How viable do you think that is?

I'd suggest an X300 XJR engine and box - far far easier. Have a look on the MK11 forum an see how all wiring needs to be installed, including door lock electronics. Not to mention fabrication.

The 6 cylinder car is less complex, less prone to the issues and 330bhp. The AJ6 will drop in with no fuss. Another superb engine from Jaguar imho.
Love them coupes...

Thanks Sean!

Do you know of anyway to boost the hp a little up to 400hp? The XJC is already near 4000lbs and i was also considering a broad speed fenders... I know i know... its a pristine coupe...

Love the looks, however looks like serious cancer in the rear quarter panel..

I am putting a XJR V8 into a XJS but I love XJCs and would not blink at doing it, would be an amazing car
