Fs: 3.73 lsd

-366kms
-Locks good
-no noises
-Changed the oil @ the beginning of this year

$250 Firm but may entertain resonable offers. low offers or messages asking "whats the best you can do" will be ignored...Give me an offer and its either yes or no.

The diff is still on the car so give me 1 -2 days to remove it.

Post or PM me.

You have an m42, so your stock diff is 4.10 small case. This diff is going the wrong way. It's elaborate BTW.

3.73 would help bring down your rpm slightly, but not much. im not to fond of 318's but i dont see why it wouldnt work. sorry for the limited help man, lol

So wait, you want your 4 cylinder convertible to be even slower? Drive a civic if you are worried about gas mileage.

i dont know but for some reason i cant get more than 250km per/tank,and i think thats too much for a 318. I want to get more power but fix the gas mileage as well.

Whats my options for diffs?I wanted to change to an LSD.

Something is wrong with your engine, changing diffs will not solve the problem, only mask it partially. Figure out what the hell is wrong with your car before you start to upgrade unrelated items.

Something is WAY off here!!! Either the engine not running right, or you driving the hell out of it (but even then it shouldnt be that high)...Even in the worst times (winter, running cold most of the time, and hard driving) i still get 500+ Km from from my M42 (in E36 thats about same as your E30 caby)...

Its a direct bolt-on, and will help with your gas mileage..(along with a tune up to do something about that 250km/tank) and you will be superb AND have LSD!

What size are your tires? Where are you getting the 250kms/tank number?
Sure you dont have a higher ratio like 4.45?
100km/hr in a 5spd with 4.45 diff on 24"dia tires would be around 3871.5 rpm. smaller tires would be higher rpm.
a tune up good tires/inflation and a smaller ratio diff will get you better mileage

250 km per tank is pretty brutal. You should be able to get 400 without trying, upwards of 600 highway if you're being frugal. I average around 8 L/100 KM in mixed commuting in my M42 E30 318i, which would work out to around 625 KM per tank if I refilled near the end of the tank.

For reference, I was averaging around 8.8 L/100 KM when I was running the stock 4.1 open diff. I recently swapped to a 3.25 small case LSD and my mileage dropped into the high 7s, low 8s. Highway revs are just a hair over 2,000 rpm. It's slow, but whatever -- everything's a tradeoff.
