InsigniaEngines for Sale —Used & Reconditioned

The Insignia's core engine range includes the A14NET 1.4 Turbo petrol and B20DTH 2.0 CDTI diesel. A conditional 1.6 CDTI covers late Mk I diesels. A significant number of additional engine families (2.0 Turbo petrol, 2.8 V6, 1.8 petrol, earlier 2.0 CDTI variants) were omitted from the BRF and await escalation. Across the two generations, the Insignia used a broad mix of GM Ecotec, SIDI, and CDTI families, with outputs from 110 PS to 325 PS.

Check the V5C registration document for the engine number; the engine code is also stamped on the engine block plate. Insignia engine codes include A14NET, B20DTH, A20DTH, A20DTE, A20DTR, A20NHT, A28NET, A18XER, A16XHT, B16DTH, and others. For transition years between Mk I and Mk II, confirming the chassis code (G09 vs Z18) alongside the engine code ensures correct fitment.

For Insignia's A14NET 1.4 Turbo, timing chain stretch is a known issue — reconditioned units with updated chains may offer better reliability. For B20DTH 2.0 CDTI, used engines are widely available and represent the most cost‑effective option. For other Insignia engine families, used units are the default choice due to high availability across the dismantling trade.
