Is v-tec the same thing as vvt-i and what exactly does it do.

 

Here is some info on the v-tec http://auto.howstuffworks.com/question229.htm
its Variable Valve Timing

 

vtech = OLD
VVT-I = NEW

however they both do the same thing in terms of function. Its just that the VVT-I is a smart system that can determin how the driver drives and adjust accordingly.

vtech is always happening in one given way.

 

Ok, there is a whole lot of incorrect information being flung around in this post.

1. Vtec is different from VVTI being that Vtec only engages at a certain RPM--unlike VVTI which is continuous. VVTL-I found in other Toyota motors is most similar to Vtec, where two cams are involved and they have a crossover, etc. VVTI is not the same as VVTL-I.

2. VTEC is NOT ON AT ALL TIMES.

3. VTECH MAKES PHONES.

 

Here's my rant about this old topic
1. SEARCH

2. V-Tech makes Phones, not motors.

3. here is the proper info

Honda:
VTEC = Variable Valve Lift
iVTEC = Continuous Variable Valve Timing

Toyota:
VVTL-i = Variable Valve Lift
VVT-i = Continuous Variable Valve Timing

They ARE different, all four, the 1NZ-FE has VVT-i.


Hope this answers your question.

:twisted:

EDIT: JDMxB beat me to it.

 

omg lol just looked at the phone in our shop, its a V-TECH

 

VVTL-i is found in my 2ZZ-GE motor in my Celica and it is far more refined then V-TEC found in different honda motors like the B16A2, B18B, B18C1 or B18C5...

im gonna miss "Lift" at 6000 rpm's when i get my tC

 

ok Idid a lot of reseach on this frist vtec is the old version of honda engines now honda has vteci which is come on say it with me variable valve timing and electronic lift control with inteligence and toyotas vvti is the same thing as vteci but just a different name copyright laws you know thats why ford has z tec toyotas is variable valve time with intelegence

 

DUDE-- iVTEC is NOT LIKE VVTI!!!!!!!!!!

No they are not alike at all, because iVtec still features two cams with a distinct lift and crossover, the VVTI does not.

iVtec is almost the same as Vtec, which in itself is nothing like VVTI.

You guys can believe whatever you want--but i'm done with this, there is nothing equivalent to VVTI in the Honda engine architecture.

 

VVTL-i = but better than V-TEC

 

He's very right, while they both are there to help engine preformance they are very different things.

 

if you have to ask....does it really matter??? who cares!

 

ask any honda service department about vtec, they'll tell you its a joke. first off your manual says you HAVE to bring it in every 5K to get the valves adjusted, that and the pin/lever thing that engages the vtec usually breaks by about 15K and is stuck on or off. really you can't feel the ____ anyways, but then again it's not designed to be.

now vvt-i? pure genius

i love toyota

 

 

please don't tell me you are one of those outsourced workers for a dealership, seriously its almost getting as bad as hiring over seas for microsoft tech support. The employees don't know ____ about their product or competitors. I have been working with imports for a very long time, and not once have i heard a case of a pin break, and vtec being stuck on. Neither have i seen any problems with valvetrain unless someone over revs past the rev limit like an idiot.. People have gone well over 45k miles without an adjustment, and when the adjustment time comes, they aren't off by much. Drive an ls integra and then drive a gsr, not like its a 20 second difference, but im pretty sure you would say that the gsr definately is quicker then the ls... am i right? Thats basically vtec vs non vtec. Have you not driven any of the "competition" ? i know the gsr is non existant these days in the new car market, but if you talk like you do about cars, then im sure you have been in the industry as long as you act like you have. If you love toyota so much, then tell them to make a quick car please... and no honda's aren't racecars, unless built that way off the dealer. (so im not on honda's sack) But i don't see anything quick out of toyota today... and please don't answer me with saying the TC when its out...

 

now thats what I call PIMP SLAP!!!!!

 

Hooray for marketing terms!

 

No offence to anyone involved but, This thread sucks

 

in situations like this each person will think they know more than the other..

in anycase regaurdless what anybody may think or belive.. vtech and vvti are the same thing in terms of function not operation

so roll the eyes and get fired up but that's the jist of it.

 

Thank you father If you people are going to try to rag on something atleast spell it right
