Engine VVTi and dual VVTi

VVTi and dual VVTi

What is the main difference between VVTi and dual VVTi ? How does it differ from iVTEC ?

what car has the dual vvti engine?

And the new V6 camry and IS350 engine has dual vvti too.

Beams 3S-GE in Altezza also dual VVT-i (210 hp)

the vvtl-i (2zzge) has both the exaust and intake valve lift very similar to the vtech, although dont be confuse the vtech has a totaly different way to engage and is totally different programmed in the computer

Vtech!!!

Dual VVT-i engines: 2GR-FSE, 2GR-FE, 3GR-FE, 3GR-FSE, 4GR-FSE, and 3S-GE

Do you guys think anyone of these dual vvti engines would fit in a 97 corolla?

the 3S-GE and 3S-GTE can but needs custom mounts i think..

the 3sgte never came with any form of vvt-i.

It's not Dual vvti it's VVTI-L varible vavle timing with Intelligence and Lift. they only make it in the 2zz engine, the altezza or IS300 only has VVT I. Currently only the celica GT S and Corolla/Matrix XRS have VVTI L

negative. if you read the above posts, dual vvt-i is where both intake and exhaust cams are equipped with vvt-i. on the 1zz-fe motor, only the intake cam has vvt-i.

you are referring to vvtl-i, not vvti-l. however, you are correct that it also incorporates lift.

can u all help me who know the toyota estima timing markking 2400cc vvti enjin pls????????

msn me!!!! my email is lwf83@streamyx.com this also is my msn email

the car is malaysia car toyota estima 2400cc vvti enjin pls help me 10q to u all
i already 2day not sleep loh pls help me

Sorry that was a type error It should be vvtl I

so whats mods do you suggest for the 1zzfe vvti motor to reach 190bhp?

i have to correct jspitz, there is a such thing as a dohc vvt-i in a corolla and i know that for a fact because i am a toyota mechanic,and yes the dohc vvt-i would fit in an older corolla you may just have to change the mounts. The dohc vvti and the dohc vvtli motors are actually stronger than the vtec honda motor, the vvti motor when mod. correctly can put out 190bhp without turbo or supercharger, the vvtl-i can actually put out 205-210bhp when mod. correctly without turbo or supercharger also.

for older corollas, like the ae92 or ae101, a nice engine would be the 4AGE silvertop or blacktop engines...

for ae101's, the silvertop is a bolt on... no modifications in mounting...

hey dtownrolla if you do a racing header, full exhaust from header back and use a full cold air intake you will come up with 190 for the vvt-i motor

Huh?!

With the supercharged 1ZZ-FE, you're looking at around 180 crank hp. How would just intake and exhaust net a 60-70hp gain on the 1ZZ??? I'd rather think that FI or nitrous would be required for that kind of gains.

I am just wondering does vvti sound anything like vtec? It is possible to put a 2zz head on a 1zz bottom end??

I am just going to stray off the topic a little bit. What is the difference between the '02 celica engine and the '02 corolla engine. Why such a difference in hp numbers.

Or there's the possibility that Toyota has under-stated the Corolla's hp/tq. numbers for marketing purposes. On my '03 Corolla, I dyno'ed before the s/c'er and after the s/c'er. Before the s/c'er was installed, I dynoed 122 WHP and 115 ft-lbs. Being a 5-spd, if we say a 15% loss through the drivetrain, then that would put me at around 143 crank hp, and 135 crank ft-lbs. Now, this was with NO MODS other than a magnaflow muffler, a stainless-steel oil filter. Everything else was 100% OEM. After the s/c'er (which advertises 166hp and 145ft-lbs @ the crank), I laid down 160hp and 150 ft-lbs TO THE WHEELS. Again, stock intake and no other supporting mods other than the muffler and oil filter. That would mean I was around 173crank hp and 170ft-lbs at the crank. SAE correction made a difference of around 2hp and 2ft-lbs. The engine just simply does much better than Toyota and TRD advertise in terms of power.
