Welcome to UCP!
This is just my opinion but, I think if you supercharge a XJS it means you don't vale the car as it deserves. It is a classic and not Supra or something you can mess with. Keep it stock and respect it's heritage.

Not true. Although the XJS is definitely a classic, there are proven ways to improve its lackluster performance and make full use of all those pistons, all of which can be done without 'ruining' the car. There is actually a sizeable aftermarket for them.

What year are we talking about? First gen (75-83) or second (83-91)? Convertible? Coupe?

The most likely place to get such info might be the UK Jaguar Owners club.

Nice car. Doesn't tuning mean improving the engine? Or what do you mean by tuning it? I still think it's a crime.
