- Sat Jan 05, 2013 5:31 pm #323353 if im not mistaken the d15b7 has a fuel cutoff at around 7200-7500 doesnt it, so why would you want to run you motor above factory specs....all your doing when you rev that high is putting stress on the internals, there are no power gains that i know off unless your set up to run reliably at those rpms...which since you run d15b7 i doubt you are but i dont know your setup....not trying to be mean or condecending just wondering why you would take a cheap motor with not alot of power up that high? :? i know you can reprogram an ecu to take the governor off for the speed and stuff, but i wouldnt mess with redlines or anything, mine is set up with no goverenors or anything, but i dont hang at 8200 EVER lol, i peg maybe 7000 sometimes, probably why i spun i rod bearing....in fact i think this might be a bad idea now that i think about it....but thats just my 0.02 cents,do some more research of the limits of your engine..ill try to find some more info for you too.

found some before i decided to post

Non Vtec

your absolute best bet is to leave it alone, i saw a few places say the injectors will cut out just after 7000 rpm due to the 6500 rpm redline, plus your motor wont really make power above 5500-6000 since your non vtec(im guessing the peak power is around there from the hp.tq #'s above)...and you probably have a good chunk of mileage on the motor so taking it that high is just turning it into a ticking timebomb....i dont personally see any ACTUAL benefits from it powerwise. anyone care to chime in on this, i just think this would cause alot of premature wear and stress on vital parts...again, just my 0.02 cents. hope this helps :thumb:


EDIT: just saw you were building that head, but i still dont know if your bottom end could take that abuse for very long, and if your doing that to the head, and decided to do bottom end as well, might as well build for turbo :hehe:
