Josh's 2015 STI 800hp Build - Stage 17
Josh brought us his very low mileage 2015 Subaru STI back in January of 2016 for basic bolt ons. We installed our Stage 3 package which you can read about HERE That setup made 400hp on 93 octane and 436 on E85 using the Johnson Tuning flex fuel kit. This was accomplished on the stock engine. Our tuner Corbin has tuned many of these setups on the stock engine and is able to keep them reliable and fun! Josh drove this setup for the whole summer traveling from show to show without any issues. Josh came to us in the fall looking for more power, specifically he wanted to break the 800hp barrier. He also wanted some custom parts to keep his build unique. We came up with a plan and started ordering parts. IAG Performance never lets us down, so we spoke to them about our goals and settled on a Stage 3 Tuff engine package with the following upgrades.
- Manley Turbo Tuff Rods and Pistons
- Stage 5 CNC Heads
- Kelford 220C camshafts
- ACL high volume oil pump
- ARP 2000 1/2" head studs
- Manley valves
