9-5 is available with 4 engines, B205E, B235E and B235R and a V6 engine which I don't know the name of. The engines give 150 hp, 185 hp, 250 hp and 200 hp (I don't think the 150 hp B205E is avaliable in the US).

Three diffrent turbochargers are used, B205E and B235E uses a Garrett GT1752 and the V6 uses a GT1549 (integrated with manifold) and the B235R uses a MHI TD04HL-15T-5.

Boost pressure is controlled by the Trionic 7 engine control unit and the pressure varies. The control system is built so that when the driver gives gas he is "requesting" a amount of torque on a given torque curve which the engine then will deliver. To deliver this torque the T7 system will open the throttle, adjust the boost (and many things more) so that the torque given by the engine will be the same as the driver requested.

But there will also be an upper boost limit, for B235R it's 1.5 bar and for B205E and B235E I think it's around 0.5 bar.
