V160 wasnt too hard to fit. As noted from http://turbosupras.com/pages/pages/t...onversion.htm:
Not too hard but took a bit of putting the engine in and out. Only modification to the tunnel apart from making those two sections slightly bigger was moving the shifter hole about a inch to the rear of the tunnel - nothing major at all!Firstly, the left hand side gearbox tunnel mount point needs to be hit with an engineering stick (hammer) mid way up, this is due to the R154 being larger on 1 side, thus the tunnel is not centred down the middle of the car.
The second spot is on the right hand side, around 36mm (1.5") in front of shifter hole, a firm hit with the engineer's stick will be plenty.
