I'll be going single soon and need to either make my own or order a prebuilt kit for my Garrett TO4E.. Anybody have any recommendations where to get the lines and fittings? What is more cost effective, kit or build my own? -10AN oil return and -4AN oil feed.. Not sure what size i need for the water lines. If someone could chime in on that? This setup will be used on a 1JZ.
