What an engine rebuild includes
Every rebuild starts with a precise assessment of the engine before any work, so we only renew what truly needs it.
Strip-down and inspection
Engine removal, disassembly and parts inspection to identify the cause of wear or failure.
Parts replacement
Reconditioning of worn elements and out-of-spec parts, with components suited to the model.
Reassembly and sealing
Careful reassembly, clearance adjustment and sealing checks before the engine is run again.
Mapping and fine-tuning
Engine mapping tuned case by case by our engine engineer, followed by control tests.

Our approach to a bespoke engine rebuild
A successful engine rebuild begins with understanding what wore out or damaged the engine, not simply with swapping parts. At Bernis Factory, our engine engineer strips down and inspects each assembly before deciding the scope of the work. Depending on what we find, the rebuild can be partial, on a specific sub-assembly, or full when the engine requires it. This logic avoids needless renewals and focuses the work where it really matters for the reliability of your sports car.
Reassembly is then followed by genuine fine-tuning. Rather than applying a generic map, we tune the engine case by case so it regains healthy behaviour, whether the car is driven on the road, on track or both. It is the same rigour we apply to preparation and restoration: every engine is treated according to the car in front of us and how its owner uses it.
An engine rebuild in Signes, near the Paul Ricard circuit
Bernis Factory is located at 26 Allée de Dublin in Signes, in the Var, 700 metres from the Paul Ricard circuit at Le Castelet. This closeness keeps us in constant contact with high-end sports cars used on both road and track, where a healthy engine makes all the difference. Whether you are from the region or passing through to drive at Le Castelet, our workshop handles your engine rebuild with the same care as the servicing, preparation and restoration we carry out every day.
Engine rebuild for high-end sports cars in the Var
Finding an engine rebuild specialist able to handle a high-end sports car is not straightforward. Many workshops limit themselves to standard replacements, when the engine of a Ferrari, BMW M, Mercedes AMG, Porsche or Nissan GT-R calls for real mechanical understanding. Bernis Factory approaches these engines with the eye of an engine engineer used to stripping them down, inspecting them and tuning them individually, from its Signes workshop.
Engine rebuilds fit within our three trades: servicing, preparation and restoration of sports cars. A cleanly rebuilt engine is often the starting point for a controlled preparation or a complete restoration. It is also a guarantee of reliability so you can enjoy your car over time, especially during track days around the Paul Ricard circuit.
For classic and collectible vehicles concerned by a rebuild, you can consult the references of the French Federation of Historic Vehicles.
Frequently asked questions about engine rebuilds
What is an engine rebuild?
It is the reconditioning of a worn or damaged engine. It involves disassembly, parts inspection, replacement of what needs it, then reassembly and fine-tuning. It can be partial or full depending on the condition found.
Which cars do you rebuild engines for?
We work on the high-end sports cars we prepare and service every day, such as Ferrari, BMW M, Mercedes AMG, Porsche or Nissan GT-R, for both road and track use.
Do you give an engine rebuild price online?
No. A rebuild depends on the engine, its condition and the required scope. For an estimate suited to your car, the simplest step is to describe your project and contact us directly.
Is the rebuild followed by engine mapping?
Yes, when relevant. After reassembly, our engine engineer tunes the engine case by case rather than applying a generic map, so it regains healthy operation.
Should it be a full or a partial rebuild?
It depends on the inspection carried out at strip-down. If wear is concentrated on one sub-assembly, a partial rebuild is enough. If the engine is more tired, a full rebuild is preferable. We decide after diagnosis, with no needless work.
