Importnut’s ’94 Civic Si Hatch

Here is my ’94 Civic Hatchback.  I’ve owned this car since October of 2002.  I bought it shortly after I totaled my ’95 Civic Coupe.  I’ve managed to keep a few bits and pieces of that  first Civic which I bought new in 1995.  My civic went from daily driver to a dedicated project car/autocrosser in 2007 after a catastrophic engine failure.

As the years go by, I make an attempt to strategically plan the work I do to try and make cost effective improvements as they relate to autocrossing.  As I learn more about suspension tuning, and tire tech, I feel as if I can hone in on the best modifications for the money spent.

Building my Civic into a Street Modified FWD nationals level contender would be a blast. However, I only run at the local level and having a 300+ hp civic running 275 35 15 Hoosiers up front is overkill.  I’ve been successful running my mild setup on street tires and I’m satisfied with the incremental improvements I’ve made over the years.
