OK guys... I for sure need new rings. I'd like to get some prices on some other stuff, so where can I look to find these?

Check with Peaco Industries.

Why not just order OEM rings from 1stsubaruparts.com? Unless you're doing crazy mods, they should be more than adequate, and I would be surprised if anybody makes better ones for the EA82. Actually, you might call up some EA81 aviation guys and see what they've got that might cross over.

 

As far as pistons go, check out subspeed.com and go to the project RX section. The guy talks about getting custom pistons made for his RX and gives the name of the place. Ram Engines sells forged pistons for n/a EA81 engines if you want to go the hi-compression route. I would also look into getting them coated (ceramic on top and oil-attractant on the skirts).

 

For rods, I'd find a set of low mileage stock ones and have them shot-peened. Like the rings, I think the only real possibility for aftermarket stuff would be EA81 aviaton stuff that might cross over.

I'll probally just go with OEM rings for now, cause thats all that appears to be wrong.

 

I heard of these rings that are called true seal, or something like that. Basically they are half the thickness of normal rings, and you put them in so the break in the rings are opposite eachother. ITs supposed to give a better seal.

 

Might look into those...

 

WHat do you guys think of Cyrogenic treatment?

WHat do you guys think of Cyrogenic treatment?

 

Cryogenic treatment is almost always a good thing. However, if the hardening job on a part is already very high quality, cryo treatment will make less of a difference. Piston rings are probably one of the most precisely hardened parts of the engine (correct balance between hardness and shock resistance is very important), so it might not be worth it in the end.

I tried to get a quote from JE pistons a while back. talked to two different people and had verry different experiences. first guy was real friendly and helpfull had a reasonable quote for me. second guy(who really does the work I guess) had a bit of an attitude and quoted me a significantly higher price.

I decided to go stock. if you can afford it it can be made.

if you can afford it it can be made.

truest thing evAr said

talk to TWE.

gapless rings are the best if you can afford them. especially on these smaller engines where you need all the hp you can get. thats what my engine builder told me when i asked about putting them in my jeep.

 

I think that JE pistons are very cost effective if you go custom.

What is shot-peened or what does it involve? Just curious.

Here's an explaination I found. I didn't know how it worked either.
