Me, and a couple of buddies installed an Efini Y-Pipe on my car last weekend. We really did not run into much trouble, and had a good time with it. I could not drive the car throughout the week because of Snow on the roads. I finally got to take it for a spin yesterday, and I am having a problem. My secondary Turbo is only spooling to about 2psi. The Primary is hitting 12psi like it is its job, but Something is up with the secondary. Anyone have a problem like this before? Is there a specific thing I should check? Doesnt seem like anything is loose, and we took our time, and did it right. Any Help Would Be Great!! Thanks, Mike

Probably one of the vaccuum lines down there disconnected or switched. If it was that big of a boost leak you wouldnt have hit 12psi on the primary.

I just talked to a mechanic, and he said I probubly got two of the hoses mixed up. Do you think that could be the problem? If so which two hoses?

Mfanto

I have the M2 Airbox, mabe I got something in the back of it mixed up. Also it seems like my BOV is blowing more air then usual. Unless im crazy. Help me out.

Get the vacuum diagram out and check your lines. There's a vacuum line going to the butterfly valve in the Y-pipe - if that's mixed up with one of the other lines in that area, you'll have no secondary boost.

Should be pretty easy to find.

The other possibility is the 90 degree hose from the Y-pipe to the charge relief valve. If it's not on tight, or if it's old, hard, and cracked, it can and will leak boost. But, I don't think it would leak THAT much boost.

Anyhow, start with the vacuum hose diagram. Should take like 5 minutes to verify everything.

Anyone have this diagram? Or any other suggestions?

Print that sucker out and keep it handy. VERY helpful for under the hood work!

WOW that is a crazy diagram...Thanks!! Do you think it is possible I just mixed up two of the hoses that go to the Airbox?

Mfanto

I know someone knows the problem. It has to do with the Y-Pipe because before I installed it I was fine.

If you are talking about the BOV and CRV hoses then no it can't. Both valves can be switched temporarily and will still work normally.

Mfanto

I just don't see what the problem could be. The car ran fine before we did this Mod.

Check the vacum hoses on the back of the Y-pipe (facing towards the driver's side fender). There are two vacum hoses there, check to make sure they werent switched or anything, also re-check all the vacum hoses that you disconected during the instal.

Mfanto

if they were mixed up,, would I get no boost like this?

Also check the hardpipe that bolts to the inlet of your secondary turbo housing underneath the car. If you had to loosen those bolts to get your stock y-pipe out you may have forgotten to retighten those bolts upon reassembly.

Mfanto

i checked those small hoses that are on the drivers side, and they seems to be hooked up right.

Mfanto

RCCAZ that is a good point. My freind was the one that was under the car he may have not tightened that. Do you think id loose all the pressure through there?

Mfanto

Is it possible that the Y-Pipe Itself is messed up?

Mfanto

Anyone ever had a bad Y-Pipe?

It's possible that you cut the o-ring between the halves of the y-pipe. It was there when you assembled it, right?

Or, you popped loose / pinched / broke a vacuum line in the area - CCA, for example.

PS: nobody knows 'the answer' because secondary operation and primary operation both depend on a number of parts operating correctly, and those parts have a number of hoses and solenoids controlling them. You have to look around for things out of the ordinary or do tests to narrow it down.

I put a brand new gasket in the Y-Pipe.. Thanks for the advise Im gonna go home, and trouble shoot.

Mfanto

I found the problem Last Night.. I grabed the Vacuum Diagram thanks to Dale Clark!! It was the Charge Releif Vacuum Line.. It was not connected properly. I hooked it up, and dam my car runs stronger then ever. I almost don't want to drive it, cause I want it to allways run like this

Thanks Guys!!
