ray007 Posted April 14, 2011 Share Posted April 14, 2011 Hi all I know someone selling an LSD for mkiv supra without the casing He says it's a 12 bolt LSD as opposed to 10 bolt. Which casing would I need for this? Quote Link to comment Share on other sites More sharing options...
Homer Posted April 14, 2011 Share Posted April 14, 2011 B03B = large casing A03B = Small casing Quote Link to comment Share on other sites More sharing options...
ray007 Posted April 14, 2011 Author Share Posted April 14, 2011 B03B = large casing A03B = Small casing Thanks darryl, it's the b03b. So the larger casing are from pre-facelift cars I guess? Quote Link to comment Share on other sites More sharing options...
ray007 Posted April 17, 2011 Author Share Posted April 17, 2011 Is the A03B the one with the 10 bolt LSD's? i know someone else who has also a 10bolt lsd for sale, would that fit in an auto tt non lsd casing? and can i as the oil cooler to it?

Homer Posted April 17, 2011 Share Posted April 17, 2011 I don't think A03B is possible, Nic would be best to confirm. There's two "actual" diffs I beleive, the one for the small casing, one for the larger. The "big" diff can't fit into the small casing.

ray007 Posted April 17, 2011 Author Share Posted April 17, 2011 Ok, many thanks buddy Now I've got to make my mind up which one I should get As I said I've seen a BO3B (12 bolt for larger casing) and the A03B (10 bolt for smaller casing) If I could you my current non LSD auto Tt diff that would be nice... Maybe not possible Also got an r154 going in a few months time... I don't think A03B is possible, Nic would be best to confirm. There's two "actual" diffs I beleive, the one for the small casing, one for the larger. The "big" diff can't fit into the small casing.

Chris Wilson Posted April 18, 2011 Share Posted April 18, 2011 The large casing axle units are of course stronger, as they have a bigger crown wheel and pinion. You need drive shafts to match. Quote Link to comment Share on other sites More sharing options...
