Swapping K20z3 engine into 9th gen SI

I wonder why honda didn't initially put the k24 frankenstein engine in the 9th gens when they first released them?? I guess Honda was trying to save money and take a shortcut by simply transferring the tsx engine over. Even when they did a huge exterior and interior makeover for the 2013 and 2014, they didn't touch the engine. I guess it was too late at that point because they already had plans for a massive redesign in the making. Too bad honda became too complacent for the 2012 models, either wise they could have probably set history record breaking sales for the SI. 2013-14 sedan body/interior combined with k24 frankenstein equals very possibly the best SI in history.

Because of meeting emissions standards. Same reason for the collector as opposed to a traditional header.
 
***CORRECTION***

Earlier in this thread in one of my posts, I mentioned that the 9th gen si had vtec only on the exhaust cam. That is incorrect and a mistake on my part. The 9th gen si has vtec only on the intake cam.

Um. It has 8 lobes in the intake cam. 4 low profile and 4 high profile (vtec).

Damn my bad, I'm learning this as I go. I said "one" because I was thinking of the intake cam as in only ONE cam that has vtec lobes. I meant the 9th gen si only has vtec lobes in the intake cam.
