Replying to: robertsmx (Nov 06, 2007 9:39 am) A high-pressure turbo and an intercooler may be a complex system, but a tried and true system as SAAB initially used this system in the early '80s SAAB 900 Turbo. It's a very reliable design, and a high-pressure turbo will easily reach 150K miles without a failure if one changes oil regularly and uses a quality oil in the first place - and, not shut the engine down immediately after high-speed operation, so that you don't cook the oil out of the turbo's bearings. Diesels, especially those used in over the road trucks, have been using this design for many years, and it's truly a reliable solution. I think some are just concerned with the long-term reliability question of the VCM system.

Replying to: colloquor (Nov 07, 2007 5:36 am) Like every technology, it has evolved over (now) two decades, with VCM feature added five years ago. Diesels aren't the same old thing either. A lot of complexity has been added besides turbo/intercooler. You can't compare today's diesel to diesels from two decades ago, could you? One could even argue against the new catalytic converter, the new casting techniques, the common rail design and so on. But if we were to be wary of every new development, we might as well stick with a Model-T. I'm sure it didn't have the engine mounted even on a subframe, much less an active control/hydraulic mount.
