Supra-love Posted January 12, 2021 Share Posted January 12, 2021 Just wondering what size the water feed/return should be from a single turbo? Im looking to use 5/8” reinforced diameter hose. Just want to make sure this is the best size to use for turbo water feeding/returning. Water feed will come from the water pump nipple and return to the upper radiator water neck. The oil feed will be -4 and will have a 1mm restrictor following the turbos recommendation. oil return will be 10an to sump Quote Link to comment Share on other sites More sharing options...
