VTEC Vs VVTI ? difference ? Which is Better

Yes, u can. Buy Toyota Celica Mk 7. There is 2 version, SS1 utilised d same engine as Toyota Altis which is basically VVT-i and SS2. SS2 engine 2ZZ-GE employs VVTL-i producing 180hp. By d way, VVTL-i means variable valve timing and lift - intelligent. Under 6k RPM, only VVT-i is in operation. After that, valve lift will come into pic. D major downside of tis side of this engine is valve lift starts from 6k RPM till 8.2k RPM (electronic cut-off). U got only 2k RPM to work on.

 

D major diff wif I-VTEC is I-VTEC has SOHC VVT, whereby, 2ZZ-GE is dual VVT. So, @ low RPM, 2ZZ-GE has better torque curve. Sadly, Toyota Celica Mk 7 is EOL. So, can only buy used ka.

 

Currently, Honda has developed A-VTEC which is similar to VVTL-i.

Yup....Agreed.....Suzuki GTI & Charade Turbo....& CRX. Those good old days of small speedy car.....

 

But on the other hand....Civic Vtec has killed hundreds of young punk...rich boss son...ah beng ah seng....cos they don't know how to control those "open vtec" & crushed.

I got both cars...

vtec got pulling factor integrated.

u can feel the car sudden surge and keep pulling away..

 

vvti to me like nothing.. nothing to experience. so its just a meaningless term to me..

cant feel anything.

VTEC of course got pulling factor due to sudden increase in power on high RPM.

 

VVT-I is definely much smoother as power & torque is build up gradually as there is no sudden surge in power.

 

Meaningful or not is dependant on individual.

What do you want out of each car??? The answer will bounce back and forth depending on how you like your drive to be like.

 

I like performance and in this scenario, honda's vtec pulls it off better than toyota's vvt-i.

 

can't we have the best of both worlds

 

.... only can afford to buy one car

 

Got! Audi's LeMans racer... good FC, massive torque (and super flat curve) for pulling, and good power. [:p]

Bro, read my post carefully leh. Did I say Lotus use VVTI? I replied to the other guy saying that got other car with vvtl-i, but will cost an arm or a leg. [:|]
