have a look. a dual round snail-shell piece of plumbing attached to your exhaust and inlet systems. several inches in dia, very obvious. Alternatively, does your motor switch off immediately when hot, or does it cool down via timer and then switch off. If latter , it has a turbo, or it should, unless it's been removed. Whine and blow off noises also confirm turbo at speed and back-off. Nothing like ignorance to wreck a good car, I say.
