    Turbos are cheap enough. Especially with a TMIC car, a turbo blanket is worth any reliability issues you may encounter. With a FMIC car, it's a bit less of an issue, but I'd have no hesitation putting one on my car...

    I've never heard of reliability concerns with using a turbo blanket. I would think if anything it would improve reliability because it will extend the cooling period for the turbo. Quick, drastic temperature fluctuations are detrimental to turbo life (and pretty much any material).
    ^That. Besides, I have no way of directly measuring underhood temps.
