Conversion to Fuel Injection
Hi all!
I know this probably isn't a fan favorite here, but my dad and I discussed converting the carburetor system on our 1969 S2 FHC to fuel injection a long time ago. We never did it and my dad has since passed, but I was curious if anyone had done this or had heard of anyone doing it? I have a friend I work with who did a similar conversion on his old Impala and he loves it, and says it really helps the car start easily and idle great all year round. Below is a link to a kit I had found online to make this conversion. If you've done it, was it difficult, and was it worth it? If you haven't, have you heard anything about the conversion? I'm not making any plans to do it anytime soon since the kit is over $2,000, but figured I would ask and find out. Thanks for the feedback!

Hi Etypefancierjr,
I have never done it but Jason who owned XK Unlimited, I forget the name of his new company. Anyway he'd fuel injected a MK 10(3 throttle bodies) and I believe some V12's with Borla throttle bodies. Here is a link to Borla

I know others have done it with XJ6 systems but they had to modified the manifold a lot to make it fit a E-type.

Not sure what you are trying to achieve with fuel injection.
If you are concerned about miles per gallon then buy a late model Toyota Camry or similar. I have a Mitsubishi Colt called "Shopping Trolley". Does 38 miles per imperial gallon around town (3! mp US gallon)
The best I have ever seen on a S3 XJ6 4.2 fuel injected engine is about 21 miles per imperial gallon or 17 miles per US gallon.
The carby equipped Series 2 XJ6 would do18 miles per imperial gallon or just under 15 miles per US gallon. That engine is basically the same as fitted to your S2 FHC.
So spending $2000 to save 3 miles per gallon on a vehicle which is not an everyday driver does not make economic sense.
In addition, E Type values are still increasing and the people with the money don't want a butchered up vehicles. Unrestored but still original intact vehicles attract higher prices.
Leave it as it is and enjoy some old-world motoring
Keep your E type "stock standard".

Well, I agree originality is one thing for a classic, but...

The result is better than I imagined. The car will sit for a week, I can turn the key and it starts and is ready to go immediately. I think few drive these things for economy, and I don't mind choke, nursing the throttle and the smell of a flooded engine but I still have a MGB for that. The EFI configuration is considerably more comfortable for me and not exactly modern. The induction was lifted form a late 80's XJS, still 35 years old. I'll call that classic as it needs to be.

But......
We've often seen that nicely engineered and executed mods and upgrades are not necessarily considered butchery in the eyes of classic/hobby car buyers.
For decades now, in XJS and XJ sedan circles, it was ballyhooed that resale value will inevitably be utterly destroyed by "lumping" the car with a V8. The ballyhooers, it turns out, have oft been eating their words as many lumped cars have sold at surprisingly high prices.
In any case there is more than one way to enjoy ownership of an old Jag. Some owners are more focused on "hobby" than "investment".
Vive la différence ! :-)

I agree that putting a V8 in XJs and XJS is a good move, especially if it is replacing a clapped out V12 or even an XK6 engine.
I advocated this locally a couple of decades ago and the purists howled "sacrilege!".
The facts were that you could at the time go V8 for around $5K, A 6cylinder XK engine rebuild was passing $6K and a V12 rebuild was $10K+
My message was that particularly the older V12 cars would be saved.
I am not against modifications.
I have a 1960 MK2 2.4 manual which has been modified with a HD6 Carby system off a 3.4 engine, diff changed from 4.29 to 3.77, late model full synchro gearbox with overdrive, S type seats.195X65X15 tyres.
All these improvements made a "slug" into a useable car, (the Carby change was an approved factory mod.)
However, I still believe keeping an E type original as possible is the way to go.
A friend I am helping currently has his Series 2 E type stripped out on a rotisserie. We had much discussion about possible modifications however it will end up remaining "stock"

Putting a non-Jaguar V8 into an XJ or XJS is something to do because you can't do any better. I'll not condemn anyone for it, but I'm not going to congratulate them either.
Converting an E-type to fuel injection or ECU controlled ignition is fine with me. Done wisely, it's easily reversible. It's something the Jaguar engineers of the time would have done at the time. Done well, it can improve the car. Put it another way, no one blinks at a bolting a bunch of Webers on an E-type - or if they do, it's in admiration. They might give an extra 10hp at 5,000rev/min while losing power and economy everywhere else. So why is there disapproval for something that's a genuine improvement and fun to do?
