V6- N/A tuning options/companies?
For the 24v V6, what would be the best route for naturally aspirated tuning? I've heard of enlarging the 2.5 to 2.8 and the 3.0 to 3.5. Are the 2.5 based engines peppier than the longer stroke engines? I'd be interested in swapping the engine into a Volvo wagon, kind of a long story. It'll be a track car and relatively light. I don't have the skills or resources to fabricate many parts myself. So that being said, how much power could I could get, how high could it rev, how much would it cost, and where could I get the parts from? Links would be great.
