is there a need for a fpr if i just get bigger injectors. I am also going to run hondata. I was thinking about running 780 with fpr, now maybe bigger and not run a fpr. Or is the fpr there for tuning. If its there for that, then wouldn't hondata take care of it.

no engine management system can control fuel pressure. you don't need it but it will aid in tuning.

You wont need an adjustable FPR if you are gonna run Hondata and run power within the means of the injectors. The FPR can help if you need to :cheat" a little and raise fuel pressure at idle to make up for smaller injectors. It all depends on your goals.

So instead of running the 780 with fpr. I can run 1000 cc and run it at a lower duty cycle. Am i right? I think this will be cheaper instead of buying two things "injectors and fpr" then just buying the bigger injectors.

how much power do you plan on making? the stock fpr can become a bottle neck. 1000cc is getting pretty extreme unless you are going to make really high numbers.
