I am reading this and am assuming you are referring to 1st and 2nd gen ej22e heads?

and if so, does it use the composite or MLS head gaskets?

I have seen in several threads the mention of Delta Cams. I went to their website but could not find any information on pricing. Anyone have any info about cost?

Do you send them your cam and they re-grind it for you?


I wanted to get a ball park number for doing the DOHC cams.. is $250 sounding like too much?

I wanted to do the cams on my Ej22 but I changed.

It's about $80 per cam give or take. So the DOHC's would be about $320.... as I said give or take.

Use head gaskets that match the block.

You can use whatever head gaskets you want. I used MLS for obvious reasons.

I'm pretty sure I used the ones that matched the heads. With an open deck, it doesn't matter where the coolant passages are. You don't want to block off the passages in the heads, though, so you get the ones that match the head. Unless, of course, I'm missing something.

ej25 has a bigger bore, so the gaskets need to match the bore.

Oh, ok. I sort of thought I was missing something obvious when I was typing that out.

Ok, so I was out at GD's place today doin some exhaust stuff and he decided to give me a little ride in the franken brat...with the JDM STi tranny, holly crap! grip like no other and the thing has torque written all over it. Goin down I205 was nuts. Anyone questioning the power of one of these builds is a fool IMO:lol: its not like anything I have ever been in and I've been in some fast cars. I'm glad to say I was able to contribute a little to the build with the 5th gear from my old trans, little power house.

Closed course, professional driver, I'm sure:rolleyes:

You actually contributed 5th gear and the case, I thought. The STI gearset and fancy diffs actually makes it feel a lot more controlled than it did before. Your 5th gear is a little odd. I thought it would be more of a cruising/fuel economy gear, but it actually has enough power behind it. I have yet to have to downshift from 5th for a hill or anything.

I just wish more people knew how gutless a stock Brat is, that way more people would flip a lid when I go by:lol:

well, trust me, going from about 6 or so Turbo Legacies, to a CA spec BRAT, i was like, huh. hills sucks, passing is thought to not even try, etc.

no fears, still got a ej22t longblock and the crossmember sitting on the shelf with only 85k on it, but there are no mechanical problems on the old brats ea81, and it doesnt use or leak oil etc, only 129k on it.

I have replaced the stock CA spec hitachi with a Weber, and it is still gutless, but i was able to pass a ea82 going 75 and we both had 27.5 inch tall offroads on and lift.

My FI ea81 is pretty gutless...

Speaking of frankenmotors, I'm going to be making one with delta cams for my legacy.

Brats feel a lot more tank-like than more powerful Subarus. Mine also feels more connected to the road. I love that I can floor it in the Brat wherever I go and nothing bad happens. If I try that in my other car, I'll end up in a ditch/yard with at least $5k in damage.

When my Brat was stock, I took it on a 500 mile trip one weekend. Something happened halfway through, and on a major hill coming home, I kept having to downshift. I started getting worried when I downshifted to 1st, because after that, there were no more gears:confused:

Have you done the mounts yet?

I've got a ej22 from a '93 legacy in my Loyale; any problems running those components with a 2.5 block? Many folks talk about ecu management systems...

Gaskets need to match the bore AND the coolant passages in the head.

 

No stock gasket correctly does this.

 

What you need are these.

I did this swap in my outback and wasnt impressed. Tt he auto trans sucks up too much poer to feel a difference. I did not install the delta cams or do an exhaust either so that may be part of it. I just picked up a forester yesterday and I am considering dropping the franken motor I to it after replaci g the cams with delta torque grind cams. It has a5 speed and is a lighter car so I think it will be better suited to this engine. I used the 2.5 mls hg and if I don't run premium it will ping some so my compression is a bit higher than using the appropriate cometic gasket I believe.
