turbonetics t3/t4 trim 50 goes wrong¡¡¡¡

[elchihuas]

the past month I bought from FWD a turbonetics t3/t4 trim 50 stage 1 and it was installed on my mexican spirit R/T 2.5 turbo, but I can't get more than 7 psi of boost even when the rpm are on 5000/5500, so I decided to go to a pressure test and it was a fuk&%$n leak on the compressor housing, so I had to remove the turbo from the engine to see what's going on and...





... the turbo didn't have an o'ring or gasket

well, after that with a new gasket and all the stuff and turbo ok installed on my car, once again I cant get more than 7 psi,

**I checked pressure test ok,
**the can actuator is very very strong to move(so is not leaking for the swingvalve, even Its was revised for proper seating of the coin)
**I checked the proper seating from the exhaust flange and the turbo ok


any suggestions please

what are you using to control boost?

[elchihuas]

good question, I'm using a G-valve,

after the problem, the g-valve was disconected from the turbo and the hose closed with a plug to prevent leakings to see something wrong with the g-valve, but nothing happened, same 7 psi boost...

Did you try to remove the vacuum hose from the wastegate? See if you can get over 7psi like that. Just be very careful of the boost spike

I think he was saying he removed the g-valve and plugged the vacuum side, leaving the wastegate open.

If the wastegate line is unplugged and you're still only getting 7 psi then you probably have a boost leak somewhere (it's not likely it's a bad turbo, but checking for leaks is easy enough anyway). Double check all of your vacuum lines, your PCV system, and the intercooler/hoses for holes or anything not sealed properly.

Does your turbo have an adjustable arm on the wastegate? If so, make sure it isn't being forced open all the time by the arm being adjusted out too far.

What swing valve are you using?

Do you have an orface tube between the Y that goes to the wasegate control solenoid and the wastegate? If not this orface tube should be between the Y and the titty on the outlet side of the turbo.

yes I did it, but nothing, only once again 5-7 psi boost.

mmhh. so your point is that the swingvalve it could be leaking, actually the turbo It doesn't have adjustable arm on the wastegate turbo, but the arm it has being forced to hard to closed position because if you want to move the wastegate arm with the hand, it's very difficult to do that.

but I'm going to double check on the vac.

An used swing valve garrett 2.25 opened to 2.5" from my old garrett t2 turbo, but it working great I think ja.

in fact, I'm not using solenoid between the turbo and the wastegate, only use a

**turbo pressure hose-g valve-wastegate actuator, but at this time, it was removed the g valve to check boost and all the same.

[cawcislo]

Are you sure the wastegate door is fully covering the bypass on the turbine side? You may want to remove the wastegate and make sure it's fully closing as your pressure may be escaping through there? I'd also just grab a chunk of rad hose and run it from the turbo to the throttle body to eliminate the possiblility of a hose or intercooler leaking. Try that and see what you find.

Can we get some high quality pictures of your setup?

It has to bne some sort of wastegate issue. Im guessing its internally gated. So make sure the flapper is opening and closing all the way.

oh yes, I took to much pictures in this moment, but I'm on the job computer and It doesn't have slots for the sd memory, so I will post the pictures to night.

there's something wrong on the compressor turbo inlet isn't?, is oil.. , I will show you the photo tonight
