Can it handle it??

I agree, especially bad when it is coming from people who have no personal experience with either option.

I have a 2010 nismo (7000 miles) with a GTM stage 1 SC. I had it installed recently and really like the kit. My only issue was that it took about two months for GTM to send it out, after I paid for it. (I haven't posted the info in the finished build section yet, but will as soon as I have time). I got 390.3 WHP with 323.4 FtLb of torque at 7000 rpm on a Dyno Dynamics dyno (It was 90 degrees that day). I also installed a oil cooler, resonated test pipes, and got a custom tune.
My car was totally transformed by these mods. It is a blast to drive. The SC kit fits the car so well, it almost looks stock. I believe your car gets cut up a lot more with the Stillen kit. As far as reliability, time will tell. My advice would be to think carefully about which kit you pick, do your research, find a good tuning shop, and go for it. A large increase in power will always = less longevity, but I think having a car that stands out from the rest is worth it.

GTM FTW. and yes, i am bias.

What experience do you have to have to recognize junk. It was junk in the 350Z era. I've been around more than enough to know. Seen it first hand.

I have no personal experience eating crap but I know to stay away from it.

The term "junk" is being used in this thread, please can someone elaborate on what exactly is junk about the stillen kit?

The tune that comes with it is obviously not the best tune you can get, they are going after that CARB approval after all so its certainly not as aggressive. People run it never the less and their cars work perfectly fine. Some people have experienced drivability issues (after the car is warm for example), but the same is true for GTM kits as well, its all about the tune there. I personally wouldn't run any unit without a dyno tune but that comes from bad experiences with canned tunes.

The vortech V3 is a great blower and multiple power levels are attainable by changing pullies/impeller. In stock form it makes similar power to a stage 1 gtm, when modified it has made numbers closer to the new stage 2 gtm. The limit to power with this blower is what the engine and IC setup can handle, not the unit itself. Is 400-500hp "junk"?

The intercooler is a very efficient air-water setup built into the intake manifold, this is probably the only "weak" point if you wanted to run big power with this car (more power then the stock block can handle). The compact design makes it incredibly easy to install and no FMIC blocking air flow to oil coolers/radiator. Another benefit is the lack of heat soak when stopped as the water is constantly being pumped through the heat exchanger/IC.
