the vvt is better in the toyota than in honda.

Hehehe... I just find it funny that many toyota lovers are very biased about this argument. Vtec or VVT...

For one, vtec is far superior to vvt, and vvt-i. Simply because of its electronic lift control. VVTL-i is the cloest thing toyota has come to matching vtec. You know, if it wasn't a good thing, why are all of the auto makers implementing it in their engines?

Anyways, as for why VVTL-i isn't widely used in all of toyota's motors... because of the head design. The 2zz is the only "GE" performance head that has been designed for VVTL-i. If toyota were to decide to implement it into all of its engines, mostly "FE" head motors, they're gonna have to redesign the heads wider for the added lifters, sprockets, and other mechanisms involved. It would be nice, but impractical. The FE head, as I'm sure you all know, is a sort of cheater head, sporting DOHC running off of a single sprocket. This design is how toyota maintains the reliable fuel economy of a SOHC type narrow head design and maintain decent performance from DOHC. At least in the US, the 2ZZ and the 2JZ are the only GE motors still produced by toyota...

Perhaps if come 2005 when the Celicas are scheduled for a facelift and a mechanical upgrade, Toyota decides to bring maybe a 3ZZGE (perhaps overbored to 2.0 pushing 200+HP to compete against the RSX) or even revive the 3sge...with VVTL-i (220+HP?)... who knows... but yeah...
