The navigation is a little strange, some pages aren't accessable from the top. So here is the root

And here is some of the more interesting pages

pretty freakin sweet man!!!

Has some good info on heads as well a flow testing.

Also has some excellent fab skills. That's one beautiful engine!

Wow, that's some cool stuff.

I wish I could have that engine in my legacy.

Very cool, the aviation crowd has loved using subaru engine for years. Early EA81's and EJ22's are most popular. As a pilot I can tell you, those old motors in most certified aircraft are ancient pieces af garbage. The technology in those things dates back to the 40's and 50's. So any Subaru motor is lightyears ahead them.

A friend of mine works as an engineer for a company that does aerospace carbonfiber molding and there are a lot of aviation guys there who build their own planes and such. He came over here and we were discussing how great these engines were for over an hour while other people got aggravated. Apparently all the guys he works with love the EJ22 and he was talking about how awful the Continental and Lycomings were.

The EA81's are real nice motors, too. Don't breathe well or make a lot of power, but they are indestructible and maintenace-free. The cam is gear driven, so you don't even have to change a belt.

I know its been said before but it makes me really happy when I see so many airplanes and rotorcopters relying on this engine.

It surprises me that they are reliable enough for people to trust it with their life.

We also cant forget about all the VW guys. It may just be luck but ALOT of conversions are taking place in my area. They are always competing for parts and used cars :evil:

I just wish SOA would realize this and stick to making quality products rather than trying to impress the cool crowd.

I also wish everyone would realize we wouldnt be getting all these cool cars from other manufacturers if it wasnt for the WRX being introduced in 2002. Now look at what we get, EVO and GTR to name a couple.

Wow, after re-reading these pages, i just realised the stock NA 2.2l pistons has 14.5cc dish ... the measurement we need to get a good CR with DOHC heads !! hehe

.. and the stock pistons in the EJ22T are not of an exotic material and have held up to high boost without melting, I see no reason for the NA to be any weaker.

I'll try to get a hand on a 2.2l na piston and give it, with my 2.2l turbo one, to a friend to do some resistance testing on them to see if they are as strong.

if so.. that would be my cheap solution ;)

90-98 had 9.5:1 CR,
99+ had 9.7:1 CR.

that's good..... that's REALLY good :)

the 2.2l na pistons has a cost that is not really advantageous (?) compared to forged pistons (110$CAD x4 + 250$CAD (ring set) )

I'm waiting for availability and prices for 22b pistons and ringset.. (8:1 cr with dohc heads)

Im not that big of aftermarket pistons. Before posting a ton of detail look at the "discussions" on nasioc about if the STI pistons are cast or forged.

I prefer the stability of normal pistons over the increase in strength of the others

I've written a mail to Richard Marsan, the national manager of the quality assurance dept. at subaru canada about this piston concern... eager to see what he'll reply ! :)

also, on Subaruglobal, there is a bit of infos on the "new" pistons vs the old ones.
Follow the 'piston' link from this url :
http://www.subaru-global.com/about/parts/index.html

i'm also waiting for 22b piston prices.

Ok, Richard Marsan replied something i was expecting .. In short, he don't want to answer, for legal reasons (he don't want me to sue him if my stuff break). But sais that Turbo pistons are a lot stronger that 2.2na pistons. He concludes saying "I wouldn't take risk", doing reference to using forged pistons.

I then talked to some 22b owners asking for 22b pistons... they told me not to do so since prices are too high.. They pointed out JE-Pistons had already done some copies of the 22B pistons, so it would be easy to order from them. (just call a forged 22b piston set.. hehe) ~550$USD 4 pistons + rings

that's it for my "researches" on that subjects, i'll finally go for forged pistons from JE. or anybody else..

What company is best ? JE ? Arias ? Ross ? another ? hehe

:) I`m using Arias pistons in mine; same pistons used by Tony Rigoli and Easy Street motor sports. That was good enough for me!!--Rod
