You retain most of the fuel injection components from the '84.  I'm not sure
about the throttle body though.  I converted my '85 to use a 2.1 and the '85
throttlebody fit the 2.1.  Yours may not.  Seems that there is some problem
with throttle position switches when you put the '87 throttle body in and try
to hook it up.  The ECU, AFM and all the other goodies stay.  It will
basically be a 2.1 digijet.
