Part I: Overview
This is a thread about our shop project car, which is a 2000 Impreza. The chassis code for the 2000 Impreza is "GC," and that's how we usually refer to the car, especially since we need to distinguish it from the later "GD" chassis. (More on the GD later.)
Some of the general history behind how we got into this project is covered in a two-part SubieSport article that should appear sometime soon, and I don't want to duplicate too much content, so I'll leave some of the more general stuff for that. Here I'm going to talk in some depth about what it took to accomplish this build, what I might do differently, and suggestions I'd have for others looking to maybe take on a project like this themselves.
Our project's humble beginnings
Our goal in building the car was to make something relatively cheap that the track-driving members of our shop staff could use at the road course, without risking our more-expensive street cars. We settled on a GC Impreza because they are cheap, and any/all of the recent-model Subaru parts will fit on or in them. We started out planning to keep the naturally-aspirated 2.5 liter engine from the stock car, but one thing led to another, and soon we had an entire swap project on our hands. Specifically, we decided to swap the entire mechanical and electrical assembly from a 2004 STi into the 2000 Impreza.
