Old but useful thread.
I've been having issues with unstable idle and engine revving up to 2.5-3k rpm by itself when coming to a stop. After a week or 2 of odd behaviour I ended up with car in limp...

There is always the chance that the clearances were all out of spec from new. Maybe subaru is a bit sloppy building them. Maybe that's why they're a bit more prone to failure than other engines.

Do you have a ring compressor? Did the rings fit in the bore before you fit them to the pistons? Did you check the ring gaps?

No fatal issues. I run custom made pistons in mine with a bit looser clearance and aftermarket rings. I get a puff of smoke once every 8 or 10 starts.

Rings very slowly rotate as the engine is running. I guess they're trying to avoid having the oil ring gap end up at the lower side of the piston as oil can seep through the gap when the engine is...

Those tabs are very rarely seen on any rings. Just assemble new ones as normal.

Another tip for fine tuning clearances.
If the std bearings are to loose and the 0.025 oversize are to tight, you can use one of each shell on a journal which gives you 0.012 clearance increments....

Sleeves were made by LAsleeve. They'll likely make you another set if you ask them. Some of the forged piston manufacturers will do custom stuff. Gaskets are trickier... I got greedy and had to...

It is impossible, so I decided to improvise. Custom made 90mm 11.5:1 pistons and custom sleeves. Modified OEM head gaskets. Just under 2.2L on the stock crank.

Engine running! Oil change is about 5.5L with the sump spacer.
Pressure is good with the big pump. When cold its very high, bottoms out the 100psi gauge at about 1500rpm. I have fitted a heat...

OK, so it seems it was my mistake :bonk:
When I pulled the supercharger I left the injectors/fuel rails on it. My spare stock manifold had all of the original hardware on it. I am not sure of the...

Rod 1 is fed from 1st main bearing. Rod 4 is fed from 5th main bearing. Rods 2 and 3 are both fed from 3rd main bearing. It will always be 2 or 3 rod that fails first as they have to share oil.

sump spacer and mesh screen

10mm thick sump spacer and new mesh screen in pickup. Mesh is the same pitch as OEM, but much larger area. The spacer has tabs on it that I will probably use to add a brace to the pickup. Vibrating...
