Best mods for auto Z?
I have a 5AT 350Z and already have Injen CAI and Greddy EVO exhaust. What mod should I get next? I'm looking for a bigger boost off the line.

Go for the Motordyne XL Plenum Spacer. There is currently a Group Buy going on. I have a G35 Coupe 5AT. The Plenum Spacer made a "real" difference in power and acceleration. Search the various threads and posts on this and G35Driver forums for dyno results. It performs very similar if not better than the Kinetix and Crawford Plenums for 1/2 the price. It is a fairly easy install with the best customer service from Motordyne (Tony). I believe it is the "Best Mod" for the money.

zmego1985, I like your choice of mods.
Yes, a valve body and rear end(Nismo,KAAZ or whatever) along with a manual final drive gear makes a noticable "off the line" improvement. I thought about gettin the 3.9, but the SC already makes too much torque down low.
Another good "off the line" mod would be some rims and tires. With enough rubber, you can minimize your burn outs and put the power to the ground instead of up in smoke
Try fitting some 295s or 315 tires on.

Torque Converter/Stall speed.....
".... One of the jobs of the converter is to act as a fluid coupling from the motor to the transmission. Another, and a very important function, is torque multiplication. What remains is stall speed, a very misunderstood term. Stall speed is directly related to the amount of torque your engine produces (the greater torque, the higher the stall speed). For example, a converter with a 2800 to 3200 rpm rating might provide approx. 3200 rpm of stall speed behind the big block making 500-plus lbs of torque and in a small block with less torque it's possible to only have a stall speed of 2800.......
Stall speed is a term used to describe the rpm at which the torque converter transfers the power from the engine to the transmission. There are different ways to test stall speed. "Foot brake stall" is when you press the brake pedal and then press the gas pedal. When the car doesn't go anymore or the tires start to spin that is "brake stall". (DO NOT TRY THIS! THIS MEASUREMENT IS MEANINGLESS AND POTENTIALLY DANGEROUS TO YOU AND THE TORQUE CONVERTER!) "Flash stall" is when you, from a dead stop, press the gas pedal to wide open throttle (wot). Watch your tach needle, you will see the needle jump to a certain rpm, that is "flash stall". A drag racing-style trans brake will give you closer to the true stall speed of a torque converter....
Theoretically, for maximum acceleration the stall speed of the torque converter should match the peak torque rpm of the engine. A good explanation for the way it works is this: when you go outside jogging you start to breathe in and out faster and harder. Well the same thing goes for a performance engine. The engine is breathing in and out harder and faster, at a higher rpm. If a high performance engine makes power at a higher rpm, then a higher stall speed torque converter is what you need to put more power to the ground quicker...... "

I think I may be swapping my 3.2 for a 3.5 final drive. I am really interested in getting the Torque Converter and Valve Body upgrade.
How much are these two upgrades and where can I buy them?

valve body is 800.
tc should run around 650.
install on both items is pretty intensive. with purchase price and install cost... plan for at least 1000 per each of the two mods.
