i-VTEC vs VVT-i vs VANOS vs others....

Vtec is probably the best cam technology I've seen. Two cam lobes works great.
VVTI can't even be compared. VVTI just changes timing, not lift. Vtech is amazing technology that every car should have.

well, they are two totally different systems. VTEC uses camshafts with dual profiles. so when you hit higher rpm, it clicks over to the other, better breathing camshaft. helps with gas mileage, high rpm power, and emissions. VVTI, has variable valve timing with intelligence, and since i don't have a lot of time right now, basically what that equates to is better overall power. from low rpm to redline. better driveablility. anyways, go to howstuffworks.com and check it out, its a pretty informative site.

ya when i get my tc i think ill go ahead and get a vtec put on it. that should give it about 30-40whp once thats done ill get a turbo, that will add about 70 whp then ill get a blow off valve cause my friend says they give like an extra 20whp when you use them with a turbo. i might get the blow off valve before the turbo thogh just cause it makes that cool sound. by the time im done ill be running 11s all day long

When looking at V-TEC you would compare it to VVTI-L. Most V-TEC systems work on both the intake & exhaust cams while VVTI is just the intake I think. Now the real V-TEC power was the B series engines. Build up one of those engines & put a turbo. I would love to drive a B18C5 with a turbo. Just taking it up to 8,100rpm. :twisted: Have a killer exhaust on that thing also just to scare the old ppl.

Acutally VVT-i works with both the intake and exhaust cams. VVTL-i (Celica GTS tech) controls both valve timing and lift, while VVT-i just controls timing. I'm not sure if VTEC controls lift so I can't say for sure which is the better system.

How much of a difference.....
in power and economy is there between the VVTi and the VVTLi. If it would be a worthwhile transition to migrate to a VVTLi for higher end power could it be accomplished without as much hassel they're used in similar models of the same line... (i.e. corrollas use the VVTi standard but use the VVTLi in the XRS model along with a 6 spd transmission )

here's a link that explains variable valve timing and compares the differences between vvt-i, vvtl-i, vtec, i-vtec and vanos.

what a lot of people don't know is that variable valve timing was not invented by honda but toyota and gm in the early 70's. honda was the first automaker that used it in production cars.
