The project
A two-year owner build that needed the last, hardest ten percent.
Marcus has known Diego through the Subaru community for about a decade. He rebuilt the engine himself with his girlfriend over roughly two years, checking every part for dirt, hair and metal shavings at every step. The result was a clean, knock-free engine. He brought it to Mico Motorsports for a flex fuel system and the finishing work.
“When you have as much experience as I do, you know all the ways you can creatively route different wires and hoses to make the engine bay look as clean as possible.”Diego Rodriguez · Mico Motorsports

What we did
Our work
- Implemented the COBB flex fuel system
- Fabricated a custom bracket to relocate the fuel filter and make better use of the bay
- Re-routed hoses and wiring for a cleaner engine bay
- Moved components to mitigate heat soak
- Fixed muffler-tip contact with the rear bumper
- Recommended bringing the removed A/C system back
