Did the waste gate itself actually break off or did the controller break off? I don't know of any other turbos on other trucks that will fit.

See the arm coming out of the turbo?

Wire it off to something so the wastegate stays close.

Watch your eyes on EGT and boost while it's like that.

The only problem with wiring the wastgate closed is the computer will defuel some where around 14psi. You can do it but you have to remove the manifold pressure sensor. You can't unplug it just pull the sensor out and plug the hole it came out of. Your check engine light will come on and you will need a boost gauge. Some people think you might blow and engine that way I don't know. I have seen a lot of them ran that way for a long time but it scars me to bad to do it.

Heath sells a kit for the wastegate you can also make them. 8 psi is low for a wired shut wastegate does the truck still have the factory exhaust and cat on it? If so the cat is probably clogged.
