No boost no leaks...
 

I have a problem with my turbo (I think). I have ZC VTEC and it is I/C & turbocharged. I cannot boost at all. I have checked for leaks (and found zero); I have replaced the wastegate (and the problem persist); I took the turbo off and had it inspected at Turbo City in Anaheim and the turbo is fine and it does not leak oil nor does it have any shaft play. So what can be wrong? Does anyone have any suggestions or similar problems? Thanks

One of three things are broken, even though you say they aren't.

1. Boost leak. Check all couplers thoroughly.
2. Wastegate. Could be stuck open, depending on how it's mounted. Internal or external?
3. Turbo's fucked.

4. Leaky BOV

Ahh yes, that too. Make sure it is closing under boost. Where's your vaccuum source for it?

(5.) exaust is to restrictive to let the turbo spooled up proper like.

Nah, even with stock exhaust it will still produce boost. Even with a clogged cat he should get a few psi.

I removed the BOV pipe and replaced it with a new pipe. So no BOV at this time. I have stock cat with Tanabe exhaust system. All couplers were checked and they are all fine. The turbo has internal wg but I already tried running it with the wg disconnected and also the vacuum line from turbo to wg disconnected but it does not spike or even produce boost.

Well if your wastegate is disconnected you definitely won't boost, your flapper will just flap open all the time and your exhaust gasses will bypass the turbo. Check this:

With your wastegate hooked up and your car off, is your flapper closed? Feel it with your hand, it shouldn't open unless you pull on it a good amount. If it opens up very easily then your wastegate is probably faulty.

can you post pics of the set up?

silly answer but true.

are you running the car or just reving it?
also, what boost controller you using?
