This is my 1986 Toyota Corolla GT-S - the Superhachi.

My friends and I have done all of the work on this car in my garage. It took me two and half years' worth of weekends, but it is finally near completion. Many more pictures coming soon.
Below is a list of the modifications that I have done to the car. Check out the theory pages to find out why I did some of these things.

What the heck is a hachi?

The car obviously hasn't been painted yet. I'm leaning toward black because that's the color it came from the factory, but right now I don't mind it in primer - it's not a show car. Primer looks mean; it says "My owner spent too much money on performance to be able to afford cosmetic crap." And that's the truth!

Here she is. The first one shows both of my cars.
