4G91 Gang..

[aLoM]

Im having the same issue as asrulac. Everytime when i start the car in the morning, the klak,klak,klak sound from the engine comes out. After about 2-3 minutes, then it disappear. Read from a few forums saying its usually caused by the hydraulic teppet/cam lifter. ACQ, u know where to get the thing checked ka?

common sound for 4g9X series i believe...only way,take out d whole head n re adjust d valves... or,jst use better quality oil...hehehehehe
Btw, can 91 engine use 92/93 ecu????:hmmmm:

if my memory serves me right, the injector pins on the 91 ECU is different than the 93 ECU. better just grab the whole 93 ECU + wiring. easier and hassle free, anyway why use 93 ECU?

better just grab a second hand emanage blue, it cost like 800 bucks + 500 to install & tune. sumore better can do fine tuning.


the hydraulic sound all 4G9X engines suffer from that. you can use meek automotive (australia) aftermarket hydraulic lifter set. Cost is about 750-800 bucks to bring it to Malaysia. no sound after changing to that, m using it in my 4G93 now.

 

[ACQ2305]

heard from others,try using 92/93 ecu..better 'performance'???
so was wondering if any of us here has tried mis-matching ecu's around...hehehe..
E-manage,probelm is,duno who knws how 2 tune it here where i am... huhhuuhuhuh

Hi guys! im new here and this is my first post.

i just transplanted a 4g91 on my lancer singkit/dangan coming from 4g13. the speed pick up is great. but i have been watching videos in youtube about how 4g91 goes and i should say mine is not as fast as those. im hoping i would learn a lot from this discussion. oh and i have a question, what do you think is the best exhaust piping size for our 4g91?

thanks all!

 

[joe_mirage]

i would say 2" is the max ... 4-2-1 config for header.

hehehe,pick i can still keep up with 1.6(4g92,4age silvertop,Campro CPS) etc etc...but always lose top speed...huhuhuhuh...
Think i have already done basic engine 'enhancement' modification 'stage 1'... but im rolling on 17in,...maybe thats d problem..:hmmmm:
2in for ya piping wud b good..

wow. i never thought our engine is capable of that. hehe.. well as of now i still face some problems like there is a lag/delay in acceleration, engine overheating, etc. etc. so im to and fro to the mech all this time. hope i could maximize the 4G91 power soon!

hehehee,but in the end,still lose... if start from a dead stop,1-2nd gear can only stay ,..after tat slowly kena tinggal...huhuhuhu...but if rolling start,kinda like wat my 1.5 is capable of...175kmph on my speedo, but others behind me were doing 190-200kmph...
Nxt plan,lighten crank pulley,change of spark plugs, maybe 92 ECU??? duno wat else i can find... :)

 

[mediocre2]

what can lighten crank pulley do ??

 

[ACQ2305]

less weight on the engine rotation.... lighter...positive comments from frens using LCP..

how do we do LCP then? how about boring out to 1.6 maybe? do u think there will be alot of gain? what else can we do?

 

[ACQ2305]

LCP,u need 2 buy it..Lighten Crank Pulley.. wanted 2 order 1 unit,but ran out of stock..
rebore 2 a 1.6,..tempting oso,but i hav no idea how much of an increase the power will be...

 

[alvin24]

don't rebore la... not worth it... so much money spent for extra 100cc and kill your reliability =p AT least to me its not worth it la... workmanship is not cheap to rebuild engine, you're better off shoving in a 4G92P block from chopshop. Prob cheaper and u gain more power from the higher compression pistons. =p But on the other hand, the 4G91 head on a 4G92 block also not to say super reliable. The gasket will leak, just a matter how when only. =p Metal gasket of course can last longer.

Lighten crank pulley is a good way to begin. You should feel better engine response from that.

 

[calvin9683]

agree wif bro alvin....just get a 4g92 block n plonk it in....much cheaper n hassle free compared to reboring ur current block.....if the engineering work screw up...then u r screwed....
but u wont feel much by just changing the block....u may feel power drop....dat's wat i feel dat time i done it....till i get my emanage in....

 

[ACQ2305]

anybody here using products from Works Engineering?? any comments?? thinking about their LCP.
coz frens Redline adjustable campulley broke at all the bolts position while driving... so,it like a snap timing belt...

 

[alvin24]

Wah... redline got make adjustable campulleys wan meh? LOLz... I've been using arospeed ones without any problems... I can't even remember how many years have I been using them already... 5 years maybe? =p

Works engineering not rim makers meh? LoLz...

dont play ppl laa

 

[calvin9683]

i'm using works clutch currently...
feel its better than exedy 3-puck clutch dat i was using in my 4g91 last time...

 

[ACQ2305]

Works rim?? heheheheh..true oso..nowadays get confuse with brands in d market..Jasma is another...
yeahh,redline adjustable campulley... frens engine 4g18,. waja... cud not find his picture though..
