Gasket set for Franken build

Recommended Posts

I am putting together a frank for my Westy. I already have a '92 EJ22 in there now, but want more power/torque. I currently have a 97 EJ25D that I have put new rings in and I have a set of '93 EJ22 heads going to the shop for a valve grind and new stem seals. So rather than buying individual seals for my build from the dealer, I was going to buy a complete gasket set for the EJ22. I found a complete Gasket set from Evergreen tht is about $65 and includes all the seals. It even looks like the cam and crank seals are brown.

Q. 1 - Anyone have experience with the Evergreen Kit? is it okay, leaked immediately, etc.

Q. 2 - Is the rear main seal the same on the EJ25 and EJ22

Q. 3 - Head gasket thickness - I am going to use the cometic hybrid head gasket and I believe I can order any thickness I need. What is the thickness of the stock '97 EJ25 HG? I want to keep compression reasonable to run nothing more than 91 octane. I need a head gasket atleast as thick as the stock size.

 

Thanks.

I use Subaru OEM gaskets and seals. I suggest you do the same, except for maybe the headgaskets; for me, it's not worth the cost savings only to have to tear it down again. The special Cometic headgaskets don't need drilling, but I can't vouch for their longevity.

 

The rear main seal is the same. If you already have a "brown" Viton seal that's not leaking it might be best to leave it, as installing it correctly is difficult.

 

I measured the thickness of the EJ25D gasket 11044AA610 at 1.5mm uncompressed. I'd guess compressed it will be 1.4mm or so.

Thank you very much Ryan.

 

When I did my last ej22 re-seal, I used all OEM brown gaskets that I got from the dealer, The crank seals are doing great, but the cam seals and o-rings are leaking.

 

I will do more research.

I can. I have the recommended .040 HG from cometic, 17k miles since my build and I flog the piss out of my car. No seepage to be seen. For all of my other gaskets (Except rear main) I used the Evergreen kit from Mizumo Auto on eBay. I used a Subaru rear main and steel oil separator plate from the dealership.

I thought you needed the .051 thick gasket which from what I summized from searching was the stock ej25D thickness?

Only for the 96 which had flat tops and cleared the deck. The 97+ had dished pistons.

NO! All of the 25D's require the thicker gasket. Dished or not the piston crests above the block. The Outer 1/4" of the piston is still THE SAME HEIGHT as the '96 flat top pistons.
