Yes mate, RB20DET, stock crank, stock rods, stock inlet manifold, and so on as per Group A rules at the time.
RB20s have mega thick cyl walls, mega short stroke, a brilliant rod ratio, tuning wise they are strong as hell and built to rev. Just the super short stroke means they have cock all low down, but hey, no 2ltr has really.
Wish low mount mani's like that were widely (cheaply!) available, but they not common anymore.
JDM Garage had an old Blitz one that looked just like the above ones for sale few weeks back but its gone now IIRC.
