Thanks dude, this is actually something I'm doing for my brother. He's always saying, that e30 owners are too cheap and I'm trying to change his mind set.

Unfortunately the sales is proving him to be right........

Starting a 5 speed swap on my car soon.
Any ideas on what diff I should get?

[Bimmerman325i]

Which trans?

Zf310/320 ->> 3.15/3.23

G260 -> 3.73

G260
Cool Thanks.

Dumb Question...Differents between 3.73 vs 4.10?

[Vivek]

The ratios. On an m20 a 4.10 will be super short. You'll accelerate like a rocket but shift 12 times to get to 60, and by 61 you're at the rev limiter.

Cool Thanks.

Dumb Question...Differents between 3.73 vs 4.10?

vivek that was a terrible explanation.

g260 with 3.73 with revlimit to 7000rpm

1st maxes out at 34.9mph
2nd maxes out at 60.8mph
3rd maxes out at 95.6mph
4th maxes out at 133mph
5th maxes out at 165mph

g260 with 4.10 with 7000rpm

1st maxes out at 31.8mph
2nd maxes out at 55.3mph
3rd maxes out at 87mph
4th maxes out at 121.8mph
5th maxes out at 150.3mph

as you can see, with the 4.10 diff, you will accelerate faster because you go through the gears faster. But the top speed is slower than the 3.73diff top speed.

the 4.10 diff will also have the engine revving a little high at freeway speeds.

very good explanation Patrick,
thanks for dropping some knowledge!

just ordered the last of my parts for the e30.
all thats left is a new radiator.

thinking about getting this CXracing one that another member was posting about, seems nice!

I had a 4.10+G260 in my vert for a year. it annoying to go through first gear before passing the crosswalk on your side. also if you autoX is usually the wrong gearing for the courses, getting to 60mph means you have to grab 3rd and then try to for it nearly immediately back into 2nd and no G260 likes that change.
to sum up
get the 4.10 if you like to drift or drag
get the 3.73 for DD/road courses.

pants you have an early model cooling system, make sure you get the correct radiator. the one in the pic is for late models.

:/ i was feeling like the amazon page was wrong.....
lame.

as far as i know no one makes a nice ETA rad.
but what exactly is the difference in the two that would make it incompatible with a b27 head?

yes and no, on your budget, no. on someone willing to waste a ton of cash, yes.
they are the same size, what it different is the input side is at the top on a b25 and its at the bottom on the b27. and likewise revers on the output side.

[Pantless Spency]

and i take it you can't make your own coolant hose that would work?
probably because of water flow reasons correct?
