    just install super touring flywheel n clutch kit.i think it's enough to handle ur
    power plus it's cheaper.just remember to skim the flywheel so that it weight
    the same or slightly lighter then ur oem flywheel.

    wow... very tempting indeed... hehe. Yes... I agree that if you have a powerful car basically if you can control your right foot, and furthermore by only pressing (a little bit, cause car already powerful, no need to press hard like stock one, still no go... end up using much fuel) when need to overtake... fc will be roughly the same. It is all about your right foot :-)

    northiswara, our buddies car oledi going for the whole powerzone treatment edi liao...his will be an efi machine, eh crank pulley got adjustable one meh? his setup will include most of those mods plus balance and blueprinting as well...powerzone will prolly give him the oem wira backbox to go with their piping too...what powerzone did not do is include a killer ignition to go with his setup...this he shud look into, hence the suggestion of a multi-spark ignition...engine will be more responsive, free-revving, starts easier, an spark plugs fouling problem will be reduced...power throughout the rpm will be improved...highly recommended, thumbsup all the way...kills the cable faster though wahahaha

    multi spark ignition? got this thing kah? u mean sequencial plug ignition like honda IDSL engine?

    oh ya i forgot to include the flywheel and clutch upgrade for the 4g15. hantam a semi racing clutch also not bad. most of the time the stock clutch will slip a lot.

    dont have adjustable crank pulley merr? got larr. the bulat bulat thing that spin the timing belt. soli its adjustable cam. forgot the name liao. crank pulley is to spin the air con and water pump and power steering. use light crank pulley lor.

    multi-spark like MSD la, Crane Ignitions etc etc...4got to mention, it does not go well with platinum plugs, and it shortens the denso iridium's electrodes like no tomorrow...with this, use ori copper plugs is best and gap appropriately, around 1.2-1.3mm, depending on engine compression...n is definitely not plug n play for our engine...lotsa hassles to get this installed, goes best with blaster coil too...

    easy to remember, crank pulley at the crank, cam pulley at the cam :P

    dun 4get cooling system lah

    -twin-core radiator
    -higher pressure radiator cap
    -quicker opening thermostat
    -bubble removal tank? hehe
    -redline water wetter is good stuff
    -for the daily redline-revver, get urself an oil cooler kekekeke
    -add a vent to ur hood, improve cooling hehe

    oso can add

    -phenolic material intake manifold gasket, reduce heat transfer from engine head
    -ceramic coating piston top, intake valve to reduce intake charge temp etc.
    -custom-make a crank scraper to reduce drag by removing oil from the crank as it spins
    -RPW 4-1 street header, ceramic coated, n then wrapped again in heatwrap kekekekeke (RPW race header wont fit in our engine bay)
    -upgrade fuel pump la, all crazy mods edi, for carburetted engine, get a high-volume, low-pressure pump, for EFI, get a high-pressure low-volume pump, do not mix up the two
    -adjustable fuel regulator for the efi
    -can try experiment with slitely higher final drive gear
    -mite as well balance and blueprint the whole thing
    -driver, car and wheels all lose weight hehe
    -water/alcohol injection
    -nitrous wet shot, safer than dry shot
    -oil catch tank
    -throw away aircon and powersteering
    -wideband air-fuel ratio monitor and necessary gauges to make sure crazy engine dont kaboom

    i think dats about it wahahaha
    sky, actually going with ur setup above, 2 inch ID piping i think wud be more suitable....i found out that actually 272 or so wud be best with the stroker upgrade, dun 4get changing to a longer-throw crank wud mean u lose a bit of ur revving abilities...

    northiswara, msd got lotsa stuffs yes but only some can be used, and are being sold in this forum, too....

    seanless, not really out of topic lah, one suggestion was to use a standalone ecu le, then sure no prob edi...siemens really that lousy ka?

    drexchan sez its actually more 'powerful' than the mitsu ecu, just that it takes time to learn...this one i donno, im driving carburetted vehicle..

    LOL

    This is an awesome thread. Definitely got all the sifus in one thread talking away. I'm actually taking notes. Some of the stuff mentioned is already in my list of mods. Many others, however, are not. I like to run some of these recommendations with the Powerzone ppl and see what they have to say because the Powerzone components are already 'tuned', so it'll be interesting to know about compatibilities and what other tuning work needs to be done if I opted for extra stuff.


    Yeah, I got most of the stuff you listed and my 4G15 is indeed EFI. But a Weber....I know it's powerful but it will be hell with my FC because I tekan almost all the time..... hehehe

    hello ppl! would like to share my experience here.

    my 4g13 i fitted with super touring flywheel+clutch plate besar(tak ingat size dia la)+clutch cover perdana(gila rojak), the flywheel is lightened to be lighter than the stock flywheel(tak ingat la bape kilo 6.5kg kot). a lot of difference, esp in 3rd an 4th gear. u get this feel where the gears macam jadi panjang. 3rd gear 140kmh, 4th gear 160kmh, 5th gear boleh la 175 or sampai takde power nak push lagi. flywheel ni bila ada momentum dia syok la. down side dia gear 1 nak tuka gear 2 macam lagging skit.

    also i need advice la from all u taiko here.

    (1)now im using 4-1 ekzos in my car,but i dont have a high cam. if i change 421 issit better? honestly i think my setup now is rubbish. i dont think the ekzos is complementing the sweet spots of the rpm band. what do you think?

    (2)mane nak cari drop in utk saga12v tak? carburettor punya drop in...K&N ada ke? i used to pakai open pod tapi macam taik je. lagi best pakai stock air filter, ada top speed+heat shield ahaha

    was thinking this too...but think of it..the price you change standalone ECU equalt the price yu getting a 4g91/92 so inthe end not worth...so is better plan piece by piece.

    1st of all..i`m not seanless.....hahahaha i`m Seanlee same gang with drexchan, well i couldn`t say siemens in powerfull ECU, by it was a good ems for most clean burning fuel that can be control..so by mean alot thing we can`t over do on the mod in the car.... must have a knowlegde of " know / how the siemens works" then only plan the modding, siemens is very sensitivie ecu same like BMW having..too much sensor which single mistake your car will die off.. so back to the basic...carburator still the best..hahaha

    - 421 extractor is better for street use... if ur driving style is alwiz at mid to high rpm range, 41 will benefit u more.... but if u alwiz at low to mid rpm range, 421 is ur best choice...

    - kangyoon is selling it in zth marketplace.... brand new, k&n dropin filter element for saga 12v....

    remember..lighten too much on flywheel will lost momemtom of the flywheel..yet reduce the speed of going up...but you have 0-100km/h but 100-180km/h will be slower then stock.

    1) your car is runing 4-1 is good enuff..but if you choose to have 4-2-1 you will facing hard climbing on high rpm after 5krpm....4-2-1 increase torque and respond..
    meanwhile 4-1 desgin more smooth on high rpm climb but low rpm will have abit lagging.....

    2)there is no drop in for saga carb...unless get a heat shiled with open pod..but must have CAI as well..

    3) My personal TIps for you.....go look for MEgaValve saga piston this piston design for more high compression...will give you increase of pick up and power.
    is not easy to find..coz this car produce less on the round..in malaysia....
