As it is difficult to find EA turbo version in my country I would like to ask how about using EA82 N/A block ?? As I think - heads are different from Turbo and non-turbo appl. but how about short-block ???
It blocks are the same I could use new shot block form N/A engine and my Turbo heads ?
Does it makes sense ??

There's atleast one person on this board that has the carbed short-block in his Turboed car, his name here is WJM. So it is doable, but there are somethings to be mindfull of.
I looked for the write-up he had on it, but I couldn't find it, sorry. Maybe he'll see this and chime in on it.

Simply, All I did was swap the turbo shortbock out for a non turo shortblock. Be mindful of the engine temps, run a 180 deg t-stat, and be mindful of the fuel you use, and you will have to retard the timing in order to prevent the engine from detonation when you run regular pump gas. I always run the highest octane fuel from Shell, its been the best fuel. You will ahve to block off the rear pcv vent tubing, as the carbed and SPFI blocks dont have this vent.

How can i recognize N/a and turbo block?? At turbo block: should I find there "EA82T" or just "EA82" written?

To answer you latest question:
Sorry both types of block will have
EA82 - only
The easiest way to tell a turbo short block is to check for the fitting WJM tells you he did not use.
This fitting, a small pipe, is located on the back of the block almost dead center, it connects to the plastic "tree" of large rubber hoses behind the intake plenum (Aluminum piece over the throttle body with "Subaru Turbo" cast into it.)
I can post a picture if you have troulbe locating this fitting.
Also be aware the bearing in a NA engine are thinner than a turbo - the increased compression ratio will put these to the test if you do not follow Will's advise on preventing detonation.
Hope this helps
