Aviva has set a target of achieving £250m pre-tax profit from the acquisition of RAC by the end of 2008.
And it said it plans to capture an additional 1.4 million RAC customers by that date.
Aviva also set its sights on achieving a worldwide combined ratio for its general insurance business of 98%.
The group said it would achieve cost savings of £100m from RAC integration in 2006, up from its original estimate of £80m. This would increase to £130m a year by 2008.
RAC managing director Simon Machell said achieving the targets would not require any more job cuts than the 1,700 originally set out.
He said RAC brand advertising would begin in November, with product advertising in 2006, in order to achieve the "significant increase in revenues" required to meet the targets.
RAC Insurance is planning to increase customer numbers by 900,000 by the end of 2008.
