wastegate problems agian.
 

Is there any way to see if the wg is opening or not? For some reason im not getting any boost and i trouble shoot it to being the wastegate. Is there anyway to see if the spring is working properly?

im working on my friends car. its a turboed laser.

in other words, you've checked all the piping for any signs of leakage right? To check the wastegate, move the rod side to side. The only way to acurately check it is to take the whole turbo assembly out and hook up a pressure gauge with pressure source to the diaphragm. Once you do that then observe the gate open as you apply pressure on the diaphragm

thanks! yes we check all lines and pipes.

...or it could be that the gate itself is completely worn out.....

thats worse case scenerio.:o

yep

well, the fawking thing blew. we replaced it with another one out of a -j-yard.......IT DOESNT WORK EITHER!!!!:mad:

time to get an external bro...

how hard to switch over? do i need to replace anything else?

i might take the two bad ones apart and see if i cant fix one with the other.

it'll take a few hours of fabrication. You will have to find a way to keep the internal gate shut or open if you place the external gate somewhere on the manifold runner/collector

gawd damn. at least its not my car or money.

maybe hell just buy a brand new one.
