why would you want to plug the hole and run a sandwitch adaptor, that seems so backwards to me...if you run a -3 hose you shouldnt need a restrictor, but if you run -4 depending on what kind of turbo you run you will need one.its really dependent on what oil pressure is at the turbo inlet on full load on my car on full load oil pressure is at 6 bar (88psi) so i have to run a 1/32 restrictor...that sucked drilling out.
