nice, shawn! no swapping of input/output flanges. i had to swap mine, it wasn't hard, but i did have a bit of a 'moment' when i realized i did not have a 30mm socket to remove the input shaft flange nut... fortunately the shop doing my exhaust work let me borrow one. :)Quote:

THANK you so much, this site is a gold mine for information
Shawn, are you going to do the subframe mount reinforcement?
I need to find the time and a family member to assist me... Had not planned to do subframe.

You're probably better off buying one directly from them if you really want one.

If you don't mind waiting, then the wait for a used one could be worth it though, depending on price. Good luck finding one; hopefully it won't be too long a wait.
well, the koch tools subframe mount tool should allow you to do the bushings on the car; you basically would do this:Quote:

5. disconnect driveshaft from rear diff
6. support rear diff/subframe with jack
7. unbolt subframe from car
8. lower subframe down so that it clears the front studs (the two front subframe bolts are studs, and like 4" long!)
9. use koch tools subframe mount tool to remove old rubber mounts
10. install black AKG subframe mounts (best design that i could find - they fit totally flat against the floor, helping to distribute the load over a greater surface area)
11. raise subframe assembly and bolt back up!
12. reassemble
now, since you're swapping you diff out, you would remove it at step 5. with the diff out of the subframe, you might want to build a crude 'spacer' out of 2x4 scraps to put in place of the diff, for raising/lowering the subframe.
aaaand... you might as well replace your diff mounts at the same time because it's never going to be easier! :) the koch tool makes it a breeze.

after looking at the three different setups on ESS' site, i would hands-down go for the VT1 kit. first off - it's the most affordable, by about 20%; it's the least-invasive as far as installation goes; it makes nearly the same power as the stage 1 twin-screw kit.Quote:

Yikes. I plan to do the diff bushing but doubt I'll get to the subframe.Quote:

if you've got the diff out already, it's not that much more work... effectively lowing the subframe down and that's not much extra work. :) plus you can have peace of mind about protecting your rear floor, because undoubtedly you are going to be doing some burnouts with the LSD. ;)Quote:

I would certainly go with a LSD first. There are many reasons, but the main being that it's the best bang for buck. You'll be able to properly power out of corners, and the fun factor goes WAY up. Secondly, a supercharger would be that much more fun with a proper diff, and two tire fire. You have a ton of options for diffs.Quote:

After a bad experience with OS Giken (see here: http://www.zhpmafia.com/forums/showt...iness-with-OSG), I try to refrain from using parts manufactured in that part of the world.
Ultimately, I purchased a LSD from Diffsonline, http://diffsonline.com. They've been building differentials for the BMW market specifically, and for over 15 years I believe. They are manufactured and assembled here in the USA, and have an unbeatable reputation. My unit has been perfect for well over a year, and drove like a brand new BMW differential from the moment I dropped it in the car. Should anything go south, their warranty is the best in the market.
In reading the warranty info that came with my MFactory LSD it says it's only granted if they or an approved shop install it--not a DIYer...

LOL, OSG doesn't warranty anything, regardless of who installs. They essentially tell their customers to F*** off.Quote:

For example...?Quote:

This. If you do luck out and eventually find one used, it will probably run you about $4500 for a used TS2. Then you need to pay for the tune on top of that, another like $800 or so.Quote:
