Except bold and pioneering installation by Mike Rodrigues, has anyone else used ZF 5- DS-25 series transmission in Esprit?
Apparently, wide range of gear ratios are available from this company: http://www.rbttrans.com/
ZF requires a new bellhousing, which is prototyped and available from NZ foundry.
A group buy could be arranged if 10 buyers would commit to purchase.
Bora's had 3.77:1 ring and pinions in them instead of the 4.22:1 that a Pantera uses!
Panteras used the ZF well into the 90's!
