And even then, if you keep your getrag tranny, you should still be able to use it. The only reason you'd need to use a different shaft would be if you switched to a ZF tranny(comes stock on 328's and M3's) which is about an inch and a half longer than the getrag and has a larger bolt pattern on the output flange and flex disc than the getrag. If you use a ZF tranny, you'll need to use a manual M3 or 328 front section with your stock ti rear section. As for the diff, as long as the diff you're using has a 4 bolt input flange, you'll be fine with your ti shaft. If it's a 6 bolt, you'll either need to swap the input flange or find a 6 bolt rear section off of a Z3 or Mcoupe. Hope that helps, best of luck! | | | 04-24-2011, 02:40 AM | #3 | Senior Member Join Date: Nov 2009 Location: Maryland Posts: 265 | Quote: Originally Posted by cooljess76 You should be able to use your ti shaft until you decide to do the engine swap.

I was trying to put my 3.73 in this weekend but its not happening. As jesse said, the stock driveshaft should be fine, you should only need z3/e30 halfshafts and abs shims. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM | | | 05-24-2011, 02:37 PM | #5 | Senior Member Join Date: Mar 2006 Location: Golden, CO Posts: 283 | Plus 1. Use the stock drive shaft, ABS shims (I just found some washers and cut notches in them to fit), and new halfshaft. __________________ e46 325 brake upgrade, Dinan engine chip, UUC SS brake lines, UCC rotors, m68 17in wheels, Conti extreme contacts, Billstein sport shocks, H&R springs, M3 shock mounts, B&B triflow exhaust, K&N cone filter, Magnecor 8.5 wires, Meyle control arms with caster , Hawk ceramic pads, Understeer M3 SSK, UUC SS clutch line, 320 trans mounts. | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
