H22a RPM ranges? - Honda Prelude Forum

dj_wawa · 12-24-2002, 02:14 AM

I have a simple question that breaks down like this;

what RPM does the Vtec engine idle at (stock)
what RPM is the Vtec crossover point
what RPM is the fuel cutoff/rev limiter

and any other important points I may have missed

and if you have a few spare moments why not list the stats for the S and Si motors (as well as JDM if it's any different)

thank you so much in advance

for the h22a4:

idle: 700
crossover: 5200 (i think)
rev limiter: 7400

I'm an idiot...i swear i thought this was in the 5th gen forum....oh well, at least now ya'll know what the 5th gen usdm motor has...

dj_wawa · 12-24-2002, 02:29 AM

same engine is it not?

huge thanks either way man, it's 4:30 am and I didn't expect a reply anytime soon

h22a = jdm spec, SHOULD be the same stuff, but you never know what those crazy japanese save for themselvs

actually the h22a4's can be pushed to 8000!!!! the 7400 redline is just a percaution!!!

Idle should be anywhere from 500RPM to 840RPM depending if you have your headlights on, A/C on and stuff like that
VTEC crossover is at 4900RPM
Redline is at 7400RPM
Rev limiter is at 7600RPM

I just checked in my 93 Helm for those numbers. Though I haven't found the redline and rev limiter numbers today I'm sure they are right

I am almost positive that is correct. I think though whenever someone asks for specific specs people should not reply with their estimates. A H22 cannot hit 8000RPM with a regular P13.

Very Close to my JDM.

Idle: 600-700 static (Nothing on), 800-950 with lights/AC etc.
VTEC: 5200 (when you feel it) but with a light, it actaully comes it just on 5000rpm.
Redline: 7400rpm
Cutoff: 8000rpm (checked with a Digital Tachometer with readback as well as on a Dyno Computer).

actually, the 7400/7600 redline is correct, it is just that our tachs are off at the higher end of the revs. Take a look at when rev limiter hits with a vafc, and you'll see

4900? is that only for 93's? i could've swore that my stock vtec was at 5200. (but then, i've since changed it to 4700, so i'm not too sure anymore where stock xover was)

i do agree with the revlimiter and x-over

yeah the tach is way off, if youre looking at it at 8 its really mid 7's

what ecu are you using, i have had a 96 OBDII p13 and a JDM P13, and both cutoff nearly the same if not exactly the same

Except your car, which does something up in the 9500 range

[SUB[EX] · 12-26-2002, 10:03 PM

Thats my car that cuts off at 9500.
Freaky Mugen Program.
I guess thats why i keep breaking it tho. Always a new problem.
One suggestion, if you have a BAD Axel dont drive on it. Half the bolts on my suspension vibrated loose, also my oil drain plug and unfortunately my flywheel bolts. What a pain in the butt.
Im currently waiting on a new set of FLywheel bolts from HONDA(i h8 buying from honda)

X01VTEC · 01-01-2003, 10:51 AM

well malken is talking about my car too, the old motor i used to have with the skunk ecu
