At HWM Works, we specialise in Aston Martin engine rebuilds, performance upgrades and bespoke engine builds for modern Aston Martin road and race cars. As the world’s longest-serving Aston Martin dealer, our engineering team combines decades of Aston Martin expertise with meticulous in-house craftsmanship to create engines of exceptional quality, reliability and performance.
Every engine is completely stripped, inspected, precision measured and rebuilt to exacting standards using motorsport-informed processes and blueprinting techniques. Whether you require a standard Aston Martin engine rebuild, a performance upgrade, or a complete bespoke specification, HWM Works delivers a level of engineering and attention to detail beyond conventional remanufacturing.
We regularly work on engines fitted to the following Aston Martin models:
Aston Martin DB7, Aston Martin Vantage, Aston Martin DB9, Aston Martin DBS, Aston Martin V12 Vantage, Aston Martin Rapide, Aston Martin Vanquish, Aston Martin Vanquish S, Aston Martin Vantage GT12, Aston Martin Virage, Aston Martin DBS Superleggera and Aston Martin DBX, alongside specialist motorsport applications.
From naturally aspirated V8, V12 engines, pressure-charged engines, through to race-derived performance builds - every project is completed entirely in-house under uncompromising engineering standards.
Please note, all price shown below are inclusive of VAT.
As an official Aston Martin dealership, HWM can also supply factory Aston Martin re-manufactured engines. However, we strongly believe that a carefully engineered rebuild offers significant advantages over replacement.
Each engine is meticulously balanced, measured and assembled to deliver exceptional drivability, refinement, and durability. Our blueprinting process ensures every critical tolerance is optimised, resulting in engines that consistently exceed original factory feel and performance.
Unlike a conventional replacement engine, a rebuild also allows us to tailor the engine to your exact requirements, whether your priority is improved road response, enhanced torque delivery, increased top-end performance, or long-term reliability.

While factory re-manufactured engines remain an excellent option, many customers choose HWM Works rebuilds for the additional craftsmanship, performance optimisation, matching-number retention and extended warranty coverage.
We have been delighted by the overwhelmingly positive response to HWM Works. Due to the level of demand and the time dedicated to every individual engine build, our programme is currently operating with a waiting list.
This reflects our commitment to delivering every engine to the highest possible standard rather than compromising quality for volume.
We encourage you to contact the HWM Works team to discuss your engine rebuild, performance upgrade or bespoke engine project in more detail.
To discuss your Aston Martin engine rebuild, performance upgrade or turnkey installation project, please contact the HWM Works team.

We would be delighted to discuss the best solution for your car.
How long will it take to rebuild my Aston Martin engine?
Lead times vary depending on workshop demand, engine specification and the condition of the donor engine once disassembled. As every engine is individually inspected and engineered to the highest standards, the exact scope of work is not always fully known until the engine is stripped and assessed.
As a general guide, most Aston Martin engine rebuilds are completed within approximately two months. Please contact the HWM Works team to discuss current lead times and scheduling.
Can I speak to someone about my engine project?
Absolutely. We are always happy to discuss your engine build, performance goals and upgrade options in detail.
You can speak directly with our engine building manager, whose depth of engineering knowledge and experience is exceptional. Conversations often begin with a standard rebuild and end with something rather more exciting.
How do I get my engine to HWM Works?
You are welcome to use your preferred specialist to remove, transport and reinstall your engine.
Alternatively, HWM Works can provide a complete turnkey solution including vehicle collection, engine removal, rebuild, reinstallation and commissioning.
How does pricing compare for V12 engines and AMG V8 engines?
There are many different engine variants and specifications, making it difficult to provide universal pricing guidance online.
The Aston Martin V8 Vantage examples shown above provide a useful indication of the level of engineering involved and how our rebuild pricing compares favourably with factory re-manufactured engine options, while offering the additional benefits of blueprinting, upgrade opportunities and extended warranty coverage.
Please contact us to discuss your specific engine and requirements.
Will you rebuild engines from other manufacturers?
Yes. While Aston Martin engines remain our core focus, we have extensive experience working on a broad range of high-performance and classic engines from other manufacturers.
Alongside road engines, we have also built and supported a number of successful motorsport and race engine projects.
How do I know my rebuilt engine will be stronger?
Every HWM Works engine is precision measured, blueprinted and assembled using carefully selected components and exacting engineering standards.
This meticulous process allows us to produce engines with exceptional reliability, consistency and strength. For customers requiring validation testing, we can also arrange independent dyno testing at additional cost.
