SRT-4 2.4 turbo swap into an early A-Body?

So, reading up, the SRT4 engine and the PT Cruiser GT engines seem to be the same, correct? Also, what are the main differences between a NA and turbo 2.4?

pt/gt same as srt4. na 2.4 is an iron block some consider it more durable to handle the boost. and can be had for around $400-$600. where as an srt4 will start at $1000.00 and go up from there. kind of like gm's ls motor aluminum block to their lq4 truck block that is iron and cheap and people put the ls stuff on that
