Did you call Corky about couplers yet? He has the prices on the web:

My setup allows me to switch the bov to the other side if necessary with a 6" piece of thin-wall steel pipe, a bov flange, and 30 seconds of welding. With this, I could rotate the bov 90* and it's a straight shot back to the intake pipe.
Some revelant info from TurboByGarrett:
"The Blow-Off valve (BOV) is a pressure relief device on the intake tract to prevent the turbo’s compressor from going into surge. The BOV should be installed between the compressor discharge and the throttle body, preferably downstream of the charge air cooler (if equipped)."
Do you think the turbo sees any difference?

I used to have some but used all of them. They are pricey, but good for heat prone areas or if you want the bling.

Makes sense to put it as close to the TB as possible as you are venting the pressurized air as the TB closes, but I don't think it makes all that much of a difference as the whole purpose of a bov is to keep the pressurized air from hitting a closed throttle plate and stalling out the compressor. If you open up a vent (bov) to air or the intake tract, essentially, you are providing a path for that pressurized air to take and it will take the path of least resistance.
Theoretically, I guess the further from the TB the bov is, the longer the pressure wave has to travel after reflecting off the throttle plate to get out, but I can't imagine it making a difference at reasonable boost levels. YMMV.

/\ That's what i'm talking about. Both sides seem definitive, then along comes an example that legitimately contradicts it. I think the most logical viewpoint is from brgracer:
"the further from the TB the bov is, the longer the pressure wave has to travel after reflecting off the throttle plate to get out"
This is what I tend to agree with, as the wave has to pass through the I/C. Although, wont the I/C slow/soften or at least disrupt the "shockwave" of air?
Either way, with a BOV somewhere in the system, I can't see the turbo being adversely affected.

(TB side here) With the BOV mounted so it points straight down on the left side, I could put a nice, easy 90* bend under the radiator hose, then it's a nice straight shot across and back into the intake pipe.

As for the T28, as long as it's rocking by 4K i'm good. FP sure knows how to make em.
I dig what BEGI is doing these days. (right behind the self torturous yet somehow rewarding way of the DIY kit.)
Have a good one dude. I have your contact info, i'll let you know.
Noah.

Today I hooked up a wastegate "spring" (a la someone here I forget who) I'm stalling on pulling and tapping the compressor housing to attach the wastegate actuator, and I managed to find this spring laying around. My actuator rod also has to be cut and re-welded at a different angle. The bracket holding the spring is the MAF bracket, so this is free until I do something about it. It feels a lot easier to extend than does my 8lb wastegate, so it might give me half that.
I was going to hook up my boost gauge from another car, but I forgot it's also a turbo timer, which has a vehicle-specific harness, which means more trouble than it's worth. I'll just buy a gauge. Oh well, wanted to see vacuum at idle as well.
