My box is going to be 2.5cf and I need to make one port for 32hz and another for 35hz. Eveyrone is so undecided about what to tune the type r 12" for so I will try both and see which I like better. I need to know how big to make the ports to acheive these hzs in a 2.5cf box. Could someone please help me I dont know much of anything about port design.

Gots to know how much port area you're dealing with mang. Then and only then can we tell you the port length. Perchance you want a box design, PM me.

I do not have room to build a vent into the box like the moe lester plans i was looking for a traditional port. I dont know what you mean by port area. All I know is the box needs to be 2.5 tuned to 32 or 35.
