Sorry if this thread is a repeat but the search server is down..we put a turbo kit on a gsr last night and everything is hooked up right and all the vaccum lines are right. all the charge pipes are good but we took the car out and the car wont go into boost. could the 5 bolt flange be a cause of no boost if its the wrong kind..thats the only thing we didnt check..please let me know if you have had a similar instance..

 

check for leaks in your charge pipes and make sure your wastegate is closed.

 

we did that and even pulled off a vaccum line to see if it would go into boost but still nothing..its a new tial wastegate as well..

 

wastegate...

 

how can i test the wastegate?

 

what is the car doing, is it running ok besides that

 

car is running i hear the turbo spool..if i rev it up i can feel air come out the bov when the throttle plate closes but when i drive it it wont go into boost..

 

Maybe you're boost gauge isnt installed properly.

 

When i first installed my tial wastegate i forgot to put this little thing in the bottom, and i wouldnt build any boost either. might wanna check that.

 

the boost guage is right it reads the correct vaccum and goes to 0 when we floor it but no boost..
"When i first installed my tial wastegate i forgot to put this little thing in the bottom, and i wouldnt build any boost either. might wanna check that".

The fire ring is in the bottom of the wastegate.

Anyone else had a problem not building boost after turbo install..?

 

check all of the intercooler piping conenctions. you have a boost leak... a big one

 

i have the same problem, when my car is ideling and i rev it up it wont go past the vaccume side on the boost gauge, i checked for leakes, couldnt find one

 

for me anyways it was a charge pipe that came loose

 

you can try to pressurize the charge pipes with a compressor or air pump (engine off). and use soapy water to trace it down.

 

I had a smiliar problem so I redid my whole charge piping setup and I found out the boots had some cracks in them, and also my boost gauge line had a kink in it.(make sure it is tapped somewhere on the intake manifold) The wastegate may be a problem with the psi it is set at as well.

the car wont build boost when there is no load on the motor. go drive it around and it will build boost

 

i had this same problem when i went to get tuned. check you downpipe, and make sure it is on tight enough. like previously stated you have a boost leak.
