My newly turboed car worked fine a week ago.(and to an extent still does) I have a 93 hatch D16 w/ a Greddy Turbo kit. Everything from the kit is still at its stock settings so I should be putting getting roughly 5 psi. For the first week everything was fine. The small turbo was able to spool quickly in any gear.
Now my car doesn't want to reach 5 psi in first. Traction is not an issue right now so I'd really like the additional power that I could originally feel. I reach about 2 / 3 psi at around 4,000rpms and its stays at that low ammount all the way to 7,000. 2nd gear is able to hit 5 psi but even that is coming later in the gear than before. I can hit 5 psi around 5,200rpms.
This is really starting to bug me. I checked all the charge pipes and they are all snug and connected properly. I was told to check the vacuum lines. What does this consist of? I heard a slight wind noise from an area around the intake manifold. There is also a rapid ticking coming from around the manifold near the timing belt. Any ideas at all??? Like I said I have a small turbo so spolling in lower gear shouldn't be affected to greatly by my lack of exhaust or boost controller. It was fine a week ago. 5psi No problem. What could of changed??? Damage to turbo internals??? Anything blown up??? Im getting a little flustered Anything advice is welcome ( to a certain extent anyways ) Thanks

Your check valves may have gone bad, go to a fish store, buy new ones and replace the ones you have. Also, a vacuum line may have popped off or has an air leak. These vacuum lines could be coming off the side of your turbo to the side of your wastegate, a line from the BOV to a vacuum source, a line from your manifold to your FMU, or any other line from your manifold that goes to XXX. anyways, let us know if this helps you out.

that ticking sound is an exhaust leak either btween ur mani+turbo or turbo+dp.
