4G91 Gang..

[MiTec-i]

well...most of us are already workin and mayb some busy with family commitments...i wil try answer ur question..there will be no prob fitting in the engine and JPJ...dashboard,i not so sure...price of halfcut varies...it is quite expensive now...las I 'HEARD' was 4kplus for manual...auto mayb cheaper...labour,prepare 1k plus,i recommend doin some replacement parts for seal and belts.JPJ do it urself....30 bucks...puspakom 60...
alwiz count hidden cost-timing belts,seal,driveshaft boots,brake pads...bla bla bla...

putting a 4g91 into iswara requires some amendments at the mounting (i'm not sure which one).... but i believe its very minimal mods.... JPJ will pass.... need bro ayell to confirm on this....

as for the dash board.... i saw someone fitted it into a saga/iswara.... so it can be done.... but fitment is not 100%..... so the answer is can be done....

also there's another issue.... if u r dropping the 4g91.... i assume u'd go for the fuel injection unit.... u need to source for a fuel tank dat can fit a fuel pump... if not then ur mech must know how to mod ur fuel tank to put in a fuel pump.....

as for cost... not very sure thou.... try to ask around la....

 

[ACQ2305]

Skytech,check the code of mine 454...

Friend transplant a 92 into his iswara,and yeap, a minor mod on one of the mounting. Should not be a problem. Everything pass..Only his problem now is,if the fuel tank is low, taking corners is a problem..Car seem to run out of fuel..hehehehe As mention by Cal above

 

[alvin24]

JPJ can pass for sure ler 4G91 in saga/iswara... there's many around already, even GSR also got.

The question is... whether you sendiri drive in will pass or not? lolz... you might need runner for this, in case JPJ thirsty need to drink some kopi.

hey guys sorry ive been missing for a few months. so ive listened to what you guys have said. ive swapped the s90 throttle body for a mivec one and it does do a good job. thx guys. ive also rebored my block to fit mirage high compression piston, make my cylinder head bigger, change flywheel to perdana flywheel then skimmed it for acceleration, changed my clutch to 1.6, crankshaft mivec, camshaft 1.6, changed adjustable cam pulley aerospeed and my car feels awesome. loads of power but i wanna ask you guys something. i also changed my rims to 17 inch for my stability on highways and changed to sdw adjustable absorbers for rm800 but the car is not stable :s i changed my streering rack and and steering rack bush and my drive shaft is okay but the car still not very stable. any ideas? and also the last thing i need to mod on car is some sort of management system. should i go for e manage or safc? my friends say safc is enough but all forum say e manage better. how? please help me. anything else i can mod on my car besides that? oh btw i did dyno and got 156 horsepower and thats without e manage. my injector also now 240cc. sifus please advise. thank you

oh and is it also true that when i rebore my block i need to put alluminium radiator or it will overheat? some forums said to do so or there will be loss of power. but i already changed my gasket to metal one and so far the car hasnt overheated and i always rev until max lol. but i dont drive more than 120 cause like i said the car doesnt feel stable. i drive 1995 satria original 1.3 carb. any ideas?

another thing also is that when i on the aircon quite abit of power loss. why ah :s sorry if im asking stupid questions. still a student and new to all this

156hp on wheel from a 4g91?impressive!!!

 

[marcusloo3003]

thx man.

 

[Shinjite]

What cams are you using in the 91?

 

[ACQ2305]

Wow,,salute bro,156hp..thats very impressive.. On wheel or engine?

 

[calvin9683]

Yea... Impressive figure on a 91... Cams still not highlift ones....
Btw... Abt ur engine management question... Of course SAFC would b sufficient... But wif almost the same amount of $$$ spent... Gettin a emanage would b better as u hav more tuning points n also u can add in other harnesses to tune other parameters... For ur current usage... I'd say get emanage basic harness + ignition harness then go dyno tune.... I believe u can expect 10-20hp gain....

As for stability issue.... Perhaps u can get a rear anti roll bar fitted.... Ur adjustable brand I got no experience wif... So can't comment much.... Also... The hard/harsh ride may make u feel unstable coz u r bumping everywhere.... Dat's just my assumption la....

 

[marcusloo3003]

hey guys. on wheel bro. i checked the stability problem d. guy said i should change my absorbers back to imp(my previous ones) but with good spring or go for tien absorbers which cost 2k plus :s no budget :s. my car got like 5 ultra racing bars haha but still no diff. i think satria/wira 1.6 cams bro. mechanic gave free cause spent alot of money lol. whats the diff between highlift cams? Oh so i should just go for emanage? thx for your help calvin. what if i put evo3 ecu? better? cause same price with e manage lol.

 

[joe_mirage]

ish dun put evo3 ecu on your 91. not suitable at all. stay with your 91 ecu and then o buy emanage and installed. tune it on dyno. btw 156whp for 91 is quiteeeeeeeeeeeeeeeeeeeeee impressive. btw which dyno shop did you go?

 

[marcusloo3003]

hahaha lol sorry for the noob questions =p. alright joe thx for the advise but now no budget. must save. if i upgrade the rev cut got diff ah? maybe i can do that first before i put e manage? i have a mechanic in sentul near the kfc there and he took it to his friends shop in shah alam. he also driving same satria as me but 4g93 engine. he did my car. hes damn good. cost 2k plus for everything. nearly 3k. but the 156 he put 15 inch tyres lol with my 17 sure drop. im gonna change to 15 again this week. 17 too heavy and FC very high :s. joe what about my radiator question. what do you think? necessary ah the alluminium one? cause my block rebore d

 

[calvin9683]

evo3 ecu on a 4g91 is totally useless la... unless urs is 4g91 turbo la....
regarding ur radiator prob... if ur water temp is stable... then just leave it.... if not just go for double layer radiator like those on evo/gsr.... then change ur termostat to those lower temp ones.... these should be sufficient.... to me... aluminium radiator is very much on bling factor.... somemore recent years there hav been so many types/brands of aluminium radiator where u dun even know whether they r really of quality......

 

[ACQ2305]

Marcus,wud really wana send my engine to ur mechanic..hehehee... On wheel,..damnnn. Mine is only 98whp..hahahahaha,but mostly still stock..
About stability,im using D2,(red colour) and 17in.. Front and rear bars only..seem to work fine for me..Was using GAB before this, cornering was better,but too harsh for daily use..Now thinking of getting anti roll bars for my rear.. Driving a wira..

even a 4g91 turbo will not benefit from E3 ECU without proper tuning. not to say it wont work, it does work rather gud compared to non turbo ECU, its just not efficient.
btw, an E3 ecu would work on a non turbo as well, but still better to spend your money on piggyback or a rechip.

 

[marcusloo3003]

thx for the advise calvin. ill just wait and see cause right now my engine doesnt show any signs of over heating. hopefully it stays that way haha. hahaha acq i can pass you his number if you want =) his name is ken and his workshop is in sentul near the kfc for disable people there lol. but bro you must remember he used 15 inch when he did my dyno if i used my 17 inch i think it would have been only about 130+? and that also after i spent like damn alot of money lol. i just changed to 15 inch again today =( no more glamorous 17 inch rims =( but pick up now damn sweet! =) can really feel the power and i changed my absorbers. the adjustable too hard for me :s i dont corner corner all so should be fine for me and im using lowered springs now. hopefully it doesnt hit when i carry people but if it does then ill have to change it back to standard haih..life...and wira also alot more stable than satria bro =( my satria stability shit lol car too light. my friends wira stock also i drove 160 like no feel. if my car i dont really feel confident cause car feels very light. but it improved alot after i did autofoam comfort package in my car. really imrpoved handling and comfort. rm780. you guys should try =D hahah dont worry im not trying to promote their stuff or whatever. just sharing my experience. thx for advise about the ecu guys. ill save up for e manage and hopefully i can see 170bhp =)

 

[ACQ2305]

Owhh,rim size does actually effect dyno readings? Hrmm...a debate with a few friends over this over and over,still never ending...hehehe..
Share pictures of your ride bro... mine's in page 732.... :)
Anyway,in what sense does a E3 ECU work better on a 91?? What about a 93T ECU? Will there be any difference? Tried a 93 from a putra ECU before and the air flow sensor,could not get my engine to start....
