I have NO experience with turbos.
In fact, the only turbo I've ever driven was a Saab 900 back in the early '90s. While fun-to-drive, especially up in the mountains of Colorado where I was passing normally-aspirated cars left and right, the replacement of its turbo was ridonkulous.....like $1200 iirc....JUST FOR THE PART !!
I'm wondering if the today's turbos are better than the ones back then. With proper care, how long do I expect one to last ??
I'm thinking also that today's synthetic oils are WAY better equipped to handle the stress and extreme heat of such devices.
