Help please. I have jaguar xjr x308 of 1998. I had a knock in the motor. I decided to change the engine for the engine of 2001. When replacing the engine I found a difference in camshaft sensors. In 1998 there was one sensor, and in 2001 their two. As to install me the motor of 2001 on my jaguar xjr x308 of 1998 with one sensor. Whether I will be able to start the motor of 2001 with conducting, both the control package and the sensor of 1998. Sorry for my English

 

Welcome to the forum. You are replacing an AJ26 engine with an AJ27 and there are several differences. There have been several threads dealing with this and you will probably find them using the search function. Others will probably be able to supply you with information based on their own experience.

The cam sensors, the injector bypass air, but most importantly, the flywheel reluctor ring are all different. On an XJR, I believe you will be able to the original cam pickup pulse trigger, the intake manifold and injector rails, the throttle body, the flywheel, and the ignition coils and you will be in business. The NA model is much more complicated due to the VVT.
