hey I'm back at work on the devil of a turbo wagon. Got some vacumn lines unplugged. They are coming from the module bolted to the front of the passenger side strut tower. Two of the lines are going somewhere, but there are two that are loose. and then there is one vacumn line off the intake thats open.

 

What is the module bolted to the strut tower? its kinda sandwiched in-between the airbox/MAF and the tower

I'll post this, then I'll try to find the answer

Here's a FSM for a 1988 Subaru Turbo (very helpful)

The devise you are referring to is called the waste gate control duty solenoid.

 

It should have three rubber lines and one two wire electrical connection.

 

One line goes to the waste gate, one to the hose barb on the turbo pressure outlet

and the third goes to the MAF to turbo pipe (it is just a "breather" line)

 

If it is not connected properly the waste gate will not control the boost pressure.

 

Hope this helps

i actually dont have that device in my rx, i have the line going from the compressor right into the waist gate, the bost is normal, doesnt boost over 10psi. the other thing i that there, i tihink, its the boost sensor that turns on the little turbo light in the dash, needless to say, mine doesnt come on.

if its an 85 to early 87 turbo car...it should be the cruise box if its rather low...the turbo dash light and boost controller should be right up high beside the injector resistior block.

thanks guys for the responses. if that wasn't hooked up right, would it make the turbo heat up (Glow red)

Possibly.....but, mine glows all the time.

thats cause you got a heavy right foot.

Ummmmmmm...........No I don't think it would. Usually exhaust parts start to glow red when the engine has been run really hard for an extended period of time or if your engine starts leaning out and not getting enough fuel, and that my friend will make for bad Joo-Joo!(ex.: melted piston(s), burnt valves, blown headgasket, etc.)

So what?
