Second Hand Alfa Romeo Spider Camshaft

The Alfa Romeo Spider ran from 1994 to 2005 in its 916-series generation, and camshaft compatibility within that run depends almost entirely on engine code rather than the year alone — so a camshaft from a 1994 car will not automatically suit a 2002 car even if both carry the same badge. The 916 Spider was offered with several engines including the 2.0 Twin Spark, 3.0 V6, and later the 3.2 V6, and each has its own camshaft specification. Always cross-reference using the engine code from your V5 or a VIN check, and confirm the specific part number with the breaker before buying.

No — the 3.0 V6 and 3.2 V6 are different engine families with different camshaft profiles, and the parts are not interchangeable despite both being V6 petrol units. The 3.2 V6 (engine code AR32401) was introduced in the facelift-era cars around 2003 and has a distinct internal specification from the earlier 3.0 (AR16102). Supply your engine code to the breaker so they can match the camshaft exactly to your unit.

Yes, it matters enormously — the 2.0 Twin Spark (engine codes in the AR32310 family) uses an inline four-cylinder with twin camshafts, while the V6 engines use a completely different block and head arrangement with their own camshafts. These parts are not interchangeable across fuel delivery or engine architecture, so you must know which engine you have before searching. The engine code on your V5 logbook or from a VIN check is the single most reliable detail to give a breaker.

Trim level makes no difference to camshaft fitment on the 916 Spider — the Lusso and other trim variants fitted to the same engine use identical camshafts, as trim relates to interior specification and equipment rather than mechanical components. What determines the correct camshaft is the engine code, not the badge or equipment level on the car. Focus on confirming the engine code with the breaker rather than worrying about trim.

The 916 Spider ran throughout this period, but 2003 sits close to the late-production updates when the 3.2 V6 was introduced, so whether a 2003 camshaft fits a 1998 car depends entirely on whether both cars share the same engine code. If both are, say, 2.0 Twin Spark with matching engine codes, there may be a case for compatibility, but ancillary and specification changes mid-production mean you should confirm the exact part against your registration with the breaker rather than assuming year-range overlap guarantees a match. The engine code is your starting point.

The 916 Spider and 916 GTV shared their engines and running gear, so a camshaft from a GTV with the same engine code as your Spider should in principle be the same part — engine codes are what define the camshaft specification, not the body style. That said, always give the breaker both engine codes and ask them to verify the part numbers match before purchasing, as there could be detail differences on ancillary components that are not immediately obvious.
