Hi all,
What started out for me as a downgrade from my 2012 STI hatch is now becoming something more that I didn't expect or plan. Ive always had a soft spot for the Liberty especially the wagons since my very first Subaru an RS wags back in the day. When i found an 08 GT Liberty wagon, tuned by STI version with the 6MT and only 110,000ks I thought it would be perfect. 2 months after owning it I sent it in for its major service only to find out it had a blown head gasket. ...Id been stitched up
SO what initially was just going to be a family car that my wife will mainly drive is now turning into a bit of a build I've been dreaming about doing for many years. The goal is to have a standard looking car, with serious power when needed and reliable drivability as a daily family car. So instead of just doing the heads and making do, I've lost my mind a little and blown my budget out completely.
I will update this thread periodically as it progresses and include photos when I can. But I will make a start.

Tune
I have had a road tune with Matt but only to check things were safe during the run in. Was first dynotuned on 31st August by Matt in Coffs Harbour. Achieved 227KW and over 900Nm of torque at 18.5psi. Will post chart when it turns up, MM still has this.
UPDATE: Road tuned with MM (May 26 2016) and it is completely done for now. It is producing more power now since the dyno with this turbo and I have eliminated the boost creep we experienced with the Blouch unit. The 8cm hot side on the current setup seems to be working well with the 2.5l. A max boost for now of only 19psi and plenty of fuel up top and it's just keeps going. Absolutely stoked with the new 20G.
