Spool Turbo Installed: HELP!

[igdrasil]

People...WHOAAAH, this car is pulling like crazy. But: I NEED SERIOUS HELP:

1. Its Overboosting....SOLVED
2. Turbo is leaking...SOLVED
3. Blowoff is not opening!...SOLVED

4. Idle is ok, The rest is running ok!

What wastegate are you running? About the only way you are going to boost that much is if the wastegate is stuck closed. Even if hooked up backwards the Tial only boosts up to about 9.

Unless you got ahold of a wastegate with a 20 lb spring in it, then yeah it would boost that high.

How Am I suposed to run the vacumm to the wastegate (turbonetics)?
I will show pics of the vacumm lines, maybe Im an asshole and ran those lines wrong?
Right now im taking the vacum from the turbo outlet, directly to the BlowOff, wastegate and FMU

leaking!

heres the pic of my leaking

The BOV, boost gauge and FMU should be tied into the manifold, not the turbo.

The deltagate should have 2 ports, one on top and one on the side. The one on top should be plugged up with a plug and a nut around it. If you loosen the nut and turn the plug it will change the boost.

The one on the side should be running to the compressor. Does yours have a sticker on it with a number? If so that is the spring you have.

So oil is leaking from between the downpipe and turbo? If so then you have a bad turbo, the seals inside are leaking. Or you may be running too much oil pressure.

The pic of the turbo, is that from under the car? If so it looks like the oil feed line is going into the bottom, if so your turbo is upside down and would explain the oil leak.

thanx for your reply

The turbonetics says ( 6) in a sticker, it is supposed to be preset to 6psi from spool. I WAS running the wastegate, blowoff and FMU from the outlet in the compressor, and the boost gauge from the manifold where the cruise control takes the vacumm.

everything is fixed

Yes the the oil feeds from bottom and goes up to the oil pan return line

 

[NC_MP3]

The BOV has to be hooked to the manifold, it has to see both vaccume and pressure. I guess the FMU is OK on the compressor, but I would just hook everything to the manifold.

 

[NC_MP3]

So that line in that pis IS the oil feed line from the bottom? If so that is your problem. The oil feed is pressurized, but the return is gravity fed. The feed MUST be on top and the return on the bottom. You can loosen the bolts that hold the center section to the turbine and compressor and rotate the center section.

 

[NC_MP3]

Or you may have just hooked the feed where the return should have been. I don't think it matters which one is used for the return and for the feed, but that is one thing I have never thought about.

Thanx I will do that and run again the vacumm lines on monday.

Then again!

The call pulls like crazy...it even blew one intercooler pipe!!!!

 

[NC_MP3]

It may pull hard, but 20 psi and a backwards oil line is really not good. I would also talk to Terry before you do anything.

It may be...but, if i hook the return line on the other side, I will not be able to hook the feed, it just dont fit. No way to screw it, its a big square. check the pic...thats the return!

 

[NC_MP3]

OK then yes, you need to rotate the center section so that square section points down. The feed line is the round hole, the fitting just screws into it. The return is the square and should have a fitting that bolts to it.

The return must be on bottom. That explains your leak and smoking. Oil is being sent to the turbo but has no where to go and is sitting there and burning. I would not run it until that is fixed.

 

[igdrasil]

Thanx for the tips. I would never imagine that could be a problem, but visualizing, what you saying is very logical because i Had to rotate the compressor to make it fit on the intercooler pipe.

Could this be the problem that Little Beavis have?
-Hes running the same problem, hes looking for a restrictor or something...but i dont know how his turbo is hooked up.
I will stop the car, im scared, I just test drove it to watch for leaks

Did only a 15min drive towards home and boosted it like 6 times.

 

[falkofire]

at what rpm were u hitting boost? ( what rpm did the turbo spool at?)

Trust me, too soon! very soon on the rpm, 3k rpm im already boosting HARD!

Yup, mine was sent to me like that too, but I caught it before i installed it.

No, they have different sized flanges. Both sides of the turbo have to be clocked to essentially rotate the center housing.
