Hi,

what do you do with your vaccuum connections on a B16 Engine?

on the setup i buyed there were several connections open to atmosphere and not connected like it was before the turbo was installed.

i.e. the vacuum line from the throttle body to the charcoal canister is not connected anymore...

is it possible that this is the reason why i fail the emission test?

in general: did you change anything on your vacuum lines when you install a turbo?

Thanks
Malte.

 

From a visible standpoint it should make you fail emissions (like here in Oregon) as they check you vacuum line routing... On the other hand, it shouldn't affect how the motor is running so if the motor is fine and they don't do a visual inspection too then you should pass... On any car I work on (besides customers) whether we be putting in an NA or FI motor I like to pull the charcoal canister and stuff out (putting it back in later if they need to pass emissions)... That's just me tho because I like a super clean engine bay... As long as there are no vacuum leaks, etc. to the manifold it shouldn't really make a difference... There is one other side to all of this... If you car happens to be OBDII and you completely remove the EVAP purge solenoid, you'll first have a CEL and second you shouldn't pass when they plug in a scan tool... Hope this helps a little...

The canister has at two connections (OBDI)... one is the vacuum signal (goes to IM), the other is the vapor line (goes to before TB). Neither of these effect anything other than keeping your fuel tank from leaking gas vaoprs (maybe some fuel mileage)

The poepl who did the test should tell you why you failed- look on the slip you got.

No, you don't need to, although many people add lines for boost gauges, blow off valve, etc.
