I have a 2wd saff cossie which is fitted with toyota supra diff.
The previous owner knew very little about the cars exact spec so was wondering how can I tell exactly which model supra diff I have fitted and once so I'd ideally like to know what ratio it is...

Any advise much appreciated

Cheers Paul

 

3.7 is the most popular one so must likely be that one,
I ve a 3.7 in my car,
there are 3.9s about too but not as easy come by

 

Bara rebuilt mine for me and he is able to reset all all the ramp angles etc to suit the weight of the cossie.

 

Interesting....
Do you know if they are able to change the crown wheel and pinion ratios?

Cheers Paul

Good question, just google bara and give him a buzz, super nice bloke

 

Will do buddy, anyone in particular I would need to speak too?

Cheers Paul

 

Yes, his name is Bara lol.

I thight the company was bara too, his name is bara Singh....top bloke!

 

Ha ha ok cool, will ring em, thanks

Cheers Paul

 

Spoke to bara the other day, top bloke and gave me some sound advise, will be sending the diff away to him soon for a full rebuild.

Cheers Paul

 

Cool, glad he could help, I spent a bit of time speaking to him last week too.

 

Well i opened mine up and was sold as a 3.72 but turns out to be a 3.9 due to having 43 teeth on the crown wheel - should be interesting

 

Yeah he seems like a proper sound guy.
You'll have to let us know if you can notice any difference Brammer...

Cheers Paul

 

Nearlly got stung on bay sold a 4.10 for a 3.9 luckily a stopped the sale after finding out the diff was wrong and got a refund bara is a top bloke hes now supplying me with a 3.9 will be fully rebuilt bram think hes got 3.7.s aswell

 

Nothing to compare it too, sold my other diff which was a 3.72 - i'd imagine this will suit my car better
