which trans is better?

right now i have a 98 m3 5 speed mated to my m50 in my e30. i see alot of people using the e36 325 5 speed, and am wondering which is better. i know the m3 is a liitle heavier and also beefier but which has a better ratio for cruising on the highway? will my m3 240mm clutch fit in the 325 trans? i have a 325 trans laying around and have to pull the engine to drop in another chassis so it will be convenient to change the trans while its out. thanks.

I assume that the OBD II M3's 96+ use a diff ratio of 3.23.
What type of driving do you normally do? Are you a drag racing, auto-xer, tracker, regular cruiser?

Do you find that your revs are too high at the speeds that you cruise at on the highway?

i travel a lot on the highway, do a lil drag, and am looking to get into autocross soon. i just want a quiet 5th with a good 1st gear takeoff.

The E36 325 gearbox (Getrag 250) has the same (minimal difference) ratios as the E36 M3 (ZF 310/320) gearbox. The M3 240mm clutch/plate/fly WILL fit in the G250 gearbox.

Go ahead and use the 325 gearbox you have, as it is lighter than the M3 'box and will work fine with a 240mm clutch.
