What moron developed this?!? Some help with the aculator valve on a Evo 16G please

[whitetiger777]

I managed to get the Evo 16G into my car with out a major issue. I didn't even break any studs. I have run into a rather fustrating problem though. The nipple that I conect the tube that come from my boost controller is set up in a bad way. The aculator valve is posistioned at the bottom of the turbo when installed in my car. The problem is, that the nipple on the aculator is pointing straight up. What is happening is that the air intake tube is coming on contact with that nipple and crimping the hose. I am constantly having to be carefull not to over boost because the turbo can not open it's waste gate. I thought about bending the nipple so that I could move it out from under the intake, but I'm afraid I will break it, and someone else said that theirs started to leak when they attempted that. Has someone found out how to avoid this problem? If so how do I make it work?

Take a pic so we can make recommendations based on what's happening with your setup..

It sounds like you need to take your car to a shop that specializes in connecting vacuum lines.

I have an evo 16g and mine isnt like that. But you coudl get a wastegate actuator off another 16g or even a 14b. I noticed my old 14b had the nipple pointin in a diff direction. More towards the radiator. Couldnt hurt to try that and im sure it wouldnt be all that expensive.

post a pic. Generally you can bend the nipple a tad if it's just a slight rub.

You could always just cut a little bit off the wastegate nipple and then put the boost controller hose and then secure it with a zip tie. I also had this problem but i never had the issue with the boost controller line kinking or anything so you shouldn't really worry about that. Only problem i had with the evoIII was boost spikes as this is common on this turbo anyway

just bend it a little and zip tie it, no big deal.

I have a small16G and it's the same, the nipple for the wastegate actuator is pointing straight at the inlet for the compressor housing. it gets kinda squished when you put the intake on, but it's no big deal.

I have the EVO3 and I don't have this problem. Can you take a picture so that we can get a visual?

That was very funny!

Sad part is, it wasn't mean to be.

The easiest fix for that problem: Use zipties to pull the intake up and out of the way.

I have heard 2 other people in my club talk about an aftermarket intake resting on the wastegate nipple. Found the same thing for my car. I attach 4 of the large size zipties together and wrapped it around the side closest to the MAF/airfilter and my UICP. It maybe pulls the intake up 2 inches but it allows it just enough clearance to clear the nipple. If you need pics, I could probably take some, but its very simple to figure out.

I did not have this problem, but can't visualize it either. What generation car is it?

 

[whitetiger777]

Ok, so I bent the nipple tword the passender side of the car and tightned it with a zip tie. The hose now has complete clearance, but I'm still over boosting. The turbo hits 20 psi fast. I don't have the fuel system to handle this. I want to run about 12 to 15 psi untill I have the money to get a set of 660cc injectors and a 195 fuel pump. I am not hearing my O2 dump tube, and it vents into the atmosphere. How do I get my boost down? I'm using a turbo Xs high performance manual boost controller.

 

[Drag_S13]

First, connect the vacuum lines without the boost controller connected. If the problem goes away, you know it isn't the turbo. If it remains, look at where you bent it and see if its cracked or something. Otherwise, sell the junky ass TurboXS boost controller and buy either a Hallman or a EBC.

Umm about your boost controller is it the one that has the course adjustment and the fine adjustment on it? Make sure to check the wastegate actuator and see if something is holding from opening etc. Check your boost controller again and make sure its turned all the way down

Holy smokes a big thread about a vaccume line kinking. Geezus christ and it's in the performance section.

 

[whitetiger777]

How do I hook up the vacume line with out the boost controller? Unlike the t-25 there is no nipple on the turbo. Only the aculator valve.

 

[whitetiger777]

Ok, just to clear up a few things, the car is a 2g AWD, the boost controller is the high performace (with corse and fine adjustment).

???? You hook it up the exact same way you have it now except you remove the boost controller? How do you have your boost controller hooked up now? You need a source for pressure somewhere, then to the boost controller & then to the wg actuator. Did you not hook up a pressure source to the boost controller? Just the controller to the wg actuator? I sure hope not.

 

[whitetiger777]

I spliced it into the line coming from the throttel body.

Perhaps you should do a followup on the how-to install an MBC. What are those of us without an MBC supposed to do?!

Maybe I could do an "How to install a boost gauge?"

I'll start working on it now

 

[rob_rousseau]

Tee into the vacuum line between the intake manifold and bypass valve. Then hook one end up to your MBC and the other end to the actuator... don't do it backwards and for f... sake be careful
