need help for engine mods in a 4g13p proton saga engine

[DrB3rt]

hi all bosses,

i have a 4g13p proton saga engine with 12 valves. All my engine bearings is spoilt. i Would like to change my bearing to racing bearings. I heard that King's bearings are good. Can i use this bearings in my engine. why i am asking to change to racing bearing is because later i want to upgrade to racing cams and pulley. Pls if anyone can help me in the engine bearing cams and modifications and anywhere i can buy this engine parts from.

thanks you

 

[tofu_manic]

if ure aiming to build an all-out high rpm engine, then upgrading the bearings would be worth it

what cams/specs are u planning to use?

 

[lonelylilpig]

As i heard from my friend, guys from matt speed do a great job on regrind your existing cam n give u the type of profile u wanted . Other than put in racing bearings , u can go for crank n conrod balancing. It will gives u more smoothness n can get xtra few hundred rpm.

 

[tofu_manic]

yea matspeed cams give a nice fatter mid to top as compared to the pipercams ive owned previously

biggest bang for buck mod is to swap out the block to a 4g15 one

 

[lonelylilpig]

Wow this is too sweet to taste it

 

[tofu_manic]

? hehe dont understand wat sweet sweet

 

[lonelylilpig]

4G13 to 4G15 more torque mah, so in another case it is very good lor. Sweet taste means ppl happy, then more power isit more happy ....... lol !!

 

[DrB3rt]

wah wah all sifu's thanks..
actually i'm also wondering wat specs i can use for my car.
any recommendation wat i can do..
boss change blok too much work i think..he he..some more cost pocket koyak..
he he..
wanted to see if engine can take high revs..n wanting to know wat i can change lo..
cam pulleys, cams..now tat i know, i can take the conrod and crank to balance..
got any number i can call for the matt speed ppl..?
who do i go soo in matt speed thanks ya.. so much..

pls if there's anything else i can do to my engine pls advise..
thanks

 

[tofu_manic]

mod info all here :http://www.zerotohundred.com/newfor...227846-proton-4g13-4g15-satria-wira-saga.html

if i were u, id skip the engine bearings, just get cams, and up the block, either one can come first

rotating assembly balancing can wait till later on

 

[lonelylilpig]

Aiyo , i felt guilty to poison ppl pulak...... CNY is close still advise ppl this n that !! Oooops.

btw, u running on EFI or Carb ?

 

[DrB3rt]

ok thank you so much sifu tofu..
will follow ur advise..he he
any idea where i can get the cams..?

sifu lonely--don worry, every advise is gold to me..
after cny got angpau den can consider 4g15 he he..
thanks ya..

boss im running carburator le..

 

[lonelylilpig]

Like this, its abit hard wo unless u're running EFI ......
I heard some dude with 4G13 can outrun other bigger CC car with a webber . But this option is too risky ....
I suggest u stick with cams, flywheel , PNP, adj cam pulley, fine tuned extractor , or if possible rebuild the engine.
I heard nowdays 4G15 doesn't come cheap. Its quite expensive ....

 

[DrB3rt]

thanks ya boss..where i can get all the parts ha..?? eg, like type of cams..?? any shop will have ar..
kaki motor ka..he he worries kena kaki potong la..lol..quite ex there i think..

any suggestions..??

 

[lonelylilpig]

I just ask my friend about Matt speed cam, he said ard 1 k plus trade in old cam. But quality satisfaction lar..... The contact i trying to get for u.

 

[DrB3rt]

ok thanks..so i just put back the original bearings first, den replace the cams ha..
which is d most imp thing to do first..??
or do everything together..u recommend which..?
cams pnp and flywheel, or straight rebuild part by part..?
sorry ar so many quest, still new wor..:]

 

[SkYwAlKeR]

no replacement for displacement
go for 4g15 block

If i'm at ur position lar, i will go for PNP, Extractor , replace bigger carburetor, adjustable cam pulley, performance plugs & plug cable,then if got extra budget i'll go for engine rebuild, rebore, replace piston, bearings ........

 

[series5401]

currently playing 4g13p wif carb..
still planning on modding for the next stage..
we should share experience..
eheheheee..

what is 4g15p & 4g13p? i'm very new to car...would like learn some....

 

[series5401]

what is 4g15p & 4g13p? i'm very new to car...would like learn some....

4g13p and 4g15p is proton engine which is for 1.3 and 1.5 cc..
sorry, im still noob too..
a simple answer that may can help u..

 

[bobrio]

my suggestion is port'n'polish the head,change the cam(if got $$$),cluth,flywheel change to super touring,gearbox change to 1.5 wira(if cannot just change the fifth gear to wira 1.5),and the best is find for weber 1.3 carburator(quit had n $$$)....you can tapau 1.6 easly and can neck to neck with 1.8...:proud:

---------- Post added at 09:54 AM ---------- 6 hour anti-bump limit - Previous post was at 09:47 AM ----------

and dont forget to change the exhaust system to 4-2-1 and open pod air filter...

4g13p=1300cc
4g15p=1500cc
4g91 =1500cc(injection/carburator)
4g92 =1600cc
4g93 =1800cc
*mitsubishi
4g93p =1800cc(putra/gti/wira)
*p=proton

4g15 + jasma highcam (extra 10horse) + weber dcnf (another 10horse) = chase toyota altis

cost:
-4g15 blok (if u can find from ppl convert to gsr) = RM500-600
-Jasma highcam = RM5XX ??
-Weber dcnf (enough d coz u need to drive daily) = RM650 to RM800

- 4g13 gbox for super low torque pull, feels great for 0-160kmh (I tried 160kmh all the way for 150km distance, it overheats)

- 4g15 gbox for smoother, petrol saving and better top speed 180kmh (This one no overheating)

Totally calculated your 4g15 by now should be putting out 90hp++
(stock 4g15 injection from wira tricked out 81whp with some "enhancement")

You should be look at 8-9seconds for 0-100kmh. but the money u spent, can find a 4g91 which is powerful and petrol saving. I hv seen 4g91 rojak mivec head making 100whp, not bad for a 1500dohc. but tricking out your 4g15 also just fine, the feeling of using 4g15 to kick altis' ass feels good.

 

[shadow2027]

i got 4g13p...if i mod on jasma highcam? suitable? Does 4-2-1 extractor increase acceleration fuel-saving?? :trytofly:

bro,
i thought 1.3 n 1.5 punya gearbox is the same?
wat i mean is the ratio?
if im not mistaken.

nope...1.3 5th gear is lembap then the 1.5...try drive both...you can feel the diff

 

[series5401]

just the 5 gear is it?
wat bout others?
no wonder 1.5 is easy to peng meter than 1.3..
ahaha..

tq

 

[Newbienissan]

as far as my noob knowledge, 4g13 and 4g15 gbox are different. the ratio is different. coz to coupe with different power.

i think lembap is coz due to the horse power different

 

[shadow2027]

1.3 suitable for jasma hicam?

nid any extra costs if mod it into my 1.3 iswara?

i'm newbie...so i nid every sifus opinion...

wat about 4g13p with 1.5 (iswara/wira) gearbox and 1.6 wira gearbox. any effect?

 

[Newbienissan]

different displacement engine will have different gear ratio n final drive.

however, ppl do use bigger cc engine but retained their lower ratio gearbox, so it pulls much better and torquier.

factory made gbox ratio to match the engine displacement, their goal is to output optimum power n fuel saving, not performance or acceleration.

example, if using 4g13 gbox with 1500cc engine, 1st and 2nd gear can wheel spin like nobody biz, and playing between 100-170 is fun, but maximum is about 170kmh.

if using 4g15 gbox with 1500cc engine, 1st gear wheel spin only, 100-170 is not as fun as 4g13, but better top speed 180kmh++

but some claimed the new robocop design saga with 4g13 engine n its gearbox can hit 180kmh, maybe their gbox also different again. have to check the gearbox code.

anyway, 4g13 and 4g15 gbox codes are different

wats your suggestion,
if i want to still used my 4g13p engine..
do i need to change my gbox to 1.5 cc or 1.6 cc ones..
or just maintained it..

currently im using iswara lmss..
wif simple mode..

 

[Newbienissan]

just find a 4g15 blok n plonk into it. when u have more $$$ get weber dcnf. that's enough for 4g15....otherwise u will be spending too much n regret coz u can have better engine swap for all the $$

just used 4g15 block? iv done my p2p n oversized to my 4g13.. eheheee..
dcnf? currently using it.. but still trying to tune it.. webber is oke, just that its choke doesnt work, so morning have a difficulty to start up my engine..

 

[Newbienissan]

then just get the weber dcnf, good enough :)

using weber, b4 u start the engine in the morning, pump ur accelerator a few times. then let the engine revs 1500rpm for 30 seconds. kautim. for the aircond solution, maybe ficd will solve the problem on aircond idling

thanx 4 d trick.. eheheee..
btw, currently im using a 16 inch rim, taiwan.. my foreman said that it is heavy..
do u have any suggested rims fitted to my car.. as i know, the bigger the rims, the larger the diameter.. then long can play good enough.. if let say i change to 14, my long will reduce is it?/

 

[Newbienissan]

14" inch will be perfect. 15" still ok if u use 50series sport tyres but its not going to be comfortable.

i will recommend 14", coz saga so light doesnt need 15"

welcum :)

what's the the price of 4g15p engine? i mean..how to get it?

 

[series5401]

what's the the price of 4g15p engine? i mean..how to get it?

4g15p, depends on location i think.. alang2, get 4g91.. 1.5 cc too.. i heard this type is powerfull..

 

[shadow2027]

what about sabah? 4g91? easy to find?

 

[apai_Ngage]

Nowadays, 4g91 twin cam mitsubishi is around 5k if i am not mistaken

 

[series5401]

Nowadays, 4g91 twin cam mitsubishi is around 5k if i am not mistaken

4g91 5k? with or without installation?

 

[shadow2027]

what brand hi-cam is better? The adj cam-pulley, use with hi-cam?

 

[tofu_manic]

14" inch will be perfect. 15" still ok if u use 50series sport tyres but its not going to be comfortable.

i will recommend 14", coz saga so light doesnt need 15"

Hi there! care to clarify why the lighter a car is the smaller rims it requires?

4g15p, depends on location i think.. alang2, get 4g91.. 1.5 cc too.. i heard this type is powerfull..

Known several forummers who upgraded from a 4g15 to a 4g91, but the power difference vs. cost made it not worth it

what brand hi-cam is better? The adj cam-pulley, use with hi-cam?

used pipercam and matspeed, although more expensive, the matspeed 272 degree cam gave a much fatter powerband, u get a stronger kick in the midrange

pipercam is cheaper, but power gain is not as much, and is more linear, so u dont feel it as much

yeah use adj. pulley with these cams

For more info, do checkout the 4g13/15 modification thread, most of these questions have been answered there

Cheers!

wat bout jasma?

 

[tofu_manic]

a reputable forummer did a dyno test, there were real gains of about 5-6whp if im not mistaken, and this is a direct drop-in, he hasn't even fine-tuned the cam settings with an adjustable cam pulley, or adjusted the carburettor / ignition timing

oraite.. tq bro.. thnk wana install it later.. yeahh..

 

[shadow2027]

so between jasma, pipercam, n matspeed...jasma better is it? :embarassed:

if know can put up the prices including installation? ^_^
