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

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?

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.

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

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 ....

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 ........

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::driver:

---------- 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.

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

nope...1.3 5th gear is lembap then the 1.5...try drive both...you can feel the diff:driver:
i think lembap is coz due to the horse power different

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

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?/

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!

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
