Was it working correctly, and then suddenly stop working right, or did you install new stuff and then not get boost?

Have you tried putting a T in the line going to the wastegate and putting the same banjo bolt pressure on both ports of the wastegate? Overboost, or still no boost?

nick, just an idea, I have seen new turbos where the compressor nut was not torued correctley or the compressor wheel would spin on the turbo shaft. just check it out.

Heres the thing i took off the MAF and grabbed the compressor wheel and it spun very freely and no shaft play i.e.in out side to side.
Tom. I haven't tried that yet, I am going to order some new IC hoses tomorrow and some others, and hopefully that will fix the prob.

nick, try to hold the nut on the compressor wheel and spin the acual compressor wheel with your othe hand.

I'd try banjo bolt pressure on both ports -- if it (over)boosts that way, then you have isolated your problem.

Ok talked to Powerhaus today,a gave them my senario, and they said that my throttle sensor could be bad. Sometimes i can get the boost up to about 10psi, and if i try to get on it after that, it will only let me go up to about 5psi. What gives man. Does anyone think the turbo is blown.Please let me know before i set this thing on fire, For the Second time!!!

If your turbo is bad, 1) lag would be LOADS, 2) You would NOT reach stock boost (11psi).........so it should be fine.........TPS MAY be related......

Was it working correctly and then just stop working, or did you do some work and then have problems?
