Everyone needs to modify a car to extreme levels and then realize that its impractical, reduces their reliability, upkeep and responsibility increased, and worst of all reduces their resale hence losing them money. So I say do it....otherwise you will never understand what a waste it is...heck of a allot of fun. However, a night at the strip club is just as much fun and costs you less....

I hit 300 with my mazdaspeed then pushed to 350 then 400 and at 400 wished I had bought the next size turbo instead of the one I did swap lol...this was roughly a week after hitting 400whp

I personally think these motors are more reliable with a turbo. I've seen a handful of people supercharge the vq37 and it ends up blowing very soon. But seen turbo cars pushing 600+ hp with no issues. World record for whp on a vq37 on stock everything is like 819 whp~ so far.

This. Only do it if you are doing it for fun and plan on keeping it.
OP: If you do it right, and treat the car right, I think you can stay reliable. There are plenty of 370zs running stock motors with tens of thousands of miles turbo or supercharged (more turbo). I have never had the Stillen supercharger, but I have the FI twin turbo system and have read all of the threads pertaining to both, as well as a single turbo BP system. If I were starting from scratch all again I would get the BP single turbo kit. It is far easier to work on, and can make the power of the lower stage twin turbo kits (~600 WHP with supporting mods). The Stillen kit is just too close in cost to the BP kit for not netting the same HP. That being said, there is a member in 370z that offers an update to the stillen kit to make it more reliable, and in turn, makes more power. It still isn't worth it from my perspective over turbo though, unless you just HAVE to have that linear power increase. JWick over here has the BP kit, and a few others here in the forced induction section have the Stillen supercharger. Only a few of us have the FI tt kit. I have no personal bias towards any of the kits, just seen far too many supercharger issues compared to turbo.
TLDR: if you are satisfied with ~600 WHP max ever, get a BP turbo kit. They are easier to work on, you can install yourself, and they are cheaper than a TT option. Superchargers cost nearly the same for less power, and less reliability unless you go air to air cooler.
EDIT: Forgot you are 7AT. The 7AT needs major upgrades to handle more than about ~4XX WHP. Not an expert on the 7At though, someone else would have to chime in. Also forgot to mention the AAM TT kit. TTV36 has this one I believe, so you can get his opinion on it.

If you go FI, go with a turbo kit, superchargers are neither here nor there and since you have auto - it works better with a turbo kit anyway as it will keep boost longer and switch gears faster than with a manual. The problem with a turbo is that it needs a lot of other upgrades and supporting mods starting with the transmission which needs to be beefed up. Reliability on a turbo car is not what it is with a stock car and parts will wear out faster but it's not a huge deal, motor is solid up to 600whp.
Definitely not worth it if you ask me.
- Cost to rebuild transmission - 7AT is made of glass
- Engine under too much load - reliability issues
- Too much work with minimal ROI (Torque wise specially)
- A lot of extra heat and tight spaces to deal with
- GTM is out of business - no aftermarket support
- Stillen's aftermarket support is a hit or miss as well, tuning their kit is a pain due to unequal flow into each throttle body, all it takes is for one cylinder to go lean before the engine craps itself
