Insignia VXR/Vectra 2.8t Same engine?

[Vetox]

Does anyone know if the 2.8T in the insignia is the same as the vectra/signum?

Does anyone know if the 3.2 Gearbox is similar/same as 2.8 box? (between facelift vectra's/signums)

Thanks in advance

The Vectra 2.8 engine is a Z28NET/L/H Variant.
The insignia uses a simular version, A28NET.

The 3.2 Gearbox is a 5 speed and the 2.8 a 6 speed
