4G91 Gang..

[cpmah]

cpmah... crank pulley install aredy ha... how the performance wit it...

yr mech after put in SGTI TB got tune back or not....

Just get back from my friend for doing the coating & cleaning, going to install this weekend. will let you know the result.


my mech got tune to max liao, like what wirafly say, maybe need some experience guy who did it b4 one.

If not mistaken one of the forumer here having the same problem when installing 4G93TB, you need an experience workshop to adjust the TPS (Throttle Position Sensor) position by the help of MUT device, or else u will face high idling speed even though you max close the screw for idling.

wirafly,
Ya, my mech install everything into my car, that mean the 4G93 TB with it TPS & ISC. So what should I do? need to use back the 4G91 stuff or not? or you have any recommended mechanic?

Just want to verify something, i bought the zenden extractor yesterday. Then today i went to the exhaust shop and the mechanic quoted me RM170 for installing it.

According to him, he say my stock 4G91 already has a 4-2-1 extractor. Is this true that a stock 4G91 has a 4-2-1 extractor? I looked at it and i thought its a 4-1...:Not_Impressed: So he ask why am i installing something that i already have...i was speechless.

I just want to clarify this, does the stock 4G91 comes with a 4-2-1 extractor? If yes then might as well i just upgrade the air intake.

yes, 4G91 come with 421 extractor but it primary and secondary is must shorther than after market extractor, install or not install is actually up to you, but RM170 installation is fucking high...just go to wei yip ask install...

[greatharold]

WAH... 150hp on a 4G91 huh?? Hahaha.... thats difficult to get... assuming if u're not going to turbo it... u're looking at spending at around RM10-15k for 150hp on engine... if u want on wheel... maybe RM15-20k la. =Þ

ITs not easy to squeeze power out of an n/a powerplant.... unless of course u up its displacement...

If u turbo... u're looking to spend about 5k minimum... then u'd probably get 150hp on wheels or more of u're lucky... depending on ur setup.

Yup is true that 4g91 comes with 4-2-1 extractor. But then, I believe that the zenden 4-2-1 extractor have different inlet dimension from 4g91. Bigger that the stock one. U will feel more pickup if not mistaken...u can ask skyline_maniac. he is using zenden extractor.

aiyoh 170 is really 'cut throat man.... dun go there, then come back home no kepala aredy....hehehe.....maybe the exhaust fucker whos nuts abt 4-2-1 xtactors lar.... c also can knoe the difference... aftermarket has different length for better performance as all levels.... low to top end... sure will feel yr car lighter during excelaration...
better go to WEI YIP to install lar bro... cheap n more experince in this.... because need to cut out a small metal braket piece to install it....

party...so means u use 8" flywheel n mod 8.5" clutch plate to fit izit...
nice feel ar...tarik shift the clutch how?feel less slip o not?
and how much total spend for the clutch thing?

zenden 1 i feel the powerband is better at mid range rpm

carsial...not worth to mod 4g91 until 150hp...even tho on engine
if u mod until like 1 stock 4g93 wit 140hp also enuf edi....
