Default Building a killer EJ20/22 Turbo

I'm just after some information on building a resonably cheap, but bulletproof and resonably powered motor for my Liberty RS Turbo.
The idea that I'm looking at is to get an EJ22 short motor from the N/A Liberty's, and build that to suit the forced induction.
What I plan on doing is:
a) What brand pistons and rods should I use? I want to run maybe 1.4 bar and have it rev to at 7500 rpm or more (is this unrealistic?). I want it to be quite, not one of these noisy motors with forged pistons you hear, and for it to be able to handle a thrashing and not have me worry about blowing it up. What about Cosworth blanks for pistons and Argo rods?
b) Should I have the block "close decked"? Is this really necesary for around 400 hp?
c) 2.5 litre Stainless Steel head gasket the way to go?
d) What about the crank - should I shotpeen it?
e) What about the rod bolts and bolts that hold the engine together? Bigger the better?
f) What heads should I use - 97/98 WRX heads the best bet?

Anything I have missed, or any advice people can give would be greatly appreciated.

Edit - more questions.
Currently using the Link, whats a good cheap upgrade for this motor? Link I dont think will be able to handle it. To start with I'd run this combination with the standard turbo, unless it blows on me prior. Autronics SMC would be my best bet for this - for around $3000 AUS thats the best I could get?

You should probably post this in Aftermarket Forced Induction to get more responses.

I would get the EJ22T closed deck motor to start with personally.

The only factory EJ22T motors out there are 22B motors. Bit hard to find.
Will post it also in the other section - cheers.

Isn't the USDM Legacy Turbo (2.2L) a closed deck EJ22T?

Nope. the 91-94 Turbo Legacy came with one in America. It is closed deck and has oil squirters for the bottom of the pistons to keep them cool. Trust me, I have one in my car.

It shouldn't be too hard to find one of these motors as a builder. I've seen a couple here in the salvage yards here in Colorado. The turbo Legacys were pretty common and popular here in Colorado (as is any Subaru).
