Unless there is any other 3,3 advantages (besides the more heat resistant but worse flowing heads) I think I'm going for a 3,2 engine then.
Is boring out the 3,2 cylinders really as good a solution as changing for aftermarket cylinders? Would have thougt that it weakened the liners to much, but then again as I wrote when I started this post.. I dont have experience with Porsche engines. So I have no idea how much is regarded safe to bore the 3,2 cylinders..?

I dont know how you got that to be my quote, but I didnt say that.
I believe if going with bigger displacement that you should just buy new mahle cyls, not that JMA- RUF is wrong in suggesting that, its just not the way I would go. I also believe that the N/A cyls have diffrent cooling fins than turbo.

I would go with the 3.2 as well as: Rods, Pistons, Cylinders, Haltech, and 20 PSI...

Goran, come on, do you think that is something that I would say after the abuse I put my motors through?
