Chris’ 1986 Honda Accord Hatchback

The Story:

I have been working on this car for 10 years now. What started out as a project to build a ‘low boost’ accord running a few pounds of boost has eventually escalated into a decade long project. The car looks a lot different than it did when I first took ownership.

The history of this accord will be retold in blog posts, but this page will be my attempt at a ‘current’ snapshot of the cars status. As I complete the car, this page will be updated.

A lot of time, effort, and money has been spent on this project. Many parts have been purchased, removed, swapped out. What you will see here is a list of the parts on the car as it sits now. Although I hope to eventually chronicle all of the phases that the accord has gone through over the years.
