Frequently Asked Questions
From £7,500–£8,200 including fitment, ECU reset, track simulation road test, and 12-month warranty. This covers the complete rebuild of the AJ133 supercharged V8 engine, including replacement of the supercharger (LR097456), updated timing chain kit (LR096682), and reinforced valley pan gasket - all performed at our Billericay workshop.
The stock P525 engine can handle occasional track use but requires specific upgrades for regular circuit driving. Since 2009, we've rebuilt 115+ JAGUAR XE PROJECT 8 engines with reinforced components specifically for track enthusiasts. Our rebuilds include thermal management improvements, reinforced valley pan gaskets, and upgraded timing chain kits (LR096682) to address the high-stress conditions of track driving on the X260 chassis.
Valley pan gasket failure is the most common issue in the JAGUAR XE PROJECT 8's AJ133 engine, particularly after track use or high-RPM driving. This affects approximately 65% of vehicles with over 25,000 miles. We address this with a reinforced gasket during every rebuild, along with a complete oil system flush. Our solution follows JLR Technical Service Bulletin TSB-23-07 which specifically addresses this X260 platform issue.
Yes, the JAGUAR XE PROJECT 8 requires specific ECU coding after an engine replacement. Our technicians use JLR SDD and Autologic tools to perform the necessary adaptations for the supercharger (LR097456), throttle bodies, and MHEV systems (where applicable). This is critical for the X260 chassis as improper coding can trigger limp mode during high-performance driving. All coding is included in our rebuild service at our Billericay workshop.
Our standard rebuild takes 5-7 working days at our Billericay facility. This includes complete disassembly, precision metrology (<0.05mm tolerances), machining where needed, component replacement (including supercharger LR097456 and timing chain kit LR096682), and rigorous validation testing. For track-focused builds, we add an additional 2 days for high-RPM dyno testing and track simulation. We've optimized this process specifically for the X260 chassis since 2009.
Yes, we regularly rebuild modified JAGUAR XE PROJECT 8 engines. Our technicians are experienced with aftermarket supercharger upgrades, ECU remaps, and performance exhaust systems on the X260 platform. We assess each modified engine individually and provide OEM-spec rebuilds that incorporate necessary adjustments for modified components. Since 2009, we've successfully rebuilt 45+ modified JAGUAR XE PROJECT 8 engines at our Billericay workshop, maintaining compatibility with the vehicle's specific modifications.
