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?

they didnt use it because the current gearbox couldnt handle the torque

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

wouldnt it be easier just to pull the bits from a saab?

Using saab bits was what i was thinking.

What power and torque are you hoping to get that you want a bi-turbo? A single turbo is giving me 228 wheel horse power on standard injectors.
