Anyways I don't doubt that the JWT kit is a great product but I would've at least liked to see larger injectors. I, too, will be considering this setup, with the addition of larger injectors, once it is more readily available and there are more reviews on it from shops that I trust. In the meantime i have no problem waiting...

BTW, if you move into the "tuner kit" realm, the possibilities for you would be much greater. Despite the fact that most kits offer decent EMS's, none can touch the ones that are available by themselves (UTEC, HKS, EU...). Then you can simply chose the kit based on the best hard parts...

Also, if your pockets are deep enough, there are three companies that offer fully built 5AT tranny packages for the Z. They all include re-worked valve bodies and upgraded clutchpacks... This is what I know about them so far:
SFR: has a core program, at least one member, Tinman, has one. Seems to give a good feedback about it
SGP: no core porgram. Not aware of anyone using it. But SGP does make the best valve body upgrade.
IPT: no core program, but located in Wayne, NJ. Doesn't sound like they ever did a Z before, but seem capable enough. They built the tranny for a 9-sec auto-tranny Eclipce.
Either way you go, be prepared to drop about 3000-3500 $.
P.S. There are 2 different 5AT's on the Z, one has the computer on the inside, one has it on the outside. If you are to use a core program, make sure that they built the right one for you, as these two are not interchangeble...
Hope this helps.

And I don't even understand why is everyone pizzing their pants over the JWT kit, these peanut size turbos seem to run out of breath at about 6000 rpm, Nevermind the fact that it forces you to run stock injectors maxing out their duty cycle. I'm glad that it's the most OEM-like, but have you seen THAT many heavily modded Supras and Z32s that are still using stock turbos? And, just b/c a turbo is small and is able to hit max boost sooner doen't mean anything. The SFR kit can make over 400 whp on just a little more then 6 PSI (and that's with the split second box, imagine a UTEC or the HKS). And that TT kit can hit 6 PSI at about 3000 rpm (all according to the website, if they lie then I'm wrong), so the ability to hit a certain boost level quicker does not necessarily mean that you'll make the power quicker. Not to mention that lower boost means lower heat AND ability to run higher compression pistons, improving the throttle response further. It looks that everyone had to raise to boost by 1.5-2 psi just to compensate for the power lost by going from stock to 8.5:1 comp ratio... I'm guessing to have room for making really insane power, or just b/c everyone else was doing the same... **flame suit's on**

You can run larger injectors, the reason the JWT runs stock injectors is to clear carb certification (which they still are waiting on) unlike the other Turbo kits which pretty much don't give a damn about being carb certified. This of course would limit how much power you can produce with the kit, but if your power goals are 380-400 hp & torque with stock engine & carb cert down the line then you really can't go wrong with the JWT.

But when track junkies install it... Now that's a bit confusing...

I already helped you out. Read post #24. Any of these would suit your needs, once again, if you have that $$ to throw around.

Do yourself a favor and start searching on this site. You will find all the info you'll ever need. Its hard to sum things up off of one thread. In the end you'll figure out what is right for you.

FI can work on 5AT... it might come at a risk... but IMO its a risk worth taking... and hell ... we might even somewhat bonus from the traction problems that lots of the FI Z's are having... They can not seem to grab the ground when shift from the pure power... the AT will allow the car to remain in power between shifts... might help out! I havent been in a 5AT FI Z yet... but wait about a week Mine will be finish from Tuning Factory!! *Shameless Plug*

For only up to 400 WHP, the tranny is fine. Maybe just a simple Valve Body to smooth the shifts. Many folks have used up to this power level with AT. However, if you are looking to make huge power like 500 WHP/550+ FT/LB torque, you will need to take Oleg’s advice in addition to building your motor amoung many other things regardless of which Kit, JWT, APS, GReddy, etc.
Sorry if my previous post's suggestion was a lil' confusing. If you wish to PM, I would be more than happy to help out.

But 400 whp is definately in a safe range. So for 400 whp or less, you'll be fine with a valve body for the tranny and stock motor. Anything above-upgrade, upgrade, upgrade...

NOTE: The Built Motor's stronger parts help incredibly and it is also important WHO and How someone builds your motor that counts. Not all built motors are created EQUALLY!
In addition, the more boost you use requires better tuning and even MORE ATTENTION to detonation. So at any rate, I recommend anyone who is looking for more than 400 WHP, NOT ON THE DYNO, but daily driving on pump gas at higher boost and higher WHP to BUILD YOUR MOTOR regardless of what turbo system you own or wish to buy. Don't get blinded by everyone's claims of huge horsepower on a non-built motor. If they are bragging, they probably haven't lost a motor yet.
IMPORTANT: 8-second dyno runs are so short and loud you may never even realize your car has detonation. Almost everyone can turn their boost up and run the dyno at higher boost and drive away. It is cool and gives you a bragging number, but most can't drive their cars hard or road race them on a 20 minute session consistently at that higher boost without a motor build or simply catastrophe MAY happens. Yes it can EVEN HAPPEN TO YOU.
Think - if you are driving around town on pump gas at a higher boost setting than you should, and decide to drag a corvette next to you at the light and your car detonates even for a few seconds, you will for sure hear it then. Here some slapping of a rod or piston breaking through your block.
VQ35s aren't like the old Z32 or Supra motors of the 90's which could handle much more boost than our current motors. They are lighter today break alot easier. Just a fact we all have to live with and this is why we build motors. It is a safety net that is not a guaranty, yet helps to decrease your chances of something breaking.
You can have APS, SFR, Greddy, Power Ent. Turbonetics, OR JWT, AND I would still recommend you build your motor if you are looking to play with your boost controller more than your Out of the Box system recommends.
My $.02.
