Possible Additional Modification for Waja 1.6

[DavidLiew]

Dear All Sifus,

I owned a Waja 1.6 (A), if I am not wrong its 4G18. Currently done the following modifications:

1. K&N Drop-in Filter
2. 4-2-1 Extractor
3. GAB Adjustable Absorber
4. AR Racing Sports Rotor
5. Bendix Metal King Titanium Brake Pads
6. Denso Iridium Spark Plugs
7. E-Manage

I planned to further modify it to get more hourse power and responses especially first press on the accelerator e.g. rushing out from a junction. I like fast pick-up on the speed.

One of the shops recommended the following:

1. Aerospeed Cam Pully
2. Aerospeed High Cam
3. Aerospeed Fuel Regulator
4. K&N Open Pod Filter (however I understand that this is not suitable for my automatic transmission)

Hope that sifus here can give some precious advices and recommendations (including brands).

Thank you very much in advance.

Cheers!

Aerospeed or Arospeed? Better make sure orr...got big difference

 

[DavidLiew]

hehe...Sorry ya.... Don't know how to spell.... the popular one that most of the shop keeps :P

 

[langsuyrx]

change to alloy / lightened crank pulley shud do the trick.. little bit la.. :flute:

No bro, arospeed does exist. I just remember someone told me that aerospeed and arospeed is different company...But nvm ignore me man, cuz i can't find the aerospeed anyway now

Pai seh...

hi bro,

-port n polish the head.
-change your piping
-change to manual(racing clutch,lighten flywheel)
-stroker kit

and if budget allow bolt on turbo will be nice...since got emanage already...

when you buy the cam pulley and cams, you can choose to do the port n polish at the same time since the head is open. after doing alol these mods, u need a retune...so if u planning to BOT also, you should do all at the same time if possible and save money on having to retune again...if not...cam pulley+cams+pnp+tuning same time

change to manual...!

No worries bro. I am a newbie. I also don't know which one I saw. :hmmmm:

Thanks for your information. I understand that lighten crank pulley will increase hp. However, for AT, it will lose power when going uphill. Is that true?

Hi bro, thanks for the information. is PnP same as skimming? What is the proper piping for AT? Err...I still prefer AT due to the jam. What is a stroker kit? Sorry ya....I am a newbie

I love BOT but the cost is a factor and also worry that it might cause problems. One mechanic told me that my gear box might not tahan plus my gear box now slipped. I don't know how he know.

I heard from some people that modding the cam pulley and cams will makes the engine shake and not nice to drive. At the same time, some people told me that with e-manage, this won't happen after tuning. How true is that?

Any good place you can recommend to to all the above modifications?

change to manual...!

I still prefer AT for the daily jam in KL... hehehe

there are many types of ppl :
1. modified standard engine kaw2, feel the G-force a little bit and feel good bout it and stop.
2. modified standard engine kaw2 then suddenly got overtake by some modified car, then bolt on turbo
3. modified standard engine kaw2, BOT, feel more g-force, then enuff oredi
4. modified standard engine kaw2, BOT, feel more g-force, then got overtake by some other forced induction, change engine.
5. throw standard engine asap and change to forced induction engine, one time big money pumping out, and feel gud oredi. (1 time investment and skip all the money waste of type 1-4, but lack the knowledge of modification..)

so.. which one are ya? let ask your pocket heheheheh...

 

[AD_EG]

bro looking at ur reply, i think ur options are very limited. really. i also find it hard to advise.

port and polish not same as skimming bro..port and polish the head...when the head come out from factory its not perfect and smooth...which can cause restriction....so after porting the airflow is better...

since wanna maintain auto, and don wanna play turbo... you can only increase CC la bro but this also damn expensive already... i think last time got some guys who cater all kinds of performance upgrades is Powerzone. can pay them a visit and see what parts they have for you within ur budget...but honestly speaking...the $$ can cost a new engine transplant...so you see which is better for yourself

Ithink I am those modified little bit....feel the G-force and feel good. Then get bored with the current level, upgrade again to the next level.....feel the G-force and feel good. Then get bored again and ........... non-stop

Thanks bro. Where is Powerzone? You got the address? I understand n/a could be more expensive to modified in the long run. But it allow modification slowly. Since my pocket and knowledge are limited, I thinks thats my only choice although I love BOT

Bro have you dyno your car?
I think u should have done since u're using emanage already.
Mind to share how many hp or bhp u get?

Bro, I did my Dyno about 5 years back during my second tuning in my hometown. The chart shows improvement in hp. Unfortunately, I lost all the records when I moved to KL. Still trying to locate the files where I kept the records.

Initially I feel great after tuning but the longer I drive (after few years), I felt the power is not there or not enough. Don't know if it's due to psychology only or my car need an upgrade or retuning.

whoaaa.. good for you la... heheheh.. from bottom to top.. but then, to play with NA is a huge diffrent with turbo, to get HP, more $$ need to be throw out..

simple calculation:
NA : 1HP = RM1000
Turbo : 1HP = RM10

True bro. It's more expensive to play n/a. However, it's allow me to upgrade little by little while BOT need to pay all at one time. Poor people like me cannot afford Plus my auto transmission might not tahan even on 0.7 boost

Just did a power run on the Dyno this morning:

Max Power = 82.44
Max Torque = 11.72

Air Fuel on the red line.

Is this under power?

---------- Post added at 12:32 PM ---------- 6 hour anti-bump limit - Previous post was at 12:08 PM ----------

I understand that on paper, 4G18P should have the following reading:

Power (hp) = 102@6,000rpm
Torque (Nm) = 140@2,750rpm

I asked the people selling performance parts how come my reading so low. Althought I have an 17" wheel and my car is 2001, there should not be so huge different. They told me those on paper are "Fly Wheel" while the Dyno I did is "On Wheel". Does any sifus here got the "On Wheel" reading for original 4G18P?



---------- Post added at 12:36 PM ---------- 6 hour anti-bump limit - Previous post was at 12:32 PM ----------

I just found out my reading for Power is PS and the Torque is Kg-M. What's the difference compared to hp and Nm?

Hi bro, your car in bhp which is on crank might be around 100 plus bhp. which is much more than std. But i think u can gain more since u had the emanage, just grab a hi cam and adj. fuel regulator.
Just wanna share, my fren waja 4G18 Auto 17inch rim also
fullset exhaust system, apexi ori intake, adj. fuel regulator, jasma hi cam and thats all.
After dyno 117bhp. :)

 

[AD_EG]

ps 82.44 convert hp = 81whp

normally this is lower than on paper because on paper follow crank. when taht power is used on the drivetrain/gearbox they say there is a 15% powerloss for 2wheel, estimate your hp figure is 81+15% = 93hp@crank.

still quite low la bro...not sure why this has happened..maybe tuner not so good? not sure bro...i also dono why they use diff type of measurements..some use hp,some use ps etc

Thanks bro, do you know who tune it for your friend? I have put in high cam, adjustable cam pulley and adjustable fuel regulator but still that low

Thanks bro. Yes I agree. Its still too low. You got any good tuner to recommend? :rolleyes:

 

[AD_EG]

i recommend joshua @ millenium bro...in sunway

 

[DavidLiew]

i recommend joshua @ millenium bro...in sunway

Thanks bro. Yes, my friend also recommended Joshua. Will go once got the time and money :rolleyes:

By the way, is there any other think I can do to increase the hp and torque other than BOT? PnP? Covert to DOHC? Water-Methanol Injection (Not sure if its for turbo cars only)?

---------- Post added at 03:48 AM ---------- 6 hour anti-bump limit - Previous post was at 03:37 AM ----------

By the way, I have done the following 3 weeks ago:

1. PiperCam 272 High Cam
2. Arospeed Cam Pulley
3. Arospeed Fuel Regulator
4. Arospeed 3 Core Plug Cable

On top of my:

1. E-Manage
2. 4-2-1 Extractor
3. Denso Iridium Power
3. K&N Drop-in

The result on DynoJet shows:

Max Power = 82.44ps (before) & 88.95ps (after)
Max Torque = 11.72Kg-M (before) & 11.96kg-M (after)

I think its still under power.
