Decided to splurge and buy another gearbox. Taller gears and bigger ring gear.
3.750 vs the 3.556 ratio.
Current box code is HCF. Swapping to an HCK
Will also be installing likely a quaiffe diff into it.
It's funny no retailers technically sell an lad off the shelf differential for the audi 01x diesel box but with careful research.
The diff is 100% identical to the like gen 2 boxster/cayman.
The 97-99 uses the smaller bearing or side cover but the 2000-2004 I believe is the same!
Diff part # borrowed from 1 another !
So the quaife 16 diff should drop right in.
I tried to find a used one for a while but have wince given up, so once I get this box opened up and give ir a good bill of health I'll pull the crown off the stock open diff. Order up a new quaiffe diff. Install new bearings. Reset the diff for backlash and preload and call it a day!!
Happy weekend folks
