What This Service Involves
Jaguar R and SVR models demand a higher level of precision and care during engine rebuilding. Our performance rebuild service combines the full standard rebuild process with extra steps specific to supercharged, high‑output engines.
Core Rebuild Process
- Full strip-down – the engine is completely disassembled, with every component labelled and inspected.
- Machining to factory tolerances – cylinders are bored and honed, surfaces resurfaced, and all critical dimensions restored to OEM specifications.
- Inspection and component selection – all parts are measured and assessed; worn or out‑of‑spec items are replaced with genuine Jaguar or equivalent‑quality parts.
- Precision reassembly – the engine is rebuilt using factory procedures, with absolute attention to torque settings, clearances, and alignment.
- High‑load road test – after installation, the vehicle undergoes a full road test to verify performance under real‑world conditions.
Performance‑Specific Considerations
- Supercharger servicing – R and SVR models use Eaton TVS superchargers (on AJ126 and AJ133 engines). These are rebuilt as part of the service with new bearings, fresh supercharger oil, new seals, and a replacement coupler.
- Absolute precision assembly – with outputs up to 575 PS in SVR specification, every clearance and torque setting must be exact. We work to Jaguar factory specifications using OEM tools and procedures.
- Component quality – we use OEM or OEM‑specification parts. Where appropriate, we may fit upgraded components for enhanced durability under sustained performance driving.
Starting Price
Performance engine rebuild starts from:
- AJ126 Supercharged V6 (F‑Type V6 S): from £3,600
- AJ133 Supercharged V8 (R models): from £5,500
- AJ133 Supercharged V8 (SVR models): from £6,500
Final cost depends on condition and any additional parts required. We provide a fixed‑price quote after full inspection and strip‑down. View pricing disclaimer →

FAQs — R / SVR Performance Engine Rebuild
What does a Jaguar R/SVR performance engine rebuild involve?
A full performance rebuild includes complete engine strip‑down, inspection, machining to restore OEM tolerances, reassembly with OEM components, and a high‑load road test. For supercharged R/SVR engines, we also rebuild the Eaton TVS supercharger – replacing bearings, oil, seals, and coupler.
Which Jaguar models does this apply to?
This service covers all Jaguar R and SVR models including F‑Type R/SVR, F‑Pace SVR, XFR/XFR‑S, and XJR – all equipped with the 5.0L supercharged AJ133 V8. We also offer performance rebuilds for the supercharged AJ126 V6 where applicable.
How long does a performance engine rebuild take?
Typically 3–5 weeks depending on parts availability and machining requirements. We provide a clear timeline after initial inspection and strip‑down.
Do you use genuine Jaguar parts?
Yes – we use OEM or OEM‑specification parts. In some cases we may recommend upgraded components for enhanced durability under performance driving, and we discuss these options with you beforehand.
Is the supercharger rebuilt as part of the service?
Yes – for R and SVR engines, we rebuild the Eaton TVS supercharger with new bearings, fresh oil, new seals, and a replacement coupler as part of a comprehensive performance rebuild.
