A good rule thumb on an SR bottom end is that anything more than an 87mm bore, you better sleeve the bitch.
Anyways, I've never heard of anybody making 550 hp on just 14 lbs of boost. Its a 4 cylinder for crying out loud. No fucking way in hell it can spool up a big ass turbo (thinking GT40 range) to hit that number without it being stupidly laggy.
As far as what uthemofo said about the SR tranny...HAHAHAHA. SR trannies are like fucking glass. I wouldnt hold my fucking breath on a stock used tranny with an unknown amount of abuse, holding a candle to what you're trying to do. Do yourself a favor and get a Z32 TT transmission, get with Mazwork to do the bellhousing and be done with it. Itll be the last transmission you'd need if your serious about hitting 550hp.
