This is the 1st time I've heard of this! My understanding is that Honda is was the 1st manufacturer to incorporate a variable lift mechanism for the valves. Vanos is just BMW's name for variable cam timing where the phasing of the cam shafts is variable which means that they can adjust the overlap between the exhaust and intake valves. Double Vanos mean that there is variable cam timing on both intake and exhaust cams.

Vanos and Vtec are very different in operation. The Vanos system cannot vary the amount of lift of the valve, the Honda one can. And now with i-Vtec, Honda offers the variable cam phasing and variable lift. A lot of cars have variable valve timing now, even the humble BA Falcon has it. But not many have variable lift.

Vtec is definately better in my opinion. Everyone is entitled to their own opinion, even if they are wrong and think MIVEC is better! hehe :D

VTEC!!!! I just took mum's integra TypeS for a spin.. daaaaaaaamn gotta love the vtecness hehe :D:D:D

true true, doesn't Honda have something similar to this?

as far as i know MIVEC is SHIT!! i took a FTO while driving my mums Nissan Pulsar.. It was hilarious... they are higly over rated... my mate has one... and yes they are SUPPOSE to be good powered cars... Mitsubishi rated them as having 150KW engines.. though they dont seem it.. lol.. my mate ripped his up infront of me and other mates.. took it to the cut out.. it doesnt have the same roar as VTEC nor does move any where close to our Hondas... in conclusion MIVEC = SHIT!!!

the F20C is the worlds best 2L NA engine around, and it has won awards for it too. although it may have been overtaken by now, not sure though.

Every manufacturer has its good and bad engines, even honda has had its not so good engines.

I know i'll prolly get flammed for this, but i dont hate MIVEC, i have been impressed by it before, just because it doesnt sound or feel fast doesnt really mean it isnt.

^ Just my 2 cents ^

How do you guys explain that MIVEC makes more torque per litre than VTEC?


Besides, I think you guys are missing the point.
VTEC is all that Honda has...
MIVEC is just an answer to Honda from Mitsubishi.

I drive a MIVEC 6A12 Lancer, and my friend has a B16A Jap spec EG hatch.
I admit that I have more capacity etc but I have so much other crap in the car that we probably have about 200+ kg difference. The VTEC can't keep up.

And a standard MIVEC 6A12 in a Mirage did 13.7 (no interior).

Anyway, I still believe VTEC is better in some areas, but like I said Honda has been making VTEC for so long, and that is the only "performance" oriented engines they have.
If you compare Honda's best 4 cyl and 6 cylinder, I think Mitsubishi wins (4G63T, 6G72TT)

Ok guys I hope I don't get blasted here I am just expressing an opinion.

on the topic of Mitsubishi engines, whats the life-span of these MIVEC engines?

from what i know Mitsubishi engines have alot of troubles later on (besides the EVO series)

I am not really sure to be honest.
I would expect them to hold up pretty well.
I have a friend with a magna and 1.8 lancer and both have nearly 300,000km without any problems

Any pics of your car mate?

Also did you witness this 13.7 run or was it just something you heard about? The reason I ask is because I have seen 2 6A12 powered Mirage's both run high 14's. One was here in Perth and the other was over east. Both cars had good suspension and a few other mods.
