Wat's the max boost for a stock 4g93t terbalik?

[ehdrian]

Bros, i was told the 4g93t terbalik has a 9:1 compression which is the same as the evo3..i've heard ppl say that engine with this compression is not suitable to boost more than 1bar unless it has a thicker metal head gasket to lower the compression..so i was wondering is it safe to boost 1.1-1.2bar on a stock 4g93t terbalik(with the correct afr tuning using emanage)?...thanks in advance

1.4bar max boost with correct afr tuning (safe play).. assume with standard piston rite?

 

[ehdrian]

yaya..everything stock..1.4 bar without metal head gasket to lower the compression?..

 

[chrissyong]

stock internal and head stud and injector not safe for 1.4 bar~

 

[ehdrian]

dun think the td04 is making any more power at 1.4bar, right?..bro, in ur opinion, is it safe if i boost around 1.1-1.2bar?..

don boost too much lah.hard to chase u lah

 

[lozo]

stock engine (no management, fueling, or other supporting mods), max boost is stock boost = safe

u dun even know me, hw to chase me leh?..hehe

 

[speed2horizon]

Are you talking about the GDI version of non GDI version..?

 

[ehdrian]

hw to differentiate?..

One is direct injection... one is mixture intake...

But can u do it the other way round...?

Planned for a desire WHP u want... Then U start doing research on how to achieve and what pressure u should induced...

Instead of asking how much pressure can be induced into the engine... Sounds like trial and error to me... So, if someone tells u u can only boost 1.2 bars, u're gonna boost 1.2 bar and stay with it..? If someone tells u can take 2 bar, u gonna try 2 bar and detonate ur engine..?

BTW, the internals of the engine can take more than 300HP... It all depended on the supporting mods. And TUNNING OF COURSE

+.+" PLZ Don't call me sifu... Later all the bigger SIFUZ out there laugh at me....

Well, back to the topic, if u're gonna leave the internals stock and not even reducing the CR with metal head gasket. And IF ur internals are in tip top condition, it can withstand the boost of 1.3-1.4 bars with at least 510cc injectors + Slightly bigger intercooler(VR4 Seems good) + At least a piggyback with good tunning.

But the TD04L is not capable of supplying suffiecient air to be efficient at the pressure of 1.3-1.4 bar... So, no point. Then u will need at least a TD05 14B. But 14B is damn 7 old and not easy to find good condition. And u may opt for a 16g.

bro u r 1 of the many sifus out there ma..hehe..i just plan to boost up with a piggy back to support the tuning..i'm looking for somewhr around 1.1-1.2bar cos td04 isn't making any more power after dat..gonna leave the engine totally stock for reliability..

If everything stock including injectors, better stay not more than 1bar. Insufficient fuel injection will even harm ur engine more... If u wanna gor more than 1bar, look for VR4 injectors. 450cc. And at least RON 97 or V POWER pls...

The Turbo can provide the pressure.... but not the cfm. It's good for response...

Bye bye... Chiow!!!!!!

 

[ehdrian]

thanks bro for the advise..take care and see ya..

i have a fren running same setup with yours...only thing he did was install emanage blue, walbro intank fuel pump, bigger intercooler and fuel regulator...stock engine setup...went on dyno and try to boost 1.2 bar but stock turbo unable to push that far, so boost 1 bar with 225 hp on wheel

the 4g93t piston ring is damn lame, u after remove the ring u can use your hand and finger to break it~but the toyota 4agze piston is damn hard,haha

Toyota semi forged ma... Btw, it's all abt tunning.
