I don't think you will need any extra bracket to secure the stock IC connection point as the rubber elbow should support it just fine. That will allow for quicker removal of the assembly. Give that a try as you can always add a bracket later if need be.
Thanks for that. Yeah, about all I'm really gaining is a little less room for air volume by replacing a big chunk of magnesium in favor of a short 1" hose. Theoretically boost will build a bit quicker, not having to fill up the entire secondary manifold.

I could drop off the stock boost gauge sender (since I also have on board a separate gauge), and don't necessarily have to have the decel valve. I understand the benefit of the 965 elbow and easier access to #1 cylinder, but understand that removing the cast coupler in my case will be easy, because the BOV itself is removable from the welded-on mount by three small setscrews. Then it's just two hoseclamps and the hoses/coupler come off.

So, I'm doing this because it's the recommended thing to do, but am I really going to gain anything performance wise, other than maybe a faster actuating BOV?

If I don't like it, I'm out only $50 for the manifold I cut up and will just re-install the spare I have .
