FTFY
Now I was being flippant with the 4 seconds comment which perhaps people have taken too much to heart here.
Still, in the same way that a Lotus engine was dropped into a Talbot Sunbeam to great effect (250bhp in rally trim) back in the day, there are plenty of cars out there that could cope with a bit more speed.
There are plenty of modern cars trying to put over 200bhp in a front wheel drive chassis which rely on software to tame the result.
The Capri is an interesting example. It still boggles me that basics like panhard rod were an optional performance "RS" extra, but they could go if they were properly fettled.
So yeah, you would have to choose carefully. I imagine an electric X1/9 would be straight into the nearest tree. OTOH, imagine the battery range you could fit in a big American land yaught
