some of you know i have been mulling this over for a while....well im getting started!!! yay!!!
(this is gonna be soooo expensive!)

i am planning to use escort rs2000 4x4 running gear. not easy as only 600 were made to start with and bad maintenance usually means the transfer boxes are knackered

how it works;
transverse gearbox but diff sticks out behind the engine and you slot a transfer box over it (the shaft to drivers wheel goes thru the centre of all of this and works as usual)
the extended diff casing drives a viscous unit (looks same as the unit inside a frp / rst lsd??!)
this has a cog around it which drives a gear behind it, that gear has a 45degree bevel gear on it which runs against another 45 on the propshaft....turning transverse power thru 90 degrees and onto a propshaft to rear wheels

its very similar if slightly less beefy than a mitsi evo

to keep the 0.8 litres (??!) of oil cool inside this box i have been told to plumb in a cooler and pump...should stop any issues

im wondering if i can send off a 4x4 diff and get quaife to machine or swap the entended casing onto an atb diff

problems mounting the transfer box; subframe will need chopping / remaking, gear linkage needs to be upgraded to cable as no room for rods, custom exhaust

transfer box mounts to mtx gearbox...bigger than ib5....thats a whole seperate issue including upgrading it to hydraulic clutch and fitting a shorter , more powerful engine... ;-)

prop shaft....'should' be room....if i remove 1/2 of one box section between seats and plate it to the next one over...keeping strength...and crucially; not messing with interior carpet!! IT MUST LOOK LIKE FORD PUT THE WHOLE THING TOGETHER ;-)

this is the bit im working on right now; fuel tank. just bought one with channel for prop shaft....have a spare puma at work im chopping back to floor pan / engine bay....seeing if it will fit or whether im having a custom one made & just nicking the fuel sender / scavenge pump (tank has 2 sides and 2 pumps!!)

after that im starting to acquire parts for rear suspension; want the frp to have independant rear sus this year with everything in place to mount rear dif. its an ali cradle which bolts straight to boot floor....bit of plating / re-inforcement and should be really easy....dont know if diff is offset to one side or whether escort is wider than an frp but will have custom ali / titanium links with rose joints eventually....

want ali hub carriers; any ideas? iv known people make their own from tubing etc

bought so far;
gearbox with knackered diff. will use empty case for dummy build / designing chassis mount and diff to play with / send off to get fixed or as template for a quaife atb.
tank, pumps, straps....to test against spare puma floorpan / use as a templete to have a custom one made for frp
trailing arms...to build up against swing arm when i get all the other bits & send off
to have lightweigh, adjustable, rose jointed copies made.

to buy; lots!!!

want to use frp type rear brakes / discs however im very tempted by the ali vw calipers on golfs etc...look very similar but a lot lighter.
 
Worth reading "Dave2302" project on PumaPeople. He's just finishing building a wide-bodied Puma with 4-wheel drive, 24V Cosworth V6 Turbocharged engine and roll cage etc, that he's going to rally. Could be a good contact for you. He used to be a specialist transmission rebuilder and ran his gearbox firm for 25 years.

Some of his past builds include a 24V 4x4 Cosworth Sapphire, a 3.9 V8 TR7, 6.2 litre Chevy V8 Diesel powered Range Rover Vogue and a spaceframe Fiat 500 with 6.6 litre Smallblock Chevy V8 + NOS.

Plenty of pics:

cool, cheers

Warren; yep all rs2000 4x4 bits. picking them up tonight, guy is stripping another car so may come home with cradle etc too :)

remember a guy who did this to a white mk3 fiesta xr2i but the magazine it was in didnt do one pic of the underneath!!! and that was mondeo 4x4 gear which looks very similar but beefier and heavier...he got it all to fit tho
 
Had an awesome day.....went to pick up the 4x4 gearbox, petrol tank and trailing arms i won on ebay...was gonna be happy buying a bit here and there and working on it slowly....but when i got there he explained he had sold all his 'spares' and was now stripping his actual car....and would i like any bits!!!!?

long story short i drove his car, all the bits seem perfect, will be worn but hey.....im getting the whole back end with all suspension, brakes, struts, diff, carriers, prop, drive shafts, gearbox AND transfer box for £550 delivered to my house next week!!!! iv seen transfer boxes on their own sell for more than that!!!!

and i have discovered the whole lot just bolts straight onto the chassis rails under the boot floor! wouldnt it be nice if the puma ones are in the same place?!
 
jacko remember to get the guy to measure the distances of the track control arm mounting distances and importantly the strut top distance. the actual mount in the shell is the same as a rear beam mounting pick up but on an escort there may be some dimensional differences. same with strut top distance which will effect camber.

theres not much in it though. I had all the measurements a couple years back but lost them!!
 
dammit, forgot about that! meant to take a tape measure too... oh well even if i forget about it again theres plenty of escorts to measure at the scrapyard :) not the end of the world either as im gonna make it all fully adjustable :)

hey warren; whats the multiplug on top of the mtx gearbox for??!
 
yeh, will get some piccies up soon....

bonus! just discovered mtx box is no longer than ib5! makes my life easier!
 
my test mule / 4x4 jig; a cat d 1.7 puma, front cross member has been pushed back and twisted but i can cope with that when doing measurements / test fits.

kids at school thoroughly enjoyed ripping it apart and quite a few people on here have benefitted from the parts :)

will be chopped back to a floorpan with strut tops and engine bay so got more to chop off passenger side and windscreen / frame are going too

you just need to make things within a couple of inches or so. As long as your adjustability gives enough movement to correct any geometry problem of a too narrow set up etc then its not a problem.

3 pin multi plug??

you should have a gearbox multiplug for reverse switch and also maybe a speed sensor.
