T2 stock boost control components

[Aries_Turbo]

Ok, I need to convert my k car back to 87 T2 style boost control so that I can use the ecm to control it. I run Geof Allans Blueberry 60 with my 2.5L mods done to the code so I have control over all the boost functions...

now what I need to know is the stock size of the "orifice" that is in this diagram.

also I assume that the thing marked "bleed" is just one of those little rubber things that has a piece of filter media in it to keep dust out. i think it is but all of my turbo cars have been converted and built from non turbo cars (minus the GTC but its apart right now) so I dont have alot of experience with a stock, unmolested harness and ive always used graingers.

also, what was the stock wastegate tension set to? mine somewhere around 11psi lol.

I don't know the size, but the stock orifice is the yellow one on the T-II cars. You probably have 10 of them in the bottom of your toolbox somewhere!

The bleed is just the open port on the solenoid. Originally, the solenoid had a foam filter on it, which is what you are seeing in the diagram.
