where this go

[mr84ss]

Hi fam. I recently bought my first gn from a young guy who it was given to as a fathet/son ptojecr and he lost interest. Its been sitting for a couple of years and it runs just not rough. So im trying to hook up the lost connection and go from there. Do anybody know wjere this hose go? It was just laying down by the battery. Its attached to the bottom of the turbo

It connects to the waste gate nipple. Is there an adjustable boost controller not shown ?

Get that Fram filter off of your car....

No. It doesn't have a adjustable boost controller. I see the waste gate is adjustable. I wonder why they didnt have the hose connected, smh. Will it hurt by not having a adjustable boost controller?

You need to show us what those hoses go to at the bottom of the picture that we cant see.

 

[mr84ss]

Turbo dave. What hoses are you referring to?

 

[mr84ss]

Found this laying in the passenger valve cover

That's the factory wastegate solenoid that was on the passenger side valve cover shown in that last pic you posted.
There should be a hose connected to the bigger port on it and the smaller port would of had a foam filter attached to it.

This is how the factory setup looked hooked up off the assembly line, the foam filter vanished long ago but isnt important.

I know you have a different turbo and other things been added that differ from what i have, but i don't believe that wastegate solenoid is suppose to be bypassed and left un-hooked unless you're running a boost controller of some type to my knowledge.
There has to be something managing the boost and if there isn't a boost controller there to do the function of what the wastegate solenoid did, it's gonna be ugly real quick.

He told me how its was running at 20ibs and had a different chip.where would the boost controller be located? Sorry if im asking dumb question

 

[Nascar83Fan]

Is there any way you can take pictures of where the rubber hoses including the one that isnt hooked up on the one end so we can see what they are connected to on the other end that are coming off the turbo?

I am running an aftermarket TT chip, but i don't have a boost controller installed. I'm still letting the wastegate solenoid handle the management of the wastegate holding and blowing off boost pressures. I'm also only at 15-17 psi of boost with the stocker turbo.

That picture I took is the hose coming off the turbo. Its just curled up and I laid it up there to take the picture. Its a long hose and it was laying over behind the battery. What other picture should I take?

I remember when I got mine.It was a pluming nightmare,had a old Ken Bell chip ,stock wast gate and turbo ,but hoses went everywhere ,switches in the ash tray solenoids under the hood .Got me a good book(It actually came with factory service manuals)Put it back as stock as I could ,got red of some old weird hot -wire to the stock pump got a TT chip and injectors, TTs hot wire kit and new pump.Then the car actually ran right.The owner before you may have been going in the right direction but you don't know what direction that was.I think you should be able to plumb that wast gate the same as stock

Turbo dave. What hoses are you referring to?

The hoses you pictured. the one's you're asking about. They all dissapear off the bottom of your picture. Where do they go? A better picture would do.

 

[mr84ss]

Do you think I can run a hose off the big nipple on solenoid and then tee it off to the nipple on the bottom of the turbo and nipple on the waste gate?

 

[hensleyt]

That post was not a lot of help I now.But in those pic I see a lot of hodgepodge.The ground will NOT work right, where it is .
In the search ,Type (Applied Technologies waste gate) some good reading there

 

[Nascar83Fan]

Yeah i noticed a bit of wiring being messed with, i have a feeling the negative going from battery to where they have it hooked at probably has alot to do with it running rough. A flaky ground will make them run bad, not sure where they thought hooking it up there was a great idea. Fix that and get the other stuff corrected, that should hopefully help be rid of those gremlins.
Did it come with a scanmaster and other items to monitor things?

Not sure, but does that brass T on the turbo look like it might be a DIY bleed off boost controller? I've seen things like that and it's coming off the compressor side then the hose off of it. That might be why there is no boost controller separate.

No it didn't come with a scanmaster. I know I need to get one asap. Have to save up the $200 to get it. Where should the ground be hooked to thats on the turbo?

 

[Nascar83Fan]

On the front of the passenger side of the engine block there was a bolt that held on part of the factory turbo support bracket and it also was the factory location of where the fat ground cable end was bolted at towards the bottom of the front of the block. The picture below should help with giving you an idea of where to look, it's not easy to reach being near the passenger header section that the turbo attaches to. If they used a shorter length negative battery cable and it isnt attached somewhere on the engine block, you're not gonna have a good solid ground which is from the pictures you posted the case. So you might have to get a new negative battery cable to properly hook the ground up.

I moved the ground wire to the front of the passenger side head. Is this correct?
