Engine VVT-i & dual VVT-i???

Wrong. Dual VVT-i has VVT-i on both the intake and exhaust cams. VVT-i only has it on the intake side.

bladder master's the man!

ic... u are the man... does it increase performance???

VVT-i &amp; dual VVT-i???

last yr i started wondering abt some toyota cars like Toyota Altezza RS200 hav "dual vvti" and i want to know whats the different to normal vvti

i believe they are the same but advertise differently.

i thought vvtl-i already controls the intake and exhaust cams.

delete me

correct, vvtli refers to lift of the cams (VTC) while dual vvt-i is vvti on both the exhaust and intake valves.

Nice read. I know a little bit more about my car engine.

it does, vvtl-i is dual vvt-i with lift.

I thought vvt-i was just the name of the engine....I am so lost on on what you guys are talking about....is vvt-i the computer or what exactly

vvt-i basically refers to the variable valve timing.

vvt-i is a mechanism, it's in many engines, including but not limited to the 1ZZ, 1NZ, 2NZ, 2AZ, i think 1AZ, 1MZ, 3MZ, 3UZ, etc.

this thread gives me a headache.....

vvt-i adjusts duration and overlap of the intake camshaft. dual vvt-i should be self explanatory to all but the most extreme rocket scientists we seem to harbor here at vvti.net

vvtl-i DOES NOT lift the camshaft as previously stated..... ::slaps forehead:: what it does do is switch to a second camshaft profile on the intake side that has increased lift and duration as well as still performing the normal vvt-i operation of adjusting duration.

so is it like this??? correct me if i'm wrong

VVT-i (variable valve timing w/ intelligence) only controls the timing of intake

dual VVT-i controls both the exhaust and intake valve timing but not w/ switching cam lobe

VVTL-i (variable valve timing w/ lift intelligence) controls both exhaust and intake valve opening by switching cam lobes like VTEC

lmao

so.. the supercharger for the 03... which is i think vvtl-i ..... is there a reason it will not work properly with the vvt-i in my 01???

can anyone help me out on this???? i know it won't fit under the hood.... but engine wise.... is there going to be a problem??? or how about bolting it on.. i know they make diffrent instalation kits for diff cars.. but what do you rocket scientist think? can i cut my hood and drop a TRD SC on my 01 or am i assed out on having to go turbo????

I hope someone can give me deffinate answer.. and i wish i could stil get it for that one day sale price a while back.. like 1900 or something.

help me out guys. THANKS!!!

The 03 S doesn't have vvtl-i. The only cars that have vvtl-i are the Celica GT-S, Matrix XRS, and the Corolla XRS. I'm sure the TRD supercharger will work on any 1zz-fe that has a vvt-i but u may need to fabricate a new hood and some other parts for the supercharger to fit correctly.

ok thanks.. i was thinking about the xrs then. . yeah as soon as i get cash enough i am definately gonna try to stick one on my o1

Nate- this is why I rarely come here anymore. People would learn so much more if they made the seemingly minor effort to research instead of panhandling for information. Havent been back to Auto-x either- been doing midnight mayhem mostly for my fix.

wow.. that was harsh...

If I am not mistaken.. and I know I am not cause here is the copy paste... forum is to ask questions and get answers.. thats how they work... whats your point????

Welcome to the NEW VVTi.net, This site was born due to the lack of information available for the Toyota Corolla on the Internet. This site will try to keep you up-to-date on new parts, information, mods and more about your new Corolla. Check members rides, ask questions in the forum or add parts to the parts listing. It's all for you, the Corolla owner or soon-to-be owner. Come in and check it out and register in the forums.

and we all make an effort to find answers to our question.. and this is a resource why not use it?

91DX, you are a complete ignorant moron. For the sake of goodness, raise the level of literacy here. You will never accept that you are dead wrong. Here is TOYOTA's OFFICIAL explanation about VVTL-i and it says

'At 6000 rpm a high speed cam lobe takes charge, increasing the lift duration of the exhaust and intake value allowing for a greater intake'

So much for 'VVTL-i not touching the exhaust'. Oh, but Toyota is lying and you must be right. All you seriously did was waste my time by arguing over ignorant facts.

Sorry, wrong thread. Should be in another section.

VVT-i is only phases intake camshaft timing. VVTL-i varies the timing and lift of both intake AND exhaust camshaft.

Late,
Trav

i agree

everybody just read this 10 times.. you'll get it.. eventually
