calvin bro...1.6 piston sure has higher compression,
and since u have fitted in 4g92 piston n now running witout a fuel fine tuning,
ease of tat throttle,just imagine a 60mm t.body,wit lots of air going in,high compression,but wiout the help of air and also advance timing,high rev the enigne can mean disaster....

u guys can up grade to higher capasity fuel pump also,highway damn nice....half throttle all the way then onli full throttle also u can c the speedo really going down

if can afford e manage sure good,

hi yong..
may i know what type fuel pump did u used?? mine used before bosch tyre from mercedez really good responces but fuel comp too high..

uncle fred...from wat i heard,quite many ppl use mivec manifold also but the prob is tat mivec xtractor r not very suitable....of coz it will free up horsie coz less restrictive but mivec xtractor r tuned for high rpm out put,my dyno max hp is at 6.5k....mivec i suppose should be putting out its horsie at least 7k or over...
so i dont think 4g91 can do tat..better get a custom 1 or better still powerzone tuned xtractor...but xpensiv deh...

fuel pump bfore i upgrade i buy new car edi...no chance 2 mod...but any pump also can...bigger better,more resale value...but muz have fuel regulator 2 control...

2" piping means 1.8" innner diameter...or mayb ur ride using 2" inner diameter...hehehe...POWER-DEH uncle fred ride...hehehehee

bro calvin...after i slowly read back ur mod i saw mivec injector...so i think tat should balance stuff a bit...mayb now the easiest way was to chk ur plus to c if its running rich or lean...of coz hope its golden brown

 

[joe_mirage]

erm need some help here.. can i put gsr head in 4g91??? is it ok??? hope u guys can help me :)

 

[Yong_5290]

since i get to online nowadays for a while,most of the time i may drop in more shit here...sorry...ekkeeke...hopefully no offence

joe mirage...heard got ppl chg bfore n say got some improvement but i am not sure of it....as turbo n NA is diff in compression...y chg 2 a gsr head wit lower compression?

u wan better feel better just go skim ur cylinder head a bit to increase the compression...but of coz remember to imcrease fueling a bit and also use iridium spark plug in order to rev high

 

[calvin9683]

my exhaust is 1.8" inner diameter.....
guess its still ok la.....

i'm using some cap ayam fuel regulator.....
guess it does its job la....
but still never check whether the engine is running lean or rich......
hav to find some mech to check it....
my mech is not good at electronic stuff....
heehee......

bro joe mirage......
wouldnt it b better if u can do pnp for ur 4g91 head???
at the same time skim a bit lo.....
just wat i think la...
rather than spend $$$ changing to stock GSR head.....

 

[MiTec-i]
