ok so just bought a gt35r turbo for my evo8. im gonna fabricate everything, but i just have one problem. the oil supply is very confusing to me. do i get the fitting that is restricted (atp turbo fitting) or not? also what size line? -3an or -4 an? im getting frustrated as hell. something so simple is so hard to find online. so can someone please give me a hand? lol. the top of the turbo, where the oil goes in has a wierd style inlet. and it doesnt look familiar to me and i cant find anywhere online where to get a fitting to match.
