Fabricated a new upper ic pipe and crushed 1g bov installed
Tossed the greddy type s after boost leaks at 25 psi and made a new custom upper IC pipe to replace the rmr one. Lost 16 inches of tubing and no more sharp bends. Thanks to fred and lod for their help....
It was an interesting experience fabbing the pipe from scratch. I ordered 3 45 degree bends from rre and the bov and we just cut and trial fit the pipe till we got it as short and direct as possible. Tig welded the pipe and the flange for the bov and tapped a hole we made to thread the aem ems temp sensor.
Lost 2 bends and a lot of length from the rmr one and it is now a nice direct shot to the intake manifold. Cost: $90 for 3 bends from RRE and the crushed 1g: Doing this was dirt cheap + works the best so far...

I will log it with the ems tomorrow. Intitial observations: No boost leak so it definitely pulls harder. Will post dyno after I finish the tune but I think if we kiilled the boost leak with the crushed 1g, it should be quite a bit stronger under the curve...

I did the same thing. I used 304SS. For the BOV (Turboxs H34), I used 1 3/4", I cut notches with a dremel, the BOV slides perfectly onto it and the set-crews lock into the notches.
And I polished them for two days.

Update: the crushed 1g bov works really well with no leak at 25 psi and it sounds really loud vta(running an aem ems)
Before, with the type s, I would have some compressor surge in 5th gear at 120+. The crushed 1g cured it.
This bov just works. The mr and the stock both share the same design except for the mounting flange but the stock being plastic sucks because it leaks and you can't crush it to raise the level of boost you can run without leaking.
I could of run a crushed mr but they are higher cost and mounting the 1g was easier the way I did.
