I know it's been discussed many times but I'll go for it anyway.

Going to put an XKR 4.0 litre engine into my XJS racing car. I've got a 6 speed S Type gearbox. Looking at an XJR in the week.

There's an Aluminum flywheel listed for a 4.2. Is it the same as a 4.0 flexi-plate does anyone know?

Can I use the Jag ECM? I know it needs to talk to the gearbox but I won't be running Abs Trac etc.

I'm wondering if it's easier to junk the lot and get a standalone ECM. The problem with that is the Jaguar electronic throttle body.

Interestingly I've read about the twin screw conversion and I believe he's still running the standard Jag ECM.
AVOS is making great power and using a standard ECM? Is this right?

Any help and advice greatly recieved.
Once completed I'll be happy to share costs etc of the conversion.
If I can do it with the standard Jag ECM this will help other users if they want to convert their own car.

Thanks for reading.
Mel

 

These folks just did a manual conversion and have access to a kit supposedly.

Thanks enderle. Tom is on my list of people to speak to Monday. I had read that thread.

As a side note does anyone know the weight of a XKR engine vs a V12.
My engine has a lot of ancilliaries removed. I'm interested in the weight saving of a v8.
