Almost any bike.

Or if you want cars - Toyota 3SGE (in the MR2 Mk2 among others), 2
litres, 158BHP from the later UK models, and over 200 if you can get hold
of one of the Japan-only BEAMS engines. Though the last does have
variable valves etc...

Or the BMW 320, 150BHP/ 2 litres from 1991.

Or IIRC the Cavalier GSI, 156 BHP, 2 litres, and that's back a few years.

Thse are pushing 75bhp/liter and are RARE. I did have an astra SRI wahich
was quite a lively injected 1.8 liter engine...otherwise it was deeply
dull.

So, the BMW engine is rare? Do you drive around with your eyes shut?

Another example from a few years ago - PSA 1.9 16v engine, 1905cc, 160 bhp.
So 84 bhp/litre, over 10 years ago. No variable valves, and it was a
reliable engine.

None exceeds 100bhp/l;iter.

True. Those examples are all from 10 years ago.

Let's look at some more recent stuff. Peugeot 206 - 180hp from 2 litres NA.
Renault clio - 200 hp from 2 litres NA.

2001 - Honda civic type R. Rather popular hot hatch, probably because of the
197hp from a 2 litre N/A engine. (the S2000 is 237hp from the same size
engine).

Now obviously these are all at the quick end of the market. But they're
there, easy to get hold of, and reliable. Which sort of makes your
contention that 70 bhp/litre is rare a bit wrong.
