A little background. My previous vehicle was a '98 Legacy GT Limited AT that I absolutely loved, but it fell a little bit short on the power potential without big money. In the fall of 2008, It was time for an upgrade, so there were a few vehicles I considered. Since my replacement would remain my daily driver, certain criteria had to be met.

Perform well in all seasons
Comfortably transport my family
Wife approved attractive design
Rather uncommon
Available manual transmission
Good power out of the box
Good upgrade and aftermarket potential

When weighing all the criteria, a few vehicles came to mind. Those include the G35 sedan (expensive at the time with AWD), Audi S4 (same), Mazdaspeed6 (couldn't even find one to test drive), and obviously the Legacy GT. Needless to say, the Legacy GT was the best candidate especially since I liked my '98, figured an updated version of it I'll like even better.

I looked at a few different 4th gen Legacy GTs before purchasing mine in September 2008. I chose this one for all the usual reasons; best price per mileage, color, options, etc. It was bone stock when I bought it, but that didn't last long. Purchased and Accessport and flashed to a stg1 map. Shortly after that, I got a downpipe and catless uppipe and flashed to a stg2 map. As time went on, more and more parts got added and it would take me forever to chronicle the piece by piece installation so rather, several years later, here's what's been done.Yes, at the time of this posting I've been sitting on this turbo for about 2 and a half years. It was the last of Edmundu's huge part out thread so I got it. After we made the deal, he noticed that there was a crack in the turbine housing. He had a new and upgraded turbine housing shipped to me and I had that ported and coated. For the next year, I gathered parts for the upgrade. Here is my current setup.

As the car sits, all parts above have been installed and the car is running, however not fully tuned. An updated base map needs to be flashed to the ecu before we go any further. I can tell you that at only 14psi, this thing pulls hard and its street manners are actually more mild than the stock vf40. Not nearly as punchy with smooth power delivery throughout. At least that's what the butt dyno tells me.

This thread will be updated as the car gets further tuned. I'll be posting logs as they come available as well as dyno graphs. This weekend, we will be working on completing a 93 octane winter tune. Springtime will add an E85 tune to the equation. This was being tuned by a tuner, but I've since taken over the workload assisted by member qikslvr. Qikslvr has helped me immensely get to this point so I'd like to thank him publicly for his efforts.

Stay tuned (bad pun)
