Cometic HG fit on EJ22T Block Pics

Wedge · 01-28-2004, 09:49 PM

Thought I'd post a couple shots on the fit of the Cometic HeadGasket for the EJ25. As you can see, it's not an exact fit, but it should still work. If you look closely, you can see the o-ring design of the Cometic HG.

And here's a shot of it placed on the EJ25 heads.

(Block rebuild is 'almost' done!)

are those headgaskets going to promote more boost?

todnar · 01-29-2004, 08:15 AM

Why didn't you buy the gaskets in EJ-22T form?

Wedge · 01-29-2004, 09:03 AM

STi= Yep. Thats exactly why I chose these.

todnat= Simple, more boost without having to worry about blowing a headgasket.

latinskllz · 01-29-2004, 09:10 AM

You think the coolant passages in the block is going to be a problem since the gasket covers some of them?

todnar · 01-29-2004, 09:18 AM

Ok.I just thought it was better to match bore size. What thickness did you get? The HP series is available for the EJ-22T in
.030",.036",.043" and .057".

Specs in HG : EJ25 / 100mm / .043-HD /

Wedge · 01-29-2004, 10:41 AM

OK! PROGRESS!

I just got a call from the shop this morning! The shortblock is complete! I am using a brand new EJ22T oil pump, and water pump (which I think I'm going to have to change to the EJ25 water pump, dunno if it'll align correctly with my radiator)

Also, I don't know if I "need" to replace the headbolts. I looked through all the service manual, and couldn't find anywhere where Subaru specifies to have them replaced.

Here are the pics!!!

Cool! I'm actually worried about my CR being to low on my build with the DOHC heads.
Where did you get the pistons from?I'm thinking of getting a set made so I can get my CR to be 9:1.

-Tod

Wedge · 01-29-2004, 11:09 AM

They're Ross Pistons, custom made since I had the walls bored. And I had them ordered 8.5:1 also.

todnar · 01-29-2004, 11:25 AM

Thanks. I was on their site yesterday looking around.May I ask what they charged for the pistons and rings.And what brand of rings did you go with?

-Tod

Wedge · 01-29-2004, 01:21 PM

I paid $580 for 4 custom pistons, and total seal rings to go with it. I do have a wholesale discount though, so dunno how much retail would run.

todnar · 01-29-2004, 02:19 PM

Thanks.
Good to now they will have an idea about what I'm talking about with the 2.2 when I call them.I need to get my heads back from the machinist so I can cc them again after the combustion chambers got worked on before I do though.

My Cometic gaskets in EJ-2.2T form were identical to the ones that came with the Subaru gasket kit for the 98 2.5L except for bore size. I notice you have a 2000 and the SOHC heads.It looks like the 2.2 gasket would have been pushing it with those combustion chambers.Ecspecially if you had them worked on.

I'll check the coolant holes on my block compared to the gasket when I get home tonight.I'm pretty sure part of them were blocked just like your pics show.

Later, Tod

Scoobyslack1 · 01-29-2004, 04:36 PM

Vic, you got the same #?
I'd like to call you and talk about the gaskets.
I'll be pulling my motor soon to do the head swap

Wedge · 01-29-2004, 08:20 PM

PMing you Alan.

Wedge · 01-29-2004, 08:32 PM
