I do not know. However, I would go for it, as they can be had around $100.

The stock Honda fuel pump is pretty good. If you are staying NA I wouldn't bother, but for FI, you can't really have too much.

hmm
it depends how big your numbers are going to be then.
it'll probably take a pretty nice build to need a 255lph fuel pump though.

I would do it anyway...i'm pretty much in the same boat you are....i'm building a high compression n/a b16 as we speak and i upgraded. Its also good because then if you ever wanted to do a mini-me swap later on and really get the compression up there, you already have the pump upgrade

Your stock fuel pump should get the job done if working properly pretty much anytime as long as you do not plan on using force introduction.

There is NO WAY anyone is going to build an NA B16 that is going to require so much fuel a stock fuel pump couldn't keep up.

B16's just don't move enough air, plain and simple.

you'll be fine with the stock fuel pump for your build. and if you haven't bought the injectors yet, you're better off with 310cc injectors. If you already ordered the 450's, its still ok since you're gonna get it all tuned anyways.
