kob3bryant>> from kluang? nice.. very near.i from jb.. also intended to put the dohc head to my sohc 1.8 engine. but also worried about a lot of problem. and must extra money for get nothing more power. y use 1.8 and not 1.6? 1.8 head more horse power u get if compare to 1.6... our car horse power is depend on ur head and torque is up to ur bottom cc size.. 1.2k still ok. but the piston that foreman change for u or still using back ur sohc piston? how about the manifold? and the throttle body? some more the extractor and downpipe? many many things oh. wait ur new engine come out and let me c ur pics. thanks bro for share ur opinion..or u can consider the mivec engine kosong and put all the things into ur sohc engine?

if you all don't mind me sharing my 2 cents, i would like to comment a bit on the Sohc to Dohc conversion.

There is a reason why the manufacturer gave sohc to 1.6 engine especially 1.6 even 1.8. Even overseas, most lancers come with sohc 1.8 engine.

With the sohc head, you'll be able to have more torque on the lower rpm, thus loose some hp on the high rpm. Whereelse the dohc head will be able to provide much better power on the higher rpm, which give a little more hp, but you loose some low end torque. Lame man term is no much pickup.

So it is not so advisable to convert to dohc for the 1.6ccs. 1.8 should be no problem. The only reason why overseas still using sohc is due to the heavy lancer body. Maybe i'm wrong. If you guys with the 1.6cc enigne want a dohc head try search for Mivec head. This would give you significant amount of power increase.

Thank you for reading.

liki;
i gonna to take the 4g93 head not 4g92.no throttle body,intake manifold,extractor or downpipe will be changed.as for the piston,i need to check with the mech,not sure at the moment.

aarion;
thanks for ur info.since that is 4g92 dohc w/o mivec tach have been produced,i think it should be alright for that.anyway,thanks for ur info.and u miss one thing,dohc not only give u slower pick-up but also a better use of the fuel as u know one cam working compare to two cam.i am not saying ur point is wrong,but that's some good example juz like kenari,twin cam but 1000cc.still nice with its weight ratio.i was told that wira 1.5 lose to kenari for 0-100km/h.(told by friend).amazing right?but after that,kenari bhind u already due to its 1000cc.same case happen to l2,l2s,l5 and so on.these are all 660cc,not going to take original 1000cc kelissa/kenari in highway

kob3bryant,

Actually both has its own pros and cons. I do agree with you that the Kelisa and Kenari is a powerful machine. I think it is also due to the fact that the bodies are light and small.

We should not compare a wira 1.5 with a Kenari. It is not fair for the wira. The wira is using a 25 years old engine and with its superior siemen ECU. Wira is much heavier.

As for l2 and l2s, i think they have the same hp figures with the kenari. I'm not sure whether who is going to win. But both of them also fast due to its light weight.

day by day this topic going to be interesting...... still waiting to a resullt either convertion from soch to doch are the best way for 4g92p or it wil be a hell for 4g92p owner... hope more taiko2 can help us....

     

kob3bryant

oh yes!u tell the line that lied in our heart.by the way,soff muffin did this conversion,feedback not too bad.response is better than original sohc version

     

popcorn

can anyone / taiko2 write down all thing/part needed for this convertion. what part and its price also (roughtly). it can be a guardline for 4g92p owner. and 1 more thing suggested workshop.... if can la.....

     

kob3bryant

workshop at kluang lah!too far a way from u.
in my knowledge;rm1200 for the whole project
1.timing belt different(sohc&dohc)
2.distributor
3.spark plug
4,spark plug cable
5.head cover,beauty than original sohc
6.cam

thats all i know

dude is softmuffin not soft muffin
:-)

why have to change the spark plug.... soch and doch use diff spark plug? cannot use existing 1 ke?

     

softmuffin

to answer ur question, yes you can use back ur spark plug..

     

kob3bryant

is that so?sorry for my poor knowledge!
