Brabus, AMG et al would have some ideas for that engine, however they will likely be expensive. The problem you'll have is it's a fairly rare engine so there won't be a lot of knowledge out there about it. Price/power wise, a turbo or supercharger conversion might be best, if it would fit under the bonnet! Guys at mbclub.co.uk might have some ideas.
