Default JDM STi Swap ?'s

Hey guys I have a 99 LGT and I'm in the process of ordering a full swap and I just had a few questions on which STI version would be the best. I can't afford to do a version 6+ so with the earlier versions which one is the best, as is block internals and heads etc. I heard that the version 5 has forged pistons. Is this true? Also what usdm parts will bolt to these engines? Looking at installing a clutch upgrade, exhaust manifold/turbo and fuel rails with larger injectors so would the 02-07 Wrx parts bolt rigjt on? Also what are you guys with these engines using for tuning? I really want to run e85 because I do in ky Supra and I love it. I would like to go full standalone but I'm not sure there's a PnP like on my Supra.
Any info or links about what I'm looking for is greatly appreciated.
