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...

i haf a ST wif A series of engine (c2piG toy put a FE in it!)... i'm not goin 2 do a buy n sell thing kind of stuff coz involved hell lot of $$$ & ¢¢¢...

my intention is 2 get away of the c2piG FE engine 1st & replace it with 3S-GE... preferrable wif vvt-i...

it is really clear tat red top is intake vvt-i n black is dual... if i wanna swap my c2Pig engine with 3S-GE beam dual vvt-i, will the gear box coupling fit?! how about the engine mounting coz it is a RWD engine??? otherz standard 3S engine (regardless it is a FE or GE or GTE...) partz like intake manifold, timing belt bearing n etc fit in? what other necessary need 2 b taking care of especially the engine is from RWD transplant over 2 a FWD? will my original gearbox able 2 stand the extra torque / power?!

4 the conversion of ST -> GT4... haf 2 wait till the tranny done 1st...

thankz guyz... ;-)
