[gregslow318i]

2.79 lsd ftw

maybe if you're supercharged or turbo'd...:roll:

i have the 3.25 LSD in mine, but with the amount of power in the car i wish i had the 2.93.

[e30polak]

No way! I want torquier gears! 3.46 = perfection! :twisted:

[MDryVur]

that's pretty short for a zf trans

ill be using the e36 m3 tranny .... that should be better right? right now the diff is in my vert. great grip on the road...


off topic but does anyone know some one that would want an 97' m3..

[FredK]

The E36 M3 has a ZF transmission.

[BeirBrennerE30]

wow you guys dont like having torque...

[MDryVur]

dude i would love TORQUE..... we wouldn't want to be called torque less wonder now would we.;-)

[FredK]

A 2.93 or 3.25 with an S52 will not lack torque.

If you have a 6 speed transmission like BeirBrennerE30, then a higher ratio diff might be in the cards, but I would prefer not turning almost 4500 rpm at 80 mph with a 3.91 and a 1:1 5th.

sorry that diff is for me ;)

even without overdrive you could still do 3.64. i even bet 3.73 isnt bad. anything in the 2's is way to high.... your top speed would be over 200mph and you dont have the hp for it.

[loonibab325i]

WOW, i can't imagine what it would be like to have a 3.91. Brenner, do you have any acceleration videos? Also, what's your top speed on that setup?

I'm running a 3.25 LSD with my obd1 s52 e30, shricks, and bolt ons. It is definitely torquey enough. http://www.youtube.com/watch?v=coN7uwQqAws (e36 b-caps & tires)..

Personally, for daily and occasional track use i wouldn't go over 3.46, a 3.73 MAX.

Although, i was running a 4.10 diff for a while, that was just a JOKE! the diff locked up after 5 minutes of driving the thing lol.. that's what i expected with a small case 4.10 though.. FAIL

[BeirBrennerE30]

i have vids but they are HUUUGE... im talkin gigs... and they seriously would need editing.

My top speed is over 170if i recall correctly. This is more than fast enough for an e30 that sees the street. Aero probably wont let me get that high anyway

dude thats freakin awsome... how much did the tranny cost you... i might go this direction... do you still use the same drive shaft or was this a different set up...also did the tranny bolt up to the motor ok or was that custom as well.

[windsor318is]

oh wait, you probably aren't running the M3 tranny are you Windsor?

no no i am running the m3 tranny i was already at 300rpm at 60mph, i guess if i broght it to redline it would hit 100!! ill have an undate on my thread about rebuilding the 2.93 shortly, in case people are buying new ones after destroying bearings.
