i need some pics of the turbine on a standard ERST,

also am i right in thinkings the turbine can move up and down but not in and out? how much movement are you allowed in and out?

what needs to be drained so i can get the turbo off? i think its the coolant and the oil?

also whats all the differences between turbos? i did a search for T3 turbo on ebay but it came up with saff's and all different housings and numbers, what do they all mean?

thanks people
