Hi,
my name is Thilo and I'm from Germany. I want to transplant a MY'97 EJ25 DOHC with 4EAT from a Legacy into a VW Type 2 motorhome (Karmann Gipsy). I'm experienced with the original VW manual transmissions / gear ratios and plan the manufacture of a reversed R&P that should be able to serve in a 2,5 ton vehicle at moderate engine speeds providing a top speed of max. 120kph / 75mph. The intended cruising speed would be around 100kph / 65mph.
Here my questions now:
Where do I get some drawings /geometrial data of the 4EAT differential to get basic dimensions to forward to my gearmaker for discussion?
Can anyone tell me about the gear ratio configuration of a TZ102Z3CAR-DJ and the differential drive ratio? Edit: OK, that's answered by forum search. It should be 4,444 44/9. To achieve the above weight and cruise speed with the gears, the R&P ratio should be in the range of 5,8 to 6,3. Such ratios are available in the VW transmissions.
How can/should I block(?) the original SBR rear drive transmission outlet shaft to have the full torque on the front differential (that will become the reversed rear differential on the VW Motorhome)?
Thank you for helping me, I wll keep you updated on my findings.
Thilo
