Thanks for all of the great responses guys. I had already purchased a complete 3.3 turbo intake system for what I thought was a pretty reasonable price of 900 bucks. It included the complete intake, intercooler, turbo, etc... So based on my goals I think that a factory turbo intake will get the job done. My car only weighs 2300 pounds so making 500 HP at the rear wheels is not really necessary. Already with the 3.6 most people I know wont even ride in it any more. I would be thrilled to death with 400 HP.
I am going to use the factory manifold with a haltech efi conversion. I wont run more than 1 bar but I might run around 8.5 :1 compression. I will probably do all this on a 3.4.
If it hits around 400 hp I will be thrilled.
