Help With My Diff

[Guest CRAIG D]

Hi,

I found an old diff from my 1995 sti, i wasnt to sure if it was knackered so i stripped it down and everything seems to be fine.

There was a couple of questions i need to ask

1, from the pic would you say it was a standard diff or an uprated?? Reason i ask is that am sure when i was getting a new gearbox the last time round am sure the guy said it was an uprated diff??

Only words on it are japan NGK ???? and number are 37.9 BP 4 621 Does that suggest anything??

Here is a pic of the diff

2nd thing is i wanted to know what gearbox would suit this ?? agin only letters etc on it are

TR 704 B KN51 Again any ideas??

Hope sum1 can heplp

It's a 4.11 ratio diff, looks like a standard Viscous LSD from what I can see. A better picture showing in through that circular hole would confirm this.

An box with a 4.11 front diff and 1:1 drops will do.

Thanks John,

Just had a look at that SPDA transmission chart thingy majig and it looks like from what i can see that the original rear diff from the ra is slighly better so i think il get the original diff.

Thnls for that m8
