racing and safety AlpinA 2oo2 LSD resto

[markmac]

I started this project months ago thinking I was going to need my diff all done for the Monterey event earlier this month.  When it became apparent back in June that there was no way my car was going to be ready I put the brakes on everything I was doing (by brakes I mean not stopping but just taking my time).  Sometime after AlpinA sold my car to Ricciardo Ricci, and then he turned the car from an endurance road car to a hillclimb specialist, he changed the diff to a 5.86 factory set-up.  5.86 gears are useless to me (and in addition both the ring and pinion were missing large chunks of metal out of a number of places on both). Thanks to KBM02 I secured a really nice 4.11 gear set and engaged Pete (Pete's Gear Shop, Hayward, CA) to do the re-build.  The diff has a AlpinA (factory) 75% LSD as well as an AlpinA 1-stage oil pump.  Pump is driven off the axle (V-belt is not installed at the moment).  There are two (2) twelve row oil coolers that are mounted to the rear axle to cool the diff.  There is also a pulley mounted on the front yoke that drives the alternator which is mounted in the trunk.  Will be posting more images and some before/after on my blog later this weekend for anyone interested.
