So, are you saying that the 4HEAT in USDM '94 SVXi and '95 L models without ABS all had 3.70 gear sets and the VTD setup? Up to now, I was under the impression that you had to source a 4HEAT from Japan or Australia to get VTD.
Thanks

In any case, my point is that the car tracks much better. It seems that the geometry of the rear suspension is well suited to handling more than half of the torque, and the car really "feels" more like it is going where you point it instead of going where the front wheels are pulling it. It is difficult to describe.

As for which models had what:

All US models were 3.545 full time active MPT based AWD (ACT-4) EXCEPT:

1994 LE, L, LS models
1995 L models WITHOUT Active safety group option

JDM and AUS cars are VTD, along with some other regions. I believe germany got the ACT-4 where much of the UK got the VTD. Someone feel free to chime in here that knows the exact regions. The AUS VTD trans uses a different TCU and an internally mounted speed sensor no. 2. I believe one or two have modified it to work with the external unit.
