2014 WRX in for a complete engine rebuild, sporting Manley forged pistons and H beam Rods. this is ready to roll. Wrapped up this 2016 Forrester in for a head gasket job. Been a silver Subaru kind of week. Now we need to get this 2013 Forrester wrapped up that came in for an engine replacement. Then we will be back to our regular schedule of Blue Subarus. Lol

Finally!!! here is a project we just wrapped up that took way too long on this 1974 Delta 88, ready for paint and full interior but we were missing every nut and bolt on this thing. Today it’s ready to to go on to the next phase. Completely custom twin turbo kit and complete build. It’s a wonder feeling when you finally wrap up a project that you know took entirely way to long!!! But she sounds good and ready to make boost!!
