[xj-s] V12 swap for XJ-6...is this crazy?

["Vincent A. Eng" <veng@bernan.com>]

I just purchased a 1994 XJ40 (XJ12) last month.  1994 is the only year they made the
XJ12 with XJ40 body style.  The 1994 XJ12 model was produced in two styles - one had a
glovebox and was fitted with XJ-S sport wheels (early production) and the second had
an airbag instead of a glovebox and had the 16 inch 20 spoke wheels.  I thought it was
bad that the XJ-S had no glovebox light.  The XJ12 manual actually recommends using
the trunk as the glovebox - there is even a strap in trunk to hold the manual.

I compared the engine bay size of the 1993 XJ40(V6 4.0) with the 1994 XJ40(V12 6.0)
and they are identical.

1988 XJ-S H&E
1994 XJ12
1993 VDP
1996 BMW 750iL
1995 Volvo 854T5-R
1984 Ferrari 308 GTSi


Matthias - Thanks again for that cover.  After the major overhall the XJ-S has been
running great.

No, there was (according to my recollection of fact) no XJ12 between the
Series 3 and the X300, as the XJ40 engine bay was too narrow.  This was
reportedly to stop British Leyland from  fitting the Rover V8 into the XJ40
in place of the AJ6.
