Alright, I'm still kicking around with the engine to try and get it running right, and this mess of vacuum lines has me fairly well stumped. I've found at least three different diagrams for the vacuum lines, and there are always a few differences between the diagrams and what I'm working with. Engine is an EJ20R, believed to be pulled from a 1996 GTB. Has the yellow top injectors and VF-18/19 turbos.

I'll post what information I've come across here, and the differences, and maybe someone will be able to help me without me having to bribe people to go out and look under the hood for me.

This is the solenoid box I'm working with: http://img174.imageshack.us/img174/3701/p1000855.jpg

First diagram I've found: http://www.veloce.pwp.blueyonder.co.uk/ ... 5B1%5D.pdf (http://www.veloce.pwp.blueyonder.co.uk/TT%20PDFs/Solenoid%20Box%5B1%5D.pdf)
This one is either incomplete or different from my engine, as it shows less inputs/outputs from the solenoid box than I have.

Second: http://www.veloce.pwp.blueyonder.co.uk/ ... ox%205.jpg (http://www.veloce.pwp.blueyonder.co.uk/Twin%20Turbo%20Operation/TT%20Solenoid%20Box%205.jpg)

This is a better view of the inside of the solenoid box, but as you can see between mine and this one, mine has two extra sensors, and the vacuum lines are slightly different because of it. the 15/16 ports on the box are again unused in the diagram, where mine are functional.

Third: http://www.veloce.pwp.blueyonder.co.uk/ ... oSetup.bmp (http://www.veloce.pwp.blueyonder.co.uk/Otherttdocs/TwinTurboSetup.bmp)
This one shows the correct number of lines being used, but my engine doesn't have a wastegate on the secondary turbo as shown.

Any ideas?

Thanks!

I have no info from the TT engines, but if you get stuck and don't get any answers PM Reuben as he's pretty familiar with the TT setup.
