Got the car running again last night. Bad ring placement or seat. Not sure really. But replaced the piston and threw new rings on it. No longer smokes.

Don't really update this anymore because...Well I just don't.
But the 25D in my car is quite toast. Cylinder walls are too far gone from the blown ringland and I am blowing smoke again and getting low compression.
Decided it's time to step up to a 251 short block. Got the block for 100 with a bad rod bearing. Going to clean it up and throw ACL race bearings in and new rings. New 10mm oil pump. Sti Oil pan, pick up, and windage tray.
Hopefully this will be the last time I rebuild a motor for this car.
Oh and a recent pic I took.

That 251 is going to be tougher for sure. The 96 blocks are just not cut for that kind of treatment. Are you going to open the ports to those 22E heads a little?
Depending on cost yeah I may have the heads opened up some. Not sure how much benefit there isOriginally Posted by EJ22D

Copy cat... hahahaha JK.
Good luck.
Mine is up and running except for a phantom oil leak at the rear of the motor but not anywhere on the "back" of the motor like the RMS or oil separator plate.
The high compression with the 1000 cams sure does make the motor noisy though. Maybe that is just the exhaust though. I stripped one of the header studs out of the head when I was re-installing the headers last night so the drivers side is only being held by one stud/nut.

Good luck, man. I really like your car.
This will be the last motor this car gets. If it goes down hill again it will be a parts car.

The payoff is worth every penny. Much more power in the midrange & more power to be had all throughout the rpm. The powerband will stretch higher into the rpms as well, so a little more top end.Originally Posted by Baddog
Been forever. I put a 251 short block in. I still have idle issues. But not nearly as bad.
Been prepping for Oct7ne's turbo build/swap. And working on the girls 95 prezza.
1996 Subaru Legacy L
Don't update this at all because the MR threads have gone down hill.
However I am now runnin' a 251 with 25D heads and STI HG's. One of my more favorable builds so far.
1996 Subaru Legacy L
Really!?! Do tell. What's the compression ratio on that? I've always preferred dual cam Subaru engines to single cams.Originally Posted by Baddog

that compression ratio should 10 to 1 but I am not sure I am running the same set up but with the stock Rs head gaskets so mines around 11.1 to 1.
also, when you hit 3k with this set up if feels like vtec kicks in. i was getting good mpgs as well.

It's about 10.7:1. Stock compression is 10.1 on a 251. This is a 251 with 25D heads and a THIN STI HG.
I didn't notice any low end torque drop from my old 25D/22E cammed motor. I also did intake spacers, throttle body spacer (home made) and some other stuff to the motor. As well as an EL header.

Was looking back at this. Not much has really changed at all. Going to be doing a turbo swap into the girls 95 Impreza soon. I have been spending all my car time helping Oc7ane get the turbo build finish. Which is now complete.
The EJ251/25D is running good. Some blue smoke when I get on it. But the heads had around 220k on them without a rebuild. Currently just drive it.
1996 Subaru Legacy L
I am running the STi gaskets now on my build. I really miss the high compression but I was looking at having to change the head gaskets once a year. The compression blew out the stock RS HGs in 6 months, but I can run regular fuel now which I am happy about. I was spending 360-400 bucks a month on the old setup.

How much of a difference did the throttle body spacer and intake manifold spacers make?
