I fail to see how Mr LOL's vectra has anything to do with this? This is the Insignia not a Vectra and the Vectra was sports remapped (although I honestly don't know if the engine and drivetrain have just been carried over or not).
it has
it uses the same 2.8 block and F40 gearbox that is only rated to 300 lb/ft of constant torque.
They have fitted a bigger turbo, improved water radiator and intercooler design, and changes a few bits and pieces but its broadly the same engine.
