I will be anxious to hear how your homebrew system
works out.  I don't really have any good suggestions on
injection systems but thought I might mention a few
things on the pollution equipment.

A good oxygen sensor is used on the Volvo and I believe
is made by Bosch.  This is the Lamba-Sond which is used
to measure the lambda point of engine operation.
This is a point at which the engine operates which
produces a mixture of gasses which can be handled
by a three way catalytic converter.  The lambda point
is a very exacting mixture and so the air/fuel mixture
must be very carefully controlled.  This is done with
the Lambda Sond and a magic black box to properly 
control the fuel mixture.  This with the three way converter
and air pump is probably your best bet to meet the pollution
requirements.  The only problem is 
ignition timing must be somewhat retarded as well and so
perfomance will drop.  I don't think you will have quite
the performance you had before.

You might also look into the methods used on the new
Mustang or some other American models where performance
levels are beginning to approach pre pollution days.
