Allright childern, the cast manifold I used for my setup is from a new company, AutoBoost. Currently they only sell their products on Ebay, but they have manifolds for a about 10 or so diffrent motors. Why should you care? I'm going to be doing a group buy for the QR25DE manifolds on another fourm, $300 + shipping, if you want some more info PM me. They will work for SE-Rs, 2.5 altimas, and god only knows why but 2004+ Nissan frontiers w/ qr25de.
