Quite a lot of cars have the turbo on the back of the engine and have no problem with it (e.g. Volvo S40 2.0T / T4). Turbos are mostly water cooled these days and can have synthetic oils. Cars have better heat shielding too... Having the exhaust manifold on the back and the intake manifold on the front means that the engine can be farther back, which improves the weight distribution of the car (have a look at the shape of the engine back, particularly the "transmission tunnel" where the exhaust / turbo live). -- James Smith "KeithG" <noonenopsamspring.com> wrote in message news:auign1$rjb$1nopsam.atl.mindspring.net... > It is a GM Global 4 engine and has a lot of features of the Saab engine. > The version in the Saab is significantly different than the 2.2L that > finds its way into other GM cars.
