Below is a quick history of the car and the current modification list. I still plan to provide more details about the mods, but that will come at a later time when I can get that all typed up. Thanks to Michael (DerFahrer) for the proof reading and feedback on the write-up.
A 1990 Legacy’s Journey from

History
This Legacy started life as a naturally-aspirated, front-wheel-drive, automatic 1990 Legacy L. It originally belonged to my grandfather, and I inherited it in 1995 when he passed away. It had 80,000 miles on it then and has taken me through high school, college, nine cross-country trips, and a transformation from something ordinary to what you see here today.
At currently over 196,000 miles on the chassis, this Legacy has seen its share of miles, modifications, and adventures. Almost every component other than the main chassis has been modified, replaced, or upgraded. It has undergone two major conversions/swaps in its lifetime, including a swap to all-wheel-drive and a manual transmission in 2004 and a swap to a rebuilt EJ22T engine from a Legacy Turbo in 2005. The engine has been rebuilt a second time with forged internals to compliment the larger turbocharger, custom air-to-water intercooler setup, and fully programmable standalone engine management system. Current horsepower and torque levels are approximately equivalent to a stock STi. In 2013 I completd an STi 6spd transmission swap to replace the Turbo Legacy 5spd I previously swapped in.
This car's transformation has been an amazing journey, and I hope you enjoy seeing it as much as I've enjoyed building it.
I recently had the engine tuned and it made 255 hp & 306 ft-lbs at the wheels. Dyno comparisons & plots can be found here in my build thread.
