Boxer Engine, Do some 3D Modelling

Can anyone provide a Solidworks 3d model of a boxer type engine? A previously finished work should do just fine with all the details intact. Just need it for reference. Ideally close/equal to 20kW power with bore/stroke of 72mm/65mm. Again, any config that will be closes to the power. A sample photo is attached as well. A design analysis on some of the following below only IF you have it would also be a really great help although not entirely relevant. -Bore and stroke, number of cylinders (size, weight P&E, cost aspects) -Profile, cooling & heat rejection -Combustion system type -Lubrication system -Fuel system (& ignition system if SI) -Balancing and shaking forces -General layout, including starter & generator option -Port timings & areas using Schweitzer procedure, zero dimensional (empirical) & -AVL Boost 1D engine performance simulation. -Cranktrain system options (classical and RDM type) -Cooling system -Crankcase structure -Auxiliary package/drives -Intake & Exhaust system
