Not sure what engine he use, but there are engine layout in that way, meaning intake front and exhaust at firewall. 1st Gen Accord is that way and even my Chery Tiggo SUV the exhaust is on firewall side.....

The video says it is 4G93. But 4G93 intake is on firewall side while exhaust is facing front. The one on this video is the opposite. Intake facing front, exhaust on firewall. :confused:

4G93 CA engine with 4G93 CK head

CA engine (wira/satria/putra chassis) = timing belt on rightside

CK engine (lancer/ mirage chassis, engine ngam2 fit into waja/persona/gen2/neo) = timing belt on left side

so when CA + Ck head, in order to meet the correct CA timing belt side, so the CK head is reversed installed.

Not much in performance but do helps in presentation.

Nope, that is not a CK head. Initially I thought so too but after looking carefully, I found out that the head (valve cover) is from the old 4G9 series not the new 'terbalik' version.


Here, look at this area that I highlighted. There is this gap area to accommodate the plug cables in the earlier 4G9 series engine.





But it is not present in the CK series of 4G9 engines.

Probably he manage to use that cover on the K head. If you look at radiator top hose it goes to the rear at firewall side

Maybe you are right... Such a weird setup. So many things needed to be custom made. If he is using ITB for intake, then perhaps I understand why he wants the intake facing the front but he is not using ITB setup...

it used 4g92 mivec ck head mix with ca block. it is not 4g93 head.

this modification becomes trend lately.

1 of my friend's neo, using CK block with 4g93 CA head mix with ITB config. manage to churn out almost 200whp a t wheel.

All I can think of it's just for relocation of the extractor haha. No heatsoak going under the engine + the weight of the extractor is shifted more towards the middle of the car...

Looks like a lot of work to do for the sake of slight improvements. I wonder if the engine mounting needs to be customized or just plug and play?

short story of my problem.

I bought a used hyundai starex about 3 months ago.

received the car on Tuesday and on saturday went for long trip and found the temperature rising. sent the car back to dealer and they sent to workshop. they changed the head gasket which took almost 3 months ( I just received the car back today.)

today refueled the car and see thick white smoke coming out. checked the radiator water while running and can see bubbles now. so workshop said need to return back to...
