i have a 95 gs-r and my vtec doesnt work ? i try to red line it but it wont let me. i hear the vtec kick in at 7000 rpms but it only goes to 7200 and then it stops and i cant go any farther ?? how do i make it work with out me having to buy something or do i HAVE to buy something ?

 

did you wait for your car to warm up??

 

how's your oil level?

 

do you have a check engine light?

 

check oil levels too. if the pressure isn't significant, vtec will hate u

 

gsr vtec kicks at 4400. secondary butterflys open at arounf 5750 which is what u heard but yea check your oil pressures

 

i would advise you to check the oil pressure as well, i had a similar problem 2 weeks ago, oil pump stopped working and that led to me having to change the main bearings and well as the rod bearings i should get back my integra SiR tmrw but my mechanic has advised me cause of the rebuild ill have to do some early shifting to break the engine back in...Also u guys wondering integra SiR?...yea i live in jamaica, we get the good stuff here...JDM Honda Integra SiR, ill post pics wen i get the car back

 

um..yea, i got an SiR too...

 

How would I be able to measure my oil pressure. AfterMarket Pressure gauge? Do you think an oil change will help? And I just bought it about 3 weeks ago from a small dealership....with 94k miles on it. Now would the car run normally right now even with bad oil pressure? Becuz my car runs fine but I dont feel the power I think I should from a V-Tec..

 

are you throwin any CELs?

is your oil at the fill line on the dip stick?

do you wait for your car to warm up?

 

How do you even tell if vtec is active? coz mine doesnt make any noise, i have heard though that vtec doesnt work when the engine is cold

what is CELs again..?

may be u got a smooth transition...my 97 gsr vtec kicked very smooth...with modified instake and header + exhuast piping i can barely tell the vtec at 4400, + 5400 then the rpm hand is like having boost.....well i can tell by the sound but very smooth transition

 

if u have a 97 gsr the butterflys open at 4400 and vtec is at 5800

 

wrong, stop giving false info

if you have a gsr

vtec kicks in at 4400 and secondarybutterflys not a 2nd stage of vtec nothing like that opens at 5750

here let me make it more simple

4400 - Vtec
5750 (according to Helms) - Secondary Butterflies (NOT VTEC, not a second stage of VTEC, nothing like that)

 

where can i go to check my oil presure??

 

pretty dann close to what i see from rpm meter and the sound i heard....well 4400 and 5800 then...since ur is more accurrate persay

 

Check oil pressure

 

check your computer cause my friend bought a 98 gsr from a dealership and it had an ls computer in it so it wasnt hitting vtec at all and it wouldnt reach red line

 

Check oil pressure and CELs.

CEL = Check engine lights....

As everyone else is saying ..... check oil pressure, let car warm, or check your CEL' s

 

haha that sucks.. damn shady dealers

 

haha maybe they put an LS ecu in there and there is no vtec-


wouldnt the car bog really bad around 4400 if the vtec wasnt working? thats how it was on my old civic

 

obd1 gsrs hit vtec at 4400 ,
0bd2gsrs hit at 5800

if not explain my 96 gsr with a skunk2 intake manifold( with no butterflys) hiting vtec at 5800

 

Since your not getting a CEL, and I'm guessing your oil level is fine. Since you have posted after 10 people told you to check your oil, it leads me to believe you don't have a GSR. If the car cuts out at 7,000 RPMs thats the fuel cutoff. Where does your redline on the tach start?

Open your hood, the valve cover should say DOHC
VTEC

I say this because you purchased the car from a used lot. It may have started life as a 95 GSR, but was stolen and replaced with a LS engine and still have the GSR guage cluster. Or you just have an LS and think it's a GSR.

In order for VTEC to work

-Car must be at operating temp
-Throttle position
-Car must be in gear and in motion
-Oil level/pressure

There is one more and I'm forgetting it Someone help me out.

????

No, obd2 is no different than obd1 in terms of vtec and secondary rpms. I don't know why your car does that and would need more info on it to do so.
