feels about 5000 rpm,

 

it sounds like it kicks in a little more like 4000 on mine but i dont no the exact rpm

 

VVT-i does not kick in like v-tec does. Instead it smooths out the powerband for optimal performance, what you are experiencing is the torque peaking.

 

vvt-i is always on; never turns off

 

it just adjust the intake camshaft via oil pressure and computer sensors. making the duration long or shorter by rotating the cam shaft.

 

ya this last weekend on the dyno it felt like 4k for me

 

uhh..... just because...

umm.. no...

vvt-i is always running constantly.

 

hahahahahhaha

 

the new hondas have i-vtec so that even they are like VVT-I. Only the VVTL-I has a "kick in" RPM.

 

what car has the VVTL

 

2ZZ 1.8 engine. in a celica GTS or a lotus elise.

 

also found in the matrix xrs and corolla xrs models.

 

vvt-1
varible-valve-timing-intelligence,
self adjusting for optimal fuel economey

 

I think the VVTL should have been on the XB. I think this would have made the car more fun to drive.

 

If you can fit the 1.8L Matrix XRS motor in, then be my guest. Got to remember. This was a Japanese car to start. Least they gave us the 1.5L instead of the 1.3L that is offered in Japan. Hell some Toyotas only have a 660cc motor. How about that?

 

dont they have a bigger liter engine for the BB also.

 

1.3L or 1.5L

 

"it just adjust the intake camshaft via oil pressure and computer sensors. making the duration long or shorter by rotating the cam shaft."

Not quite. the duration, the number of degrees of rotation that the valves stay open, doesn't change, but the timing of the fixed duration cycle is altered by as much as 60 degrees, iirc...

There are engines that control both the timing and duration, but not in an xB...

 

over all its still fewer moving parts than v-tec system. more or less accomplishes the same prinicipal of effect. allowing for more power at top end and more torque in the bottom end. it also saves on some gas effiency as well.

 

I think the vvti does really good on hills. I can fill the change when going up hill.
