4g91????

[LancerTerabo]

hurmmm... i olso dunno with this engine... and im just converting my engine to 4g91 carb (W.I.P)

and yes the carb called "electro-carburetor" or Electronic Carburetor. it has a couple wire connected to some electronic controller to get fine tune. To many wire and host around carb, distributor, and engine. It also got CO² Sensor.

im using Mitsu Lancer A172 with 4G12 1.4cc Carb SOHC. Engine similar to 4G13p or 4G15p. Gearbox i still can use my old gearbox but need to change my flywheel from 6" to 8" and i using 1.6 clutch plate (exedy malaysia).

carburetor 'tapak' same with all mitsu engine (4g12, 4g13, 4g15). I just use my stock carb. But to get more peformance, try to get megavalve carb. Becouse stock carb cannot suply enough fuel mixture in high speed.

for my car, i need to custom my extracktor becouse my car is 'tarik belakang' (FR). and i need to move a little bit my gearbox kedepan. but i think if u'r using Proton Iswara shuld be ok. No need to modify. but my mech say, proton iswara need to move top mounting a little bit.

Betul me if im wrong. My car still not done yet. haiyaaa... tak sabar to test my 'toyol' power. heheheh...

haha,sorry guys my car is satria 1.3,tats means 4G91 carb is electro carb lah,so better then the stock proton carb? co2 sensor means can put oil press or oil temp meter? or can put any meter la? the truth of the 4G91 carb is HP how much?

 

[rayracer]

> Yeah... u can use your old carb. To get more peformance, try to modify your vacum host on your carb.

co2 sensor means can put oil press or oil temp meter? or can put any meter la?
> im not very sure... but i think we can connect eksos temp or engine fuel mixture (to measure lean or rich mix)

the truth of the 4G91 carb is HP how much?
> On paper... 4g91 Carb produce about 97hp and 4g91 Inj produce about 124hp... on flywheel i guest...

the full installation of this kind engine is how much? or im just put engine?
> ha hah ha... so far im spend about 1.5k and i think it still cheap. To many think need to adjust, modify or replace for my car. Engine about RM 1k and workmanship about RM 500. Oops... registration not included. I oso dunno how much it cost. Anywan here? hehehe... im alway be a hantu driver (unregisted)

 

[alvin24]

4G91 EFi has 115hp on flywheel...

Transplant cost is less than 5k... depending on how cheap u can get the halfcut for... i think some people managed to go under 4k also.
