That could depend which retarter system your talking about.
Engine Brake (jake brake): Mounts to valve train to turn engine into air compressor. (Opens exhaust valve just before TDC of compression stroke)
Having larger displacement I do believe would create better braking over a smaller engine.
Exhaust brake: uses a sliding gate or valve to cause a restriction in the exhaust system after the turbocharger.
Larger displacement would be better here also, if the restriction is the same on both motors.
Hydraulic Retarter: Use a device similiar to a torque converter, using engine oil as a resistance in the retarding device. Caterpillar Brakesaver
Driveline Brake: Uses the force of electromagnets as a resistance on the driveline of the vehicle. Usually used on large mining vehicles.
