Yup gonna need a bigger blower which is a problem because they dont fit with the stillen brackets. Good luck though you have a step uphill battle to fight because that kit has been dissected and rebuilt for so long here in the states its hard to see where you are going to find more power without throwing out half the kit. Dont forget about giving 928motorsports out of wisconsin a call for their billet wheel and high speed bearing upgrades if you are going to stick with the stillen head unit. Ported housing wouldnt be a bad idea, as well as doing something different with intake filter and coupler and not using the stillen manifold, intercooler, or piping, and DEFINITLEY not using their tune.

Now that i reread that, yup youre going to end up throwing most of it out. Thats why people buy the gtm kits i guess

Hehe trust me it's not the head unit that's the problem it's the kits configuration
That small water to air cooler is not going to get it
You will be just blowing hot air into the motor and your computer will pull timing

You would have to remake that kit to get big power out of it

Larger cooling system maybe change over to fmic
Fab. The intake pipping and move the maf sensors

The v3 is a good head unit but like anything it's only as strong as it's weakest link

I would have saved my sell tons of money if I did alittle more research before buying that kit

Guys, no one has anything positive to say about the stillen setup?

thanks :)

It's cheaper than the GTM? If you live in CA it's legal to drive with it...?

Besides that... No one... No reason to say anything positive... It's a really expensive way to make it faster... Momentarily... Nitrous is much cheaper and the $4k+ you'll save going that route can be used on Nitrous fill ups.

God knows where you're getting nitrous in Israel, but pay off a dentist or something

So why do people buy it? Besides carb reasons.

thanks :)

BESIDES CARB?
Great advertisement, people don't know any better, people are enticed that they can buy an engine warranty.

I tell you that I don't know anyone personally who is TRULY satisfied with it. I know a local guy who has his car fully Stillen kitted out (whole body kit), had the kit installed AT Stillen, and all he says is that after he guns it once or twice oil temp skyrockets and his car is slower than before

Unfortunately, this. The only reason someone who isn't crippled by California emissions laws buys a Stillen kit is lack of research.

The Stillen SC kit looks very good on their site, the description is well written and the numbers are very tempting. Someone who hasn't done his forum time and read the various reviews would never know what the real deal is.

Google "370Z Supercharger" and see what comes up :)

I love my Stillen kit and it's a blast to drive but I was never trying to hit a number. I wanted to give the car more power and I am thrilled with it now that the Stillen tune is off of it. I don't think you will like the kit if your goal is 550whp because the kit isn't designed to get you there. I know others have been told different but Stillen told me 500 hp at the motor not the wheels.

Here we go again , I tried this too we all remember?? I made 457 WHP and 330 wtrq at 11psi. With a bunch of upgrades(stg 2 kit) ! Impeller, fuel, and custom frontmount heat exchanger , and MAF's , if you make more than that I'll be very supprised . As it was said already the headers Stillen has said won't help, an the blocks limit is around 13 PSI ( was told by my tuner for a SC) so I wouldn't suggest going that high on the motor or trans .
Oh did I mention my motor BOOM'd also. :(

Actually I think that was the ultimate form of sarcasm I just never realized it! I'm with Trips on this one OP! Go ahead drop all that cash man! I can't wait to see the power u put down!!!

I want you guys to realize that things here are very expensive (off the charts) because of customs tax. My car cost me 105,000 dollars. Just to get the standard Stillen/GTM kit here would be around 13,000 dollars. My friend who posted here 530 or so WHP paid these amounts for his kit (GTM). The short is that someone bought the Stillen kit and decided not to install it. He is willing to sell it to me for about 5500 dollars. That's cheap for here; very cheap. I know that the kit won't make the same HP as the GTM; although, I am not really sure why (not technical at all.) I just know how to drive. What would you guys do? Either no kit (can't afford GTM here), or get the Stillen?
I think I was misunderstood in my original post. My intentions now are to install the kit as is and with a proper tune get the max HP out of it. You must realize that because of the prices here car upgrades are a very grey area. Almost everyone in the states knows the basics such as how to change the oil or small repairs. Here it's the exact opposite. As to the guy that said that I didn't do research; well I did and my pockets aren't deep enough for the GTM (13000 dollars.) What I would like to know from the forum members is what realistic HP I'll be gaining with a custom tune and whether the Stillen kit is a good and reliable kit for what it is. If anyone says anything different then maybe I'll say "screw the kit" and I'll continue stock. The most important thing for me is reliability; meaning a daily driver with almost no hiccups.
Thanks

Looking at those costs, it all makes a lot more sense.

You can make it reliable. Get a custom tune, and go overboard cooling the oil, water and intake charge. Just don't expect massive power. It'll still be a lot more power than stock.

To give you some answers on what the kit can do check out this thread: http://www.the370z.com/forced-induct...tml#post614396

Depending on a lot of factors you should be able to get 400whp out of the system, some of the 440whp+ on the list are people who took the stillen kit and modified it to get any extra power out of the kit.
