Thought the general crowd might be interested...
In another high HP TT C5. I built her up in my garage with my own hands, but with plenty of tech support from the forum's resident LSx/TT/tuning guru RoadRebel. The buildup included the removal of the factory motor, installation of a forged bottom end, heads and cam, fuel system, etc. Specifics below.
2003 Z06
Mods:
TTiX Twin Turbo
Tial 50mm BOV (and the custom TTi pipes with the BOV delete on them)
ECS Forged 346
ECS Fuel System
Mototron 60lb Injectors
Textralia twin disk clutch
Dr. Phil / RoadRebel Turbo Cam (very little lope, extremely streetable)
WCCH LS1 Stage II Heads (dated heads and technology for sure!)
Custom front-mount oil cooler
Dewitts Radiator
Iforged Classic 18/19" wheels, black center
No cats
***** FACTORY Z06 Ti EXHAUST *****
Around 650rwhp, 630rwtq. Actually made some higher numbers (as high as 664rwhp, but tq was only 626 on that run). Once the fuel curve was more appropriate it backed down a little bit to 650/630 at the wheels.

Chart:
This is on low boost (9psi). I expect to go up to 15-16psi soon.

Awesome job and excellent numbers. Congrats on a job well done! 
I have considered going TT rather than SC if I decide to go FI but haven't made my mind up. The KB blower and the new upcoming smaller, more efficient Maggie are very tempting.
How's the low end feel on the street? Any reviews you can share yet?
Nice going and enjoy!

filmelf, LowFlight, thank ya 
Chevy Guy -- I mentally added all the parts up and the number wasn't "that bad" -- in the $20K to $25K range (plus the car off course) once you add up all the pieces. Major expenses are as follows:
TTiX Twin Turbo - Around $9.5K
ECS Forged 346 - Figure in the $4K to $5K range
WCCH LS1 Heads - Around $2K at the time, much less now
ECS Fuel System - Around $1.8K
Textralia Twin Disk - Around $1.2K
Trying to think if I had anything else big $$$ wise in to the car, but that's about it. I did the install myself, which I figure would be another $2K to $3K on top of that if I went to someone else.
I think that's about the going rate of an LPE 650TT install unless they lowered it, but of course this thing will probably make 750rwhp when I'm done with it (thanks for the vote of confidence Nouman, but I think once I start pushing hard boost each pound will be worth a little bit less and backpressure may become an issue against the soon to be installed cats, so 750 is the target)
The parts have a warranty on them from TTi but of course labor on warranty removal would be my responsibility. No big deal, the lift in my garage helps out on labor.
Patches: Thanks, and YES! Plenty of personal experience to share here on drivability of the car. Heck, just took my girlfriend for a ride and SHE was impressed. That's hard to do. This thing has an awesome bottom end, you don't suffer from lag at all. I can see a few pounds of boost at light/part throttle which makes the car feel crisp and responsive. Full boost hits somewhere just before 4K on the street at WOT so it's not as hard hitting as the early TTi kits but the top end has much more potential. It's not the cheapest way to make power but the torque is so much fun

Thanks guys. Great thing about turbos is they are quiet, quiet monster power adders. If you like stealth, but killer power, TTiX is the way to go.
