On the Saph 4x4 models are 2 types of turbo's,the 00/89-01/90 models have this part number 465189-0001 and the 01/90-02/93 have this part number 465189-0003.
Is there a difference between these 2 models,and can you switch them between both Saphs?

Someone?

 

only difference is the exhaust housing on the later 0003 has a threaded position to mount the lambda sensor that is used on post'92 cars, otherwise identical AFAIK
