problems after turbo install

[ChrisFlo]

Just got my T04b install done and I have a few problems. First of all, the car will die after a few minutes of running (actually driving). This may be because the car has been sitting for almost a month... My main concern though is there is hardly any pull to the car, and when I floor it, it makes a squeak sound at one point (almost like air is escaping somewhere), and the car jerks. My idles is fine however. I checked connections, but everything seemed to be secure.

Lastly, one of the radiator fans (driver side) is not working, even though plugged in. Fuses looked good....

HELP!

Please? Anyone?

For the radiator fans try turning on the A/C then they both should be turning but under normal conditions only one is used.

I would make sure you can turn the intake turbine by hand, check for freeplay. Where did the turbo come from?

Make sure ALL hoses are tightly clamped, there is a 1" hose which if not clamped can blow off the moment you apply power but then it falls back into place and unless you look closely yout think it's installed.

Does any of that make sense?

I will give the a/c a try. The turbo is brand new from Bullseye. I applied some oil in it before starting the car. What hose are you talking about so that I know what to look for?? Thanks.

On the hose that attaches directly to the turbo there is another smaller hose about 1" inside diameter. It comes up, has an elbow, then a stagger and heads off towards the air cleaner direction. Sorry I can't remember where it goes but it can blow off as described which will cause a loss of power and maybe some noise as the pressure escapes.

Let me know if you can't figure out and I can play with some pictures to reduce so I can upload to site.

The only connections coming of the T04b turbo are the oil lines, the lower intercooler piping, and the intake inlet....right?

Yes, I believe that's correct, I don't have a manual and only doing this from memory of a couple years ago.

So do you think the leak would most likely be coming from that elbow adaptor (which is on the lower IC?)

It's not and elbow adapter, it's a molded in fitting that is part of the large hose. The smaller hose which has the elbow and then a couple bends to miss the top radiator hose near the thermostat. That is certainly a good possibility especially if there is no clamp and you are hearing an air loss. A slight tug will establishe if it's been blowing off.

Poke around and make sure all hoses are correctly installed for you can't see the forest for the trees.

I'm lost...with my turbo i bought the oil feed line and drain line, and a j-shaped adaptor so that my lower IC would hook to it. Other than this, I'm not sure I follow what connection you're talking about...

Geepers, make me jump through hoops when you could have gone out and looked.

Here is a picture.

I'd been out there all day installing my turbo, so I already knew what tubes my car had coming from the turbo, and perhaps the reason I was so confused is because that tube doesn't exist on my car.

I knew I should have gone to bed. Did you find anything by daylight or more observation which can suggest other ideas?

There is always the option of spraying carb/PCV cleaner towards intake manifold and various connections to see if the RPM changes. If it's leaking pressure then there is a good chance it will also leak vacuum at idle. Give a shot or two towards the air cleaner so you get some idea how much impact it has with the RPM.

Damn it do a boost leak test already. On a side note, the turbo is too big for your current set up. You're running a 50lb/min turbo with stock fuel pump, IC/piping, injectors...etc.

Fuel pump just got here and the rest is to come soon. I blew my t25 and couldnt afford everything at once

Just making sure you know. As for your problem, I would do a boost leak test. It's probably the or part of your problem, if not, at least you can remove it from the equation. Good luck.

They are coming out of the woodwork and I think we are loosing.

Try doing it for a living...

One of the worst things that happens to DSM owners is that no body ever tells them that they are awfully nice cars just hard to get use to. Because it's such a performer it puts an inexpensive car in the hands of a novice owner who is having trouble making payments. They sell the car at a loss, the next buyer can't afford anti-freeze but drives the car hard and abuses it till it won't run so it sits. The next person thinks they can slap a head gasket on it and it will be transportation but can't resist the $60,000 Porsche sitting next to them at the stop light to prove their prowess.

If you can't take a joke you shouldn't have bought one was how we use to describe the Datsun 1600 roadster. Of the 10's of thousands of those cars I now see 1 a year, so will be the path of the DSM if people don't start taking care of them.

Wow well said

Yeah definitley sounds like a boost leak.

 

[ChrisFlo]

Okay, it was a leak in the lower intercooler piping, and its because I had to ghetto rig it with couplers in order to get that piping to fit the t04b (lower radiator hose in way). Is there a particular intercooler pipe that will fit better with this turbo for the stock sidemount?
