on a sti v2 96 with the 3 port boost solenoid ,
the bottom pipe has a restrictor in it , so when you take this pipe off you should then overshoot your boost target as it will feed air away from the actuator,
the reson i ask about this is, been haveing trouble getting correct boost for a while now ,have cleaned all sensors /solenoids ,have cut the rubber pipe work back a bit so it is a tight fit and wanted to see if by changeing the restrictor it would raise boost to corret level,
went for a spin with the pipe off and could not get it ovaer 1 bar
so now is this right

should there be a restrictor in that pipe ?

my understanding of the 3 ports is that they dont need the restrictor.

 

yeah they all have them on early classics,have regapped plugs to 6.3 mm ,see what that does,
ill get there in the end
by the way nice car you have there

 

cheers - I really need to update that page ... it is a little out of date and uderspecced there
