alright guys,
I put a block off coupler with a hole in it,on the pipe by the throttle body,
I put the air compressor gun inside the hole,
my brother put his hand over the inlet of the turbo,
we filled it up within 1 second & there were no leaks,
we had several ppl listening for one,
from the pipe to the IM to the turbo,
there are no leaks!!!

it held air very strong

pushed his hand off the turbo a couple of times

That stock BOV on the 13 is a recirculation type. I bet the plate sealed it from the outside but not the internal pathways. I know it'd be a bitch, but I'd try putting the old stock BOV on, and see what happens. I bet the air is leaking from the old BOV port back into the intake pathway.

exactly what I was thinking...just didnt know how to put it...
because the bov port is located right before the fins on the inlet side

with a hole (opening) on the charge pipe outlet (..somthing like that)

so there would be no need for the hks?

also..what do you mean by the 13?

oh I meant 13c*, that turbo you have. Yeah, if that plate didn't seal against the port coming from the outlet of the compressor housing back t the inlet that'd be my guess where the boost leak is coming from.

I'm blocking the wastegate off tomorrow,
its leaking,...so I have no choice now,
I need to take it off & see if theres a fire ring in it,..if there is..then the WG would be broke?
if there isn't I buy a fire ring...

& I plan on putting the stock bov on tomorrow...

2 things to do tomorrow....wooop woop!
