  install the bolts that connect the turbo to
  the header.
  NOTE: The bolts that holds the turbo to
. the bracket which is fastened to the head
  may need to be loosened to align the turbo
  to the header. The bolts that connect the
 bracket to the head may also need to be
 loosened.

 Install the drivers side héader.

 After the header has been installed replace
 the air conditioning and alternator
 brackets.

 Install the crossover pipe.

 Install the down pipe. Refer to figure "B"

  clearance and to prevent pinching between
  the headers and frame.

  IMPORTANT TIP: These header flanges
  and joints have been carefully surfaced to
  achieve good flatness. Tighten header
  flange bolts and (3) bolt header/turbo
  fignge before tightening bolits on turbo
  housing and turbo brackets to insure
  headers bolt flush to engine and turbo.
