I am currently building up my 92 Jetta with a 1.6L TD engine in it up for the summer. Right now I have both a T03 and a K24 whose turbines both spin about the same sitting in my garage and I need to pick one to use on the engine. The K24 was sitting in the car and came out last night when I pulled the head and I grabbed the T03 out of a junkyard about 6 months ago. Which one would be better to use and would it be smart to rebuild it before putting it back in? If so where should I go to get a kit.
