Hi all,

Im using AE101 with standard 4a-fe engine manual tranny .
previously i had an overheating problem, but did not do top overhaul just change the head gasket.

so my question is that is it necessary to do this top overhaul ?
how much would it cost for both the kits + service ?
do they service the throttle body + fuel rail + fuel injector as well ?
how long does it take to do it?

its almost 2 years and the car seems running fine except high FC .
when the overheating occurred last time, its just the temperature shoot up, but not until the point that the engine stalled or died .

need some feedback from our fellow forumers .

thank you :P

First... MAny possibilities. Why did top overhaul? Have you checked:

Radiator fan
radiator
water hoses
oil level
oil leaks
thermostat

As Salam and Hi...


If you DON'T have any serious burning engine oil, oil leaks around engine head and not a very serious overheat ...don't top overhaul, better leave it as it is...

For high FC...you need a good mechanic to check it, diagnose the wear n tear, any weak parts, wiring, sensors n stuffs...

nope .
no leak . everything works fine .
temperature is fine, no water lvl drop, i do get occasional low lvl engine oil .
but it is normal when play high RPM right ?
just the occasional high RPM

i dont see any leak on the head .
idk, im just thinking bout doing it because its almost the major service time
just thinking probably it'll help restore a bit of power, response on the engine or something

High rev shouldn't eat the engine oil if your engine is good.

I tried all w40 oil wont drop even if constant high rev.

But w30 oil will drop after around 3000km

nope, not experiencing any weird color coming out of the exhaust .
everything is just normal .
that's y i stated up there, im running fine for around 2 years .
just that now i take interest in taking real care of the car .

anyway, how much would the kit and also the service cost nowadays for top overhaul ?
and do they clean the throttle body + fuel rail + fuel injector + intake manifold as well ?

Normally top overhaul just alone only. If clean throttle body for 4afe is very easy, just spray the carb cleaner.

Fuel injector if you want to clean, better send to those ultrasonic cleaning. Those who use some chemicals into the tank mostly don't work as well.

So means its not necessary to do it eh ?
and yeah, i think the engine oil lvl drop a bit since i do sometimes go for the redline .
anyway, still the same question, how much for the top overhaul kit + the service itself

im using castrol magnatec 10w-40 semi synthetic .
i just noticed, that i had to pour in almost a liter after 3000 KM .

and when i turn off engine, sounds like some sort of water droplet into the exhaust pipe .
can hear dropping then psssstttt sound like evaporation .

The 1NZFE(T) project is completed , running stock boost from a Garett AR48 turbo (suspect it might be from a S13 CA18 or SR20 turbo) at 0.68-0.82 spike on gear change (the car is a Vios 1.5 Auto)

Quite satisfied with the result , but there is a problem , after tuning even with a super rich AFR like 10-11 & retarded ignition timing , it would knock on high load condition eg.uphill / upshot on full throttle at high rpm ...

It need a thicker headgasket I bring down the compression ratio...
