:) looks like many of u are also having fun with the 4G93 eterna. I had one too, transplanted into a Proton Arena. gotta admit, it's a god damn headache. Yes, consumption sucks, mine was auto, and i could only manage 250kms on a full tank. i had also done a full overhaul, changed to mivec pistons, new throttle body, K&N.........etc etc. It's still a sucky engine, but johndilla my friend, i cannot help u with ur problem...
I think the solution is not to buy this engine. I just threw away the manual, i could probably still pick it back up. anyone want it? it's amazing u get 450! u got a 80 litre tank is it? i don't know of any 4G93 that gets 450 even in manual, my Gti manages 350 only.
im using this engine too,sadly but its been like 1 yr plus after installation but there some probs, that is yet to be solved.Power wise,on a personal level,i cant get anywhere even close to a malaysian 4g93p...be it putra,gti,le or what ever...sad(:.But surprisingly,ive never exp'ed any breakdown or wiring probs so far.
My ECU-6123(MMC)
Even with 4g92p also this engine kena tapau at traffic light. One more engine got the same problem (less power) is 4g92 dohc non mivec from japan halfcut.4g15 can beat it.
well,ive not really tested at traffic lights,but one for sure is the power is not there as its supposed to be.Dunno whether it's caused by the ECU(6123) or someother unknown reason...the piston is flat,real flat.The 4g93p-putra/gti has a little curve on top of its pistons.
u are right.The piston is real flat like gsr piston.The compression also low.I make this comparison between 4g93 e52 and 4g93p:
I get this spec from my surf for 4g93p(r3).This is the difference:
4g93p
POWERTRAIN
ENGINE 4G93P 4-cylinder 16 valve
MAXIMUM POWER
R3- Max output 105kW/140bhp @ 6100rpm
Gti- Max. output 139.9 PS (138.0 bhp) (102.9 kW)@6000 rpm
Eterna- Max output 102.97kW/140ps(138.23hp) @ 6500rpm
MAXIMUM TORQUE
R3- 168 Nm @5600rpm
GTi- 164.0 Nm (121 lbft) (16.7 kgm)@5500 rpm
MITSUBISHI- 166.71 Nm @5000 rpm
Compression ratio
GTi- 10.5:1
Eterna - 9.5:1
TRANSMISSION
5-speed manual
GTi and r3 produce higher bhp in lower rpm.The torque for r3 and gti at higher rpm. So from this spec sheet,what the conclusion? Can ppl or sifu give conclusion?I can see the compression ratio of eterna 4g93 is lower .Thats why it produce slower response than 4g93p.But for high rpm it still can give maximum output like 4g93p.If i am wrong plz correct me.

bro,
1)what do u think?will the compression be higher if only i change it to the ori putra/gti pistons?
2)Btw,I do suffer from lost black oil,very noticeable esp after running new oil change for like 3000kms...anyone else having this problem?
hehehe just did my overhaul...
eat engine oil a bit...
looks like faulty/old valve seal..
bought the top set consist of valve seal, gaskets cost me RM550.......
