I'm fairly new to turbos and if i built a junkyard turbo setup by gathering parts, what do i need for a complete kit. a greddy, drag, etc. kit is just too expensive. i know i need the turbo itself, external wastegate, bov, exhaust manifold, intercooler pipeing and intercooler. what else? what do i do for an intake if i'm not running an intercooler? does any turbo bolt up to the exhaust manifold. i have a d16y8 if that is necessary information. i'm planning on running 6-7 psi so an intercooler may not be necessary but break it down each way for me. where do i find the misc. stuff like oil lines, hoses, clamps, etc.? thanks for your time.
