My google mojo is failing me...

In Another Place, conversation has turned to the R&D work Honda did in
the late 80s to build a 250 fourstroke turbo GP racer, to race in the
500 class [1]. I recall that they got it running on the bench, and it
made the right amount of horsepower (180ish), but was physically too
complicated (with rads and intercoolers etc) to fit onto a racing
motorcycle.

But can I find anything decent on the web about it? No, I can't. See
if you can do better.

[1] Like F1 in those days, turbo engines could only have half the
capacity.

You probably found this:
"Accordingly, in 1983/84. Honda developed a 250 cc V-twin turbocharged GP
engine, based on the NR concept, with eight valves per cylinder and oval
pistons - but this had not been seen in public at the time of writing."

I recall reading an article that two had been seen road testing
in outback Queensland, probably in Revs:
