06 STi – HTA GT3586R – dyno tune
This was a complete build from the ground up, done by Jan and Angel. The car’s previous setup had a Blouch Dominator 1.0 turbo that put down 330whp on the heartbreaker dyno, resulting in a 1/4 mile pass of 11.8 seconds. Of course, the owner still wanted more.
This time around, a custom rotated-mount setup with a large turbo was installed along with a slew of supporting upgrades. The original block was bored over and rebuilt with Eagle rods, CP pistons, ACL race bearings, ARP head studs, and Cometic head gaskets. Killer B Motorsport’s reinforced oil pickup does its part to keep everything properly lubricated.
The basic parts:
- GT3586R turbo with HTA billet compressor wheel and Tial turbine housing
- AEM EMS
- 1200cc injectors
- custom fuel system
- Ported heads
- Brian Crower stage 2 cams
- TurboXS FMIC with custom piping
- GT-Spec header
- TiAL 44mm wastegate
This resulted in a set of strong, but reliable tunes on pump and race gas.
The results:
Pump gas: 392.6 hp @ 6750rpm and 335.5 ft-lbs @ 5750rpm
Race gas: 445.5 hp @ 6750rpm and 377.5 ft-lbs @ 5500rpm

Now this right here… This is how it’s done! *When* I build another Subaru, the spec sheet will look very similar to this.
Nice work, guys!
