How did you guys reduce to the 3 inch of the maf. I used a reducer coupler but i dont have a way to hook up the hoses from my iac and stuff. Its hooked up now but i wont idle because of the iac not being hooked up. How did you guys fab it in between the maf and the turbo?
thanks,
chris

I bought a 45° stainless elbow from Burns Stainless and welded short sections of 1" tube (for the HKS bypass valve), 3/4" (for the IAV), and 1/2" for the PCV from the valve cover. If you don't have access to a welder, I've seen people buy a NPT nipple and thread it in to the pipe directly. It's not great for flow, and you'll want to use an epoxy like JB Weld to keep it sealed.

Mine is hard to see, but you can get a little glimps at:
