Blueprints??
I hate to ask because I know the answer is somewhere on this forum, but I can't seem to find it. Are there any blueprints/ Schematics of the 13b NA and 13b Turbo motors. I'm looking for Highly detailed pictures or something like CAD drawings.

I want to see how the fifth and sixth ports work and operate. I'm mainly trying to find out what would be better preformance, a turboed NA or a Build T2 motor. There would probly be diagrams in a haynes repair manual but i haven't gone and got one yet.

My thinking is that 6 ports flow more air than 4, Im guessing it would be like going from a Stock head to a Heavy port and polish on a piston motor. im just getting my feet wet in rotarys so trying to learn before i start buying parts and stuff.

it's easy to fall to the tempting logic of 6 ports flow more than 4, but the best thing you have going for you right now is the fact that you recognize that you are new and you are asking questions. unfortunately, it's just not that simple.
that said, there are a few threads around here that discuss this, i can't think of one off the top of my head right now, but they are here. anyway, keep in mind that the 6-port NA engines have a few peritnent differences that make them less than optimal for a "serious" turbo rotary build. i put serious in quotes because i'm NOT saying they can't perform well when turbocharged.
i'm not sure just how much detail you want, but there's port open/close timings on here (rotarygod posted them, in fact there is a thread currently on this page that contains them). as far as photos/diagrams, i don't know, but maybe start with Paul Yaw's site. i think i remember him posting flow numbers some years ago. if i recall he was illustrating port work and what you may think would flow well versus what actually flows well. you can also look at rotaryengineillustrated's site, if you want more basic diagrams.
hope some of this was helpful to you.
