You blew your turbo bearings plane and simple. what had happend was your were probably racing around in it on a Stock pressuer relief valve (blow-off valve in street terms) and your pressuer backed up into the turbo, therefore sending the trubo's bearings for a spin the wrong way, probably nocked a couple in to the fan of the turbo and messed some stuff up. Auto salvage yard. you have the 2.0 H4 which is a very common subaru engine, and just pull apart a legacy touring or outback edition and grab all the turbo essentials. also to prevent this from happening, buy a cheap aftermarket blow off vavle, you'll hear a small wistle when you shift gears (if its a standard/manual transmission) but if not then you won't hear a thing. but its normal for the wistle to happen, that is letting you know your blow off valve is allowing any backed up pressure to escape. And one last thing, AUTO START is a big help with turbo engines, you can park it, take the key out, get out of the car and the car will remain running for 10-15 minutes to allow any back pressure from the turbo to work it self out of the engine. Trust me i have a nissan 240sx with a hevily modified engine, and until someone pointed this out, i blew and bought 4 turbo's

Turbo maintenance


If you let the car idle when you stop driving it gives the car time to recirulate fresh oil through turbo bearing , since the turbo gets extremely hot from the exhaust side (and spins at very high speeds) you really should also run full synthetic oil on turbo cars to extend turbo life.regular motor oil tends to burn and carbon up in turbo bearing and causes premature turbo failure .
