A guy named Tim Wright has been designing an open source sportscar (mid engine Alfa V6+Alfa transaxle) and has 3D CAD modelled the engine and weighed it in minute detail. His chassis is a bit too wide and more of a track day car with limited door access but it is very interesting. In the interests of open source he might contribute his measurements and ideas (he is a suspension designer by trade)
