VTEC/VVTi/MIVEC tech on Mazda

[Phoenix5]

Who else wishes that Mazda came up with their own version of VTEC like Nissan,Toyota and obviously Honda.I've heard CVTCS(Nissan's version of VTEC) on my buddy's Spec V and VTEC on my other friend's GSR Integra) and it's awesome!I wish I had that in my P5

the mazda 3 2.3L engine has it... There could be other models available, but i know that this motor has it...

Man skyline, every post i see of yours gets me excited from your avatar. Sorry for that intimate moment.

[Roywhitep5]

i think miatas have vtec

 

[JCell]

Vteck just kicked in!!!!!

 

[Stormtrooper77]

The MSP's have it, it's called HESITATION.

 

[ZoomZoomH]

all the newer Mazda's have variable valve timing, only old cars like the Protege doesn't

 

[ZoomZoomH]

but Proteges do have variable length intake control!

I'm not a Honda fan so I view "VTEC" as highly overrated.

As for Toyota. My friend bought a 2002 Toyota Celica GT and the engine went at 19,000 miles. I drove the car a few times, not all that impressive.

As for Nissan, the SpecV is a nice performer. Too bad it's kinda fugly.


My .02 cents.

VTEC! s*** THAT'S FAST! NOT! Hahaha, VTEC is WAY over rated. The only way that it does any good is if you buy a $200 VTEC controller and make it kick in at lower RPM's and for a longer period of time. Drive a Prelude or a car with the H22A4 Honda engine in it and you will notice it, but any other car just sucks.

However, the SpecV is a slow car compared to others. It's no ugle I don't think but it isn't worth the MSRP price. And a Celica GT... HAHAHAHA! Funny! Your friend had to have done something to the engine to make it go at 19,000 miles. It's a Toyota, they run forever unless you're driving the car crazy which is not what it was built for. I worked at Toyota and I have had a lot of them. So, yeah...

My .02 cents ...

Mazda's tout S-VT (Not to be confused with the Ford tuning department), which stands for Sequential Valve Timing. It's featured in the newer 01+ Miatas (I'm not sure about the '99-'00), and appears on the new 2.3L and 2.0L engines as well. It will also be appearing in the new Miata's 2.0L engine, and most likely you'll see it popping up all over the place.

But hey, I like the challenge of making power, all motor, without variable anything timing. =)

the 1.8l Miada motors have vvvvvtec don't know about the others.

Personally, I think an all electronic valvetrain is the way to go. Get rid of the cams and rockers, and put a solinoid on the valve. Lift, and duration are completly controlled by the ECU. You can cruise the high way with little duration and little lift, then when you need power, the ECU keeps the valve open for maximum lift and duration.

I know Ford messed with it a few years ago, but i think the main problem they had was over coming spring pressure. or something like that...

VTEC overrated? Misrepresented maybe.

VTEC is a great design, and what would you rather have? 2.0 liter N/A with vtec or without? To put it in perspective that is a potential difference between the protege motor and s2k motor.

VTEC power!!!!!1!!! i think the only car i liked it on was my cousin's ITR. 1.8L and 200hp... gotta love that.... but his engine is so noisy, it gets annoying!

To my knowledge Mazda has never produced anything exactly like the VTEC system used by Honda. VTEC actually modifies the lift. While Mazda's system just adjusts the cam phasing, nothing to do with increased lift.

 

[flat_black]

Ayep. No lift adjustment. Just timing. Lift adjustment requires two sets of lobes, whereas variable cam timing is just introduced by pumping oil by route of a solenoid to the adjustable ends of the cam, which shifts timing in the appropriate direction.

The only mistake she made with the Celica was buying it from a shady car dealership *Hoffman Toyota*. When she brought the car in for service one of the mechanic's removed the piece that goes underneath the engine to protect it. And another time, she brought it in for a 15,000mi tune-up and they used spark plugs for a V6 Camry instead of a 4-cylinder Celica.

Sure she had some fun with it at times, it's was Celica. But she never abused it. It was an automatic for cryin out loud.

[peepsalot]

lol, i was playing a video game that had the celica in it, and it redlined at like 9k i think, is that for reals?
