According to Wikipedia:
Jaguar_AJ-V8_engine
4.0 L
The 4.0 L (3996 cc) AJ26 engine was introduced in 1996. The number "26" comes from 12+6+8 (cylinders), because when the first ideas were sketched, a family of 6-, 8- and 12-cylinder engines was contemplated, although only the 8-cylinder version was produced. It has a square 86 mm (3.4 in) bore and stroke. It was updated in 1998 as the AJ27 with continuously variable valve timing. The AJ-V8 was updated again in 2000 as the AJ28. The naturally aspirated version produces 290 hp (216 kW) in the 2000-2002 XK8.

Supercharged
The supercharged version of the AJ26 is used in the high-performance R versions of Jaguar's cars. The engine was updated with AJ27 specifications for 2000. It produces 375 hp (280 kW) and 387 lb⋅ft (525 N⋅m) with the help of an Eaton supercharger (modified Roots-blower). The supercharged engine did not use variable cam timing as the normal benefits of improved volumetric efficiency are not noticeable on a boosted engine

What does this superchargerrebuild kit process include?
You, the buyer will havethe parts that you need to replace the nose drive seal yourself. Technical support from theESM Shop Foreman is available during normal business hours by contacting usthrough the message center in . Our main shop phone number is available onour company website.
What are some importantprocess points that can help with the rebuild process?
- The inside race of thefront nose drive ball bearing must be supported when installing the shaft. Thismeans the shaft must be installed before the front nose drive seal is installedbecause the front nose drive seal will cover the inner race of the front nosedrive bearing when the seal is installed. If you do not support the inner race,it will result in installation damage to the ball bearing. A clicking noise inthe bearing after installation is a symptom of this.
- Never use ball bearingswith dust covers because in this application they are used in an oil bath.
