I have found some information on the V160 into MkIII swap through researching a 2jzgte swap into my GZ20 soarer.
Bassically there is very minimal transmition tunnel beating and a shortening of the remote shifter. The hardest thing on the swap is the speed sensor. The
v160 uses an electronic sender unit that sits on the oposite side of its driving worm gear compared to the R154 sender this means it is spinning in the reverse direction. It also has 31 teeth on the sender unit compared to the
R154's 33.

Also the diff ratio's in the A80 is 3.266 for the JDM and 3.133 for the export models. This makes use of the very short ratios of the gearbox.
For me the conversion at the moment is in its planning stage, but more than likely i will go R154 for the simplicity of the conversion and its ability to adapt with other standard toyota parts.
Now i need to work out how to wire a conversion!
