I'm a new proud owner of a 2002 subbie and I just had a couple of questions concerning the engine and turbo. First, I've noticed that my boost gauge only hits about .07 mPa. Is that the max for a stock turbo? I've only filled the car up once and that was with the 89 fuel, I now know that I should use premium only. Will that make much of a difference? I am also concerned about how fast the engine heats up. I'll only be driving it for about a mile or so and by the time I shut it off, the heat coming off the engine is incredible. My oil and coolant levels are fine, is it just the turbo that heats up quickly?
