What car did a 3:91 dif come out of

[bpmack16]

I have one on my e30 and is the best setup. I am looking for another one?

US cars never go the 3.91 .

Was available option for the rest of the world though on the early cars .

Sorry to burst your bubble but I am pretty sure you're wrong on that one.

[Teaguer]

Really ? What part ?

Tell me otherwise , I'm always willing to learn .

325ix 5-speed

uses a VC clutch though, not sure how well that works on a RWD car.

[MR 325]

I could have sworn some auto B25 cars had a 3.91 aswell.

[DEV0 E30]

Some early 318s did.

[reelizmpro]

No 325's in the US got 3.91's (not sure about iX). I do believe the 3.91's came on some 318i's but in the smaller casing.

IX stickshift has it in large case.

Early 318s may have had small case ones.

Later E24 autos had it in large case. You'd have to swap the rear cover and possibly flanges to make it work though.

[Rigmaster]

Here we go again.

Early 325e's had 2.79's, later 325/325e's had 2.93's, most 325i/is' had 3.73's except for the later 325i/is automatics which got 4.10's.

325iX did have the viscous 3.91 in all '88 cars and 5 speed cars after '88, they got the viscous 4.10 in the auto tranny cars from '88-up.

That's about it for the 6 cyl E30's sold in USA.

i got a 3.91lsd sitting in my garage. i bought it from Mot on here. it came off his 84? 318.

[SA E30]

Over here in SA we only got them on our 325iS Evo 2 , in the UK I know they got them on the M-Tech 2 325i Sports.

All our 325i came out with 3.64:1 and our 323i came out with a 3.64:1 LSD
