RRC and disco differences

[ronette]

sorry for a stoopid questions to people in the know, fairly new to the rangie world.
I have a 92 RRC vouge se and wondering what engine and running gear is the same as a disco.
i have been offered a 96 disco and a 92 disco CHEAP!!!
doing my head in trying to find on the net
mainly want abs, cv joints, bar work, etc
any help greatly appreated

RR and disco are built on the same chassis, so much is interchangable. Are the Disco engines petrol? If yes, and unmodified, the earlier (92) will have the 3.5; by 96 this engine had been superceeded by the injected 3.9.
What engine is in the RR, 3.9 or 4.2?

With regard to the disco diffs, the differences that we found RRC vs Disco; the brake calipers are different - the bolts holding them on are different sizes, found this out the hard way, think its also twin lines on the RRC vs single lines on the disco. The hubs on the disco are shorter than the RRC

RRC probably has a metal petrol tank and the disco a plastic one.

I'm sure other will know more

The axle flangers are different on a rangie to an early 10 spline disco
Rangies have narrower flange bolts while disco's have thicker bolts.
So to swap axles from a rangie to an early model disco1 you will either have to drill the rangie flange holes out or swap the hubs over.

There is a post in The Good Oil forum on this,,

a (ahem) warm 3.9L

Chech that the radiator reserve tank is not split.

The simple answer is not a lot is exactly the same, but large chunks will fit.
A '92 RRC Vogue SE should have multi belt 3.9, ZF auto, viscus t/case, air suspension & ABS brakes.

From the 1992 Disco (is pre-update, sometimes refered to as a 200 Disco, especially if a diesel) you can swap:

• Engine, if its a V8, but it should be a 3.5ltr
• Auto, if it's an auto. If it's a manual, it should be a LT77 (reverse up to the left, next to 1st), not worth thinking about swapping the RRC to manual.
• LT230 transfer case (a bit of mucking around to do) if you want to convert the RRC to have a manually locking centre diff - makes a bit of a whine and clunk, but is better for serious 4WDing - if you remember to lock it.
• Springs & shocks, if you want to get rid of the air suspension.
• Brake booster, master cyl (will be a 4 port = 2 hoses on each front caliper) & axle assemblies if you want to get rid of the ABS - although that might not be legal?, and the RRC probably has ventilated front discs which are a bit better (although can fill up with mud) than the solid Disco ones. Diff centres should be 10 spline, RRC might be 24 spline?

The RRC fuel tank will be a plastic one & is different to the disco although it will bolt in, it has less capacity due to the shorter body.
Most of the interior from the Disco will swap over to the RRC - a lot of work & why would you?.
None of the panels will fit, but window switches, mirrors, outer door handles (except they are black) & lots of other little stuff will fit, as might (?) the winscreen if you can get it out in 1 piece.

From the 1996 (update or 300 series), you can swap:

• the engine - it is a 3.9, but with serpentine drive belt - this is a 'cleaner' configuration, but if the belt or tensioner go, then everything stops, rather than just whatever belt broke with the multi belt set up. You could run the serpentine belt set-up, with some wiring, A/C compressor & radiator changes, or, all the multi belts will fit onto the front of a serpentine block, but you need to change the timing cover & all sorts of brackets & bits across.
• auto if auto, manual will be R380 - could swap into the RRC if you wanted to, pedal mount unbolts off the firewall, a bit of work but doable with patience.
• LT230 transfer case as for 1992, although a 1996 might have a cross drilled t/case input gear, which is better than the earlier car. Also might have a rubber coupling on the tailshaft at the rear diff, which is not as long lasting as an earlier car uni joint.
• springs & shocks as per 1992 car
• Brake booster, master cyl (will be a 2 port = 1 hose on each front caliper) & axle assemblies if you want to get rid of the ABS - although that might not be legal?, and the RRC probably has ventilated front discs which are a bit better (although can fill up with mud) than the solid Disco ones. Diff centres will be 24 spline, RRC might be 24 spline?
• the complete dash & most of the interior will swap - a lot of work, but you do get a nicer dash with a glove box & all the heater & A/C pipes in the right spot if you also do the change to serpentine belt. I think the RRC front seats with armrests won't fit with the update console?
• much of the door hardware as per 1992 car, but the mirrors are bigger, and a worthwhile upgrade.

Unless really really cheap, and you want to do some 'upgrading' of RRC spec, then probably better to find a cheapish RRC from 1991 - early 1994 as a source of easily swappable parts.
