Let me start with the engine im working with (F23) i know some of u right now are probably wondering why i even bothered but i had my reasons. So basically i have a kit for it and decided to also build up the engine and do as much as i could do so i resleeved pistons rods port polish aem ems rc injectors aem uego cluth fly wheel. So heres the problem when i take it to the dyno i get the problem of low oil flow to the engine for the car to kick into vtec.
This is what we have tried checked the block reopened everything changed the oil pressure regulator changed that. Now i dont know what could be wrong we are assuming the turbo is drawing too much oil but dont know what to do.
please help
