Gsir08 Posted February 3, 2010 Share Posted February 3, 2010 (edited) So I'm just about through with the freshen up on my 99 EJ25D I got, one of the last of the NA dual cams. It's going to go back into my 97 OBW in hopes that it will be emissions complient if the EGR is working well. But this motor should turn out really nice, I went through the whole shortblock, it was about to lose its rod bearings, so I replaced all the bearings and rings and just got the short block done the other day. Everything has been gone through and checked and measured and the head gasket surface is flatter than when it left the subaru dealer. Now all thats left is setting the lash on the heads and putting all that stuff back on. Looks like it should come out even decent, and for anyone that might need a motor I built my EJ22 the same way and it came out even better. And it's going to need a good home after the 2.5 is in. I can't wait to see what this motors like, the EJ22 was great but a little on the underpowered side, that extra 30hp might be nice to have.

Gsir08 Posted February 4, 2010 Author Share Posted February 4, 2010 Thanks. I can't wait to put the heads on, they came out very nice. I'll be taking more as I put this thing together. Quote Link to comment Share on other sites More sharing options...
Battlewagon Posted February 4, 2010 Share Posted February 4, 2010 That looks down right beautiful! Is that a USDM block or a JDM? Quote Link to comment Share on other sites More sharing options...
Gsir08 Posted February 4, 2010 Author Share Posted February 4, 2010 USDM. Motor came from a local subaru yard. Quote Link to comment Share on other sites More sharing options...
svxpert Posted February 5, 2010 Share Posted February 5, 2010 nice paint job! did you have to use oversize pistons? Quote Link to comment Share on other sites More sharing options...
Gsir08 Posted February 5, 2010 Author Share Posted February 5, 2010 (edited) No oversized pistons, seems like these subaru bores hardly ever wear I don't know how many miles on this one but you can see theres no wear ridge. Pretty much time to bolt the heads on, I got the lash adjusted on them both today. They got a complete valve job, resurfaced, I pulled the old nasty studs off the exhaust manifold side and cut them flat. They were reassembled with new valve stem seals and are as good as new.

i_subie Posted February 5, 2010 Share Posted February 5, 2010 While you're still at it, you should go with a set of 10:1 compression pistons and maybe some delta cams! Quote Link to comment Share on other sites More sharing options...
AWDfreak Posted February 5, 2010 Share Posted February 5, 2010 Dam, awesome!!! Keep us updated! I want to see more of the EJ25D, since it is the same engine in my Outback! Oh, are you going to use Subaru head gaskets? Quote Link to comment Share on other sites More sharing options...
Gsir08 Posted February 5, 2010 Author Share Posted February 5, 2010 ya im going to have to... even though I find it hard to believe with the head and block so flat that fel pro's wouldnt work. And make it to well over 100,000, I think its more about maintanence than anything else and how the motors driven as to wether itll lose a headgasket. BUT I did read that subaru redisgned the gasket so it must be better... Quote Link to comment Share on other sites More sharing options...
Gsir08 Posted February 6, 2010 Author Share Posted February 6, 2010 Update: Heads and cams installed, next step, install oil pump and water pump and I can start workin on getting its timing belt back on it. And yes, the heads are painted gold. Quote Link to comment Share on other sites More sharing options...
Durania Posted February 6, 2010 Share Posted February 6, 2010 Looks great man. Makes the V8 look out of place in that shop. Quote Link to comment Share on other sites More sharing options...
Gsir08 Posted February 6, 2010 Author Share Posted February 6, 2010 Haha you should see the rest of the stuff in there though, the 2.5 feels left out with all the V8's around. Quote Link to comment Share on other sites More sharing options...

Well, maybe you could get that EJ25D to sound as mean as those V8s with unequal length headers Quote Link to comment Share on other sites More sharing options...
Gsir08 Posted February 13, 2010 Author Share Posted February 13, 2010 Holy timing belt... Little more complicated than the 2.2L but still not too bad And I'm debating installing this oil cooler? Any idea what car this came from? Did they put these on outbacks ever? Quote Link to comment Share on other sites More sharing options...
wtdash Posted February 13, 2010 Share Posted February 13, 2010 Holy timing belt...Little more complicated than the 2.2L but still not too bad And I'm debating installing this oil cooler? Any idea what car this came from? Did they put these on outbacks ever? I know for sure they put those on th '91 EJ22T SS, not sure what else. I think generally they're considered unnecessary, as they didn't put them on the '92-94 EJ22T, but I think it depends more on the application - high HP, etc. Based on that beautiful block, I probably don't have to say this, but ensure your replace those rubber/silicone hose on the oil cooler. Rumor is they're a point of failure. Td Quote Link to comment Share on other sites More sharing options...
