on my ZC DOHC 1600cc
hey my turbo was fin today all plumbing done but no boosting can hear turbo whistling winning up but not any faster at all really whats the problem????

 

Check all your piping for leaks. What about wastegate it's not opening early is it? Do you have a boost gauge? Blow off valve? It's not stuck open? Check those things.

 

Are you sure all of your boost tube are connected.

 

did u add turbo fuild?

j/k i'm having the same problem.. i've narrowed it down to a leak in my intercooler.. and wornout rubber hoses.. they expand to much. check all your piping.. you really need a boost gauge if you don't have one

 

all pipes connected dont know about waste gate maybe the tube that goes from turbo to waste gate one that you put a boost tap on i had my boost gauge tee'd into that and it read nuthin.


pretty sure nuthin leaking tho

 

Drive the car (don't rev it) j/k.

Go over lines to intercooler like mentioned above. Always double check.
Check lines to boost controller and from wastegate or BOV and make sure they are connected. Most of the time the air escapes from an overlooked path.

 

yup, thought cuz everything was connected i wasn't leaking.. but i was.. i'm ordering all new pipes from JC wittney so i hope that helps.. also getting the intercooler fixed.

 

but even if it was leaking some where only a bit it should still boost up a.

 

It should boost but you never know. The air is going to take the path of least resistance which is any leak at all. You probably have multiple leaks. Were not bagging on your setup or your ability or anything but it has to be leaks. Another thing to check would be the exhaust manifold and turbo gastkets. If you've got a big leak there you wont get spool either.

 

crap **** im dumb my manifold only has like 3 nuts on it outta like 7 grrrrrr will that stop it from boosting
hey i dont have a exhaust on it either just the dump pipe only finger tight on there

 

yes it will. put the bolts on.

 

No bolts huh, lol. You might want to check out your gasket now. That much leakage could damage the gasket. Also tighten up your exhaust you need the back pressure.

 

check your vacum lines for your wastegate
