ok. I have a b18b with a t3/t4 turbo, bigger fuel pump and fmu. the only work i did was to replace a crappy nissan turbo, with this t3/t4. After the upgrade the car starts and immediatly runs extreemely rich all though i have 45lbs fuel pressure. I am running check valves inline with the map senser that were there before. Before this mod, the car ran rcich. Anyone know what might have happened?
