I runny an Y7 w/Y8 head. Everything on the bottom end is stock and the head is stock with an ZEX cam. ECU is chipped w/ mugen spec. Is it necessary to have bigger injectors?

mini-mei no turbo - NO as long as they are the 240cc injectors

mini-me with turbo - better upgrade before you blow a hole in it

240's are probably good, you may want to get a adj fuel pressure regulator and pound it up a few if your running a tad lean.

Mugen spec Chip tells me you probably got it off ebay, and those chips normally lose power instead of make!

I have a P28 chipped with a mugen spec. I have a friend that has a Hondata (for GSR) that we tried using it on my car and it turn out to be about the same redline.

240cc injectors are good for 175 whp, at NA-friendly AFRs, and stock 41 psi rail pressure.

I dislike $$$ FPRs, get a second stock freebie from a friend and crush it a little in a vise until you hit desired pressure.
