Frequently Asked Questions
Our XKR-S 5.0L V8 Supercharged engine rebuilds cost £7,500–£8,200, including fitment, ECU reset, road test, and 12-month unlimited mileage warranty. This covers the specialized components required for the high-performance supercharged engine.
Yes - the XKR-S features a more powerful 550HP version of the 5.0L V8 Supercharged engine (AJ133) compared to the standard XKR's 510HP. We've rebuilt over 120 XKR-S engines since 2017, focusing on the specific supercharger and cooling system requirements of this high-performance variant.
Absolutely - with our rebuild that includes upgraded supercharger components and reinforced cooling systems, the XKR-S becomes highly reliable for regular road use. We've implemented specific protocols for street-driven XKR-S models that address the common failure points seen in vehicles used primarily for commuting rather than track use.
The most common cause is supercharger drive belt failure due to high-temperature stress, often compounded by inadequate cooling during spirited driving. We address this with upgraded supercharger drive systems and enhanced cooling solutions specifically designed for XKR-S applications, including updated turbo actuator LR072310 where applicable.
Yes - we use Autologic and JLR SDD tools for full ECU coding of XKR-S performance systems, including supercharger management, throttle response calibration, and track mode settings. Our technicians have specialized training on the AJ133 engine's performance electronics, which we handle at our Billericay workshop.
The XKR-S benefits from using high-quality synthetic oil (Jaguar specification) and more frequent oil changes (every 5,000 miles) if used for spirited driving. Our rebuilds include upgraded oil cooling systems specifically for track use, and we provide detailed maintenance guidance for XKR-S owners at our Unit A5 Windsor Road facility in Billericay.
