3.0 L VVT-i engine from a Lexus ES series plus the TRD supercharger...how much better would that be????

Probably not worth the blood and sweat to do the swap for probably minimal gains.

vvti = drive by wire

vvti = supercharger won't work - or , at least nobody has made it work on it so far

Just to add to that: awhile ago someone posted a JDM TRD supercharger that was made for the VVTi engine. So, it does exist, but you'll have a hell of a time finding it.

got any links to that? because still haven't seen one or actually heard about it

I swear it's in either the FI forum or this one. I tried searching for it last night, but no luck.

Why it won't ?? TRD application on other model with VVT-i work pretty well with it.

From http://www.billzilla.org/vvtvtec.htm
"VVT is simple and fairly effective. It consists of only two main parts; an 'oil control solenoid' and the VVT mechanism itself."

What does the S/C would do to the VVT-i that can makes it not working properly ?

I've seen pic of the 1mz 5spA/T, yes the vvti mated with a s/c before. I'm don't think it was a kazuma s/c. - it was a JDM application .I've seen pic's at other frms before.

The article you posted did say "You are pretty much stuck with limited modifications to the engine", but I think it means there's not much you can do to gain power.

^^^

The guys his summarizing the Pros and ons of VTEC and VVT-i regarding the quote you posted. The next sentence gives me a clue.

"So, if you want an engine with power like a racing engine, then you're better off building a straight race engine right from the start"

The guys just compare racing engine with high production variable valve timing from Toyota and Honda.

But I'm tottaly sure you put boost a VVT-i engine and it will take all the gain. The VVT-i will just be more often in aggresive mode.

Interesting... I'm not sure if VVT-i makes much difference...
But if it's VVTL-i, @_@ Monster :evil:

Oh talking about this kind of technology, I can wait till all cars on the market have the Valvematic technology~~~

by **tooshorty** » Fri Mar 28, 2008 7:34 pm

ya thanks for the advice...i didn't really think it would be that great of a difference in power it would just a be a little more aggressive but not worth the effort...I wish my 'lara was VVT-i from the get go but i love her just the same without it :roll:

problem with vvti = they're all drive by wire

thus, the reason why those who have done the 3mz/1mz have to be rid of the vvti -i.e. chronoti (on TN), gabe, milt, etc.

as for vvti - it's quite helpful...a good bit of low-end power that our non-vvti 1mzfes don't have...easily .5sec of a difference in 0-60...my mom has the gen5 camry with vvti....pulls harder and also has more gears...too bad the 5speed tranny sucks though

and as for vvtLi....yeah...that'd be nice...but even honda hasn't come out with a vtec for their v6's that has variable valve technology on both the intake and exhaust side except for the nsx

You talk about a general annoying "lag" feeling problem related to drive by wire...or you refer to a problem boosting a drive by wire engine ?? If so I just cannot see the link...I need some explanations here ! :wink:

by **Eye8Pussies** » Fri Mar 28, 2008 9:04 pm

the lag from the 5-speed and the drive by wire sucks, yeah.

it's mostly in the incompatibility of the throttle set up with the supercharger- both in physical fitment and the way that the ecu controls it
