Why have you done this as it will restrict the oil flow to the main bearings at high rpm unlike the straight shot.

Well I'm a little discouraged now because I talked to my tuner yesterday, and he told me that he's personally had 4 4G64 motors blow head gaskets in the last 2 years, all of which under 30 psi and built by a well known engine builder on evom. This just confuses me because I've read about other people who have never had an issue. One of my favorite things about my evo is its reliability, so I really don't want to do all of this work and have a motor that eats head gaskets every 6 months. When I call around, no one seems to have a definitive answer as to exactly what combination they've seen work reliably. I guess I need to do more homework.

Mark how long have you been selling your 2.2 kit?

The only part that makes me think it could be made to work is that none of them were using head gaskets that people claim work well, which include Power Enterprises, HKS and SCE Titan. Pretty much everyone agrees that the Cometic gaskets suck, and I don't know about Felpro. The one that worries me is the Cosworth because they have a pretty good reputation.

Can someone explain to me the oiling system as it relates the crank?
I think the bearings have holes on them, and the crank has holes, and I think the block has holes where the bearings sit? So how does this system flow exactly.. like from where to where?

Block prep and head prep are key, but I have been told that O-Rings are unneeded and this is from Marco who used to prefer the 2.4 in his racecar
Crcain, I was looking for the HKS but as of yet havent found the part number. Any leads? The other gasket I have seen that looks good is the Titan SCE full copper gasket. It now has embedded O-rings around the water passage so its looking really good.
There is a Power Enterprise gasket also as I recall. Marco suggested that the HKS was the one I wanted though.

Sounds like a DSM and not an Evo though. Something to keep in mind is that the metallurgy has changed in the DSM heads to the Evo heads, and even in the Evos the IX head is more rigid than the VIII.

Ok thanks, just let me know what you come up with. I am really concerned about getting the head to seal. I've looked everywhere for an HKS hg, but every one I find is 86mm bore. Even the HKS website only lists the 86mm so I don't know how people are using them for a 4G64. Unless they are actually a larger bore than listed. I can call HKS tomorrow.
