    Default twin turbo 1.9 cdti vec

    Hi guys. Just wondered if anyone had made thei cdti into a twin turbo diesel like in the saab? Would it take much work to put it on a Vectra diesel?

    The best way to twin a Vectra would be to fit a second large turbo in series down behind the engine. It could involve an electric oil pump and a seperate oil tank, exhaust modifications and intake pipework. I'd use a pressure actuated setup to control it to a set max pressre of something like 1 bar.

    The gearbox is rated for 300lbft and the torque can be limited to that easily enough as they have done with other engines, including the new bi-turbo Astra and Insignia

    They use the ECU to control the turbos and are not VNT turbos I believe, so it would require alot more work, including mapping if the ECU was capable of controlling it.
