I just discovered this website. OMG I wish the budget was deep enough for their twin spark cylinder head and ITB fuel injection for the XJ cars with the straight 6.
I have not inquired about cost. If you have to ask…LOL
Happy dreaming.

I reached out to them about a year ago to get more power for my XJC. That cylinder head is about $15,000.00 and the stroker kit is another $10,000.00… Powerball come on. LOL.

How about this: KWE Digital Engine Management (DEM) – KWE Cars - Jaguar, Daimler and Aston Martin DB7 Restoration Specialists
These guys have a lot of info on their website - take a look.
Piercy, that is indeed eyewatering. Wow! Still, if the funds are ever there, by God it will happen. LoL.

They also have fuel injection for the XJ, another $14,000 and a serpentine belt kit which incudes uprated alternator, and 7 piston AC compressor for $2000. In total a very nice bit of kit!

Unfortunately KWE is shutting down, so I suppose if someone really wanted to get their products they’d need to move now, if it’s not already too late. Just go to their homepage to see.
Hopefully the parts line would live on even if they stop their repair/restoration/modification services, but that remains to be seen.

Their reasoning behind the kits are/were valid, Dave - not exaggerated. But engines are what they are, and no enhancements can do more than
marginally improve power delivery and economy. Other factors may be involved, but the cost makes owners hesitate - unless for ‘prestige’ in its widest sense of that word…
As modern engines, with improvements to engines themselves, incorporates all their relevant factors for power, reliability and economy, their market is, alas, likely too small for sustained operations?
But it’s sad when such specialists disappear…

And brand loyalty, something I fully appreciate while at the same time wondering if it can be taken too far? For more power there are many choices, and more sensible ones.
Alas, when it comes to the car hobby, sensibility sometimes takes a back seat.
I say that as an acknowledgment, not a criticism
