A customer came to us recently with his 2006 Subaru Outback XT 5EAT . Most of the time when we see OBXT’s it’s just for maintenance or repairs, but this gentleman had something else in mind. While keeping the car completely stock in appearance AND sound, he wanted to be able to humble muscle cars on the freeway of Northern California. He also stipulated that the response characteristic of the turbo chosen had to mimic those of the OEM turbocharger, while passing the tailpipe sniffer come smog inspection time. With this unusual and challenging set of requirements we set forth building him a car that would satisfy and even exceed his expectations.

The poor stock torque converter is a little overwhelmed in this application leading to some irregular power transfer at high rpms but will do till it comes time for a fully build transmission.
It does not get much more stealth than this. Watch out streets of NorCal!

Allow us to reintroduce ourselves to the Street Class record for Redline Time Attack.
Here are a couple laps around Autoclub Speedway in Fontana, CA in the Yimi Sport Tuning / Jager Racing Redline Time Attack Street Class 06 STi. The 1:47.365 on the second lap in the video captured the Street Class overall win and put us within a half second of the street tire TA record at ACS. We’ll be back in a couple months in cooler weather in search of the record.

Turn the sound up and listen to those tires complain as Mark punishes his car in summer weather at Buttonwillow Raceway.
This customer is using a carbon fiber hood and an upgraded top mount. Now that intercooler will get proper airflow.
