IAG Sponsored 2007 Subaru STI Time Attack Build

Features: IAG Built Engine, IAG Rotated Turbo System, V-Mount, Roll Cage

About: This project started as a 2002 WRX shell we donated to the build a few years ago. After the shell was sand blasted IAG was contracted to prepare the shell for NASA sanctioned time attack series and possibly endurance racing. The shell's frame was measured and the frame was pulled and repaired in a few places. The front clip received a 2006-07 Impreza STI face-lift. The chassis was completely stitch welded and the front and rear fender areas were tubbed. A NASCAR bar roll cage was added based on rule specifications and the clients desires. Rounding out this project is our V-Band Rotated Turbo System with V-Mount intercooler and our Stage 2 Short block. This ground up build has many unique parts and will be hitting the track soon.
