STILLEN SUPERCHARGER - some questions, please help!
 

ok first off, if i get the stillen supercharger, i also plan on getting dual exhaust, headers, high flow cats, oil cooler, and a couple other things. what are some mods that would help make this supercharger not only more efficient, but more reliable?

my second question, will it be ok to install it on a stock motor? the car will have about 3000 miles or so when i would get it put on, driven pretty responsibly. i have heard of people doing this, but i want to see what some opinions are. if you think i should rebuild the motor at all please tell me what kind of parts and provide me links for them, thank you guys!

:happydance:

I don't know why anyone would select the stillen s/c kit over the gtm??? The gtm's engineering looks years ahead of the stillen kit. The whole kit, especially that pulley and bracket system looks home made. The intake manifold looks like crap too.

i'm a loyal stillen customer, damn right, i've bought a LOT of parts from them before for my 350z and never had any problems and their parts do work, plus their good people, good to do business with.

now, as far as the gtm kit, why have i never even heard of this 'gtm' before today when i've been a z owner/modder since 06? the stillen kit is right around 6 grand, and that's already pushing it for me, how much for the gtm? if it's anymore, i might as well just do twin turbo.....

also, do i need to rebuild the motor at all if i go gtm?

^^^ cuz you never looked past stillen. that is why you have not heard of GTM. The GTM kit is cheaper money wise too. No motor rebuild needed with either GTM or Stillen on their stage one kit. The GTM install will be cheaper then the stillen install too. Only thing i would recomend is an oil cooler which GTM offers as well.

I have the stage 0 kit on my G37 from GTM 7000+ miles on it no issues and SAM is always available if there are any questions no matter how dumb they might be.

I have seen both kits. Been to both shops in person and I would do the GTM kit all over again with out a second thought.

Stillen parts like intakes and sways is one thing but stillen SC's have been a fail even for the 35/350 guys.

My car had 3000 miles on it, I have around 900 miles with the Stillen Kit and it is doing great. no complaints yet.

yeah i'll check into the gtm, so if i did stage 2 what would i have to do? you suggested oil cooler, but i would also need clutch/flywheel.....what supporting parts do i need so my car doesn't break down from the power?

OP, I have the Stillen kit and have absolutely no problems and made plenty of power. (455whp)

Stillen is having trouble with their tune, but if you get the car tuned by a third party then you will have no problems. If you are getting all those other mods you will need a custom tune anyway, so don't worry, the kit works great. Its just STILLEN's tune that is having issues.

At least the ones with the Stillen kit know what 400whp feels like :stirthepot:

FALSE

I know for a fact that SAM can tune his car with all those mods with out ever seeing the car. I know he can do it because he did it with my TT kit. Now I know there different but Sam is that good of a tuner. Run a couple log files with some pulls through out the power band and then you send it to him he looks it over and if there is something with the tune where he can adjust the parameters he does it and emails you back the new one. That simple. Also my car is performing just as good as the ones that roll off his dyno after he tunes them.

Now this might be true for stillen since it appears that they can't get there canned tune to work. My point is why would I buy there kit to have to pay someone else to tune the car. Considering the the price of the kit is to include the tune. I would never pay for the same thing twice.


Like I said I have no problems with stillen but I just don't like how people have not been able to drive there car for a while now, and when they do get to there not getting the numbers they felt they deserved. In other words they paid 6000 usd to have there car sit in the drive way. If people want to waste there money just give it to me and the keys to your car and I'll give them back to you in 7-10 weeks =). Stillen could have prevented alot of issues by just refunding some money to there people and setting them up with other shops to get a customer tune, Mean while holding all sales on any future kits till they got the tune issue resolved. They could have focused on it better and been more relaxed about it, instead of answering 20 phone calls a day asking if they made any results because my car is still sitting in the driveway/garage waiting on you. That is my opinion obviously.

Here we go again.

OP, Do some research on your own. Use the Search!!!!
Threads like this make me want to punch a wall.

:iagree:

ok apparently i don't, maybe that's why i'm on this site, asking this question....so instead of being a smartass how about you help me out? do you think i posted this so i could hear answers like yours, or so i could get help? maybe you don't know anything about it either because you didn't give me an answer

EVERYONE READING THIS POST

do not fight on my posts, all i'm looking for is LEGIT answers to my questions, if you wanna fight do it elsewhere, i hate sifting through your crap and i didn't join this site for smartasses to answer my questions, i joined it because i thought if i put up a post it would get real answers and i would get the help i needed, not a bunch of grown men acting like 12 year old girls

This should help: It all starts here

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...

LatgeralG'z is correct, I am liking my Stillen kit. Sure it falls short of Stillen's advertised gains but overall it is a well put together kit and I have owned Vortech in the past on mustangs and they are darn near bullet proof. Stillen's tune actually is working very well on my 7AT. The only thing I would like to have now is a Transgo shift kit, which GTM advertises as having in stock for the 370Z on their web site. But, as it turns out the the kit will not work on our cars. When I have emailed and called to inquire about the kit as to when it will actually be available for our cars I get no response from GTM.

Thats only because the Turbo Charged crowed has already proven them selfs. Supercharging is a much harder process for the tuners than turbo is. Too bad someone is not offering single turbo systems to help make the price closer to the superchargers price. I really think SC is still a great option, and I know all this will pan out soon. The only thing is I hope we get an engine tuner to really break the VVEL and truly gain for control over the engine. Its going to take a tuner to really throw down some coin to gain this info. Hope to see this happen in the next few years.

and everyone tells me i'm nuts when i say the GTM website needs work.

Hahaha, seriously it does needs work! This time I tried ordering something very tiny which should only cost a few bucks to ship and the website only allowed a flat rate selection which costed more than the item itself haha.

Sam should definitely fix that lol!

Boosted Performance (a sponsor on my 350 z) is looking for an HR and VHR to build his brand new "mid mount single turbo" on. His kit made 408whp and 4xxtrq at only 8psi on the VQ35DE engines.

By the way, the complete kit is only $4,800 for DE.

If you're serious about a single turbo, Boosted Performance is the way to go. Just hop on the other forum.

Those guys on the other forum sucks! They'll pick on you rather than actually try to help you out lol. Just be careful about what you ask.

Sounds like Zilvia, NICO, and a few others that I am a member of. I will check out that company also.............

not me i think SAM's website sucks balls. It is truly lacking.

oooo single turbo. that is what i want to do to my FX

So is this like the STS tuebo just futher up the cars exhaust? 4800 might be a little high compared to the SCs that have redesigned and fabed stuff. Maybe they should do an intro price to.
