I can only get a 8-5-8 boost pattern. I have tried everything I can think of.

I am attempting my second hose job now.. with all new silicone hose. I was wondering if a cracked manifold would cause this? I have the Y-pipe, Apexi FMIC, and Apexi Power FC, I also have had my turbos rebuilt.

The other thing I was wondering was when I reinstalled the turbos. I was able to turn the housings. Is this normal? I am assuming it is, so you can align the outlets.

Any Ideas?

Thanks.

turn the housings??? never heard of that one before, you can turn the y-pipe to align the outlets...might want to get that one checked out

 

turning the housings is called "clocking" and it is possible with stock turbos. you did tighten them up right?

sounds like a boost leak to me, since you are getting the same pressure before and after the transition.

 

the turbo center section and cold side needs to be clocked in .The center sections gets tightened with 6 bolts each ebsure they are tight, the cold side has a big snap ring if loose will let you clock ti in position. Be sure the ring is seated in its grove.

 

Explain clocked in? The side with the snap ring did not totally lock in place but the ring is in its groove. I figured that the rest of the secure points would keep it in place. Would this affect the boost?
