D16Z6: Stock injectors max fuel pressure
I have a D16Z6 with modest upgrades: 66mm throttle body, high-flow pump, headers, exhaust. I've installed an adjustable fuel-pressure regulator and I would like to experiment with increased fuel pressure. I'm not looking for serious gains, hence I'm not interested in larger injectors and ECU tuning right now. What I want to know is how much fuel pressure can the stock injectors handle? 50psi? 60?

Re: D16Z6: Stock injectors max fuel pressure
I'm just trying to force a little more fuel into the engine. The larger throttle body has me running lean. I know that I should just put the stock TB back on so that the engine can work like it's supposed to. But I like to experiment so I would like to see if increased fuel pressure can help the injectors squirt more fuel to keep up with the extra airflow. I've gotten the impression from reading other posts on the subject that it is possible to do so. So I'm wondering can I dial the regulator up to 60psi or will that blow out a seal on the injectors?
