I'm building a mid-engined road race car, and am most likely going to use a honda engine, transmission, and some kind of LSD. I'm looking for information on general overall dimensions of engines, transmissions, axels, etc. I'm also looking for locations of engine and transmission mounting points. Weights of engines and transmissions would be great as well.

Does anyone have any idea where I can get some of this information? Even basic, rough ideas would be helpful for some general planning. Thanks!
