Im goin to rebuild my gearbox now that i have to fit a new clutch and such anyway, so i would very much like to know if there is a way of making the LSD stronger so it dont break when you accelerate(with, unfortunetly a bit of spin). I know that my ERST isnt the strongest around but it has 170bhp and 263nm, but im aming for 200bhp and 300nm or so and then the LSD will fail im told, and i would like to keep the gearbox on and not have to take it out now and then to fit a new(used)LSD just because i want a litle more fun with my funny(very funny indeed)car.

 

check out this months Fast Ford mag (chip's custard 3dr on the front) its got all about LSD's in it page 148

or give gearboxman a shout

 

Change the fluid inside it for a more viscous one.

 

what do you use for your own gearbox and what should i use to make it stronger?

 

DannyDK - I have the full Quaife straight cut close ratio box, it gets looked after and rebuilt several times a year by either myself, or Bernie at CTS

 

Is the used parts form your box any worth?

 

No but I sometimes use them as paperweights at work.

 

Where can I get new or better fluid for my LSD and is it possible to get new plates in the diff? I rebuilding the box this winter and I want to rebuild the diff aswell.

 

who told you that?

 

Anyone rebuilt their lsd?

 

Never bothered changing the plates in mine, I took one to bits once, that was enough, looks impossible unless your very patient.

Fluid usually gets done once a year, either local or at CTS (gearboxman in UK)

 

Have you changed the fluid yourself? Where can I buy the fluid? When you diff is sent to CTS, have they ever changed the plates or is it not necessary?

 

Never found it necessary to be honest.

If you want a different (better) diff choose a different manufacturer.

Do you know how the fluid is held in and whats involved in changing it ?

 

I'm rebulding my box and want to investigate how to rebuild the diff aswell. A new diff at the cost of 500 pounds is out of the question.

This is the viscous lsd unit.


Some guys I've talked to that have rebuilt their Cosworth lsd unit bought the fluid at Ford. I've also talked to CTS about buying fluid, but since they have spent money on developing the fluid, the wouldn't sell it.

 

Is the ball bearing still in place in the case ?

 

I haven't taken my box apart yet.

 

ive rebuilt my box i took my lsd to a place in bromsgrove called bara motorsport had it rebuilt and modified,he changed the fulid to a different viscousity and that worked wonders it tighted it to 120nm,very tight diff ill get the number up for you

 

I have already sent it to him yesterday matey

Got to bear in mind he's from abroad and posting diffs to the UK will be expensive

 

How much did you pay? All they did to tighten it was to change the fluid?

 

Talked to DOME, and nobody will sell the fluid seperatly.

 

... and your next option is ?

 

it had the fluid changed and was rebuilt use new parts,the cost was 300.00 quid

 

had the same problem,no one will sell it

 

I will have to search further for this fluid. Everthing I do on the car is DIY.
