St165 hose problem

Sun Jun 26, 2016 3:50 am

Hello everyone. About a year ago I bought a st165 that needed some tlc. I recently changed a few hoses and changed out the clutch. I noticed a hose and have no freaking idea where it goes. Can someone please lend me and eye and knowledge on where this connects to. Some pictures would be fantastic :) I'm having trouble uploading images. Pictures will come soon. Thank you.

Please any info is better than no info. This obstacle is the only thing preventing me from finishing my car! :(

Thx in advance

Looks like one of the coolant lines that runs to the throttle body?

From that angle I'm not sure, but I'm guessing that it's the hose that connects your turbo to the Turbo-VSV. Check out this photo and see if that helps narrow it down:

Hey Scott nice picture. But based on that I don't have the proper angel to see the tubing. Zalus, I was thinking the same thing but I couldn't find a broken or empty spot. Can you guys show me what coolent pipes go through that general area or for coolent to the throttle body?

Thank you guys.

Try this one:

I'll keep digging through photos, but I think this is as good as I've got.

I found one that shows the hoses that supply heat to the throttle body, and I confirmed with the BGB that they are the ones:

I took a lot of pictures of areas that are hard to see with the engine in the car, but apparently I didn't get good enough shots of that area. As you are undoubtedly painfully aware, there is a lot of stuff in the way that obscures that particular hose.

I think this 1 is it! Where does it go though?

If that's the one, then that hose goes to the vsv#2 to the right of the tvis vacuum reservoir looking at Scott's last jpg picture.

Crap, I an looking at his last pick I can't seem to follow it. I am sorry, please be specific. Sorry for my ignorance.

That one and this one are the same hose:

You can see that it connects to the TurboVSV.

If you look closely in this pic: http://planetcampbell.us/P1030051.JPG, you can see there is a cap and zip-tie on the other end of the metal section. That cap is there because I use a ball&spring type manual boost controller and have bypassed the TurboVSV. If you are also using some sort of alternate boost controller (like anyone in their right mind) then you don't really "need" that hose. I'm trying to keep my car close to stock so I kept it and can easily remove the boost controller and put it back to stock if I decide to someday.

Wow. I have no idea how the hell I am going to get to that, without having to Jack up the car and remove the N&S cross member.

It could be worse. See the green connector on the other end of the TurboVSV? I forgot to plug that in.

When I had everything else hooked back up, I still had a mysterious wire with a green connector on it that I couldn't figure out where it belonged. Eventually while looking through pictures I found the matching green connector on that VSV. I wasted way too much time trying to figure out how to plug it back in and finally decided to leave it as is since I'm not using it anyway.

Ty so much, I will look at that as soon as I can. I am currently not near my car because it's at a different house.

OK man o man! So excited. Got so much plug in and almost ready to give it it's first crank in a little over a year soon.

Another weird 1, I'll try and research it myself as well. But for some weird reason I can't seem to find my negative terminal wire to the battery. Honestly have no idea where it is. Is it suppose to be somewhere specific, or can I just get another and connect it to the battery and ground it to the chassis?
