XJ6 and XJS LS Engine Conversions- LS1 LS2 LS3 LS6 LS7

Note to readers:

Kits are now available for LSx engine conversions into 70-87 XJ6 (sedan and coupe) and 76-96 XJS cars.

These articles are here to give you a flavor for what's involved in doing an LS engine conversion on your Jaguar, and I will be adding more on the different aspects of the projects from time to time. After driving my (finished) LS1-Jaguars for a while now, I can attest that the power, torque, flexibilty, and smooth reving of these engines are a perfect match these cars. This is a fantastic conversion opportunity any XJ6 or XJS, and with the information in our conversion manual, and the kit and supporting parts, a Jag owner could do this conversion on his own car easily.
