I have a set of stock cam cores for sale. you can use them to get the Rallitek ones so you don't have to worry about down time waiting for yours to arrive. The core is $400, but I will sell these for $200. in addition to no down time, you save $200. win-win. In addition to this, you can sell your stock ones when they are out.
they work on 06-09 2.5i impreza/legacy/forester.
