did a search but didnt find an answer on what parts and components are neccesary to safely rev past the stock redline .. other than valvetrain i mean. and ya i know that the h22a peaks at like 7500 hehe. i just want to be able to rev higher

also what do retainters and valve springs do? lol

 

the h22 peaks at like 7000....6800 on a 4th gen motor...

 

Do you mean how do you bypass the revlimiter or how do you build a motor so its safe to rev higher?

 

how can i build it to rev higher

 

well, if you build the motor to be able to rev higher, that doesn't necessarily mean you're going to get more power. each motor has it's max torque at a certain rpm thus you might lose power by increasing rpm.

 

drop in a B-series

LOL good idea

 

You might lose power by increasing RPM but by winding out the gear it place you up higher in the powerband after you shift which is beneficial to VTEC motors since there powerband is usually high on the tach... In my case, if I do not rev to a certain height I will fall out of VTEC(luckily it lands right in my torque powerband and then quickly goes back into VTEC) but something like that can easily be fixed with a VTEC controller and some dyno time... There are many people say that there is no reason to rev a motor beyond its powerband but I disagree....

 

to build your motor to rev higher you need head work. You need cams that make power to where you want to go. highest ive seen for a h22 i think is 9. of course you need complete valvetrain upgrade (retainers, springs, vavles if necessary). i would also advise in spending the extra money for a port and polish job.
you need to then have your ecu flashed or if you are OBD2 get an OBD1 ECU and harness and have some sort of engine management in place otherwise you will be running rich as all hell, or lean when you rev it out to 8500 or what have you. Ive done some researching and i think Hondata is the best for this as you can get just about any OBD1 ecu and have it remapped and tuned to your car. I would recommend a p72 so you still have your secondaries.

the powerband on a stock 5th gen ends at 7300. after that your in the red and not making anymore power.

You get what you pay for in terms of internal parts. spend a little bit extra, get a better quality part and be happy.

how many rpms do you need? 500-600 above peak is enough and you get it stock...it's enough to stay in VTEC...

You could always destroke it to like a 2.0, build up the internals, and rev the **** out of it.... you'd loose alot of torque and might suck for the street in a 3000 lb car though

 

My boy's neighbor's best friend revs his to like 10k all the time. Makes mad power. Don't believe the hype, go for it on a stock valvetrain.

 

It's only in 2nd gear really... When I first started driving with this motor I would rev in between 6800 and 7200 I would fall out of VTEC... but now I shift at atleast 7500 and I stay in VTEC even in 2nd gear... I think it is because of the gearing differences in the h23 and h22 tranny...

 

Some parts that you will need to rev any higher than the rev limiter is:
cams
cam gears(not needed, but better)
valves
springs
retainers

That is most of the top end and will help you to rev higher without worrying to much about floating a valve or some other problems. You still shouldnt rev to high unless you drop a b series motor in like other people have been saying.

 

lol they were being sarcastic, if you drop a b series in a lude, i will laugh at you until the end of time.

wow.. uhmmm

The head would have to flow better
So would the IM and runners
Forged internals
and lets not forget ... TUNING

 

coooolio, thanks alot guys. knowledge is power ! hehe

 

nah reving higher is power....

 

I have a 95 vtec, I have a chippable jdm p13 to extend the rev limiter, I use a msd shift light(that uses the "pills")and the motor is internally stock.I noticed a drop in power around 7200, but after I installed a msd 6al i gn box(with rev limiter)the power doesn't drop until about 7900. Right now Ihave the rev limiter set at 8200 and I shift at 8000. According to SKUNK2, the stock engine is good for about 8500 with no problems(valve springs 8500 MAX)

 

^^what motor? B16?

ummm yeeahhhh...

An MSD ignition box caused your peak power to go up to 7900 rpms.


yeah...

 

^^^LOL. What motor are you talking about? Its seems like your talking about the Sohc? Cause i know b16 max power is around 8000.

 

I did not mean that the power went up, what i meant was that I did not notice the power drop off as fast over 7200 with the msd ign versus the stock ignition. Maybe the msd is capable of maintaining more spark energy at high rpms, I couldn't tell you exactly. I do have other mods, maybe those are contributing, but I do not feel a significant power drop until just as the shift light comes on.

I have 95 prelude VTEC with h22

what about your crank and bearings. how the hell is your stock crank gonna take 9000?
