Don't waste your time with magnets and CAI doesn't help with fuel consumption. Just helps with air intake.

You want a good FC car, don't buy the 4G15. Myvi has better FC. Savvy has better FC too.

If you already have the 4G15, make sure the following :

1. Engine is in tip top shape. Change whatever that is worn out or broken.
2. Use good fully synthetic engine oil 0W30 or 0W20.
3. Use high profile tyres (60 series) and small rims (14")
4. Empty your car of any excessive weight.
5. Get a performance air filter like K&N drop in. It'll help.
6. Don't drive higher than 2.5k RPM
7. Start off slow and steady, no sudden acceleration movements
8. Make it a manual. Auto cannot fight in FC.
9. No sudden braking and accelerating

Lastly,

10. Lose weight. The lighter the car is, the less fuel is needed to move it.

I have a Myvi at home already and i just got a 4g15 CARB auto that is coming tomorrow for temporary use as i'll be based in pg for a while.
1. Engine is in tip top shape. Change whatever that is worn out or broken. SOunded ok when fired up
2. Use good fully synthetic engine oil 0W30 or 0W20.Whats the perk of using good synthetic oil?
3. Use high profile tyres (60 series) and small rims (14")
4. Empty your car of any excessive weight.
5. Get a performance air filter like K&N drop in. It'll help.Putting a k&n filter drop in will increase performance in terms of having a smoother airflow which allows for more fuel molecule to be burn right? I read somewhere that cold air will help the petrol burn better right won't it?
6. Don't drive higher than 2.5k RPM
7. Start off slow and steady, no sudden acceleration movements
8. Make it a manual. Auto cannot fight in FC.Too bad don;t have the cash for it and GF needs to drive
9. No sudden braking and accelerating

if manual carb 4g15, the feul consumption quite bad actually, even mine 4g15 auto efi with basic mods only can do 16 cents per kilometer, that inculdes 50 % long distance driving!

in car camera mounting DIY :


go : www.4g1series.cjb.net for more DIY projects :biggrin:
wah sifoo so fast u diy bracket for ur vidcam ah??... lock and loaded for peksan d... unker on peksan mode...

Hello people, will be getting 11year old 1.5 auto carburetor Wira tomorrow.The thread is 100 plus pages and i didn't manage to read all, manage only to read the full 10 pages of the 4g15p page previously.
I am planning to go an 'all out fuel saving car' and i don't wanna spend a lot cause will be driving the car for two years only as long as can save petrol for the money i put in for mods in two years is ok. Top speed doesn't matter, acceleration doesn't matter as long as can come out from a busy road that's ok.
As of my understanding from some reading CAI helps to improve fuel consumption, and magnets do too. Anyone got any pics or manula to share on how to DIY CAI on Carburetor, i wanna see where the pipe is connected to for input and output. What about the stuff needed for a DIY FOR CAI.Sorry i totally noob on this. I can't seem to find a thread on this.
How about magnets , how does it work. anyone care to share
mayb sifoo fstrader can help u... previously his 4g15 carbie achieve outstanding fuel consumption, but with expense of a little weak on performance...

one of the upgrades which can save a noticible amt of FC that ive used and experienced with quite fair cost of $ is a lighten crank pulley. Not to mention the performance increase too..

Wow.110BHP.Bloody powerful. I own an Iswara with a damn tough 4G13 engine.These days, the engine doesn't like to rev and doesn't have the punch anymore.Cut lorry also hard.Engine maintained well since bought. Service on time and so on. BTW, just serviced this Monday. Idle, engine maintains at 800-900RPM(s) with aircond on. What can I do increase the revving potential with relevant power to my sweet engine?

wow dude, congrats congrats, very good results u got, never knew those oversized intake valves wud yield noticeable results for stocknia specs

lai lai come down to land of hornbill we frenly test test with my carb stocknia :biggrin:

ur power is really cun edi, with still many things that can be done, good job dude!


bro, you using stroker kit? if not, 2.0 piping ok ar for 1.5l?
no longer 1468cc dude, but 1.6 stock nia hehe

my 2 sen, if u have a 1500cc engine with a 28x/29x degree race cam and twin carbs then 2 inches would be quite cun

I'm willing to upgrade from time to time which does not tighten my income. I have a few options after following this thread closely.

(Main)
K&N drop in air filter
Iridium Spark Plugs (Wires remain ori if possible)
PZ extractor (4-2-1 as said to improve low - mid power & torque)
Mid bullet with some regular muffler
Lightened cam pulleys

With the upgrades above, will it increase revving potential?.

Bump: BTW, my 4G13 engine is using a Carburetor System

methinks u can save some money by skipping the iridiums, stock ones are good enough for the moment

the airfilter/exhaust combo is a good start, lighten cam pulley is not really needed, unless u plan to bring the powerband higher a bit but get a bit suckier low-end

to really get a nice bump in power, i would opt for 4g15 pistons, instant displacement increase, more torque, more hp

for better mid top with no significant loss of low end, then u can get some nice street cams like PZ 26x, or matspeed 272, with a cam pulley

with this, uve got a nice combo edi

my 1.3 also 2' piping maa..ok one :biggrin:

www.4g1series.cjb.net for more info....
urs was with twin carbs/full race cam, and donno what other secret stuffs la, cannot use for comparison :P

Tofu,noted. Will skip Iridium SP & Lightened Cam Pulleys for now. If i go for the below said upgrades, how much horses will I expect from my engine?.

4g15 pistons, instant displacement increase, PZ 26x, or matspeed 272, with a cam pulley,Air filter & Exhaust system.

Besides, do I need to proceed with thermal wrap on my extractor? As some mentioned that the temperature may rise too high which melts the aircond or radiator fan components. Kena once before about last year. The whole aircond fan motor melted beyond recognition.

Thanks forehand for the assistance.

i dont think 1.5 is suitable to use 2.0 inch piping. U will loose low end and the sound will be very noisy..

tofu,
y dont u come over here to test with us?? heheh... we got more cars over here... :biggrin:

i'm having this problem too... i cannot retard too much or else have bad throttle response.... engine feels jerky at partial throttle...
i've finally found a solution, tps can retard but must be done along with the distributor..now my spark plugs all brown in color at the tip and no more crusty..throttle respons very much better, fuel consumption is so-so.. :)

tps retard - turn left or right?

btw, my ecu has been re-flash..now running 48psi (WOI) and 8k redline, now da injectors are splashing finer midst of petrol to burn efficiently, and did wide band tuning also.

i should say about 20-30% increased in performance overall and more fuel saving too.

most of you stated that open pod air filter and exchaust mod are essential to improve the car performance. Can i know how much is needed for the open pod air filter and exhaust pipe mod needed?

open pod alot of different brands and quality, should be in the range of RM300-350 without the rampipe, exhaust also the same, if you are going for a full exhaust, maybe 1000-1500?
