i think its the same style pump for mech and lifter motors. you will need to have the diesel version. the turbo diesel oil pump has more flow than n/a due to piston oil squirters, and the presence of the turbo.
I'm seeing a part number of 028 115 105 G for the oil pump as per ETKA... models JR,MF,RA,SB price $136 jobber and $157 retail.
