Yes, the 3RZ is the 2.7L found in several T100's and Taco's.
I have looked at the Marlin dual case page but it appears as if the adapters that are needed are in the development process.  Does any one know if they are currently available?  Marlin does not show a price.  Maybe someone from Marlin can let me know when these adapters will be available and a price....
