I am trying to replace the stock pipe with aluminum piping for the turbo installation. What piece do I need for the pipe closest to the throttle body? It looks like there are a couple of hoses connected, and I am not sure which ones I need and which ones I don't. The piece of piping I have doesn't have any barbs or anything to hook them up. Are they all necessary? Is there somewhere I can buy one premade? I have a MegaSquirt installed if that matters. Probably a stupid question, but I can't seem to find anything about it.

Thanks!

 

you at least need one barb on it so the idle valve is attached. otherwise, the only other thing attached is just a resonance chamber.
