Diff on a S1 (1988)
Discussion
Hi All.
I know about the scraped knuckles and swear words, I have been stripping it down for a rebuild, we were hoping to have the body off in a couple of weeks or so, I have been looking at a few LSD units but not sure what they will take in BHP, we are putting in a Toyota quad cam 32 valve V8, I had looked at the Lexus diff but don't think the driveshafts will work without a lot of trouble.

Are you sure that engine will fit?
The Rover V8 is a popular engine because it is so narrow across the heads - I can't see any quad cam engine ever being narrow enough to fit.
I've got a V8S and the engine is very tight under the bonnet.
Thats before we start the discussion on the rear trailing arms & mounts!

Hi.
Yes it will just fit with a few slight mods to the exhaust manifolds and new engine mountings, I have to loose the aircon pump and power steering pump, re locate the alternator, there is a kit to loose the viscos fan and mount the alternator slightly to the right of where the fan was, other than that it looks a go.
The brakes are disc at the back and we know we will have to do some work on the back.
A nice project, the engine is only 176 Kgs all ally so the weight should not be a prob, like any good project I am sure there will be a few other things to mod.
My son has a rover V8 in a landrover so we have looked at it from all angles, the support between the suspension is welded on the S1 but on the V8 is bolted, we think we will have to do this mod to be able to get the engine in and out, I know there is lots to do to make this fit.We have been looking at your V8S Rebuild begins, so we think is is possible

You can change the diff for a LSD one if you are so inclined, its a bolt out bolt in swap with a few scraped knuckles and swear words in between.
If you go for the Ford LSD Diff watch out for the diameter of the output flanges to the drive shafts... The Standard is 100mm Dia but there are some Diffs with 108mm dia flanges and different PCD's to the drive shafts, the stub-shafts are not interchangeable either... dont ask How I know.But if anyone actually wants a 7.5 inch Ford LSD Diff with 108mm Dia Flanges I know where there is one

ps its a pretty simple and clean job as I recall...
Sounds like a very interesting transplant.

They always said with the early S chassis that the rear trailing arm mounts were not suitable for more than around 220 BHP. AFAIK several people have exceeded that figure substantially but I dont know whether any reinforcement was undertaken.like any good project I am sure there will be a few other things to mod.

Jack up the rear of the car, turn one wheel, if the other turns in the same direction LSD if in the opposite direction normal, not LDS
...provided that the car isn't in gear at the time... if it is, the other wheel still has to go in the opposite direction... Important check!one other thing to check with Ford original viscous LSDs is if theyve had a hard life, they are often little better than an 'open' std diff. the viscous fluid can get overheated and either leak out of the cartridge or just lose it viscosity. they can be rebuilt/cartridge recharged but its not a DIY job. Bara motorsports in Redditch area are amongst those that can.
if sourcing one second hand, ignore Cossie ones and go for ex granada diffs instead as they are likely to be less thrashed. i know in the Sierra service manual, theres a way of testing them, along the lines of jacking one wheel in the air (out of gear as prev mentioned, and then add a torque wrench to wheel hub centre nut and check the Lb/ft 'resistance'. They give a range in which the resistance must be for it to be considered ok and not need a rebuild.

Hi TVRmadpaul,
I was trying to upload some pictures but how do you post them
I was told the Granada cossi has the 100 flange mounts but not looked at one yet

You have to use a 3rd party site such as Flickr. Upload the photos to that.
Then in the post you need to do the following
[img]URL address of the photo[/img]
To get the URL address ensure you are looking at the main photo in Flikr right click it and view the property page. Copy the URL address from their.
Only know this because I asked the same question a few weeks back.

the IMG format above is
the URL will I assume be in flikr for you to copy and paste - I use photobucket and that adds the IMG bit as well.
Here's my post on how to with photobucket - the principle should be the same.
