Subaru Diffs

[DaveNotSoSideways]

Ok then girls.

 

Looking for a Subaru Diff with 3.8 or 3.6 ratio. Has to be LSD  ;D

 

Anyone know what model of car has what diff?

 

I think I will stick the scooby rather than ford as them ford ones they aren't cheap by the time you add in a LSD and custom-made odd length driveshafts etc.

 

The car needs a LSD so badly, its next to useless trying to apply power on dry road when its this cold

Excellent choice, sir, step this way...

 

My GT6 has a 3.7LSD diff, and I'm looking forward to the day when it moves under its own power and I can see how it performs. I bought it off the shelf from a wrecker, so don't know what model it came from. A spot of Googling suggests an '87 to '89 RX Manual, but they must be a rare beast these days, and they may have come in other models as well. Mine's an 'R160' type, meaning a 160mm crown wheel. Unless you're using one of the cast alloy backplates there's no reason not to look at R180s and R200s as well, and they may come in a 3.7 LSD ratio. Most Hitachi diffs have higher ratios, eg 4.11 or 4.44:1 to suit high-revving modern engines.

 

My plan is to use Nick Jones' CV conversion, and make (ie pay someone to make) adapters between Nick's inner CV joints and the splined output stubs. An alternative would be to make (ie pay someone a lot to make) custom halfshafts. I think it's also possible to fit Datsun UJ'n'spline halfshafts, but they're bulkier and heavier, and there'd still be fabricating to do at the wheel hub end.

 

Before you forswear Ford altogether though, you could have equal length halfshafts if you mounted the diff slightly off-centre. Being alloy, they're lighter than the Subaru/Datsun/Hitachi family. Then there're heavier alternatives like Jag, P6 Rover or the 3.08:1 Holden diff in my V8.

Nick - Not really sure thats posible due to the chassis rails/propshaft and position of the pinion/prop flange - looked into that when setting up mine

 

How about Freelander - Westfields use them as an alternative to Ford?? Not sure what range of ratio's there are but seem to turn up in local breakers more so than Sierra's or Scooby Doo's

A bit of searching found this:

"The Freelander rear Diffs are all 3.214:1"

Older Celica diffs might be worth a look too, nice and compact, once again there's less demand.

This sort of thing? Pity its in the US... is the price about normal?

 

From a brief look about the R180 is more pricey .... I will check things out over here as there heaps of cars on the 'tuning scene' that use this diff. Not sure what the going rate is in the UK

From my limited searching, alot of the import vehicles are fitted with 4.11's, I think 2002+ UK cars tend to be fitted with 3.54's.

Not all fitted with LSD, if fitting a viscous diff you will also need the matching cv joints as one of them has a step with a second spline.

KDT now has a casting for the rear of the diff that will allow it to fit the original rear chassis mounting points, still a bit more work to do but its close.

Go for a 2nd hand diff should be alot cheaper then recon unit plus lots ratios

Hi Barry

I to am fitting a sub LSD

 

I found it to be the best choice for lots of reasons

 

manly, the LSD works on oil, and with changing oil viscositys, you can change the LSD chariteristic (spelling)

 

It has less wearing parts, its very small etc etc etc

 

I Thing I know off one, BUT it may be a 4;11

 

Mine is a 3.8 odd ish, cant remember

 

any way, there is a guy on this site, he has a spitfire (white) with a fiat twin cam,

 

think I have his number

 

I will contact him and see if hes selling it,

 

Just PM me if you still need it and I will make the call

Don't worry Urge, "LSD" is the correct spelling ;D ;D ;D :

 

 

 

Like Julie Brown sings, "I can't spell VW but I drive a Porsche..."

Think the diff might be next winter, immediate priority is to stop the wheels coming off.

 

I'm going to need to tackle this job carefully and in 3 stages to keep my car working this year.

 

Brought some stuff to move things forward. Be some progress soon Going to gather all the elements in the equation first. I can do the diff last.

 

Aiming for something like this Westfield setup, simple maybe using the complete MGF upright/brakes provided they IF fit under 14" wheels. (Nick can have his hub rings back)

 

Want/need wider rear rims, maybe 6.5"-7", so things need to factored in and considered.

 

Need to pickup a few more parts and stir.
