Looking for info on an apex rear mount setup i heard u can setup the oil return so you dont need an external pump to pump it back to engine but cant find much info online anywhere i also thought if i need to buy a pump anyway why not run a closed loop system with a custom tank underneith the turbocharger with about 2 liters of oil the pump pumps from the resivoire and feeds the turbo at the same time has anyone ever done this
