There's a search button up there, just type in Stillen Supercharger and see how many threads come up. People have done it, stillen themselves have answered endless questions on the topic too. This site is very resourceful which is why I'm on it (even though I drive a G37)

And you'd be fine with a stage 1 on a stock motor, a guy managed to brake the CV joints in his axles though from a few hard launches, but with reasonable driving you should be good. You just need to make sure you'll get a good tune.

Or just buy your kit from Stillen, then tune it @ GTM

Best of both worlds :tup:

Did you ever join a 350z forum? If you did, you might have came across countless threads about Stillen SC's and how they, umm, how should i put it, on how they are inclined to be looked down on.
:hello:

GTM is one of the biggest and well respected players in the industry!!!

Here we go!!!

This is the reason threads with someone asking for opinions turn to!! Op again research and once you decided what your going with post up useful info to share with everyone. Instead of posting loaded questions, that most here know are going to be subjective to what side of the fence your on. You seem to think you're the first, and that this is a new site or something. Today it's you tomorrow its someone else asking the same question. Like as an example what type of oil should I use? Some of us have been here a while, and grown tired of repetitive question because people seem to not want to do their homework, and just want to cheat and post threads asking Question and want opinions. Welcome to the Internet!!! Opinions are what your getting so don't start on people giving them to you.

Welcome to the Forum!!

Simple statement of fact. There have been no complaints from GTM customers about their SC. GTM has not had to revamp their tune 5-6 times. GTM is cooler then stillen.

Stillen has failed to produce the numbers they advertized. Failed multipul times to fix tune issues. Have a history of producing crap SC's for the infiniti/nissan market

1) if you get stillen supercharger, be prepared for no warranty, and you will require a custom tune. minor issues SO FAR with GTM, who knows what will happen later on. it's forced induction, you're rolling the dice no matter who you go with. not quite sure why you want to upgrade headers + hfcs, think HFCs are good in NA setups, keep stock cats if you want to keep higher pressures, but i might just be drunk and not thinking straight.

2) you're rolling the dice with forced induction. yes, it's been installed on a stock motor before. none of them have blown up..yet. but forced induction means the motor is seeing more stresses, no matter how you drive it.

there, my opinions. please, PLEASE just use the search next time so we don't get a failtrain going...

Useless posts removed from this thread. I want to remind everyone PLEASE reply professionally. This is not my350 or other Z forums. You can stay here(on the forum) if you can reply professionally. Name calling, childish bickering, etc will earn you time off from the forum (as warnings has been sent out last night).

Thanks

Few things i wanted to throw out there:

1. both kits are fairly new with development ongoing on both so if you are looking for as few problems as possible it may be advisable to sit on the fence for a while until things smooth out.

2. the STILLEN and GTM die-hards are like ford and chevy guys throw them both in a room (or a thread) and a fight is bound to break out.

3. on the old Stillen 350z kits, the new kit is a whole different beast, the old kit was terribly undersized for guys that wanted more power than the kit was rated for as the blower needed to be small to even remotely stand a chance of fitting in the hood with only minor alterations. They have learned from the old kit as the new one has a big centrifugal vortech unit.

4. If you decide to go TT i would say the GTM TT is the way to go as it can be ordered in a turn key kit that works fine where as the greddy can't be, and it sounds like you don't want more problems than you need.

5. if you want more power, my opinion is in favor of the stillen kit because vortech blowers are cheap to upgrade, the unit that comes with kit can handle more power than the gtm stage 1 unit, and when you go nuts with pulleys and exhausts the supplied tune isn't going to be an option either way as for safety you will want to have it done on a dyno anyway. get a meth injection system for higher pressures, make sure your kit comes with an intercooler, but in all reality if you want balls to the wall power just go TT because centrifugal superchargers fail completely when paired up against a properly designed TT kit I.M.H.O.

6. if you care about looks they are 2 different flavors stillen has that "look at me I'm totally not a stock engine bay" thing going and gtm looks like you added a CAI when you pop the hood.

I would seriously weigh the options of both kits as they are designed for 2 types of guys, and for better or worse they are both very competitive

Well stated. Still waiting for the end state of the SC options before I decide whether to go with an F.I. application. For now, it looks like N.A. w/ bolt-ons for me.:shakes head:

THANK GOD, AK runs this and not the people for My350. You are the man, that is for sure, and I cant stand the other forums, really bad people running them.

Nothing wrong with staying N/A until everyone figures out what they are doing. Stillen needs to address the million and counting complaints minus RCZ. GTM needs to address the issues with their S/C kit in its initial stage when matched with free flowing aftermarket exhausts.

OP, I agree with those who said please use the search button. If you don't have the time or patience to search call Stillen directly and ask them your questions.

Props to AK for keeping it clean but how about enforcing that "search first before posting repeat questions" precedent :tup:.

You don't even need to search! GTM and STILLEN thread is the hottest topic for the past half a year and it's staying on top of the force induction page.

Yes, listen to weiboy. There is enough verbal warfare in both of those threads that will give you all the info you need.

However, if you want an opinion. Get the GTM kit.

My Stillen kit is working great too, I am happy with my kit! There is more than one Stillen kit working great. OKC370Z is liking his kit as well. Just do your research and make your own choices. They each have there pluses and minuses

Stillen is in the process of providing engine warranty for the supercharger. Your point on engine blowing up with forced induction is mainly a thing of the past. The engine in the 350Z and 370Z handles it greatly and unless used weekly on a track and provided that the normal maintenance is done correctly, the engine will last over 150,000 miles...

Of course you may have to change a few engine part but you may have to change them on a poorly maintained stock car also...
