I was talking to XS Engineering at SEMA and I asked them when the GTS turbo kit was coming out. They told me that it should be out between January- February 2003 and that they were going to start taking pre-orders pretty soon, I think they told me after SEMA. They said that the reason that it was taking long was that they were waiting for some ECU's to come in.
