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

Looks like a standard 4.1 WRX diff to me from those pics The 9.37 is the ratio - Divide 37 by 9 you get 4.1.

Good luck David API
