mine 20 years at 160k km...
no issue with the rings and valve... touch wood.... choi... choi...

20years and only 160k km?
Thats considered just run-in.
Maybe even the cylinder honing mark is still there...hahahaha.

that's why still in the garage... local saying... "jual tak kaya, simpan tak rugi"
body still has the original sticker

 

[minibeany]

Admit it lah. You are hoping for an something to happen. Then got excuse to drop in a GSRT into it

 

[sweelt]

so big ...very big face

 

[parakey]

Learn from the CAT above . He didnt wait for engine to konk, to go on turbo route. That's one hard core dude

 

[Latebloomer]

Btw guys.. is it worth if i were to change my injector to higher cc on stock engine?

 

[vr2turbo]

Valve seats sorry. Basically incomplete combustion busting out.


Personally I'd fix it. This kinda thing usually means overhaul. Piston rings and valve seats

I thought valve seats usually smokes when idling. One of my previous car had that, but normal driving no smoke, only at idling.....

During high vacuum situations like idle, cold start and engine braking, engine oil gets suck from the cylinder head into the combustion chamber.

what do you think will happen... keep things simple. imagine just dumping more fuel in there, whats the expected result... remember just dumping fuel and nothing else into the combustion chamber

larger injectors won't shoot more fuel in la. It's just underutilizing the injectors. Not a great thing either

Large injectors and stock ecu?

ehh it will let more fuel in kan...

 

[Izso]

Let me clarify. The stock injector duty cycle is usually 80%. So say you're using 150cc stock injectors, then you're shooting about 80% in super simple terms.

If you plonk in 500cc injectors it'll be running the default duty cycle of 80% unless you tune it otherwise. So you're shooting 80% of the 500cc inejectors. But that's also assuming your fuel pump can cope with the extra load. If fuel pump is insufficient and injectors not running at it's preset duty cycle, I think something is going to fail pretty quickly.

So thats mean Ecu come first then larger injector plonk later on?

 

[Izso]

Probably fix the smoke first.....

 

[lsm1991]

no.... wait... are you planning to go stand alone?

 

[Latebloomer]

no.... wait... are you planning to go stand alone?

Always saw the word stand alone but still dont know what does tat means. Newbie here

Already on it

Modern cars have ECUs to control the injectors and all that stuff. People add on piggyback ECUs to "cheat" the stock ECU to add more fuel or increase or decrease engine timing or all those sort of things. Piggy backs are limited in what they can do and some cars don't even like piggybacks and will overwrite anything they do like the Siemens VDO ECU on the 4G1x protons. Piggy backs you'd be looking at Emanage, Unichip mostly. There are others as well but personally I don't think Piggybacks are worth the money or time.

Standalone ECUs completely replace the cars stock ECU to manage everything and as a tuner it means you can tune the car however you want it to run. More lean or richer at certain water temps, cut off aircon whenever you hit a certain RPM (to preserve your aircon compressor), and sooooo many more things. Links ECU, Haltech ECU, ECU Masters, MAXXEcu are all standalones (there are way more btw).

Eh kawan.. use google once in a while la

^ this, but just saying... standalone is overkill in your senario Latebloomer, the cost of the standalone will exceed the value of your car, or come close to it (pending on what u end up with)

Tarak hardcore lah, masuk engine only. Hahaha...

After all the previous mod, extractor lah, plug, plug cable, air filter, polish port, etc. etc., nothing feels the same for transplanted turbo engine. Still get the oomph, even after 20 years owning it.......lol

uncle @vr2turbo your force very strong ...

terbuuuuuuuuu

as we all know, raw dollar per h/p, near impossible to beat forced induction... we shall wait for the electrics to come.
