Both of these Alts came directly off Diablos, one a 93, the other a 98.
They both have the original Bosch stickers still on them and I checked, both regulator/brush pacs have the same part # on them. So the ones playing games is not Ultimate, it's Bosch and Lambo
But we've always known there was some game playing going on right
BTW: the last Bosch 928 part numbered Alt I bought ( from Bosch) was around $465 plus a $100 core charge, plus frieght both ways...so the real cost adds up quick.
ps: if you want to do a real test use those 928 part #'s and call a Porsche Dealer for some prices ...I think you will be surprised at their prices.
