the stillen kit does look good under the hood but its function is limited very limited with out a good tune or/and modifications to the kit dont even think about making more power with this kit. its a one shop/stop kit

once you get a taste of power you want more and there is no growth here.
if i was to do over stillen would not have been my choice and thats my fault for not doing more research first.

just as an example the air-water cooler is just barely able to keep up with the 8psi boost. you get a nice hot day and the computer will start to pull timing on you. happened to me. the intake manifold gets hot as hell you can almost cook on it and there is no way in hell the air going into the motor is cooler then outside air NO WAY.

the kit does what it is designed to do and nothing more.

I have been considering going the forced induction route, and considering I only want a moderate performance increase, with maximum daily driveability, the GTM supercharger kit was the leading option for me. (Actually, I spent a while with one of your reps on the phone just a few weeks ago.) However, I have to say this whole thread has concerned me significantly.

I have never seen a vendor get into a pissing match with a disgruntled customer in a public forum. Those discussions are meant for offline, private communications. Could you ever imagine Apple, AT&T, Nissan or any other well respected company berating their customer on an internet forum? C'mon guys; I can appreciate that you have a brand to represent here, but you don't engender a lot of confidence in your professionalism, service and subsequently products by stooping to the level of the same bashers, who (as is obvious from most responses) don't have any credibility here, anyway.

Two things sell - superior products and/or extraordinary customer service. Do your company a favor and simply address these issues a little more diplomatically next time. A simple, "We are sorry you have heard incorrect information about our products. We are unaware of any of the issues you have mentioned, and are happy to address any concerns. Here are some of our products strengths...(boilerplate)." This is how you handle idiots who don't know what they are talking about, and still come out smelling like a rose. This is the reason you don't see successful companies treating future, current or former customers like enemies.

They have a bit of a history together :) Regardless, you will be hard pressed to find a supercharger kit that works as well as theirs. AMNVQ was running a Stillen kit, not the GTM. Customer, no. Previous customer, no. Previous potential customer, yes. They run a business that relies heavily on the Z/G community, disparaging or untrue remarks, or accusations weigh heavy if they don't step in and defend themselves. Just like if someone were to call you out on the forums or call u a troll or say you stole money from them, etc... You would fight to get your name clean.

My car is currently with them and I haven't had issues. Just late email replies at times.

Wow, in reading this entire thread, it seems more like a personality bash than real information. I just had a Stillen SC installed on my 2012 Nismo. I am more than happy with it and so far have had no issues what so ever.
In all of my research I have found a few consistencies in both kits. In almost every case neither make enough power to please the power seekers. You always want more. Both kits have had some issues. In the end, most will try to lead you to a TT solution. There you can get as much power as you can handle. And then those people even have problems because they over power the car and that leads to many other issues.

Here is my bottom line. No matter which kit you go with, the person installing it, and the person tuning it will ultimately be the maker or breaker of your experience. I say (to myself) that 90% of the problems that people report are results from bad installations and tunes. With my stillen, I went strictly with a custom tune and didn't even look at the Stillen one. I went with a top notch installer who has done many of them and has deep race car experience. My result is a good one.

Second bottom line is, I am pleased with the 415WHP that I have. I don't want the car boosted to oblivion. I believe the factory block can only handle so much and I am keeping it in a safe range with good power, fun, lots of smiles, and most of all reliability.

415 WHP is not a great deal over stock, but it is about an extra 100WHP on average. The car does not get crazy when you stomp it. It don't slam you back in the seat. You don't loose control with VDC off.
Its just good pep and a smooth liner power punch and most of it is over 5500 rpm. You will never feel the stillen until your up in the RPM's but its good when your there.

So in a nut shell. Make sure your expectations are in line, and make sure you have a damn good installer and tuner or you will be complaining about one or the other, just like the others.

Actually, I have to say, no, I would not fight in the manner seen here, to keep my name clear on an internet forum. I do not believe that is the appropriate way to handle yourself. This is even more so exacerbated by the fact that I am merely an individual, not a business. I think such behavior damages a tarnished reputation more than redeems it. Superlative products speak for themselves, as will their satisfied users. Hence, the whole point of my post.

I can appreciate, as I said, that they are trying to support their business. Simply, I think they have gone about it the wrong way. If acting that way doesn't turn off other buyers, then great! They have only potentially lost one customer. If other people feel the way I do, the consequences could be far more dire than the damage from one dissenting poster with questionable credibility.

To give the OP the info on my build. I have the stillen kit and can say i like it. I went from 265hp base to 432hp on a custom tune. (same dyno, and close to same temp +1-3 degrees) I have stillens headers and HFC and catback exhaust which all seems to work very well together. I have about 15k on my car with no major problems (also this kit came from RCZ and I think he had it for 10-15K on his car). Only problem is the position of the MAF's (my fix was building a air box to prevent direct air from hitting them. Is their limitations to this kit yes but like anything else unless you stay stock you will run into problems and even stock you can have issues. every car is a little different and will need some attention to get it right. I have plans to up the boost down the road but plan on building the block to be safe. so in short I like my kit, I would recommend it.

as far a as GTM's kit I think they have a good product. I like the numbers it puts down. Looks very consistant. Now if they would have had that twin supercharger when i was going FI I would have bought it just because it looks like a monster under the hood.

Simple fact is do you research and make a informed decision, I personally like a SC over TT due to the fact I like the feel of it and know what to expect when I hit the gas. tt never did it for me but that is me. Here is a couple of shots of what I have done under the hood just so you can see what you can do as far as this kit. It gets attention. I changed the hoses and connectors for looks as well as performance and put on some look good goodies for car shows but basically the kit is the way it came from the factory. good luck in your decision.

Holy thread bump batman!

90% don't feel the way you do or they wouldn't be booming with business. Your looking at this with the blinders on. In today's world, there are some shady businesses around, some major corporations (coughapplesamsungintelmicrosoftcough). GTM is at least honest about what they do, the products they sell, the support they provide, and the defensive position they take. I'd rather be aggressive than passive. Maybe we just think differently. :tiphat:

Gotta go with ole Firehawk on this one.

If GTM hadn't made a statement refuting all of the claims, people would be crying foul that they hadn't said anything.

Lol Kelly, I think I have your headers on my car. The headers are why I went with the twin SC haha.
