Ok, so I get that if I want to lower boost pressure under the stock setting I need to cut the actuator rod, thread both ends and lengthen the actuator rod. My question is: wouldn't that create excessive turbo lag??
Does anyone know of a way to drop an internal wastegate's pressure and not have more lag?

Was kind of brainstorming and I think that if you used a spring held against the underneath side of the housing, you could alter the spring rate that way.
So maybe cut and thread both ends, then on the side closest to the actuator, slide a spring on, a nut, a washer of larger outer diameter than the spring, a nut and a locknut And then the coupler and the end that connects to the flapper?

If that would work, then you could control boost by canceling out some of the spring rate in the actuator with the spring you just installed against the housing and use the coupler to help maintain the stock actuator rod length, right?

If anyone has any experience or insights on this, I'd very much appreciate it. Otherwise, I'll just try it and see what happens.

 

that question is of my interess but i dont know the answer... i hope that someone knows how to do it

 

Ok, I did the spring thing. A lot of people would frown on it, and in some cases, they'd be right. Heat is a consideration of course, but my turbo gets a pretty good breeze blowing over it. I use mine for purposes of more boost, and it works very well, so I don't see why you shouldn't use one to actually lighten the load so to speak.

 

deleted cuz im an idiot :P

 

cool. thanks for the replies. i probably won't be able to do anything with it this week, but when I get around to it, I'll post the results w/ pics.

 

Hey Vortec-F, I'm thinking about turbo charging my stock 2.8 fiero gt (HMT of course) not a kit, I realize you're no longer stock 2.8, but do you have any advice for a fellow 2 seater?

 

Engine swap.

Seriously. More power, better reliability, better gas mileage, and less money. The 2.8 is a waste of anything even remotely related to time, money, energy, thought, gasoline, oil, water, and air.
