1# I have a t25 with internal wg! well on the wg there is a tiny little brass connector! where do i connect it to? also have the same connector on the compressor housing which is on some sort of valve

2# Same turbo is water and oil cooled i have been told that just cooling it with oil will be fine!


thanks in advance

 

1) I'm not 100% sure, but I believe you're talking about the nipples right? If so, you connect them together witha vacuum hose, and the boost built up in the compressor housing, will tell the wastegate when to open.

2) yea you'll be fine

 

just connect the wg to any vacuum (or boost in this case) source, the nipple on the compressor is probably the right one.

It's so easy to run water to it you might as well.

 

Yeah, running water to the turbo also will lower it's temperatures making it last longer. There was a reason they started using oil and water cooled

 

the oil is not a "coolant!" It lubricates the moving parts inside the turbo! This is a common misconception

 

The oil is too a coolant!
The reason you let the car idle is to keep the oil running through the turbo while the heat goes out of the exhaust housing and exhaust manifold. As soon as the oil flow stops the center cartridge gets soaked with heat so it's best to keep it minimal by letting the car idle.
The purpose of running engine coolant to the center cartridge is not for cooling while the engine is running, the oil does a pretty good job at that.
The engine coolant boils in the center cartridge after the engine shuts down and forms a natural recirculation. Thus keeping the heat from coking the oil and frying the seals.

 

Exactly what he said ^^^^

 

Thanks for the help i really appreciate it!!!! i would like to run a boost guage! should i do this of the intake manifold! i have to nipples on my im! one goes to the fuel rail! and the othe goes from the top of the manifold to some other sort of valve at the base of the manifold! i think its red in color!! any ideas! once again thanks for the help
