TOOLS NEEDED
MATERIALS NEEDED
Use the stock O2 housing to fabricate a jig. Start by drilling two holes in the base for the stock exhaust studs. Put a nut on one or both of the studs to secure the O2 housing to the base.
Next use a piece of wood 5 1/4" wide. Cut one end at a 20 degree angle. Then cut a notch in the bottom of this piece to go around the stock O2 housing.
Hold this piece of wood flush with the face of the stock O2 housing and mark around the flange.
Use the turbo side O2 flange (which can be purchased from Road Race Engineering) to mark and drill the holes for the flange.
Instead of permanently attaching the two pieces together, I used some thin sheet metal and made a bracket for both sides of the vertical piece. Mark on the base where the vertical piece will go. Start with a 1 1/2" - 2" wide piece of metal and fold it at 90 degrees. Drill 2-3 holes in one side for a few screws and attach it to the base. Bend the edges of the bracket around the wood to make a track for the board to slide in and out. Drive a finishing nail at the bottom edge of the vertical board to keep it from sliding forward.
Almost finished - cut a notch in the right side of the base about 3" wide, close to the bottom of the vertical board. This will allow you to mark bent tubing to the length needed.
