It may be day late, but this R31 is worth the delay. Ken lives in Okinawa and sent us a photo of his R31, which just happens to be his first car. Over 14 years of ownership, Ken has swapped in an RB26 (with a T88 turbine), S15 and R33 suspension, and R32 GT-R brakes just to name a few things. Outside it has R31 House FRP trunk and hood, a Racing Silhouette aero kit, and bolt-on over fenders.
Ken uses the car as his daily driver and for the occasional drag race event.
Awesome.
