OBD1 s52+3.46 lsd+ZF 320 = OMFG!

[e30polak]

Finally, after waiting over a year to grab a 3.46 lsd, I got one!!! After installing it about 2 hours ago, my life has officially changed for the better! The gearing is simply perfect!!! :bow:

I have been running the 3.25 for the past 2 years and have always liked the gearing, but I always wanted to shorten up 3rd and 4th. Well now I have the best of both worlds; fairly long legs, with a little extra oomph in each gear! :twisted:

Easily one of the best mods I've done to my car! :woowoo:

damn, i wonder what gearing i should be running then.. is it worth it? i have the 97 zf tranny with the s52 and 3.25 lsd now.. 3.46 sounds amazing.

Yes! Especially since you have cams!!!

The 3.46 is one of my favorites mods I have ever done to my car. If you have a zf tranny you have to get the 3.46.

love my 3.46,

See my track footage thread to see how it does on track!

[guibo09]

what are the gear ratios for the ZF 320?

[StreuB1]

I currently have a 3.73 in my car....cant wait to see what its like once I swap...........

cant wait for the good...and the bad. GF lives 40 miles away on the highway. :-\

we'll see how bad it is.

3.73, and a ZF or a Getrag?

I think you'll find yourself saying, "not now, I have a headache".

Lol. Hot damn. Kudos to you! I wanna see/feel. We need to really do a side by side roll to show examples of a s52 with a 2.93lsd and a s52 with a 3.46lsd. =P

Wanna buy my 3.25, I bet you you'll love the gears compared to 2.93! :D

You'll be cranking at least 4k at 70 if you use a zf with 3.73 gears. Those are way too aggressive for a DD. Jesse runs them on his m52, but there is way too much shifting involved. :crazy:

[loonibab325i]

man first gear and most of second gear is pretty much pointless with the 3.25 even with 235 rt-615 tires. how hard is it to get traction with the 3.46? And i know gearing doesn't "give you power" but does it speed up acceleration? what is the gears strong points?

Anyway, glad you found a bad ass drivetrain setup.

Can't be as good as my 2.93


But I second the traction question. I can't hook 1st even if I roll the throttle in, and that's with 245/45/16 Z212's. They're probably heat cycled out, though :D

The shifting isn't all that bad, it's the tach out that sucks the most.
