To start this off, this is my very first import car that I have ever owned. My last car was a 2000 Trans AM. I recently got stationed in Tokyo, Japan and will be here for the next 3 years. I've been doing (trying) tons of research on this car. Not sure where to start, everything I find usually has to deal with the car being a track car. This car WILL NEVER see a day at the track. My main goal is 330-350wkw.
I know the 100,000km maintance just around the corner(99,000km currently). It's currently my DD but will not be in about 3 years when I get orders back to the states. What should I have put in when I have that maintenance done(after market)? I guess the main question is, Where do I start? If someone could easily link me to a build or help me figure out what would get me to that point. (I have included a picture of my car).
