From Weird to Wonderful - the World of Climax and Imp-based
Specials.
Part I. Climax-based Specials

When we said we were going to do another book about Imps they said
"you must be crazy". But then we told them it would be about Climax
and Imp-based specials and kit cars. The ``seen-it-all-before''
expressions turned into mildly interested silence followed by the
occasional question over the intervening years. Undeterred we plodded
on, wading through magazines, notebooks, pestering former owners, and
following up rumours. No doubt there will be a car in your back
yard which deserved a chapter all on its own, and we didn't even known
it existed, but we have tried.
In the 1960s and 1970s the Imp was one of the most widely used cars
for the design of specials, second only to the ubiquitous Mini Cooper
and the VW Beetle with which it shares the rear-engine layout,
directly bringing it closer to more exotic beasts, such as Formula
racers of the post 1950 period. In the under 1000cc and under 1300cc
competition classes Imp-engined specials became pre-eminent, ousted
more recently only by cars constructed around Japanese motorcycle
engines. The Coventry Climax engined John Cooper and Lotus cars have
of course been the subject of many books in their own right, which we
cite in the bibliography. There are however many less well known
racing specials with Climax engines and they are described in Part
I on Climax-based specials.
We have attemped to list all Imp-based cars (and other devices) which
came to light during our research, no matter how obscure. In addition
we hope to show you in the following pages something of the zest with
which amateur, as well as professional, constructors went about taking
one of the best designed small cars of its time and ``improving''
it. The outcome of some of these experiments was an unqualified
success in racing and sports car circles. Others - well you can draw
your own conclusions ...
