M3 CRT engine changes

Does anybody know what the changes to the engine were on the M3CRT to give it a performance bump?
Hopefully it was something easy that we can retrofit to our US spec cars.
Cheers!

Before you get flamed its the GTS engine which has a higher displacement of 4.4L amongst a few other changes.

Easy: a 10% displacement bump, meaning it's DETUNED compared to the S65, since a 10% power bump would put it at 455.4 HP .

Yes very easy send it to either rd or dinan with a 30-50k check an u can have the same motor or even .2 more displacement depending upon your choice of brand. Very easy in all honesty.

What happened to that guy??? I haven't heard a word in a while.. I doubt it ever went down, and I am assuming that is why we have heard nothing.
