I know 99' models does not come w/ vvt-i, however the other model years do. Is it possible to get vvt-i for a 99' solara?

And what doe svvt-i actually do? saves gas? more torque?

vvt-i was not available in the Solara V6 until 04.

If you want to add VVT-i, you will have to get a ES 300 ECU and engine "top" for it to function.

VVT-i allows better gas milage, a beefier torque curve and makes your engine sound meaner at certain RPMs... lol

an engine top? I'm guessing this would be like the first step?

ya... most people would have taken that as 'head' only... you need the whole top half... head... vvt-i gears, pressure sensors... etc.

Most people say the word "head" so I was just clarifying it. . . no mean for disrespect

....damn...mind as well just S/C the sucker

fa sho

yea i had brought up this question and since u cant supercharge the vvt-i i said f*uck it

can someone explain how vvt-i actually works?

yea i heard about people blowing their engine when they put super chargers on their vvt-i

VVT-i has oil pressure sensors, cam position sensors and various other sensors to monitor engine load, performance and efficiency. The ECU then calculates the best timing retardation to produce better gas mile, torque, emissions and fuel efficiency.

VVT-i CAN be supercharged and turbo charged on LOW BOOST APPLICATIONS if the ECU is reset properly. VVT-i is adaptive to the driver's habits... so if you're a feather foot and usually only hit 2500 RPM, you'll have a grip of torque... if you have a dead-weight foot, then you'll have a little more peak but less torque due to the way it's distributed. (Not a MAJOR difference, but different enough once you have F/I)

VVT-i adjusts the valve timing on the INTAKE camshaft only. Dual VVT-i (seem in the Avalon and GS 300, upcoming on the IS 250/350) has VVT-i functioning on the INTAKE and EXHAUST cams... creating a BMW-like torque curve (BMW has used Double VANOS in their 330, 5-series, etc... definately a good thing!)

VTEC, however, is not variable. It's an ON or OFF situation when the cam shafts open the valves more at high RPMs... letting the engine breathe properly, therefore, creating higher peak numbers. VVT-i was named (i for intelligence) to mock VTEC, as legend has it. LOL... i-VTEC was created but is still not variable... it simply has 2 or 3 levels instead of the previous 1... so Hondas will still have no torque... but save a little more gas =]

VVT-i should promote better gas milage, but most people still drive w/ a dead-weight foot... that's why you usually see grannys in their Camry V6 going somewhat fast if they don't know how to feather it =P Drive by wire makes it hard to feather foot it!

in other words, go buy an ITR if you are into neato exhaust sounds and going fast

yea, i asked the parts TPC manager at the toyota dealer where i got my solara about getting a supercharger and he said that toyota was placing a hold on superchargers for newer models he said that people with the x-runner tacoma (which has the vvt-i engine) and the tundra (v8) were having problems with the TRD supercharger (wich since its a toyota performance part you can put it under the waranty of your car) so toyota is putting a hold on the supercharger til they can figure out what to do about the problem.
