Are there any aftermarket crankshaft options for the 2ar fe. Looking for transmission, crank and head options

 

Not that I know of. If I were you, I'd try calling up one of the companies that developed parts for their cars (Dezod, PTuning, GReddy, etc.) and see if they are parting out anything. When my car was under the knife, I was lucky enough to get the head out of one of Descendant's cars.
