Second Hand Ford Sierra Turbo

The Ford Sierra ran from 1982 to 1993, with a significant facelift in 1987 that introduced a restyled front end and various mechanical updates, so the generation boundary to be aware of is pre-1987 versus 1987-on. The engine code is the single most reliable guide here — if the donor car shares the same engine code as yours (shown on your V5 or via a VIN check), the turbo itself is likely to be the same unit, but whether ancillary brackets and mounting points align across the 1987 facelift boundary is something you should confirm with the breaker against your registration before buying.

The XR4i used a naturally aspirated 2.8 V6, while the Sierra Cosworth used a turbocharged 2.0 Pinto-derived Cosworth YBB or YBD engine, so the two turbos are completely different units and will not interchange. Always match by engine code rather than badge or model name — the Cosworth turbo is specific to the Cosworth engine family, and a breaker will ask for your engine code as the first step to finding the right part.

Trim level itself does not affect turbo fitment — what matters is the engine code, and a Ghia or base-model Sierra running the same engine code as another variant would take the same turbo. The RS Cosworth is a distinct performance model with its own dedicated turbocharged engine, so it is really a different engine family rather than just a trim difference; always quote your engine code to the breaker so they can match the correct unit rather than going by trim name alone.

A 1986 car is pre-facelift (the facelift ran from 1987 onwards), so there is a generation boundary between those two cars, and while the engine code remains the most important factor, ancillary fittings and mounting details can vary across that 1987 boundary. Confirm with the breaker using both your registration and engine code — if the engine codes match they will be best placed to advise whether the specific turbo from a pre-facelift donor will bolt straight onto your post-facelift car.

Give the breaker your engine code (found on your V5C or via a VIN check), your registration number, fuel type, and gearbox type — these are the details that actually determine which turbo fits, not the body style or colour of your car. Year of manufacture is also useful, particularly to flag whether you are pre or post the 1987 facelift, as this can affect ancillary and mounting compatibility.

The turbo unit itself is driven by the engine rather than the gearbox, so in principle gearbox type does not directly determine which turbo fits — engine code is still the primary guide. However, confirm with the breaker that no ancillary differences exist on the specific donor vehicle, as plumbing and bracket configurations can occasionally vary by market or build date regardless of gearbox type.
