I'm cleaning out my garage of all the old parts from my 86 GTU and 87 T2 and ran across a few old motors I tore down. Looking at what I have, how can I tell the difference between a turbo rotor housing, rotors and side plates from a non-turbo? I want to try and sell these but I don't know what model to list my parts as. Can anybody help me.



Thanks

 

the turbo rotor housings dont have a baffle in the exhaust port.



the na front and rear side housings will have 2 ports and the turbo will only have one



on the center housing the turbo will have larger ports



the turbo rotors will have a deeper combustion chamber recess than the na
