Well.. I'm far from an expert... this is my first WRX... and everything I've done, was for the first time.... so it's a constant learning process.
I'm going to take pics.... but it looks like someone has already done a good turbo swap instructional post. In fact, I'm going to use this as a guide on Saturday.
Granted... this guy has a FMIC, but the turbo removal and install should be the same.
