is there a special spot on the turbo for the gauge line ?

 

the tighter the spring the more boost. thats a pretty ghetto setup, look at the heath turbo master, thats the setup you wanna copy. Also, that tube going into the oil filler needs to go to that plugged hole in the intake. its not gonna work right in the filler tube. He moved it to stop it from getting oil in the turbo, but IIRC the canister does rely on vacuum to work right. the way its set up now, it might as well just be removed and the hole plugged, which will probably cause the motor to push oil out of wherever is the next easiest place.

as for the boost line, you need to remove the intake plenum on top of the manifold and drill and tap it.

on a second look, that canister is supposed to be on the passenger side valve cover with the tube into the intake tube. Someone else chime in if i'm wrong, but it looks to me like its basically back asswards.

 

thanks for the help that canister was on the the intake i moved everthing outta the way to take the pic where is the right spot for that canister to be on the valve cover ? i know nothing about these motors so i need some help, i only bought the truck for 700 bucks, so when i bought i knew there was gonna be some issues that need to be addressed i appreciate the feedback guys i am lost wit this thing .

 

Is the old wast gate still around here good way to make one



Here's the adj controller i fabbed up. Hope it helps ya'll.
First pic is the original with the "lip" ground off and pop'd apart with the new 1/4" rod i bent. Second is the thing attached, third is the adj end. Total cost $5.97. I measured the length between the inside of the lever hole to the step on the original rod. Then when i installed it, made the length the same. 10 5/8" on the GM-3. After i get the truck back together, i'll use the pyro & boost gauges to set the boost and turn up the 4911 if needed.

 

thats how i got the truck wit that set up on it where can i find all those parts to your set up ?

 

you get at any hardware store

 

cool thanks, what kind of spring do i need to get hardness or soft does it matter .

 

spring that was used wasn't much more then spring that was in wast gate. it not going matter cause you be able to adjust it with the nut
