No, they are completely different. Different input length, different gear size/ratio, different bearing size, different length..
The input on the V6 chain drive t/case is the sun gear for the planetary gear drive system.
The Turbo Input is just a regular gear drive input.
The two happen to both have the same 23-spline dimensions (spline pitch and diamater), and using a V6 adapter plate of about 1/2", will work with a R150F V6 transmission.
