1)Dig up a corpse from your local graveyard (you may need to mix and match parts to get what you're looking for),
2)Attach bolts to the sides of its neck (something that conducts electricity well, copper works great),
3)Place corpse on a platform (a car lift works great, but requires removing the roof of your shop)
4)Wait for lightening storm, lift corpse to attract lightening... the rest should be pretty self-explanitory

Real answer: "Frankenstein" is a non-technical term that refers to a motor that has various bits and pieces from different sources. For instance, LS block, ITR pistons and a B16 head might be called "frankenstein." This applies to any make, not just hondas. Basically its just a stupid term people use to sound cool. I would refer to the afore mentioned motor as an ls-vtec, personally.
