how to improve the performance of 4G13 stock engine

[alcyon]

When is the last time u buy the Toyota red coolant?
Even junior like me experience the price increase.

My brother in law used to own a 1.3 Wira aeroback manual...To me, its underpowered even for daily driving. Not worth the money to mod.

Poor man cannot afford to be choosy. Underpowered also nevermind, as long can drive.

 

[gunnerzz]

sent the islala for rust management... hmmm... rm600 for it. as good as spray whole outer layer. just want to stop the rust from expand its territory.

found a rear disc, but dem... it need R15... suck up with my R13 and move out. cant unleash the full potential of double layer servo. i guess live with it.

still cannot find the real culprit of the exhaust into cabin. but while doing rust management, asked them to tampal the aircon hole/vent/pipe from engine bay into aircon vent.

let's see how it goes.

still cannot find a real/good aircon shop... dem...

Just seal the vent for outside air.
i did that for my sis kenari and my blm.
1 at the wiper cover and the other one at the firewall. The one at the firewall act as a drain when water enters from the opening at the wiper cover.

If u r in Melaka then can go to Wong at Semabok. Both my cars amd all my family cars are sent there.honest and good workmanship.

Eh....1.3 vs 1.5 has minimal price difference. 1.5 a whole different world.

Well some people 1.5 oso complain no power....

 

[gunnerzz]

These people got itch problem. Last time when buy the car new, they can get a 2nd hand more powerful car but must jaga std so buy new car which is more expensive but slower. All these people must kasi rotan few times.

.Just now i poison one of my worker to buy a CLS and he straightaway scared...he is buying a 2nd hand 2008 civic for the same price of a 2nd CLS or an E Class. I will go for the E class any day. Maintenance wise is for sure lesser headache than my waja (could be up for sale end of the year).

Don't over power the rear brakes to be better than the front......lol

 

[RENESIS VIII]

Then just use until next change.....lol

Yeah. Next time will take notice of it.

Which part of your car is affected by rust?

Today, I drove my Saga Iswara on highway for a short while. Got tailgated closely by a new facelifted Corolla Altis. As expected, my car can't pull away even when I go until over 150kmh and yet the Altis is still close behind my car. Even as I changed to left lane to overtake slower cars on right lane, the Altis still follows me.

He is using your slipstream, so its very hard for you to pull away. Also it seems he is trying to bully you coz you drive iswara.

Dude... you did not just compare a 1.8 Toyota VVTI Altis with your 1.5 stock Iswara..... What is your purpose for sharing this?

You have to be super close to be able to use slipstream

 

[lsm1991]

Yeah. Next time will take notice of it.

bersangka baik, actually he mau tailgate to reduce fc, not to overtake!

Don't take 1.3, use 1.5 can challenge 1.8......lol

Last time got one saga follow me on highway, then I switch to 3rd and boost away, he still on my tail. Later found out it was a VR4 Saga.....lol

I think he really is trying to bully. Because I was overtaking a lorry in front of me as I entered the highway. Altis from behind tried to cut ahead first but somehow blocked by me. I tried pulling away until over 150 and he is still getting closer. After I slowed down due to uneven roads (Ipoh section of highway, what to expect, lol), he overtook me. But he din't speed ahead. Just going at around 100-110.

Already very close.

Definitely not. He probably din't like it when he want to overtake the lorry in front of me but somehow got blocked by me because I switched to left lane first.

I know I sure can't win. Just want to say that after a lot of fixing, it wasn't a problem for this 1.3 to go over 150kmh.

 

[gunnerzz]

Definitely not. He probably din't like it when he want to overtake the lorry in front of me but somehow got blocked by me because I switched to left lane first.

U dont blocked him coz u switch to left lane first.Its bcoz your car is more powerful hence u reach the 'area' first.

This theory is backed by the fact the Altis is stucked behind u.

Eh, the islala is carburetted right?
why dont u webber it?

He has the more powerful car. Fairly sure you know that. So why did you temporarily speed up to 150km/h? Did you wish to not give way to him? Or was he flashing and honking to demand that you give way, hence forcing you to go faster than you intended?

Most carb fed car have a secondary needle which will function above certain rpm.this allow more fuel to go inside the combustion chambers so more bang. Not just that, the sound is kinda macho. The FC on the other hand is hancur....

Last time when i drive the pajero i will downshift when going uphill. when i learn the carb on the engine have this function i just step on the gas more than halfway so i get extra power.Not vtec like but will get me over the hill without dropping a gear.

 

[firezy]

rust? at the roof railing, this one water leaking in when using high water pump at carwash.

as the oem doors skin has been replaced some years back as it was like bullet holes all over, now the reskinned door, the trimming edge rusted again. and the whole aquarium at the rear clean up, fix up, proper hole, and resprayed.

the hinge at the back bonnet, broken. u know it is aeroback, that 2 reverse light casing cost me rm50 each. really dunno laff or cry. hahahahah..

and some other hidden areas/egde and battery platform all rusted away and fixed up. today I drove it for 140kmh, guess what? elek exhaust smell, yeah...

last night tested the double servo, wasn't in my mind of the turn as it was dark, of course backside no cars or motorist, took a hard brake and make the 90 deg turn, lucky no turn turtle like ninja turtle. if the rear disc can sumbat into R13 I would have F it. but since I enjoy the R13 like a kereta kebal, so I live with rear drum. front, in short time I will change the ventilated, slotted/cross drilled rotor + high heat brake pad to match with that double servo.

now is interior need to be done. then is suspension.

for me, the car pick up is good. but it stall at 120-140kmh, it is good enuf for day to day town driving. bigger cc cars, on straight just kasi tepi, when come corner, go cucuk. big cars usually smaller balls, but straight line, 1.3 is bau asap... so diam diam... kekekeke... of course the 175/60/r13 has downside in cornering, but heck... just F it to cucuk 2.0cc like eh how come an islala behind me at cornering? am I slow? kekekeke... whatever it is... guys, always remember, live another day have better chances... don't bcos of a moment anger/thrill...

This is like the reverse of my situation yesterday. Saga tailgated you but for me, my Saga got tailgated.

Twin weber setup? If I go for those, I need like above RM2k to buy those carbs alone. Now is not the time yet as the Iswara is a daily use car, not a weekend car.

He din't flash or anything. I just want to put a longer distance between me and him but he still follows on. Even when I switched to left to overtake slower cars on the right, he follows me.

I din't know about the secondary needle thing. Does it get activated automatically or you need to set it up?

 

[gunnerzz]

The needle is mechanical using throttle cable. The ignition also changed and this is done using vacuum. On the pajero, when setting static timing, the vacuum hose to the distributor needs to be removed and plugged. If i recall, i will post some of the service manual which roughly explain this.
