which header size?

[shahram]

I am finalizing my Carb conversion project and need to figure out which header size (inside diameter of primery tub) to take for my 3.6 engine.
It is a stock 993 3.6 engine but with PMO 50 carbs and direct ignition.
I don't need heat and was thinking about Dansk, Bursh or something like that but wanted to consult you guys before I order the headers and find out they are to big or to small.

check out rarlyl8 headers, just tell them what you have and what you want and the will make a great set of headers.

1.75" OD ~30" primaries, you can get buy w/ 1.625" for street and occasional track use, 1.5"OD for street use only these will kill top end

rotating collector is best, size is unimportant if muffled

Great, thanks Bill & James. I have a set of 1.625 laying around and will go with that for now. The car is for street use and maybe 1-2 DEs in the year.
