hehhee bro.....definitely the 4G91 twin-cam head cannot fit onto waja block ler. its the 4G15 twin-cam head, and yes 4G15 has a single cam and a twin-cam version. u can get it from a Mitsubishi Colt. the colt even has a 4G15 twin-cam mivec turbo version. get tat head, and u have a 4G18 dohc mivec :) i saw in klang selling tat head for rm2k+.

p/s: in seremban sum workshop is offering rm1k to fix the 4g15 twin-cam head onto the waja's 4g18 block.
Bro, do you know how much gain for this mod?

what a topic here...

to get 160hp is not possible with our sohc 4G18 engine..
but it is possible when u transplant the engine to 4G92 mivec rs or mixed and matched it with 4G93t block...then it bcome 4g93 mivec or in other words,1.8 mivec..

if u wish to not to transplant the engine,some mods can be done,but it's costly..

emm,what u guys just check this forum out : Team Imperials Waja

we have various modifications of 4G18 here...we got 4G18 NA heavy modded,waja mivec 1.6 and 1.8,waja with Evo 7 inside,waja with GSR turbo,bolt on turbo waja and some body styling enthusiast...come and join us..feel free to check it out...

But the Lancer is using INVEC-III CVT gearbox, the ecu can manage?
from what i understand,modifying gearbox wont increase your hp,it supports your engine from losing hp..

4g18 ecu is good enuff man...what u need to do is just to re-map it acording to your modifications...

Hi my friends, me newbie. I drive a 4g18 Waja 2005. I am just curious if the stock 4g18 engine can be more powerful and probably a racing mod would be nice. hehe

Besides what Iszo said, hows the condition of your current engine? Can perhaps bring that up to health first also.
Currently my engine health is good. Been running for the past 14 years without any problem. I can hit 180kmh at 6500 rpm on 4th gear.
