OEM Honda Injectors from b18a1 to b18c5 I believe all have the same cc specs. So, my question is at what cc’s do they peak at with stock settings. Reason is, how much can a FPR possibly do if the injectors or fuelrail are the bottleneck? Curious if it’s worth the money for an LS setup.
I am not sure of factory honda specs on fuel injectors, and am not sure you will ever find that kind of info. Injectors are not messured in cc’s, they are measured in pounds per hour flow rate or “lb/hr” If you are going to turn up the fuel pressure by adding a pump, or a fpr, you also need four injectors that flow more lb/hr to accept the pressure. aftermarket injectors for the b series engine are all over! Hope that helps…
