z6 mini me fuel ?s
You've probably seen this topic hundreds of times, but I can't find the answer to these ?s. I've found a lot of info on the d16a6 to d16z6 swap. People say it can be done with my stock 90 si computer. Is this true? If so, how does it compensate for extra fuel when the vtec engages? I've been told to go with bigger injectors, but I don't see how that has anything to do the high rpm fuel curve, they will still pulse like they would with out vtec.

vtec cams just have larger lobes which push u valves down farther and for longer, that causes the ecu to push more fuel in automatically and will also adjust when the o2 sensor notices the air/fuel ratio changing. u shouldnt need bigger injectors just the one that come with the head ur using.
