Sup guys, so I've gotten a wild hair to stick with my guns and go FI. I did a lot of research yesterday on turbo kits etc. I looked at old threads and got a good idea on what I'm getting myself into, but since this is a HUGE step and commitment, I want further input from experienced people.
I looked at old APS TT threads and the general 101 questions and things to know for FI, but nothing quite put the thumb on the issue if you will.
So this is what I've got as a wish list (that I will get in the next year if things go like the should): I'm going to get the APS Premium ball bearing TT kit, the APS 2.5" True Dual w/ metallic HFC, along with a Kinetix Velocity Manifold. I'll be purchasing all of this from Z1 Motorsports, and have them do the install/tune.
Now I only plan on running 8-9PSI boost for longevity issues, plus 400-430whp is plenty. I do not intend on getting a boost controller either. What I'd like from you guys is to help me fill in any blanks I may have left off to make sure I keep my engine running for as long as possible.
I understand that getting oil coolers and larger oil pans are a good thing, but how good are they? Is it worth the extra investment? Do I need to improve my stock radiator to help cooling as well? What other improvements are needed to keep the stock block happy?
And lastly, I've read that the APS turbos are the things that give out first on these kits, for the people that have them, what issues (if any) can I expect from this kit?
For one, I would go reconsider another kit. That's just my opinion. Two when you go twins a larger oil pan comes with almost every kit. Three go with a Dual 3" exhaust if you are set on twins. If your going to jump in FI do it right the first time.
Oh and just get a 3/8 or 1/2 intake spacer it will be better and cheaper then the Kinetix intake unless you are going for looks.
Do some research on high flow cats some are better then others and some fail much faster not sure on the brands. I never ran cats just from reading others experiences with them on this forum...
Stock radiator is fine for DD unless you like to drag or track the car all the time.
ya no sense spending that much money on an install, when you can just go with a single or a vortech for much cheaper and much easier to install. A flash tune with osirus and a HPX MAF or a UTEC would be your 2 budget tuning choices.

no doubt for what you are looking for a single turbine setup will be what you'll need...plus the turbo will spool up faster than most twins depending on what size turbo you get
Alright so I looked a bit more into the FI, and going off suggestions I revised my set up. I'd also like all of your opinions, good and bad on what I'm doing.
So I'm switching from TT to single (cost to power ratio is better for what I want with a single) and I'll pick Turbonetics (which I'll purchase from Forged...and is an hour away from my parents' house). I want to keep the Kinetix Manifold, it looks good and may just add that much more to the engine, but I revised my HFC's (Berk) and Exhaust (Altered Atmosphere 3"). I'm not 100% sure on the ECM yet, and will probably discuss this with Sharif or whomever @ Forged when I go to purchase the Turbo (leaning towards UTEC, since most ppl have it and it's affordable).
It goes with out a doubt that I will be purchasing oil coolers/oil catch cans, along with a new clutch when I get this set-up, along with other things like plugs and coolant hosing.
Well that sums it up for now...thanks for all the input guys.
I think so far there has been VERY BAD advice in this thread.
First of all, unless you track your car (roadcourse) you won't need an oil cooler or an upgraded radiator @ 400-450whp.
Second, I know the Powerlab single kit is all the rage right now (price and the fact that it's pretty new are large factors), but single turbo kits of V-configuration motors are typically a very tight fit and you end up with heat in places that it was never meant to be. Not to mention, I don't care what single kit you're running it's not going to have the spool characteristics of the APS twins. It's simple physics.
I've had my APS twin kit since the spring of 2005 (two seasons with the stock motor and then built my motor for more power handling). It has been fantastically reliable and I've watched other members go through numerous kits in the time that I've had mine.
As far as stock like build quality, you really can't beat APS. Their customer service and support leaves A LOT to be desired, but I've had ZERO issues with any parts of my kit, so I haven't had to deal with that.
The only issue with the APS kit is power potential, I'd be hard pressed to extract over 600whp out of my setup with the APS twins, but if you don't plan on building for big power, (I prefer to actually enjoy my car, not have a temperamental 600+whp dyno queen) the APS kit would be fine.
Don't even get me started on centrifugal S/Cers for the VQ.....
My advice for a stock motor 400-450whp build done the RIGHT/MOST OEM way is either a Greddy TT kit or an APS TT kit.

Stick with twins is my opinion but I might be biased (I love my Greddy kit, fun as hell).What did your installer/tuner suggest? You did ask them right! If not start there.

its funny how a few bad inputs can put this thread from good from your research to bad in no time

Man there's some really bad advice in this thread.
You won't get anywhere close to spooling as fast as the APS TT kit with any single kit, it's not even in the same ballpark. WTF kind of advice is that and where did anyone get the notion that any of the ST kits make significant boost as quickly as the APS TT kit lol.
Centrifugal SC? A 430whp Vortech 350z will get absolutely smashed in a race with a 430whp ST or TT Z, with the TT having a vastly flatter powerband than both ST or Centrifugal SC. Area under the curve is so heavily in the TT kit's favor over an SC 350Z it's not even worth discussing. TT wins, hands down.
3" True Dual for a 400-430whp car? Get real. Totally unneccessary.
Please do not get a TN ST kit. You will regret it as most other people on here who made that mistake did. What a half arsed kit that is.
Pay half the price, get half the quality and 5x the problems.
Oil cooler and radiator are unnecessary unless you plan on either track days on road courses or doing lots of top speed blasts and being under boost for significant periods of time (those parts are never a bad idea, but completely unnecessary for a car that's just driven around on the street or drag strip).
Greddy TT or APS TT is definitely the way to go. You did some good research and then got steered in a really bad direction by most of the posts in this thread. Rethink your rethinking, and stick with the TT in my not-so-humble opinion.
