which diff?

[mark320i]

currently got a 2.5 running off a 2.0ltr box, can i also run a 2litre diff aswell or will i just fcuk it?

[mark320i]

anyone?

[Simon]

320i will have a small case diff, ideally uprate to a large case, with a lower ratio, car will rev high on the 320i diff.

I've got a 325i converted touring, still running the 320i box, and a 3.64 LSD, and it's a great set up.

[mark320i]

will it be driveable?

[Simon]

Yes, but only temporary, I wouldn't leave the 320i diff on permanent.

[mark320i]

yeah dont want it on there long maybe only a couple of weeks? should i drive it carefully in fear of totally destroying it or will i get away with giving it a bit?

[stevetigger]

Drive carefully!

[mark320i]

lol! is there any point driving it with the diff on or should i wait to upgrade?

[stevetigger]

Should be OK for a bit, Andy325i drove his car that had a 320 diff on, but a M52B28 engine

[mark320i]

just dont wana be driving down the road and end up ripping the thing off lol!

[stevetigger]

Not if you drive it sensible, you can drive fast but not hard!

[mark320i]

how do you define fast but not hard steve?

[stevetigger]

For example, once you are in gear you can put your foot down and drive fast, but don't change gear rapid and thrash it off the lights!

[mark320i]

ha ha got ya mate! that should be fine.

[stevetigger]

Cool!!

Just drive nice and steady but quickly if you need!

hi i've mashed my diff up on my 320i se but my mate has a 325i diff that i can have (coz he done most the damage) but he aint sure if its lsd how do you tell? are all 325i's lsd and would it be ok to just put the diff straight onto my 320i without changing the box please help coz my baby's disabled!!!!

[Jhonno]

turn input.. both outputs will turn the same way if its an lsd

not all 325i's had lsd's

it'll say on the tag the ratio, if not count how many input turns are req to turn output once..

[gasboyjay]

cheers mate. could i still put it on my 320i? either way?
