4G91 Gang..

[ACQ2305]

guys,any advice about this engine,SGTi?? 4g93?? there's 1 for sale,rm3500...
is it recommended? in terms of FC,power..realibility...

 

[alvin24]

If its Mitsu ECU (MAF sensor) then by all means go get it... if its Siemen's ECU (MAP sensor) then don't get it... its very underpowered.

 

[calvin9683]

agree wif alvin...

but at the same time...
wat will u get wif the RM3.5k???
complete engine (head,block,alternator,compressor) + wiring n ecu + gearbox + anything else???
driveshaft/radiator???

guys i got some questions to ask.

1. im using 4g91 manual ecu code 1234. few weeks ago my car got problem, i can start my car but then after 5-10secs, mati balik. the pomen found out that my ecu terbakar. so he changed the ecu but i dont think it's the same code. but then turned out ok la, can start again. but just for few days onli. and now my car got same problem. can start but 5-10secs die again. is it the ecu? or alternator? or i dont know.. need help here.

ask bro Calvin,Sifu for the 4G9x series....

 

[calvin9683]

eh eh...
dun simply put me on table le....

 

[ACQ2305]

will check which series it came from..
rm3500,yeap,engine everything,GB... owner change to an evo2... bought haflcut..
might consider...if everything is right..
hope you dont mind me asking,how do we differenciate between both, MAP and MAF?? whats the difference?

 

[calvin9683]

Might be the dstributor unit... Mine hv the same probs last time.. My 2nd and 3rd cylinder are dead... Does it sounds like volkswagen engine? Haha.. I thought it was the ecu... Bt when recheck... Not the Ecu.. If im nt mistaken 1234 ecu is a universal ecu for 4g91 manual rite? Sifu2 correct me if im wrong...
:hmmmm:

thanks guys

what is the different with the air flow sensor cod 449,454,455?

Bump: what is the different with the air flow sensor cod 449,454,455?

air flow sensor cod 449 is for 4g93t gsr,455 is for 4g93 NA,454 is for 4g91.

better use 4g93 wring ecu~u got extra power...

 

[beztien]

Where are all the sifus gone?? Hehehe...
Btw.. Im planning to change my head+ecu+intake manifold+throttle body+extractor and injector to 4g93 NA... Do u guys think it's a safe mod?? Thx!!

 

[alvin24]

Umm... don't bother changing 4G91 head to 4G93 lar... its not 100% compatible.

IT will be able to jalan lar... but reliability gonna be an issue, because of the slightly offset water jackets positioning. If u use paper gaskets... it is like to leak after a while.

Save the cash and do something more worth while... like 4G93 cams (or high cams if u can afford), adjustable pulleys , fuel regulator and a management to fine tune the car with.

 

[beztien]

Ok.. I think i'll get the cam.. What if i change to 4g93 ECU and a/f sensor? Does it worth it?

 

[calvin9683]

a piggyback will giv u more gain....
