Frankenstein is globally known as the big, green monster that was created in a sketchy lab by using different body parts off of other unfortunate hosts.
While that paints a grim picture, the Frankenstein in question here is something else entirely – although it still involves using parts but not of those off living people.
Creating a different ‘monster’
In an automotive sense, a Frankenstein conversion involves swapping OEM parts of a particular brand and using it on another model in the range for added performance gains. The most common components ‘experimented’ with is the cylinder head or sub assembly but this can also include suspension, braking or even aesthetic parts.
Frankenstein mods are bolt-on bits and does not require additional custom work.
Honda’s B-series range of engines could well be credited with the word Frankenstein as B16, B18 and B20 parts from the likes of the Integra and Civic are mostly interchangeable with one another. While this conversion does not increase power exponentially, it leaves much more room for tuning.
Has to be compatible
Maybe something like the fuel rail or injectors of one particular model is better suited to another to provide better fueling to make more power.
This type of modification is better suited to older performance cars where most models were built around the same mechanical blueprint. Cars these days are too intricate and purpose-built that would render such an action null and void.
It is imperative to do as much research on a particular engine and mechanical parts as possible. The last thing you want to do is buy the parts and find out that they aren’t entirely compatible.
