Re:What are these two things for? *Look at Pix!
 

I think he's talking about the two fitting on the compressor side. They are hookups for the wastegate, why there are two not sure, but you could use one as a fitting for a boost gauge :) oh, and as a side, its not from a z32 but it my be from a z31.

1. Nipples that normally went to the wastegate actuator, you will need to plug off one of them, and just use one.

2. Compressor Inlet

3. Exhaust Inlet

4/6 Water Lines/In-Out (either direction doesnt matter)

5. Oil Feed

7. Exhaust wheel dump (exit)

8. Wastegate Dump hole (exhaust)

That help?
