Head gasket standard, it should be ok depending on how you drive. The AFR is very important so the mixture should be not too rich or lean thats why im only using 240cc injector which is more than enough because i can adjust the ecu parameter.

oil squitter? sounds like sotong to me only hehehe mind to elaborate more about this sotong?

PadeGP was right about the oil squirter. on standard turbo engine, there is an oil squirter mounted to the block which help to lubricate / cool down the piston area (might require a better oil pump). this one become more useful when the engine was "bot'ed", where the piston have to run a lot more faster compare to without bot.
but since you mentioned about the usage of lower 240cc injector and also the relatively low boost, more or less, it could help in prolonged the lifespan of the internal engine parts. this explained why your stock gasket still able to handle the increased in power. job well done, steven

btw, i've seen a "bot'ed" 4g18p and also campro engine with boost up to 0.7bar. but without proper forging, pnp and some custom job, engine could not last more than 2 years without rebuild.

Ahhh... The oil pump... yeah i have mod the oil pump... When at high speed the oil sometimes exit the breather hose because of the high flow oil so i have locate a Oil catch tank and a return oil hose... everything work perfectly. Now i am boosting at 0.7 bar but not all the time i boost all the way. 0.7 Bar gives me a good 244hp. I always clean my engine and i also always check for any leaks. The AFR for forced induction vehicle is very important thats why i do have a wideband system to inspect the AFR. 240cc Injector able to give me AFR of 12.8 @ 0.7 bar and the injector duty cycle is about 90% at full load which is good enough. If your injector duty cycle is less than 50% on full load means very bad because you cant calibrate precisely eg: maybe too rich on idling and too lean on full boost issue and most of the people have idling issue if the injector too big. Big injector issue still can be solve by reflashing method however Big injector had higher tolerance of injecting the fuel....

correct me if im wrong because it is my theory and tested on my car and others BOT waja. Wajaray's car is very special because he dosent use any piggy back which is using reflashing method only. The memory of our rom is just 256kb where if we introduce Force Induction table into it then you have to sacrifice some other table such as warm-up table (so the idling is bad in the cold maybe for 15 sec only) The load of the Force Induction is higher than NA engine thats why they require lager table to accommodate the AFR settings...

bla bla bla bla.... fuhhhhh better stop here hahahaha

yngwie, 2 years onli huh?
do u know someone who add oil squiter to his standard block?
just to know how to do it...

btw.. u gsr ck on waja rite? manual or auto?

+1 .you've had done a good homework
bot without piggyback is something special indeed. btw, from the explanation, your engine isn't stock standard anymore. must be some pnp or forged job done
oil catch tank definitely comes handy for the excessive mixture of fuel and air. but since oil catch tank usually contained some fuel and oil mist, also condensed gas, aren't it supposed to be more practical to just manually drained the oil catch tank from time to time rather than using a returning oil hose? (unless this hose was used as a pass thru for the cleaner gas back into the intake).
btw, some modification assemble the oil catch tank in near the radiator for better cooling and less evaporation effect.

depending on the usage and 'boost crazy level' but 2 years is long enough to enjoy the 'whooosh' bov sound
and turbo enthusiast prolly' don't mind the frequent rebuilding; as long the power come back.

gt auto in sunway should be able to get it done.
yes. the mivec top is more of cosmetic purpose but at least it works.
currently on invecs-II tiptronic with some cog modification and atf cooler but i also keep another set of gsr manual gearbox with twin plate exedy just in case
the invecs-II gave way.

Mine is still considered stock hehehehe forged anything where got still stock like a virgin.... Yeah the oil catch tank return hose i think i will disable it and i would redesign the head cover with a proper ventilation.

Mivec is not nessesary for me coz i love lo rev hehehe

u r like celebrity bro.. any rumour bout u spread faster than usain bolt... hahahha
bro.. which garage u do BOT n tune by who?

The BOT can considered self custom edi since i change so many things.... Tuning is fine touch by Robyn RSdynotune after that i touch up bits by bits... Now it is perfect.... dun wanna 2 touch edi hehe

All of us here been 'racun' so much by Steven..

Nway good news for Campro the 'BOT' package is now ready, and available at Dori-Dori Autoworks now.

anyone know the market price for 4G93T ? thanks

depend on the package / mileage and condition(halfcut) or level of modification / mileage / package / and condition if its already in use.
but those cm5a variant should be more than 7k.

thanks yngwie

btw the part CM5A easy to find ? coz i surf few site it said it not easy to find some part due to it rareness ?

quite a number of spare parts available from halfcut shop.
if you worry too much about the spare parts, just mod your current engine

I BOT my car because i dont like to mess with the wiring.... If you are using half cut engine.... dont expect perfect wiring.....

cm5a manual rm8.6k auto 7.3k
the cheapest in mudah.my
u type ayie
