My mate has a honda civic coupe and he didnt know it was vtec until i pointed out the vtec solenoid in his engine and confirmed his engine number as d16y8 and his ej8 stamp... i redlined his car and didnt hear any vtec switchover..his car has an exhaust and i took off his cover on his filter just to be sure...cuz its sohc can you hear anything or is just not noticeable....lol my mate thought he had a gli coupe the whole time..is their something wrong with his car??
the ej8 (ek civic coupe VTI) has a sohc d16, so its NOT a vtec engine. my mate has one also, he wasnt happy with the power so upgraded to a b16a.
vti are sohc vtec
d16y8 has vtec
d16y4 no vtec
its very hard to hear vtec on SOHC motors. Mayb hook up a VTEC light LOL
err wtf? where are u getting your information from?Quote:

It is a D16Y8.
its not quite as loud as a b series crossing over.. and u wont hear it much if at all if u have an aftermarket exhaust unless its quiet as stock!
i get premature vtec
mine kicks in at 2000-3000rpm.
GG
i should call AMI nasal spray delivery.
got the same car. it isn't like a DOHC when it just starts screaming. but it is vtec and it does kick in..
had the same engine tost it for a b16a.
lol get it tune or invest in a vtec controller
dude,why didnt u tell me when i was there,i coulda checked it out.
it wont rev very smoothly all the way to redline if its not changing over & i thought i heard him winding it right out at the time.It will sort of start to loose power quite dramatically at about 6000rpm if its not working.
thats pretty funnyQuote:

yeh but i even took off the airfilter cover and everything.. i remember my mates civic vti hatch and u can hear it cross over..this is just nothing..
lol hook up a vtec light and give it another hit.
It's nothing compared to the VTi-R Vtec "kickover" sound, I wouldn't spend the cash to get the D16Y8 louder imo, lol. You want that noise get a B16A Vtec, mine sounds nice with my current exhaust and intake setup but still the B sound is such a nice note that can't be obtained on the D unfortunately
get a pod roflmao that could help u out with trying to hear it ahah. i think u should be able to hear it though =9
but yeah b16a crossover sounds so sexy. i miss it lolz
na lol nothing beats b18c+ mugen exhaust= vtec cross over!
yeeh he recently bought an AUDM integra typeR frontcut and he's plannin on installing the b18c7 into his car but yeh i was curious as to why his vtec has no crossover with the d16y8/....this is his car btw....

if he didnt change the wheels, didnt wouldnt have fell off
u sure his VTAK didnt fall off?
that seems to be a common issue
mine brother has a ej you can feel it kiks in. But nothing beat a 2.5 mugen cat back twin loop on a h22a when vtec kiks gotta love that sound. and if u add AMI spray on it rev longer, stronger and donger lol.
i hate those tailights. (same as on mine). im buying the jdm style smoked lights. he should invest there.
as people have already said~ try to hooks up the vtec light and take it for a drive, i would also check for any loose wires around the solenoid area~ and would check if there is enough oil in the car~ if its not any of that don't worry just chuck in the b18 and see what it do~
just get a microphone and loudspeaker on your car, and then when you reach around 5k rpm, as loud as you can, make a "BAHHHHHHHHHHHHHHHHHHHH" sound with your mouth into the mic.
My brother has a Civic Coupe D16y8 engine i read up on it. it has a Vtec on it. but yeah can't hear it or feel it pulling. but i do feel that after redlining it and changing to 2nd gear the car feels like it got more power(i.e it the revs are still above 4.5 grand) so im thinking the vtec kicks in a bit later.maybe...... Hey its Just a theory.:zip:
oh yet my CRX feels like it got more Vtec than the civic coupe and my engine don't suppose to have vtec it only a D16A8 (ZC) lol. it kills my brothers civic coupe.
like this yo

that is the stupidist video iv ever seen
you can hear a deeper note with my ej8 once it kicks in wouldnt say its a huge difference... tell him to get a new engine like i am haha only way to truly appreciate it ..
my D16Y8 VTEC kicks in very loud n clear... only wit a pod filter no brand @ 5500rpm... esp in 2nd gear...
I'd hook up a light just to be sure. There's a DIY about it in the DIY section. If there was a loose cable the engine light would come on when it tries to engage vtec and realises it cant or even when he just turned the car on. One of the wires to my vtec solonoid came loose one day and triggered a code 22. I checked the wiring and found the problem pretty easily. Could be an oil pressure problem or something too
same here. :)Quote:

no exhaust, but i can still hear it.
You would definitely be able to hear D16 screaming VTEC!!!!! when you have a good front headers,exhaust and basic pod filter.
Vtec change over would not be obvious with everything stock in the car.
I think you are supposed to yell "VTEC YO!". Then it kicks in?
wtf.. EJ8(civic vti coupe) is d16y8 which has sohc vtec.. What the hell are you talking about saying its not a vtec engine..lol..Quote:
