Re: Kinugawa oil/water lines
Advice - don’t run a restrictor.
New modern built race engine are running higher pressure (oil pump mod and relief valve mod in the case of a 3sgte), in that application they need a restrictor on the oil feed to the turbo (not drain). Do not create the restriction pressure in the turbo by restricting the drain.
Having had kinigawa stuff before, and things not fitting properly being a mr2 (not a ct turbo in a Hilux or gt4), they were good to deal with and get a resolution. Check the listing is for mr2 specifically, email them questioning if it fits mr2, then if it doesn’t you have something to go back with.
