RC 440cc injectors: $530 http://www.forgedinternals.com/store/home.php?cat=251
CJM FULL fuel return system: $970
Total cost $5895
APS Single Turbo kit: $5890 http://www.turboperformance.net/bsp/
So lets compare now...APS has a new oil pan which I will say is a nice feature compared to none with the Turbonetics kit. Does it make that big of a difference...well thats up in the air. I haven't seen any actual logged temp difference between the two and I'm not sure if you can fully use the extra quart of oil that it has the capacity for due to smoking issues. Or was that just with the TT kit? Correct me if I'm wrong. That is the biggest pro for the APS so far IMHO.
Fuel system: CJM or AAM fuel system are HANDS DOWN better then the APS style system. I think we can all agree on that.
Turbo included: At this point theres no telling HOWEVER the external wastegate included in the Turbonetics kit has not had HALF as many issues as people have had with the APS internal wastegate actuators
Engine Managment: The Emanage Utilamte has had unbelievable success so far and while the Unichip may be on par (in some peoples eyes) it is diffcult to find and "authorized" tuner for that compared to the Emanage which can be tuned more easily and by more shops
Intercooler: I think its a draw here. Both are bar and plate intercoolers and unless someone has actualy flow numbers here I think we can agree that they are both fine. The Turbonetics Spearco unit has less then 1 PSI drop across it and I think the APS is the same.
Performance: Out of box, no tuning the Turbonetics kit puts down 377 RWHP at 8 PSI. Out of box no tuning the APS kit has put down around what 330-340 RWHP at 9 PSI?
tuned with mods mentioned above at 9.5 PSI with the APS exhaust which is a what $895 option? the APS car according to APS is making what 386-400 RWHP? The Turbonetics car makes 401/418 at 9 PSI. Now lets keep this non-personal and just compare..for the dollars spent its hard to beat the Turbonetics tuner kit with the mods listed.
Edit:
Just to make this EXACTLY apples to apples:
APS 2.5" ST exhaust =$995 + $5890 for APS ST kit= $6885 power when tuned according to APS 386.4 RWHP with 94 RON gas
Turbonetics kit as equipped above= $5895 + Apexi N1 3" exhaust($599 http://www.hopupracing.com/cosoapni35ex.html)= $6494.
Thats a price difference of $391 with which you could if you chose purchase and install the APS upgraded oil pan. If so making the prices equal you get:
APS as equipped= 386.4 RWHP at 9 PSI on 94 ron
APS tuned plus Nismo exhaust ($950) at 9 PSI and 93 octane= 380 RWHP
Turbonetics as equipped= 401 RWHP and 418 ft/lb at 9 PSI on 93 octane
End result similar power with the Turbonetics being slightly higher but easier install, easier access to tuning, better fuel system with more head room.

The T-Netics tuner kit sounds like the way to go if your looking for more power from the kit down the road, right???
For instance, i buy the tuner kit and set it up for about 380-400hp with the emanage, injectors, etc.....then down the road when i get bored and want more boost and power etc.....i go get my block built up, re-inforce some of hte key engine parts and turn up the boost (after a tune of course)....
Is this correct? Is that the main reason to go tuner kit over APS?

I'm pro-tn since I'm going to get the kit 
, so imho tn is better, but of course you can do the same with both kits. I think you are going find alot of pro tn people on here though, aren't they a sponsor on here anyways? APS is a great kit, and the TT was an option for me for awhile. I just have a problem with the hype and hoopla from them. If I had no $$$ limit I'd go crazy with an SFR kit.
Regardless, I think any of the kit's listed are great. They all have their pros and cons, you have to weigh $$ vs. performance vs. whatever else you like to choose what kit is right for you. Just make sure you do it right.
FWIW I'm getting the TN kit because of value/potential/looks/support/simplicity... and the people that I've talked to from TN are awesome.

It really all comes down to what you're more comfortable with. Me, I prefer letting others prove in a system on a $40K car. If it works, sign me up; if not, I'll wait. In other areas I'll choose to take the lead (like setting up a car club) If I fail at that, no biggie.
Many people like to be able to weigh the risk/reward and use proven data able to make an educated decision. The ST's have only been out for a short time and many APS ST's have caused problems. See Tig and Beastie for examples.
The TN kit has also caused issues with the reflash (can't quote screen names, but search on my350z.com). The TN kit with E-manage or equivalent might be a good choice, but only time will tell (and I was tired of waiting
). I wonder how much those stock rods are going to like full and sustained boost at just shy of 4000 rpm? The Vortech cars don't see full boost until ~6500 rpm, so the time the rods see all of the added stresses is MUCH MUCH less with the Vortech. Will this lead the S/C crowd to better engine longevity? My guess is yes.
YMM (and probably will) V.
