Hello

I have a 99 turbo 2000 WRX that I have been trying to put back together now for an entire year and I am stuck on what I am hoping is the last few steps. I am trying to connect up the vacuum hose/ intake setup back together, some of which was already in place and some that wasn't
I have made a little diagram of how it is currently connected and I have an idea of what I need to change but an really not sure and don't wanna damage her after all the work so far.



I think that I need to
connect 5 to 7
3 should go to the return on the "BOV"
1 should go to the vacuum for the "BOV"
I have search the pages and put this together so far with what i have found from diagrams of not quite the same car, any help would be very much appreciated.
thank you

This is all the same apart from this being a three port boost solenoid. You will need a T piece and a pill from the turbo to the actuator.

Above
Pipes 5, 10 and 2 go to turbo inlet pipe.
Pipes 9 &11 connect to the heads

Thanks for all the help and diagrams, I think I understand where everything is meant to go now.

I have connected it all up as shown last night with the pipes and clamps I already had and I can now start the car but it won't idle, it starts first time then as it drops to 1k RPM is starts to stutter and die, if I rev it or try to raise the RPM it back fires a few times and then dies anyway.

I have ordered a bunch of new clips and hoses as well as a MAF (just in case). Once they arrive and I put it all on hopefully it will be okay.

one thing I did notice last night that I didn't put in my diagram was the vacuum off the throttle body that seems to have a vacuum hose attached to nowhere sitting on it. 🤨

Thank you all again. 🙂

The only pipes attached to the throttle body, AFAIK, apart from the obvious inlet air pipe are the two cooling water connections.

On the earlier cars there was a small brass 4mm ish pipe for the purge system. Maybe someone has fitted an earlier throttle body. I forget when it changed but the throttle cable is on the opposite side on the earlier cars which may help. Pipe I on above diagram.

Thats the wee pipe sitting right on top in the centre ot the throttle body. With a right angle bend on it.
