If you are going turbo then don't waste your money on cams. The stock cams work very well with a turbo and you are limited to around 450 rwhp by the stock rods. The turbo alone is capable of going way past that so any extra hp from a cam swap is just wasted. If you ever build a forged shortblock then put in some cams.

Others have stated that it doesn't appear to be a complete kit, but something else definately gets my attention.....
"The exhaust manifolds are available seperately..."
$749 doesn't seem too bad. I have a complete STS twin kit taking up space in the basement just waiting for the time and funds to have it re-installed as a custom underhood setup. The manifolds are probably the most difficult part to fabricate. Being able to just purchase the manifolds like that would make the custom fabrication a much simpler job.

OP just for your information, I had to call Jim yesterday to ask him about something on my setup and I asked him about the TT kit. He said the web site hadn't been upgraded and the kit will work on any 05-10 4.6L.

Ok, that's what I thought you meant about the cams, I just wanted to make sure. I appreciate you guys answering my questions and making the recommendations you have.
And thanks for checking on that for me, Earl. I should have some pretty fat bonuses floating my way soon, so I'm definitely excited to get this project going.

Another question though, what kind of manifolds/headers can be used with turbo systems? I was under the impression that there was a special kind manifold used, but after looking around, I see people using the bone-stock ones a lot.

It depends on if you using a single or twin kit. Most single kits are designed to use the stock exhaust manifolds, or shorty headers, to keep cost down. Twin kits usually use custom made headers to the front because the stock manifolds will have clearance issues turned forward but some kits are designed to mount under the car and use the stock manifolds also.
