How many have you have had issues from a turbo/supercharger?

Zatanna Z

Thanks to you all for the informative responses back and the advice given. It seems to me that there is too much maintenance work involved with a turbo and it could cost too much money in the long run for me right now. And I don't think I have any reliable shops I could trust that are putting turbos in Z's all the time and tuning them as well. I want to do some mods still though so I'm thinking just some simple things such as a Stillen dual intake along with an exhaust but unsure of brand for exhaust maybe stillen or fast intentions?
