How do I disable the turbo?

[hpram99]

I know it's a weird-ass question, but what is the easiest, fastest way to eliminate as much boost as possible? Such as... forcing the wastegate to stay fully open. I'm looking for directions...

In case you can't see my profile, It's a fuggerd up 98 GSX

I believe this was discussed by RRE I THINK, eitherway. They needed it incase you blow a hole through your intercooler piping. The way they did it was, keep the wastegate open by removing the cotter pin, and tape up the hole in the I/C piping. I think i'm just throwing shit out my ass... whatever...
Then I forget what they did about the unmetered air...? anyone wanna fill in the blanks?

Pull the cotter pin out of the wastegate arm, and take the arm off. This is the best you can get without major modifications. On my car which is all stock with a 14 I still get 1-2psi at 6500..hope that helps!

You could also run a vacuum hose from the pressure source straight to the wastegate actuator and completely bypass a boost controller. This isn't as effective as the method mentioned above since the turbo has to spool first in order to open the wastegate, but it is an alternative.

Simply taking the cotter pin out and disconnecting the wastegate actuator will leave the wastegate closed, which is the opposite of what I want.

Or does the wastegate itself just flap around without the actuator to control it?

it will just flap around freely then.

Great!, wasn't sure if it was spring loaded somehow..

It's 7 AM and 20 degrees out... but I'm walking outside anyway to try this out.

Thanks for your help

Well, the car is flappy now. Although it doesn't exactly flap around, I would still like to tie a wire around it to hold it open. I'm still getting a little positive pressure, but nothing to worry about.
Next up, fixing the BOV so it's NOT venting to the atmosphere.
Then the little issue with clutch slip...
It's just too damn cold out right now.

I removed the cotter pin and the actuator arm off so that way when my chick takes my car there are no joy rides
