My Vortech Build
Update 9/27/2012:
I decided to swap my Ark Grip exhaust for a MD TDX2 Shockwave. Wow, what a difference! I should have just gone with Motordyne in the first place. The Art tp's and TDX2 are a great combo. I no longer have the pesky rasp and hissing noise I was getting from the Ark pos X-pipe. You can tell they put alot R&D into this exhaust. The built of this thing is amazing all way up to the V band clamp. The sound is ecstasy to my ears and piercing at WOT, lol. I decided to retune to maximize output potential. See last dyno chart below. My tuner pull it down about 5800rpm becuase it wanted to keep my tq below 390. At my next tune I will have Rob keep climbing as long as it safe and there is no knock all the way to redline.
-----------------------------------------------------------------------------------------------------------------------------------
Update 6/29/2012:
I blew out my Fast Intentions HFC's, so I decided to install ART test pipes and go from a 3.33 pulley to a 3.25 pulley. The Art tp's are freaking amazing. I was surprised that the sound was slightly louder but more menacing than my HFC's. The gas fumes are almost non-existent, a big plus for my family. I highly recommend these to anyone going this route.
Rob @ ZCG did a great job on the tune. I did loose 1psi of boost with the arts. Here is my before/after Dyno chart.

Your thoughts on my Vortech build...
Installing on a stock engine that was replaced because of the OC issue in 2009. New engine currently @ 25k miles stock dyno from ZCGarage @ 227HP/219TQ
After dyno, I installed the MD 5/16 spacer and ARK v2 TD exhaust. I will know what kind of numbers I got from these two mods on the before and after dyno run.
Decided on the Vortech becuase of the carb stamp on the blower. Hopefully, it will help deter any piggy action or even the possiblity of getting Ref'd here in the Bay Area if i get pulled over and asked to pop the hood.

What are your goals after you build the block? I only ask because it may be easier to go with a larger injector than the 750's they are plenty for the 3.12 pully and stock block but past that you might run into some issues later on, and it gives you some room as far as injector duty cycle later on too. Same with the 255 pump, i know that its plenty for the stock block but I might go with the Aeromotive 340 pump, its not that much more expencive and its cheap insurance that you wont run out of fuel later on, just trying to save you from duplicating work lol. I'm going through that with my car right now, put in a 255 pump and 880 injectors and will probably be going to 1000's and the 340 pump 
Other than that the list looks pretty solid and I'd deff be interested to see how the install goes and what kind of numbers you put down.

ya, if you're planning on building it later down the road you might want to use the larger pumps they have on the market. I ran out of walbro around 451hp on a DD dyno. That supercharger eats fuel like crazy because of parasitic drag.

My goals are to be at or around 550whp/450wtq with the short block build in the future.
My tuner actually recommended the 720cc. I do appreciate all your suggestions. I know when I’m ready to achieve my goals I’m going to have to buy and upgrade parts. I will resale what I can.

Id be suprised if the si trim carb number matched to a 350z. However anything aside from a full vortech kit technically could fail you on a visual inspection. It all depends on how detail oriented the smog tech is when inspection time comes

Really?!...I had an SI trim blower previously, and it didn't have a CARB number on it...I've got to see it to believe it...
But it's certainly possible that the SI trim blower you have is for another car; I am almost positive that if it does have a CARB number its not for the 350z/G35...

stand alone ecu's have far superior tuning ability with more features that the stock ecu does not include. You add features and there is more potential to drive better. My car drove better than stock when i added a haltech and had it properly tuned.
that being said, you have to use what is best for the tuner.

I just got off the phone with my tuner. So he wants to upgrade the wheel only and keep the same housing thus keeping the carb number in tact for the G35. He says he has gotten great results on other cars with this mod. It makes power and boost sooner.
I'm going to have to go by his experience on this one.
I'm just waiting on some parts and my custom pod to arrive by end of this week. She wil then be ready to go in for surgery.
