Look at it this way, do you learn to ride a Motorcycle on a 1000cc/240 HP Super Bike. For enthusiasts, the kit is fine. Just a few recommendations to make it more reliable based off guys input that have ran the kit for a wile.

$170.00 25mm dual port BOV: JSC Speed
$38.95 idler pulley 4gr116-300 3inch from Vortex

The stock bands that hold the boost side on the manifold work fine but more reliable to have these on the pressure side. Good luck with what ever you choose to do!!!

Thanks, glad to see there are more people out there in the same boat as me. I personally like the GTM supercharger kit the most because from what research I've done it's a cleaner install and doesn't require you to mangle you car as much the stillen kit does. But, as with anything things change and I could be wrong. Problem is even though I don't live in California and probably wont anytime soon I still want something smog/carb approved. Maybe it's overkill, but it would give me piece of mind when getting pulled over and/or going through emission testing.

[QUOTE=elperuano;2141180]It's amazing that the inferior Stillen kit still gets this much play.

The main reason everyone goes for this kit is because with the Stillen SC and Stillen tune it's supposedly still keeps "warranty". For everyone that went this route they quickly realized the cost wasn't worth what the Stillen SC provided. The Stillen tune is complete garbage. You can almost make the same with the most mods people go with anyway i.e. exhaust intake tp/HFC and an Osiris tune.
Once people realized Stillen tune was garbage, to save face they threw the warranty out the window and went with a custom tune. Even then the gains for what ur paying is minimal....

There seems to be some venom against Stillen out there. Not sure why but…
My experience was not seamless, but the above hardly reflects what actually happened.
I am no expert. I wanted SC because of the faster power response. I have had several turbo cars and could always feel the turbo lag. Even in my brothers 2011 335 with a stock TT set up the lag is apparent.
My research showed Stillen to be the best option for a supercharger. I was looking for HP gains well beyond what non-FI options can provide and from what I can tell, the statement “…You can almost make the same with the most mods people go with anyway i.e. exhaust intake tp/HFC and an Osiris tune…” simply isn’t true. The best by far I have seen any one report without FI is roughly 340whp and that was with high flow cats – definitely not CARB legal and generally marketed as an off road option only.
The GTM kit lists for $8726 for the satin kit (without an oil cooler). Their web site states “…This includes installation with before and after dyno testing. Expected results for this with tuning session are 360-400 rwhp….”
In order for them to include installation in the price one would presumably have to go to them for the install. Not an option for me.
Stillen’s kit lists at $6300 for the Satin kit and estimates 12 hours for install. The oil cooler was $600 with tax and shipping. My install costs including the 25 row oil cooler and all the extra work (due to previously described issues) was $1900. So installed with oil cooler (not included in GTM kit) was $8800. Realistically $7800 without the oil cooler.
That is over $900 less than the GTM and I dyno’d at 394 whp on the Stillen tune with snow tires. I am told by my tuner to expect roughly 405whp with my NISMO wheels and summer tires. So on a cost/hp ratio, I believe I did better than with the GTM kit.

Might not be every Stillen owner but the MAJORITY yes.
Money to power it just doesn't make sense. Ur at 394 n the highest you saw NA was 340. Compare what that NA paid to what u paid for 50 more hp.
Another thing you said was SC is instant power? At 3.6-3.7k rpm I'm at full boost. I'm barely under that rpm every shift if running the car hard so it's almost instant boost every shift after.
There are much better SC kits out there in my opinion. As always just research before pulling trigger. I like doing things right the first time to save money in my pocket and wear on my car. Too many times I've read a Stillen owner upgrading this and that, adding this and that and every change requires another dyno tuning session which is more money and wear on motor.

I think he's referring to the lag between pressing the throttle and the time the turbo needs to produce positive pressure. There's always going to be lag in a turbo setup. Your boost threshold may be 3600 rpm, but there's a delay between pressing the throttle and the time the turbo spins up. On a WOT run, it's less noticable than transitional on/off throttle situations. A turbo setup will never have the same throttle response as a SC since you're driving the SC directly off the crank pulley. It's a trade-off. SC's are going to have better throttle response while making full boost closer to redline and producing less torque. Turbos just have more steps in the process to making boost, and it shows up as lag. I'm not going to touch the Stillen vs GTM SC issue.

Quote for truth. All turbo setups have on/off/on throttle lag.

Yep. Unless you're running some sort of anti-lag setup, in which case you have either bigger balls than I do, or an unlimited turbo budget.

elperuano · 02-01-2013, 12:18 PM

It's barely noticeable IMHO. It takes as long as it takes my gas pedal to hit the floor. On WOT I don't even feel it in between shifts. When cruising and I wanna make the BOV go off yea I can feel it but I'm cruising not running hard. I think you guys r giving the "lag" way too much credit. I'll still take the half second delay over that particular SC anyday.

You're right, it's barely there. But it's still there and some people prefer a SC for a snappier throttle and instant boost. There's a lot to be said about instant, linear response. I thought really hard about a SC, but I know that I'd end up wanting more later down the line. I didn't want to paint myself into a corner. The OP sounds like he's perfectly happy with his setup. That's great. If he ends up needing more power later, he can swap pullies, injectors and re-tune. It's not as easy as turning the knob on my boost controller, but it's not that hard.

Very well said. The only real point in reading these forums is that there are so many opinions. Those opinions are based on many different circumstances and attitudes. There are posters from the age of 15 to 50, and those that will never be happy and those that will never have enough power. And of course those who think that if you don't do it like they did it then it is wrong. The great thing is that you can read through all of that and pretty quickly determine what is BS and what you can actually use. The bottom line is your car is unique to you, and your wants are not what others may be wanting so don't get caught up in the negativity. Since this is a "Stillen" thread, I will proudly say that I just ordered my Stillen SC and it's on the way. I am completely happy with my decision and have done enough research to satisfy me. My expectations are in line with what I know about it and I plan on being okay with it. If its not, then I will change it.
Thank you for all of the info that I have absorbed from this and other threads and to all of you who just state your experiences and not just come in here to bash a product that may not have worked out for you.

hmm... first off I have never seen anyone other than one report with anywhere near 340 whp non-FI.
Additionally high flow cats and test pipes are for track use - so that is off the table. So subtract roughly 10-20 whp.

In real life - If you look at claimed numbers for the usual suspect non-FI mods you get for cost/HP gains -
Exhaust – roughly 10-20 whp for $1270 plus install
CAI – 12-20 whp, $530 plus install
Headers – maybe 15 whp – 550 plus install
Our car makes 270whp unmodified, so with all of the above you get maybe 45 whp – or 315 total for around $2400 with plus tax and installation, arguably 4K said and done, or $90/whp.

Stillen SC at $7800 for 125 whp is $62/whp – I like that ratio better.

Really I don't see any comparison in power. FI is pricey and if you look at my recent thread Stillen SC long term reports you will see reports so far of close to 500whp with minimal problems.

I forgot about the "carb or smog" thingy. Ur right about that, but any Stillen SC making anywhere near 500hp is not using the Stillen tune therefore the "warranty" gets voided.

SS_Firehawk · 02-01-2013, 03:06 PM

I spent $5500+ install for about 50whp. Pretty sure a SC will outperform that dollar per hp quite easily. Keep in mind, most people with FI spent money on supporting mods also. The kit may have cost $6k, but they also may have purchased a CBE, HFC or TP's. Most also do their own custom tuning which is another expense. That 6k all of a sudden looks like 9-10k after it's all said and done.
