4G93 problem...

[hillies]

The acceleration is good.. can easily reach 140km/h.... after reaching 140km/h, the car is as if not going to go more than 140km/h... after a long while then can get 150km/h.... it's very sluggish after 140km/h... Any sifus out there can help with this? What is the exact problem? Exhaust Extractor is using ori, mid bullet and back muffler is CF Aerospeed... piping using 2"... Is the the piping prob? What is the correct inner diameter for this 4G93 machine? Fuel regulator also fixed dee....

 

[amad108..]

maybe the exhaust flow being backflow which restrict the engine power to produce more power... (like ur muffler 'sumbat' arr)

did u know when ur playing with piping ur air-filter also need to change which need to balance with piping flow...

 

[hillies]

Air filter change adee.. piping ar, behind wan I dun think kena sumbat.. the muffler inner diameter I think is 2.2" if I've not mistaken....

ignition timing too advance??... engine tuning and exhaust tuning can also cause the reduction of top speed...

U said u fixed a fuel regulator, wat is d reading(pressure) of ur fuel regulator?

any mods in ur engine so far? any piggybacks such as afc or emanage ? if no..i think the inlet 2inch piping is too big for ur 93 setting now...i assuming if ur using straight flow (fyi..cf aerospeed inlet is 2.2inch)..u will lose at the mid-end torque...no doubt u can feel the pickup.. :)

Minor mods only.. lightening of flywheel only... Throttle body changed.. but i dunno wad car wan, the inlet is bigger than the original one... Computer settings all still using stock, no afc and etc... Extractor using Ori wan... if use 4-2-1 will be much better than the stock wan or wad??

erm.. WHat is the correct reading pressure?

these minor wud caused u a power lacking of hardtime,at the first thing...u lightened ur flywheel yet now ur using which type of clutch and pressure plate? assumed its oem original ur using,it does not support up that high temperature when comes to the certain revving and it loosing the grips den u probably will face a clutch slipped,overskimming also can caused dis as well..but the TB u had changed, err...u haftu double check whats the TB ur using now,the inlet size can make alot of diff..normally for 93..most of the ppl will choose mivec 60mm and perdana v6 ones,and did u rebored ur int.manifold when ur TB has changed? well if its not...there's no performance improvement to just plucking in a bigger TB..the mouth size arent the same,so its a waste ..and 93 stock 4-2-1 extractor isnt perform much anymore after u changed ur TB, the airflow already been restricted from the max limit that 93 can made..try to get a mivec extractor..its much more responsive compared to the stock ones,yet it more compatible to run smoother a/f ...u probably nid a piggybacks for tuning to balanced up ur fueling,ignition and airflow to match to ur current engine setting...u cant feel any better becos ur airflow setting already been messed up since the things u had changed... correct me if im wrong ..me 2 cents :D ...im from penang too...if u dun mind we can come out yamchar and talk bout it ... cheers

u are running with manual gearbox?

 

[dreamsquall]

piping too large + over lightening crank pulley = power loss in the end

Ohh.. Where is it located? THe name of the shop? Can they tune a 4G13 too??

 

[zero2hundred]

he is not those really reputable tuner ler,but he used to stay at penang in a while last time,now d moved back to his hometown sp d...he is now owned a bodykits shop at there,and u sure wonder why da heck a tuner own a bodykit shop for...ahah...well....he is not only focus onto engine performance, as well as bodykits...and hes very experience in every single thing bout car,my previous 93p was tuned by him...i can just said the result is superb,exceed the result from what i expected..
