I think what you want to do is this:
BEGIN
SELECT * INTO v_tmp_regi FROM sulyozas_futamido sf WHERE
sf.termekfajta_id=
a_termekfajta_id AND sf.marka_id=a_marka_id;

DELETE FROM sulyozas_futamido;

FOR v_temp_regi IN SELECT * FROM sulyozas_futamido sf WHERE
sf.termekfajta_id = a_termekfajta_id AND sf.marka_id=a_marka_id LOOP

END LOOP;

FOR v_tmp IN v_tmp_regi LOOP
--I would like to work here with the old recordset!
END LOOP;
^^^^^^^^^^^^^^

END;
