ok,, started to install tubular manifold ran into a prob with the bolts coming from the atp turbo hotside,,,to long and were hitting the mani tubes...after that i put the stock mani on and re used the stock gaskets so i didn't waste the new ones,,,after that there is no boost,,,stops after vacuum..i imagine there is a leak in the mani but it shouldn't drop to ) boost,,or is that possible? need some help

searched but nothin specific enough

 

start with checking all your connections this is the first place to start with a boost leak then go from there

 

goin to put the new mani on wed. atp sent me smaller bolts,,,regardless though, the hotside should still create boost even with a leak? or am i wrong with that statement

 

anybody??? lil help here

 

you would hear it if there was a problem with a gasket seal

are getting absolutely no boost or is the guage just not reading anything?

 

no boost at all

 

Definitely....I've blown two exhaust manifold gaskets and when it's leaking, you WILL know it. Not only will there be soot in the area that it's leaking, but it will sound awful and the leak will eventually get bigger. Check all your vacuum lines to make sure they're connected and free of cracks/holes then check again.

 

i'll have to do that wed i guess,,,hope its just a loose ic pipe

 

does it feel any different when you drive it?

perhaps you dropped somehting in the turbine keeping it from spinning?

 

the vacuum gets to zero but never gets into positive boost, before the mani was on i air hosed the turbine and it spun fine??

 

where is the boost guage T-ed off? If the car was not boosting, as in the turbo not spinning, you would see only vacuum... more than what you would see at idle. I had my BC T-ed at the fuel pressure regulator and it came off at the regulator nipple. I could read some vacuum but any boost reading would hit only 1 or 2 pounds even though the car was running close to normal boost pressure.

How does the car drive? Does it make any weird noises or anything? Does it pull at all?

 

if you're making absolutely no boost, not even 1-2#'s, it's more than a vacuum leak or vacuum hose routing. Your turbo is toast (I hope that's not the case), or you left a intercooler hose/pipe completely off.

Good luck with it, it's probably something with the install that when you find it, you'll be kicking yourself for all the worrying!

 

well looks like i'll find out today,,, i hope its a ic pipe which i think it is becuase the turbo was spoolin fine before the install

 

Is your wastegate stuck open maybe?

 

never thought of that but how would that even happen
