who has what diff?

[JPStrniste]

Hey Guys,

Interested in seeing what everyone is running for a rear diff in their swapped cars and what they think of them, what would you suggest, ect.

just trying to see what's fun to drive and how the gas mileage is. what the highway vs. country road driving is like.

obviously it matters on the tranny you're using. So, let us know:


I'm (will be) running: 3.73lsd with e36 getrag

[MR 325]

S50 with E30 260 trans and a 3.73 LSD. I think it's perfect.

[1990m3]

s50 with ZF e36 m3 trans and a 3.46 LSD, I also think this is perfect!

[Erik j]

I ran a e46 trans/e30 m20 with a 373 diff and it was really bad, 70 mph was at 5500 rpm.

[smonkbmw]

getrag 260 with a open 3.7 on my cammed m52 swap. 60 was 2600ish. got 335 miles to the tank on the highway.

s52 / e36 trans I started with a 3:25 it's a perfect gear for a daily driver. I swapped to a 3:46 and holy sh@t is it fun but highway's get old .

s50 with ZF e36 m3 trans and a 3.46 LSD, I also think this is perfect!

This is my favorite ratio! It is a blast with the euro S50 and the rev happy nature of the engine.

G260 with S4.10. Going to be fun.

m20b25 w/260 & 3.73lsd

Almost perfect other than not near enough HP !! LOL


EDIT -- damn I now see this is in the 24v thread ....

[kolunda]

S50 w e36 ZF and 3.25, It's perfect for me.

S50 with Getrag 260 and 4:10 LSD

I left the 4:10 in that I was running with the M20. It needs the 3:73 LSD that I have sitting in my garage that I'm too lazy to change.

Maybe this post will motivate me.

What don't you like about the G260/4.10 combo?

[02stu]

I am running a 4.10, which sucks on the highway. But if you do the math a 4.10 should come out to exactly the same gear advantage over a 3.73 as the s50 horsepower advantage over an m50.

M30b35, Getrag 280 (slightly taller than 260) and 3.46 diff.

Straight holiness

[mbonder]

m50+ e36 trans+3.25lsd

I've heard its the best for DD, I'll let you know when the swap is done!
