confusion... 3S-GE vvt-i, dual vvt-i? single vvt-i? Options

[kanazai2001]

hi~ i'm a newbie here... and i'm having a ST model... im apologized 1st if my c2PiGz Q annoying anyone here...

i would like to swap my stock engine with 3S, but i'm kind of confuse regarding the 3S-GE vvt-i thing... i got the bottom info from a japan website:

"DUAL VVT-i which also the control of the exhaust valve is done tempering 4 cylinder sport twin cams which were lifted, in addition to the BEAMS (Breakthrough Engine with A Mechanism System) 3S-GE DUAL VVT-i former inhalation valve, (Variable Valve Timing-intelligent) it loads. According to engine rpm and accelerator opening, because the computer optimizes the opening and closing timing of the inhalation and exhalation of air valve continually, inhalation and exhalation of air efficiency improves furthermore over entire area, raises output torque. "

it is the red top 3S-GE vvt-i a DUAL vvt-i?

furthermore i would like to convert my ST to GT4... is GT4 a FULL TIME 4WD or manually selectable or auto engage during wheels slide?

thankz...

thanks kwanz... sorry 4 the bad english as well...

i'm not doing the swap but the workshop. they have done an excellent job of swapping my merc 8 valves engine to a multi-valves and manual gearbox to auto. i think it should be ok on the wiring.

i have asked about the toyota altezza front clip without gearbox, it costs around US$2k. thus i would like to know any other parts that i need to get before doing the swap. for the intake manifold, shall i turn it 180° or get it from the FWD 3S engine?

thanks for the help. hope you guys can understand my bad english.

You can get an altezza front clip for 2k!? that's unbelieveable... that's cheaper than a lot of 3SGTE front clips... 8-O

No... you cannot simply turn the intake manifold around. It'll have to be cut/welded or you're gonna have to research and see if the redtop intake manifold bolts up. The non-VVTi intake manifolds will most likely not work.

Seriously though... unless you can get diagrams for the BEAMS engines... wiring will be a nightmare. Later model ECUs need a lot of signals before they'll fire up the motor... and as far as I know... not many people have wiring information on the BEAMS engines... hell, there isn't even a lot of documentation on the 3rd gen 3SGEs... let alone the BEAMS.

For the 3rd gen 3S-GE is pretty easy. First 3 ECU plugs you don't mess with, only the last one. And to figure out what wire does what, open up the ECU and the pinouts are there. On the BEAMS, the pinouts aren't on the ECU. For BEAMS wiring help, I suggest you talk to first4age at MR2OC.com.
