I have a 96 auto, so would want to swap for an LSD from an auto; an e30 with a small case sounding like the easiest. Not buying this one, but this is essentially what I'm looking for?: http://www.ebay.com/itm/BMW-e30-e24-...item4cfdc1460d Thanks. | | | 02-01-2012, 01:49 AM | #93 | Senior Member Join Date: Jul 2011 Location: TX Posts: 107 | Quote: Originally Posted by mreroc Read through this thread and just want to make sure I am reading right...good chance I am not as still learning under the car.

A small case diff would come from a 4 cylinder car. | | | 02-01-2012, 01:51 AM | #94 | Senior Member Join Date: Aug 2011 Location: Phx Posts: 196 | Right, right. Thanks for that heads up. Figured I miss something even though the info was right there. | | | 02-01-2012, 12:12 PM | #95 | Member Join Date: Dec 2011 Location: TBILISI Posts: 70 | anyone ever tried the polyurethane diff bush? i can make solid rubber one, or urethane or whatever. what are pros and cons? | | | 02-01-2012, 12:40 PM | #96 | Senior Member Join Date: Apr 2007 Location: Elizabeth City, NC Posts: 3,877 | Whatever material you use for the diff bushing should also be use in the subframe bushings. Stiff diff bushing with sloppy subframe bushings would probably lead to the diff mount welds tearing. Randy Forbes does the diff mount repair when it tears on Z3s and he recommends urethane subframe bushings with a stock M coupe diff bushing. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM | | | 02-01-2012, 01:05 PM | #97 | Senior Member Join Date: Apr 2005 Location: Henrico, VA USA Posts: 231 | Subframe and diff bushings?

My question is this, I got one of the Motorsport finned covers I am planning to use on my 188 diff as soon as I finish it and I bought it used for a very good price with a like new urethane bushing in it already. I was told it was an AKG bushing and it is supposed to be an 80A durometer urethane and I believe it is a purple color which is supposed to be a street compound. I am planning on doing the subframe and swing arm bushings as well and wonder which might be best anyway but am thinking the PowerFlex purple ones, would the be compatable do you think with the diff bushing I have or should I replace that as well? I wonder if I should use urethane at all and just use stock rubber all around? Is there any better than other stock parts that can be used? Is good urethane better? I like a taught car and don't mind a bit firmer feel as I am running TC Kline D/A's front and rear with 400lb front and 500lb rear springs so firm but not hard so I like compliant and not stiff. Any suggestions as it looks like I may start this project sooner than later and one other thing is I am likely going to have to tackle most of the work alone so ease is a factor.

I was somehow planning to swap my engine with M52b28 and I was going to mate it with my current tranny (Getrag), will that be alright? and the propeller shaft should be good? also planning to do 2.93 LSD as I drive a lot on the highway and mainly I use the car as a daily drive than autocrossing! Any Advices for that? | | | 01-02-2013, 06:30 AM | #105 | Member Join Date: Oct 2009 Location: OR, USA Posts: 61 | I believe it "should". I did an S50B30 swap with the same Diff as you (and e30 6cyl. axle half shafts) But i did take my drive shaft in and have it shortend an inch as well, he also balanced it. Still good a few years later. __________________ =F.N.B.= /!\CAUTION/!\ Low Flying Engines | | | | | 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 | | | |
