Diff identification

Hi All
Does anybody recognise this diff? I'm looking for the diff type and the ratio if possible. Thanks http://i366.photobucket.com/albums/o...b/DSCF1435.jpg Attachment 50137 |
Copied from another thread, this info was posted by David at API....:)
The UK Subaru dealers have a bulletin that I have a copy of, which shows a code number on the rear diff. There are various options for R160: VA1 RBF - XF is a 3.9 for a 1600 manual tm. VA1 REF - XJ is a 4.111 on an auto non turbo these two are stickers T1 is a 3.9 on a 2 litre Manual non turbo BJ is a 3.545 on a UK / Euro turbo car these three are letter stamped BK is a 4.111 auto turbo for Australia [ why do UK dealers need to know that ?? ] The VA codes are on a label [ usually fallen off ] on the diff back cover left side between the two retaining bolts vertically. The T, B type codes are stamped on a flat vertical surface on the right side of the rear diff in the angle where it changes from the nose of the diff to the main case. OR T1, BJ, BK, can be stencilled in in white paint on the top of the diff. But as that area is usually rusty, it ain't much help either. We have never collated the info for the JDM rear diffs as they come marked up from Japan for us. The interweb has any number of transmission identifier sites available. Most centre around USA and Oz and can be inaccurate for JDM info. Especially the US ones as they never see the cars. David APi |

Count the teeth on the pinion gear too and divide the big number by the small number - hey presto!, you're a diff expert.:luxhello: David APi Agents for: Simtek, the most exciting new Ecu for years Buddy Club exhausts Scoobysportexhausts Eibach suspension AP Racing brakes and clutches And of course; the well known APi Performance Exedy organic clutch www.apiengines.com 01926 614333 |

It must be a BJ then - 3.55 (39/11 teeth)
