Positives, smaller engine needed, higher power output when turbo kicks in. When turbo kicks in, fuel consumption goes up. Without turbo, fuel consumption is much better. Disadvantages: lag in turbo power boost, since it is run from the exhaust gasses (there are mechanisms to make this somewhat better). Mechanical complexity, it's another piece of equipment. Car will need more frequent oil changes, but that's only good maintenance anyway. (not more frequent than 3000 miles). Turbo has a limited lifetime, and will eventually require replacement. (yet another thing to break). >Since Saab seems to be the only manufacturer with turbos, the question >is why? They're not. Mercedes has them, Subaru has had them, Volkswagen (I think) might have had them. Mitsubishi, Ford, Mazda have had them (Ford Probe GT, 1989 to about 1993 or so, GT model). Mitsubishi Eclipse, mostly any GX, I think. Saab is the only manufacturer that makes the turbo standard on all models, iirc. Two varieties, depending on how much boost (additional air pressure) you have. LPT and HPT. LPT generally (2000 9-5, for example) does not have a turbo pressure gauge. engine is a 2.3t (small t), HPT has more boost, higher horsepower, and is a 2.3 T. Higher boost generally means more engine power. (note: had an 89 probe GT, loved the car. Had mitsubishi 98 eclipse without turbo... was really dead.) Father had 200D (diesel, turbo) Mercedes... had very bad turbo lag, (dead to 2500 rpm, then zoom after it), have 2000 9-5... much nicer. Harvey > >Thanks > >Peter
