So my brother is getting back from deployment next month and he wants to start in right away on his gtp. Right now he's got a set of headers (I think they're the Speed Daddy ones but I'm not sure), colder plugs and t stat and he had a buddy of his tune it up. He said he's interested in going turbo so I've been looking up some info for him.
It looks like right now the z3 kit is probably right for him. I have a couple concerns though. I know the tranny on these cars are weak and I assume we'll have to upgrade once the turbo kit is on, but is there any other mods that need to be done engine wise? Also the car is his daily driver, how are turbo on these cars (z3 setups specifically) as far as reliability goes? Sorry if these questions are rehashs.
