I have an on3performance turbo system with a wastegate and BOV. I bought the kit 2nd hand maybe 3rd. It has the on 3 wastegate and bov. The problem im having is I dont know how to run the vacume lines. The bov has one port in top and the wastegate has one port on top and one on the side. I found some install instructions on lmr's site but they were not very detailed. Any help would be much appreciated.


Thanks in advance
Lou.

I don't have on3 but sounds like fairly standard stuff. BOV should go to manifold vacuum (near where your fuel pressure regulator connects is fine). Wastegates push open with boost pressure from the turbo housing (usually a barbed fitting threaded into the compressor (cold) side of the housing). This would connect to the side-port (top one is open to air).
