Is anyone aware of anyone ever transplanting an X300 XJR6 engine into a 6 cylinder XJS?
I know there would be some computer/electrics issues, but I assume it would be possible.

 

This has come up before.

One of the fellows on Jag-Lovers is, I think, in the midst of such as project.

I think there is one other such car out there somewhere...perhaps in the UK.

The electrics are tricky but, as I understand it, just getting the engine to fit is quite a challenge, thanks to the extra bulk/width of the supercharger and associated plumbing.

while you're at it, you might want to investigate a stand alone management for the supercharged 6

 

Or buy a Aston Martin DB7 which has that exact engine in it from the factory.

 

There was an XJS for sale in Australia on ebay last year with an XJR6 engine installed. Pity my garage is full

 

I second that. Prices for the DB7 are ridiculously low and a manual transmission is available. Probably would spend less to do that than to do an XJR engine swap.

 

From memory the DB7 was a 3.2 supercharged.
I was thinking of the 4 litre XJR6 engine, but you all make a good point.
I remember the talk when the Aston was released that it 'had a Jag engine', which is almost as annoying as those people that say Jags were 'just a Ford'...

Anyway, if the DB7 was based on the AJ16, how much of the engine differed from a Jaguar engine?

 

Plums, that was the first thing I thought of! Ha. I still think it would be a great project to see a XJR6 mill in the XJS hull. Keeping it all Jaguar!

 

Hi

There is such a car in the uk and it is owned by Clarkes XJS and I believe for sale, It might be worth ringing Dave Clarke for more info on the conversion
