Hi. I have an 02 Wrx, BONE STOCK (except wheels)with 180k. My problem is a recent loss of power while boosting. I had noticed the feel of the car has become sort of, weak compared to the norm. I have a boost gauge and it seems that the gauge is showing adequate boost in the system. Could that be a lie? Its a simple cheap looking gauge that is in the BAR reading. Im making about 1.2 to 1.5 BAR at full boost. It kinda goes in surges sometimes.
Either way, the other day my wife said that the car was smoking at the light before our house and when she had pulled in there was no sign of any issues. Fluid levels/ leaks etc.. were all good or not an issue. So 2 or 3 days later I was driving and the car began to smoke at a stop light. I jumped to a parking lot and popped the hood to see a light amount of smoke coming from the turbo area. Could not pin point it cause of the heat shield blocking my view. It only lasted maybe 45 seconds after I had pulled into the parking lot. I couldnt say whether or not it was blue or white smoke. (I have done some homework here on these issues..) I remember it was lighter in color light cigarettes and light in mass/ almost whispy..
So, A day later (yesterday) I noticed the car was gutless feeling. To me it was like the boost was only half-working power wise. I have checked fluids and the oild was surprisingly on the low side . I put in about 3/4 of a quart to bring her back to good.. The only thing that is an influence here would be that i have just put new tires on. We were on the way to the shop when the smoke reared its face to me.. But I don't believe that 4 new tires would make a car feel like its losing power. If anyone has any ideas or first off to do lists... that would be much appreciated. Thanks in advance!
PS: If this is a turbo going bad, A suggestion turbo and where to buy would be MUCH APPRECIATED! I dont mind upgrading to a better turbo but would like it to be compatible with the stock system or as minimal changes to the car as possible.
