The Random E46/ZHP Question Thread

[cornercarver]

LSD is absolutely one of the best upgrades - especially if you shorten the ratio to something like a 3.46. and you're fortunate to have diffsonline right next door!

Holy crap! I didn't realize they're in Wilmington. Maybe I can talk them into giving me one for R&D.

The Mfactory stuff is definitely a lot less expensive though.

Be careful with 3.46’s. Aren’t the input flanges different? 4 bolt vs 6 bolt or something? This is something I paid a lot of attention to since I am doing a 6 speed swap. I read a few times that the 6 speed driveshaft won’t bolt right up. An auto 330’s 3.38 a different story. From my inspection at junk yards, it seems all non 330’s got one design and all 330’s got another. Some one prove me wrong?

yep, the input and output flanges are different. not hard to swap over from your stock diff. maybe 20min of work.

Fair enough. Just scary to me because there is no rated torque for that bolt. I will most likely get a 3.38 for the easy and the difference is like 2.3%. Just with my luck I wouldn’t get the input bolt tight enough. Murphy’s law

Spenser, Shawn's got a 3.38 that I believe he quite likes.

Did the Z4 come in 3.38? Kinda want that sweet sweet finned bling, yo.

Yep. I love 3-4 gear. And 6 is awesome on the highway—not much Need to downshift at all. Great mod. Not sure I’d go past 3:46 but never driven a 3:64. It may not make that much difference at highway speed.

[QUOTE=nextelbuddy;558559]I use the 7 liter one I got on amazon warehouse deals. for $50ish dollars

takes about 5 min to pull all the oil out.

In the reviews for that pump, a fair number of reviewers report it failing and pumping oil out of the handle after 1-2 uses. Have you run into any problems?

I’ve already gone through 2 MityVacs. I’m not too impressed. They leak after a short time and the way the rubber plug is designed, makes it difficult to drain the oil into another container to take to the auto parts store for recycling. They are a waste of money.

The EWK unit I bought is much better. Better design and user interface. Easier to use and dispose of the oil.
