In 2007 I was lucky to stumble into buying what I now appreciate as a rare find; I own a 2004 Lexus IS300, manual, Sport Design, in thundercloud metallic (TCM). Wikipedia publishes that only 20,000 2004 IS300s were produced, most of which had automatic transmissions. The manual transmission and the Sport Design package add to the scarcity, leading me to estimate that there are fewer than 1,000 of these in North America.
I purchased this vehicle with the intentions of applying my engineering and mechanical aptitudes toward auto-repair and modification. The IS300 shares a heritage with the Toyota Supra and the AE86 and serves as an excellent platform as a performance vehicle (ref; http://www.autoanalyser.com/racing/).
Primarily as a learning experience, I’ve set out to upgrade the performance of this IS300 while maintaining a reliable, balanced, clean, and comfortable vehicle. These pages will document the learning and progress of this journey, providing both a record of development and hopefully some material that others can find useful.
