I saw that video earlier in the morning. Absolutely awesome LGT. I never knew that there was ever a stock TT Subaru. I wasn't a huge fan of the "stance" setup, but it's definitely a unique looker.
Ej20k out of the early 90's legacy. Wasn't a very great motor and the swap can be had for around a $1000. Unique non the less.
It's actually a 20h, the 20k is a single turbo sti engine. Subaru also made the 20r, 206 and 208 which were in the later model legacies I believe, also twin turbo.
My first Subaru was a 1996 Legacy GT. I loved 90% of it. It was my first and last Automatic. Drive has done a few videos of custom builds with Subarus. It's nice see they're noticing people's efforts outside of Resto-Mods.
