An extra #7.5 million aid package has been announced by the MG Rover Taskforce to help firms caught up in the Longbridge collapse.
The money will be used to launch an aggressive information and marketing campaign to help Midland suppliers find new customers.
Supply initiative Accelerate will use the money, which has come from Advantage West Midlands, to improve efficiencies and develop new products at more than 1,000 local firms. But in a change to the normal approach, the extra cash will be geared towards winning new work and diversifying away from MG Rover.
Original equipment manufacturers like Bentley in Crewe, Nissan in Sunderland and Honda in Swindon will be targeted as well as car makers and tier one suppliers in Europe.
Dave Malpass, senior operations manager at Accelerate, said: "Our priorities will now be towards promoting the automotive sector and winning new business for our firms.
"In the past we have concentrated on making suppliers meaner and leaner, not been out holding their hands helping them to find customers and markets.
"That is changing and we are looking seriously at targeting where they need to find new business."
About 20,000 jobs could be safeguarded by the money, which is in addition to the #4 million of annual funding to be distributed by Accelerate this year.
It will also involve advising firms on their key competencies and how these can be used to win new business.
Money will also be spent on attending trade shows to fly the flag for local firms, along with visits to European manufacturers and information seminars about developments in the industry.
In the interim, Accelerate said it would help firms win orders in the tail-down period for components, and bundle suppliers together to provide complete systems for OEMs.
Mr Malpass said: "There is a feeling that because of MG Rover collapsing that much of the manufacturing will gone. But the West Midlands is a hot-bed for of manufacturing with a great deal of skills and design and production capacity.
"In the five years after the last Rover crisis many firms reduced their dependency on Longbridge. Now we have to move forward quickly and aggressively."
Nick Paul, chairman of the MG Rover Task Force and AWM, said: "There are hundreds of companies in the West Midlands, particularly in MG Rover's supply chain, facing testing times following its collapse.
" With the additional investment in place, Accelerate has the financial resources available to help another 1,000 SMEs embrace the latest manufacturing practices, innovate the way they work and maximise the advent of new technologies.
"Whilst practical support remains the backbone of the offering, there is also a renewed commitment towards boosting the sector's profile in both the UK and overseas, including Government lobbying and a number of best practice visits, where local companies can showcase their expertise."
