mic1616, if RM is not a major concern to you......theres alot of things u can do to ur 4g18 ler. but then ah....the amount of money spent to get tat much horses....its just not worth it ler....whether the engine is realiable or not also another story. but anyways, 180-200 ponnies on 4G18 sounds abit impossible.

1. High Cams + valve springs
2. Port and Polish
3. Blue print the engine (balance + lighten)
4. rebore the block and fit in larger pistons. (displacement increase)
5. fit in a twin-cam head. (from 4G15)
6. a good complete engine management system.

dun forget..bore n replace with higher comp piston.
adj cam pulley (ada ke?)
insert 4 throttle?

mengz,

Correction for :- 5. fit in a twin-cam head. (from 4G15)

4G15 are single cam, if u are point 4G91 yes it is twincam but it does not suit for 4G18.
Should go for 4G92 or 93. Some 1.6 SOCH had done changing the head to 4G92.

Search some info form technical forum.

Good luck dude.

latest version of 4G15 is a doch engine from japan year 98 and above...its from newer lancer....the timing belt is on the left side like waja....can mod to waja i think...4G91 cannot fit la....

Dude, go to Powerzone and ask 'em what products are there for 4G18. I know they got extractor for Waja. For other items I'm not sure.

Basically 180bhp-200bhp (in N/A) from 1.6 litre engine will make it horrible (unacceptable for normal driving) below 2500RPM, if u can accept this fact than good luck.

may i know how to go to powerzone? i from singapore.

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.

Hi gurus, if i plan to do a quad throttle and bore my block and change high comp pistons(if any), camshaft(if any), port n polish, are there any thing else i can do? and what is the increase in power i am looking at with these mods? Thanks everyone for all the advices you have given. I was away in job assignment and i am ready to do my car. Any workshop to recommend btw?

 

[E3newbie]

What is you loc?

 

[Dino@Casper]

No point spending so much money on a 4G18 to get 200bhp, by than i think your car reliability would be an issue if your mechanic haven't done a good job.. better drop in a 4G93T or the Mivec.. more money Evo..

 

[mic1616]

i don't think i am looking at 200 horses anymore. but wat is the best mods i can do with this engine? and what's the max i can squeeze out of this engine?

 

[georgett]

some where to 180hp ....

 

[mic1616]

any workshop to recommend? how much are these added up? are the parts easy to find? Thanks for all advices
