Saw this on Ebay. seems to mount the same as the 318ti. I did some research on REALOEM.com. The diff seems to be as he states 3.46:1. The problem is when I search under 2001 Z3 M, they only used a 3.15:1 diff. Either way the mounting seems the same, but I can't figure out if this is really from a 2001 Z3 M. I would love to put that in my 98 318ti. Did all Z3 coupes/roadsters come with a LSD? If this diff bolts right on, do the half shafts still need some mods, as in an E30 diff swap? http://cgi.ebay.com/ebaymotors/ws/eB...category=33731 __________________ 1998 (July) 318ti, 5-spd OEM Armrest Blaupunkt Heidelberg CD50 CD Player/Compact Drive MP3 Player Diamond Audio 5.25" rear speakers Navman ICN 530 GPS BMWALARM.COM (with comfort settings) after market alarm system Magnecor 8.5mm wires M-Z3 Shifter/Momo Knob Burlwood Dashboard Stromung Exhaust X-brace Racing Dynamics Front Strut Bar Carbonio C.A.I. 17" Rial Rims Vader Seats/Heated/Lumbar Support M-tech Steering Wheel/Front Sway Bar/Front & Rear Bumper Depos/w 6500K Angel Eyes/6000K HIDs Clear Corners M3 Mirrors UUC Light Weight Flywheel/M5 Clutch/M3 Clutch Slave E28 3.46 LSD/Mcoupe Cover/E30 Flanges & Halfshafts UUC S.S.

I believe later M models came with a torsen diff which I believe is better than a clutch pack LSD. Look in the ti notebook section. Their is a writeup on different types of diffs. __________________ ...steven BMW CCA #146825 1996 BMW 328ti 2003 MINI Cooper S 2016 M235i www.bmwcca.org | | | 01-18-2005, 08:16 PM | #3 | Senior Member Join Date: Dec 2004 Location: Colyumbia S.C.

I would like to get a consensus. Do you think that the year and model the auction states is correct? I am trying to confirm it, but so far I can't.

Posts: 101 | Must change shafts. the diff is wider (stronger) so you must use the shorter, fatter, stronger shafts. you will also need to change the flanges to match the axel. | | | 01-19-2005, 02:59 PM | #10 | Senior Member Join Date: Sep 2004 Location: Manassas, VA Posts: 4,129 | I read the procedure for swapping an E30 6 cylinder diff to a ti. Since this diff is the larger body diff like the diff I am interested in, the concerns should be the same. The procedure said I would need to swap the flanges but not the half shafts. Why would i need to swap the half shafts? I have a low mileage car, and would like to keep as many parts from my car as possible in the swap.

Any 2001+ 2.5-3.0 liter Z3 half shafts should work. I am not sure about the ///M versions or the ones prior to 2001. 1.9l Z3s use the same differential and halfshafts as the ti.

You are correct, M coupes/roadsters never had 3.46 diffs. I did extensive searching through REALOEM.com. The Z3 1.9ltr did have a 3.46 diff, but it was different model than the one up for sale. The diff I am interested in checks out to be from a Z3 3.0i 1999-2002 models. The part # on the diff crosses exactly to the REALOEM part # for those years. That makes sense to me for this reason. If you look at the diff rear cover on the one for sale, it DOES NOT have the finned cover that comes on the M/coupe. That "M" that is stamped on the rear (picture) must not mean M coupe/roadster. Then everything else checks out. Any comments? I have the sellers phone #, and he said to call with any questions.
