IMS failure was most prevalent in pre-2000 Porsches--not only Boxsters. The 2005 redesign also took care of that issue for the most part. It's a rare problem, but because it essentially ruins the car it gets a lot of attention.

At idle there's not really enough exhaust pressure to bring the turbine up to any meaningful speed though.

The problem with older turbos as I've experienced it wasn't so much a lack of start-up lube, it was oil coking from heat soak when people didn't let the car cool down for a minute or so after driving. The oil would coke and you'd get crystallized particles in the bearing, which scored the shaft and seals causing problems or blocked the oil inlet passages.

Modern turbos have cooling jackets around the bearing and either use electric pumps or thermosiphon to keep coolant circulating after the engine shuts off. This prevents the coking issue and is really what allows modern turbos to last longer.

LN engineering makes a 600 dollar kit that replaced the bearing with a ceramic one. For a RWD 911 it runs about a grand to put in.

There's been like 1 failure reported with the 05+ IM bearing on 996/997 cars.

Man. A quick search in my area has 05-06 non-S models running in the upper 20s unless they have 70K+ miles. Sad times.

You have to be willing to travel if you want one. They're overpriced in the north and underpriced in the south.

I searched within 100 miles of Atlanta, GA. Nothing caught my eye from the listings I saw.
