I have a question. I installed a pre turbo wi from wannaspeed
,my question is the aire that supply the nozzle , is this ok to hook it up from the vacuum manifold? where i have my map sensor connected and also all my other vacuum devices?

Or must it come from the turbo compressor side? None of the wi should be hook up to this manifold?

 

No..

You want a positive pressure area to feed the nozzle, not vacuum. This is going to essentially be anywhere from the turbo compressor housing to BEFORE the throttle body. Turbo piping is good as well. Your tank pressurization line will also use this location.

Additionally, ensure you have no other devices sharing vacuum with your MAP sensor.
