservoir are different but pumps to be the same?

linkages

Same I would imagine?
columns etc.

Same I would imagine?

just the obvious ones so far, then things like which jag diffs fit, what other ford parts can be used etc.

3dr cossie front suspension arms are different to 2wd saffs and 4x4.

Front and rear calipers on 4x4 saffs are different to the 2wd n 3dr cossie.

Im sure the anti roll bars are thicker too.

Front shockers are fatter than 2wd saffs.

All of which I mentioned above, bar the trailing arm bushes, yes Cosworth have bearings, lesser models are rubber

Saff 4x4s had different dash to the other cossies. 4x4s have a small glove box storeage bit on the drivers side.The center consoles are different too.

That as well as facelift models and so 4x4 also have adjustable steering, this type is known as the "Hooded" dash.


4x4 saffs have bigger intercoolers than 2wd cossies.

Correct, 25% larger.
