i am posting this thread up for a friend..he has a 93 civic with a ls/vtec and a full turbo kit setup..for some reason there is no spooling comin out of the turbo,,the boost gauge goes only to 0 and thats it.we have checked all the pipping and couplers and they seem all fine.all the vacuum hoses are fine 2..what else can our problem be??

 

What turbo is it? Could it be that the turbo crapped out and/or broke the shaft? Does the wastegate open? Give us some more detail on the setup, and the setup of the turbo and we'll go from there.

 

Do you hear the turbo spool at all?

I bet you have a freaken leak. Re-tighten ALL of the clamps. You may even consider using some of those 3M adhevises between the rubber hosings and the piping to ensure a tight seal.

 

what kind of wastegate

are there exhaust leaks

double check piping and couplers

 

pipping and couples were all double and triple checked for leaks,the wastegate is tial and the turbo is turbonetics,,he said that he had the turbo on his other engine and the turbo worked fine but the motor blew..you can hear the turbo whining but no spool .there is absolutely no shaft play at all..the downpipe is not connected and is the only thing not connected..we even changed the vacuum lines on the wastegate 2 the 2 different positions and still nothing..

 

does he have the fire ring in the wg?

is exhaust coming out the dump

 

i know that he does have the ring in the wastegate and the wastegate is staying closed he says.

 

can you spin the impeller with your finger?

 

Lol...he "says" the fire ring is installed? Why don't you open it up man and double check, also make sure its installed properly.

Try revving the car and feel with your hand if you can feel exhaust coming out of the dump tube.

And also as stated above, spin the wheels (fins) and make sure they turn together and that the shaft isn't broken. Does it spin freely when you spin it? If not, maybe the turbo is shot and its not being allowed to spin fast enough to make boost...

If its none of what I just said, you just have a leak somewhere and your missing it.

Edit: You didn't leave any rags in the turbo manifold did you? haha...not being a dick...people do that ****.

 

Are you trying to get it spool by revving it or are you driving it with load on the engine?

 

Good point. It needs to have some load.

 

we were driving the car ,,,,and we figuered out what it was...all the bolts for some stupid reason were loose on the turbo and i think he said that the seal inside wasnt on right..mind u that he had the turbo rebuilt str8 from turbonetics

 

they may have left them loose so you can clock it. also you need to put the downpipe on, you are gonna melt something or start a fire with no dp connected
