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.

I thought it was 4G93 since the head is similar to it. Wait for more sifu to reply here. :biggrin:
It is indeed 4G engine with Mivec head actually but the setup:hmmmm::hmmmm::hmmmm:

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?

Having your oil constantly getting heated by an extractor directly under the oilpan and removing that problem in a race isn't exactly 'slight improvements' la haha.

Heat is always the hardest thing to manage. Why would he need to modify the engine mounts? He didn't shift the engine at all, just made it flow backwards.

So, that is the reason why people wrap their extractors. To reduce heat soak on the engine bay. But like you said, in a race. If this is for daily use, I don't think it is worth the effort to go such lengths unless the owner have loads of money.

You're right with the mounting question. He only played with the cylinder head, not the block. Mountings are connected to the block and gearbox right?

Yeah that's also the reason why thermal coatings to disperse or trap heat, wraps, reflective tape, heatshields, and venting all exist...

If you drive hard often and you have the money, it actually does make sense haha. Anyways he can afford a Mivec 93, whoever owns the car is decently well to do I assume.

Yes mounts are only connected to the block and GB.

But he did change the block too. If you look at the top radiator hose, it is going to the back of the engine at the firewall

If he is using CK block, then the gearbox position should be on the driver side instead of passenger side. :confused:

Maybe all the auxiliary parts for the engine are taken out? Like this is a track car... No power steering, no air cond, battery relocated to other place? Hence less wiring?

So, it is a CA gearbox and block but CK head with CA valve cover? I'm surprised the CA valve cover can fit in nicely.

CK block? But CK block's flywheel area is on the opposite side of CA block. Unless this person really reversely mounted the CK engine to achieve this setup?
as i said....just rotate the block 180 degree from its ori position and use back CA gearbox....
