I have been reading the bbs late into the night, doing a lot of searching on a whole grocery list of things... but haven't stumbled on this yet:

 

was thinking of putting a 205 TMIC on my ea82T for the time being, until I need it for the 'big build' (ej22) (since I already have it lying around)

 

the IC has a recirc valve on it, I think I could block it off or I could use it, I'm not sure

 

if I did use it, the vaccum line on the diaphragm could go to an unused port on the ea throttle body post maf, yeah?

 

but what does the actual port, the one that opens and allows some bypass, tie back into?

 

forgive my newbness to this side of the world

 

** edit, this is really, 'where does this go' on the 205, not 'where does this go' on my car (retrofitting) **

On turbo motors, the bypass valve needs to be fitted somewhere on the piping between the discharge side of turbo and throttle plate/body. For this instance, it's on the intercooler. It needs to be piped back to the piping before the compressor side of the turbo.

 

The bypass valve vents the pressurized air that gets trapped in the intercooler/piping when the throttle plate snaps shut. This keeps the turbo compressor from going into surge and potentially flowing backwards. The vacuum source on the bypass valve needs to be hooked up to a port on the intake manifold.

 

Hope that helps.

Well explained, I now know the function as well as how to tie it into my existing system. Thank you, Legacy Triple 7.

You're welcome.
