boost leak??

[whereda40at]

i have had a boost leak problem in the past and still accures that i know of. i was taking my oil filter off and noticed 2 fittings the back of my greddy intake manifold had nothing on them. i had a shop do my rebuild and the greddy mani was one of the parts they had put on. should they be open like that, plugged or connected to something??

Looks like emissions lines for the evap.

Cap them off to see if you notice a difference. But unless you removed it then got a boost leak, I don't see it causing problems out of the blue.

my problem was that i was making boost and then it would fall off. i had people tell me that my turbo was too small for my displacement (sr2.35L stroker and a hks 2530 .86) so i ditched that and now im in the middle of putting a gt2876r .86 to make up for the larger displacement. but now im wondering if this is the real problem.

IACV coolant barbs? your not loosing boost from them, looks elsewhere?
Boostleak test it!

i might not have a boost leak then but my boost was falling off. it could have been the small turbo not moving enough air. thats why i was asking if they were the cause of it. im sure others with this mani know it more than i do.
