Built forboost.
Engine builds, custom fabrication and COBB tuning for Subarus that are driven hard. One specialist shop, every model and year.
About Mico Motorsports
Not a general repair shop. A Subaru specialist, from empty case halves to a finished engine bay, and everything that has to work around it.
Mico Motorsports is Diego Rodriguez’s shop: more than a decade in the Subaru scene, building engines, fabricating what doesn’t exist yet and tuning with COBB. Bring your own parts or have us source them. Either way, the work is done to the same standard.
What we do
Engine Building
Complete Subaru builds, from bare case halves to a running engine bay.
Performance Upgrades
Turbo, fuel and supporting mods specified as one system, not a parts pile.
Custom Fabrication
Brackets, relocations and one-off parts made in-house when nothing off the shelf fits.
Race Preparation
Reliability-first preparation for cars that see the track.
COBB Tuning
Authorized COBB dealer. Parts, flex fuel and calibration support.
Accessport Services
Accessport supply, setup and data logging.
Subaru Service
Maintenance and repair on every Subaru model and year.
Anatomy ofa build
The same process on every engine that leaves the shop. Scroll through how a Mico build comes together.
Teardown & inspection
Every build starts with a full teardown. Parts are cleaned and inspected before anything is decided. What the engine needs comes from evidence, not a catalog.
Specification
Power target, fuel, turbo and how the car is driven set the parts list. Supply your own components or have us source them, OEM or aftermarket.
Assembly
Short block to long block, assembled by hand on the stand. Bearings, rods, pistons, valvetrain: clean, measured and torqued.
Install & plumbing
The engine goes in with the same attention: hose and wire routing planned for heat and serviceability, custom brackets where needed.
Tune & verify
Calibration with COBB tools and data logs before the car goes home. Built to be driven hard, not just to make one number.
From the shop
Marcus’ 2005 STI
An owner-built EJ25 on a rotated GTX3576R Gen II. We implemented the COBB flex fuel system, fabricated a fuel filter relocation bracket and re-routed the bay for heat and clean lines.
- Turbo
- Garrett GTX3576R Gen II · ETS rotated kit
- Internals
- Manley Turbo Tuff rods & 99.75 mm pistons
- Fuel
- Injector Dynamics 2000cc · COBB flex fuel
Made herewhen itdoesn’t exist.
Diego taught himself to weld because the brackets he needed didn’t exist. Years later, custom fabrication is a core part of the shop, and the same thinking goes into preparing cars for the track.
- Custom brackets and component relocations
- Hose and wire routing for heat and serviceability
- Track-day and race preparation, reliability first
Tuned withthe right tools.
