Anybody supercharged an AJ16 in an XJS?

[cml]

This must have occured to somebody else. Taking the supercharger from a XJR and putting it on the AJ16 engine in a late model XJS. It is the same engine is it not?

Anyone heard of such a thing?

TWR did it.

It's called the DB7.

I expect that AJ6 superchargers will have done it if anyone has.

I had a look at the AJ6 website and price list, there's nothing on the AJ16 engine. They will supercharge things for you, but that side of the business appears to be an expensive bespoke operation aimed at competition cars, rather than a 'get hold of an old XJR engine (if there are any about!) and this conversion kit and off you go'.

There was an article in the Jaguar Enthusiasts Mag recently with someone who had done this. Unfortunately I don't remember when it was (within last year though)

Might have a dig at the weekend, or you could try asking for a back copy.

Oh, I would love to see that article!

You cannot just bolt one on,
the compression has to be lowered for one thing, also the engine management

Sorry, can't find it. Might have already given my copy away.

IIRC, the guy swapped in the complete engine with supercharger from an early XJR (Original supercharged XJS was 6-cylinder). Also needed ECU and some other stuff. Remember the immobiliser was a pain to solve. I also think he lived up Newcastle way.

Google search reveals it was November 2004! I recognise the cover as one I might have seen just now. Will look again at the weekend!!!

Cheers. Yes I thought of all the ECU gubbins while walking home. This is the most modern car I've had and I forgot that you can't just do what you want to an engine anymore. Looks like a big project then. A complete engine swap might be better than trying to fit bits.

Found it!

I recalled correctly, the owner swapped in a complete engine, supercharger, intercooler, ECU, engine wiring-harness, rad etc.

Email me your address, and I'll pop the mag in the post.

Sheepy

Got magazine - thank you very much!

It does look fairly involved and would require a good garage who knew a thing or two, plus a sizable pile of money. Perhaps one day. It did look terribly

It says at he end of hte article that the car is for sale (it was 2004 though).

I wonder where it is now. I hate to think it but it probably went into a ditch!

An engine swap is a MUCH better an cheaper idea because a supercharging isn't simply bolt on, rememeber the PISTONS are of lower compression design on the R variants.
