it sucks unless you live in a state like california

imo it may not make the same power as the gtm kit and it may have more problems, but at least its legal and if someone had to take it to a ref to get it inspected, it will pass

i know some guys with illegal turbo mods here and even though they make more power than the guys with legal mods, every time a cop passes by they freak out vs the guys with legal mods, they dont worry because they know they are legal
plus you can always make power different ways, NOS being one of them XD

2013 Sport touring Stillen Supercharger install
 

So the car is home and the SC works. Last dyno pull on the Dynojet produced 395 WHP and 286 lb-ft of torque at 68.5 degrees on what Stillen calls a "safe" tune.
Pre-install run with a stock set up adding only a Nismo exhaust ran at
275 WHP and 231 lb-ft torque at 68 degrees.

This amounts to a gain of 120 WHP at a cost of $8200 total with installation.

According to the mechanic at IPS Motorsports the Blizzaks (275/35R19 Bridgestone Blizzak LM-60) are heavy at 30lbs and produce a significant limitation on power of as much as 2% in comparison to a performance summer tire such as my Continental ExtremeContact DW 285/35ZR19
99Y SL at 27 lbs. That would put output at roughly 402WHP with the summer tires.
Maybe some one can weigh in whether they agree with this theory.
The car drives properly. Not overly loud under the hood though I can hear the turbine whine over 4K and the power really hits at about 5K.

My only issue now is the tune is off just a bit in that when I coast down from over 30mph with the clutch in or the car in neutral it stalls every time.

I will work with Stillen this coming week to get a new tune changing only the idle settings and reflash the ECU myself.

Stalling after Stillen SC install
 

One week in, I really do love this FI system. The car is effortlessly more powerful. However, I am still dealing with the stalling problem.
Stillen now says it has to do with air turbulence at the MAF sensor.They make a deflector for the kit that was not installed by my installer due to a "fitment issue." I have been asked to run OSIRIS in the car when I am driving to get readings when the stalling occurs. I will do that this weekend, or possibly today.

FWIW, I have heard from more than one person and from Uprev themselves, that the injectors that come with the Stillen kit are undersized.

Upgrading to 660cc injectors and re-tuning supposedly lets the tuner get a lot more power out of the car.

A local guy here was told by Uprev (he tuned down in Austin @ Uprev) that his injectors were @ 100% duty cycle on the 'recommended' tune from Stillen. Which is baaaaad.

Thanks shovelman. I will look into this. Has anyone else here heard a recommendation for increased flow fuel injectors with the Stillen SC kit?
Are you recommending this as a way to get more power from the car, o as a way to stop the stalling problem, or as a preventive measure against future problems?
Thanks

Since this is my daily driver, I agree with this. Can anyone identify what the base cost of having this completed runs? I'm guessing about 8k?

$8800 for me, but I paid full price for my kit from Stillen, you might do better and the install was high as I was the first 2013, so 8K seems doable.

Nissan370, when r u gonna tell everyone the great new news about ur FI kit??

I recently got my stillen supercharger. 408whp and 305 torque. Dyno numbers also vary with ambient temp. These numbers were at about 75 degrees with 50% humidity. I also am stock except for supercharger. I cant wait to get a hfc and cbe. With those i'll be getting in the high 400's and mid 300's with torque.

ya i will post it in the for sale section
going to be selling my stillen kit

complete stillen kit with 600cc injectors/255 walbro fuel pump ,cog pullies and 9lb pulley

in a month or so
i ordered the s&r performance top mount turbo .:happydance::happydance:

only thing thats needed is a custom tune

How much are you thinking you'll ask? How many miles on the kit?

my kit has less then 3k on it i had the kit put on in aug 2011 35k on the car i now have 38k on the car
most of the low miles was because i only dive my z 2 times a week and all of last summer mar 2012-aug 2012 i was having a new motor built

other then that no problem with the kit
i will be selling 4.5k obo

The car went back to IPS over the weekend to sort out the stalling issue. The shield that covers the Air flow sensors had to be modified to fit the 2013, but when put in place the stalling was nearly completely gone. IPS also slightly modified the tune to increase fuel flow at idle. The car runs perfectly now - no stalling. I am very pleased.
Of note my last tank of fuel was 15.85 gallons topped off. I got 290 miles out of that tank The trip computer read 43mph average.
The trip computer also read 28mpg for that tank, but 290/15.85 = 18.3 mpg.
So don't trust your computer to tell you your mpg with the Stillen SC in place, it way overestimates.

Irondoc it sounds like your pretty happy with your car. I have a new 2012 with 1800 miles on it and I'm thinking about pulling the trigger on this SC. I read the entire thread and there are many opinions and issues. It seems though, that most are not happy because they want more and more power. Thats great, but I want to maintain the factory block, and it cant handle much more than 400WHP for any length of time. I live down in Texas so summer heat may be an issue, and I have to check into that more. But if I can get around 400WHP out of this small car, I know I will be happy and stay alive a few more years lol.
On MPG. Who cares? If your putting the power to the car and your spending the money for it, who cares what the MPG is.....
Like you, I want a clean new car with much more than factory HP in a new car package. I will keep an eye on your feedback regarding your install.

Such a misinformed post. You have a lot of reading to catch up on. Power n longevity depend on how good your tune is from your tuner. There r guys out there with 500hp+ running for years just fine with no problem. Read up n research...:shakes head:

It's basing its calculations on a smaller set of injectors. Any time you change the injectors you throw off the mpg reading. I get around 18 mpg combined driving and my display shows almost 30 mpg. I just switched the display to outside temperature. I'd love it if someone figured out how to reprogram the car to account for the larger injectors so I can have it work again.

[QUOTE=dansracing;2135224]......On MPG. Who cares? If your putting the power to the car and your spending the money for it, who cares what the MPG is.....
Point to the MPG calculation is that Stillen has made claims of improved MPG with the SC, and others have debated the issue here, so just posting my real world observation.
The bulk of what I have read here suggests that our engines can safely handle outputs up to mid 500's whp. As you stated, several of those running TT kits feel the Stillen SC does not provide enough of an increase in power. However my car is now at 395whp (Dynojet at 61 degrees F) with snow tires with no attempt to improve the tune for power.
Others seem to have achieved up to 440whp with additional tuning. Then there is of course the possibility of a 9 or 10 psi pulley (more?). I do not imagine I will want much more than what I could get from tweaking the Stillen kit down the road. Maybe someone who has truly maximized the Stillen kit can comment on what they have achieved.
Other Stillen advantages
1. 50 state CARB legal
2. 36 month - 36,000 mile warranty.

thats some serious $ for as problematic as this has been for you; which I'm sorry to hear. this is exactly why I've stayed away from this option so far. If I dish out 8k, I expect to pick up my car working perfectly.

Agreed here as well. This is my daily driver. No since in owning it, if I'm not gonna drive it. In 10 years, I'll want something new anyway. 400 RWHP is more than enough for me. Virginia heat, humidity and traffic suck almost all summer long. 8k is a piece of change though for so many problems I've read. Is it the kit ,or the installers?

That may be, but is this something they drive daily, or is this 500 HP beast a weekend warrior that only sees pavement when its 75 degrees, no rain, and etc etc? If you are going to critique troubleshooting/research methodologies, make sure you also compare "apples-to-apples". Though, I agree with your comment about researching 100%. The reason I say this, is because I've met many people who claim "no issues" with max HP builds, but what you don't find out till later is that this is a trailer queen, or they only average about 5,000 miles a year on the car. If it’s a daily driver through all kinds of environmental situations and they still maintain stock drivability, now that's a testimonial. If its a 1 day a week ride ,then no, I' dont think the feedback is comparable.

Ha.... I have researched just fine, and there is nobody out there running
500+ HP with no problems.

Well uhh you could find out if they're DD their Z or if its a "trailer queen" by researching... Off the top of my head I think I can think of 3 guys that DD their Z. I have a stage 2 Gtm that I DD and its over 500+hp. There's nothing wrong with daily drivin a boosted Z. If you have a good installer n a good tuner the Z will last quite a long time with double the horsepower.
The statement made earlier was simply some guy too scared or unwilling to put the money needed to boost a Z correctly. No need to try to spoil it for others with posts that a boosted Z won't last or give a lot of problems, especially in the FI section.
Just research and find out which shops have the most positive feedback and which shop has a lot of knowledge on the VQ platform and tuning. People who skip that part are the bitter ones that have problems with their Z.

6k miles so far and I still have the silly grin on my face everytime I start my car. Haven't had a single problem from day 1 except for a heavier right foot.

Btw Coon, grrrrrreat name! Lol!

Sure u did.

Coon-Azz -
My 2013 is now running flawlessly, and it is my DD. My problems related to the fact that mine was the FIRST 2013 to have a Stillen SC installed.
Cost was also higher for install and tuning because of that fact.
Stillen does run sales, especially at the end of the year.
Keep your eyes open, use an experienced installer/tuner (or install yourself) and you may well get away with 6K or a lot less. Some used kits being sold here are an option to consider as well.
Bottom line is, the car is fast enough to be fun without the kit. With this FI kit, it is much more fun. How much is that worth to you? What is your $/fun ratio?

Did you upgrade any of the plastic parts from the kit like the idler pully?

Pulley not upgraded. My installer upgraded several clamps and hoses, but not the pulley.

Thanks! Yeah, I married into a true Coonass family from LA. :tiphat:

this is good intel! 6,000 is a good run. I would assume that if you had an issue, it would have reared it head by now. :) (AND we don't want any issues) :tup:.
Also, based on my own experiences, your comment, "Just research and find out which shops have the most positive feedback and which shop has a lot of knowledge on the VQ platform and tuning." seems simple, but its (in my opinion) a major factor in the install. This will be were I focus my efforts next.

Seems to be a good decision to make. Anything plastic usually needs to go.

thanks for the feedback. Yeah, I like the concept of the Twin Turbo set up, but if you want instant on, the SC (IMO) is the way to go. The few times I've autocrossed, the SC would have been a better option than the turbo. Great advice and enjoy the new SC. (I'm so jelous). If you get a chance to post a video or two, that would be awesome. (hint hint) :tup:

It would be great to see more pictures of your install. Another thing I was thinking about changing were the hoses for the water/air cooler on the front of the intake. I would like to do some braided hoses etc. I show the car allot so some eye candy under there would be good.
When I purchased the car I pretty much conceded that I was going to put another 20K into it so I have waisted a few $$ on NA upgrades like the Motordyne intake and G3 CIA but all along I wanted to do a FI solution. In our group there are 3 guys that have TT and 2 that have SC in which one is the Stillen. Of all of them, the Stillen was the most problem free so I am going that rout. We have a great tuner in the area and he has done tons of 3.7 work both in tune and FI so I am very confident in his abilities.

Did you upgrade your clutch? I am planning on that as well along with an aluminum flywheel. May even go with the short shifter upgrade since the tranny will be dropped.

Upgrades so far -

NISMO Cat back exhaust
NISMO wheels
STILEN SC
STILLEN SETRAB Oil Cooler Kit - Race (This represents about $700 of the funds invested in the cost and install of the SC kit as it was highly recommended by Stillen due to well known overheating problems in the 370.
No new clutch.

Keep in mind the SC comes with its own CAI so if you go with the SC - your current CAI will likely end up in the used marketplace.

Just a thought re: the NISMO exhaust. It sounds great and looks good, but for the cost if I did it again I would go with the FI exhaust with the 18" resonators - IMO - looks better and sounds better.

Yea, I have the FI exhaust with HFCs and 12" resonators. CIA and Intake plenum will hit the used market. I also have to replace the clutch and CSC as well. Your running AT?

What is this AT you speak of?

Ha! just kidding, of course my Z is 6MT. Would rather ride my bike than any car with auto trans.

lol got cha.... My main question was how the new HP works with the stock clutch. The shop doing mine wants to put a new clutch and CSC in which is another $1500 installed.

Hey are you guys running the 600cc injectors that came with the stillen kit? I am and uprev told me that they were maxed out? Anybody having this issue?

I have no trouble with the clutch, but I am not racing the car.
Regarding the injectors, I am running the injectors that came with the kit. I asked my tuner about this, he seemed to feel they were more than adequate for my current warrantied Stillen tune at 395 whp

Nor am I racing the car. I've had the kit for 2.5 years now and my stock clutch is going out. I plan to replace clutch and most definitely the CSC. I'm currently experiencing slipping under heavy acceleration. I've already had the clutch fluid boil on me and turn black. had to fully drain and refill. But this is most likely due to the CSC going out....it is plastic after all!

So, if you have this kit or any FI, i'd recommend a new clutch & CSC in your near future.

Maybe I missed something, but how reliable is the stillen tune? I read through (and searched) here and read that it sucks and also read it's conservative. Does it suck because it doesn't make power or because it's not reliable or both? I'm looking into 50 state legal options for forced induction, I don't want to make ridiculous amounts power. Just a descent amount over stock and still be 50 state legal with somewhat stock reliability. Maybe it's a pipe dream, I have no idea.

Man I made 412hp and I drive it everyday to work not a single issue! When I got it tuned at uprev they told me that the 600cc injectors where not enough they were at 98% of use not a good thing. But I still drive it everyday.
