Major Parts

  • Factory Five 818C Kit

    The coupe model of Factory Five Racing's three 818 kit car options.

  • Subaru EJ207 Turbocharged 4 Cylinder Engine

    Sourced from a JDM Subaru WRX STI, this engine is a high-revving variant of the 2.0L turbocharged EJ series.

  • Vintage Air Mini Gen II AC System

    Some people might not consider AC to be a major part of a kit car build, but it might be my personal favorite.
