Not to discourage you, but have you thought of the lubrication issue this will create? Most engines (all that I can think of) have oil sumps at the physical bottom of the engine. If you were to lay the engine down flat, without modification you will create oil pump starvation, blow the pump, then seize the engine. This could be remedied by creating a modified sump that makes a 90 degree bend off the original pan mount, but then you will have to modify the pick up tube in order to supply the pump, the oil dipstick will have to be sealed, and a host of other changes will need to be made to prevent pooling. Pooling on one side of the cylinder is going to create uneven wear and quite likely reduce the life of the engine, and much less improtantly reduce the mileage by having to push a puddle out of the way each rotation. In my opinion, it would be easier to create new mount points on a custom frame that is very low to the ground, and mount the engine in stock orientation. If you try to make that honda engine into a horizontal design, I think you may be in for a world of hurt. Just my $0.02.
