Nutsid,
I have no interest in arguing the accomplishments of over 20 years of research and trial an error on the 13b, and over 30 years on the 12a. A few people have experimented with the Renesis stuff, but it's been nowhere near on the scale of the 13b or 12a. In fact, in basic design, they're both damn near identical in functionality, so a lot of the same porting concepts carry well between them.

So you can say what you want, but until the Renesis gets the same attention as the other two, your point is rather unproven. The design is sounds, and if you're that hung up on 4 port design, then there's a Renesis for that too.

What I think needs to happen is more investigation into the irons, and their overall use / effectiveness, and a possible standard modification / redesign. The engine is far from ineffective, and to say that you're better off swapping a 13b-anything simply because "this one guy, that time, got like... 800 HP from this motor" is a waste of money and resources. If your goal is 600+ then you need a 20b and be done. Otherwise, you cant justify the expense and time on an engine swap when you yourself said that people have gotten the Renesis engine up to 500+ HP. It's cheaper to boost and tune an already owned / installed engine that it is to start from scratch, and that's not debatable due to the fact that, not only would you still have to buy all the FI accessories for the new motor, but you'd have to buy and rebuild the new motor, fab mounting brackets, most likely a new transmission, stand alone management, etc. You could never justify the added cost to me.

rebuild kit: $1000
Bridge Port: $500
Tuning: $500

custom super charger setup: $1500

For $3500 I can make over 400 WHP in my car by doing most of the work myself, and for most people that's more than sufficient. Like I said, if you start getting into the 600 HP range in terms of goals, you're better off going 20b, so a 13b swap makes no since.
