hey guys, i own a 1998 honda civic coupe, i was having doubts as to when the vti kicks in my car? i cant hear it .....sigh my exhast is way too loud! my previous owner installed methinks a 3.5 inch cannon, so yeah i cant hear anything? yeah are the 1996-98 models vti? a mechanic mate of mine who works for honda said my car is not vti? i got no clue...hahaha, i was under the impression all civic coupes from another thread says there all vti
vti:confused: u mean the vtec?
first, u have to check ur engine code ie D16Yx where x tells u whether it has vtec (Y8) or not (Y4)...if urs is D16Y8 then u'd hear vtec on around 6600rpm and above (i think that's the stock activation point)...if it's a D16Y4, then u'll have to imagine having a vtec:p
the earlier civic coupes (EJ8) has 2 models/ranges (i think): GLi (D16Y4 SOHC Non-VTEC) and VTi (D16Y8 SOHC VTEC)...
pls feel free to correct me if i have wrote something wrong:)
what do u mean by 3.5 inch cannon? if u think it's too loud, then change the muffler to a smaller one...
i think you're referring to vtec. vtec is a noticeable sudden boost in performance. vti is valve timing with intelligence, which kinda adjusts the valve timing to match your throttle on the fly, and is smoother, hence you shouldnt notice vti as much as you would notice vtec.
sohc-vtec is hopeless and almost unnoticeable compared to DOHC VTEC.
Just look in your books and see what engine code you have.
No, vti doesn't mean valve timing with intelligence. It just means "VTEC fuel injected".Quote:

Nah DOHC VTEC noticable performance gain, you can actually feel and hear the crossover, SOHC VTEC is baby vtec, all whine and little in gain, hear the noise but not the feel ;) If its anything like my D16Y1, you'll hear it "crossover" at around what Aaron said @ 4K.
The only Coupes available in 98 were the VTis so you "should" have Baby VTEC at the least otherwise you got smacked lol
At the end of the day, VTEC is overrated. esp on a sohc engine. so to get the most, just slap on the usual I/H/E combo, coilovers, lighteight wheels and you'll be happy for a while.
SOHC VTEC = great fuel consumption!
DOHC VTEC = what fuel consumptioBAAAAAAAAAAAAAAAAAAAAAA!!!!!
Hahahaha, funniest thing i've heard all day.Quote:

I dont know why u did just quote his whole post. Its laughable to say the least...Quote:

Complete genious you are.
You like, 12yrs old right? How does increasing duration and valve lift in any way help fuel consumption??? SOHC vtec has a secondary loab profile on the intake cam. Its a pretty simple concept actuallyYYYYYYYYYYYYYYYYYYY!!!!!Quote:

well the last vti system i saw used a sliding camshaft design with a progressive trapezoid shaped lobe. as you adjust your throttle position, it slides down to utilise the width of the base of the trapezoid to maximise valve duration.
hence it was valve timing with intelligence.
Erm... you referring to A-VTEC? :p
VTi just kicked in y0~
yeah but VTEC only effects the intake lobesQuote:

that would be a vtir
pretty daym sure coupes in that time dont come in vti
unless ur vtec fell off.....
Nope, VTi Coupe was available Pre 99 ;)
Post 99 was when VTi-R Coupe aka EM1 was brought in and the only other Coupe at that time was the GLi
facelift ftw~!
oohhh. yeah possibly your vtec DID fall off. you might want to get a mechanic to check it over for you. Might need to have it remounted with the right torque settings to get the most out of your boosting experience....Quote:

however i was serious about ur vtec falling off
LOL!!!
Its all good man hahahaha
VTEC Solenoid not plugged in properly, like someone I know lol ;)
Like you yoey. silly toyota driver hahah
Bahhhh... just cause I got some gizzmo called VVTL-i or something Geff lol (tell me I spelt it right for once XD)

Close, I'm actually 11.Quote:

In SOHC VTEC, there is enough space only for VTEC on the intake cams. So it is used to improve mixing at low RPM instead. If it had a high lift profile but kept the exhaust cam lift the same throughout the RPM range, the engine wouldn't be able to evacuate all the exhaust gases in time for the next cycle.
A Honda Civic is not an F430. Put down that bong please. :zip:Quote:

every honda driver knows this...
gettin a tad sick of all the vtec threads around. sum1 put up a sticky with big, bold letters explaining it :p
VTEC is overrated. I'll say it again. VTEC IS OVERRATED.
Unless you have an S2000 or Type R - something aggressive.
Enjoy your EJ8 for what it is. lucky you, getting a coupe. nice cars. I want...
I'm currently driving an EJ8 and vtec on this car is so soft, it doesnt seem to be there lol. When vtec engages there dont seem to be a power boost just gets a big loud...
vti just kicked in ? thats whack. :thumbdwn:
EJ8 = D16Y8 = SOHC VTEC = VTEC for shits and giggles so you can say @ the light, "Hey fellas, I've got VTEC yO!"Quote:

Nah, cut out the bottom and use your feet too, Triple VTAK + VTC dependent on your legs ;)
