Hi All ,

I have just bought a S2 turbo off a 1990 RX7 this turbo has no oil or water lines on it and I am using the turbo on a project and as I have a twin turbo RX7 I have no idear what is oil and water on the single turbo.
Question;
We think the large line on the bottem is oil return???
The 2 at the top, we think the closest one to the block at the top of the turbo is water?? and the other is oil??
There is 1 on it's own on the side of the turbo is that oil or water??

Thanks

Graham
