Hi folks,
I've been reading about turbos blowing up, and I'm trying to get more details:
1) How do you tell if a turbo is blown? What kind of noise is there? Or is it just no power, with no boost showing on the boost gauge?
2) If you don't use the car "in boost" often (ie. keep below 3-4000 rpm, hardly anything showing on the boost gauge) does that help the turbos' longevity? (My understanding is that they spin regardless whether you're "in boost" or not, right?)
3) How many k's are turbos expected to last, assuming I use factory boost settings, and change oil regularly and cool it down properly after hard driving?
4) How do you tell a turbo is on the way out, apart from actually inspecting it physically? Does a worn turbo smoke? (why?) Does it make some kind of noise? Will it just blow up without warning?
5) Is the car drivable when turbos are blown? Will I risk further damage if I drive it? As I understand, most of the Japanese R33 turbos were ceramic, and someone told me that this means they could shatter and be sucked into the engine causing major damage... true or false? If true, why weren't the stainless steel ones that were made for UK used instead? Cost savings?
Thanks in advance for imparting your experienced wisdom.
