That thread is sick, I think I have gone through it a few times. With modern turbos lag is mostly a thing of the past, and part of the fun is keeping it in boost.
The other side of me thinks maybe just add some 964 Cams to my car and leave it alone... for the cost of a swap or 3.4 build I could nearly complete a nice Cobra Kit.
It's hard, Porsche is the car I have always wanted, not I just need to figure out which version I want my Porsche to be LOL.
Stealthn, clearly your budget and mine are worlds apart.
