Steve Millen and has talented team know a thing or two about turning Nissan products into Stillen rockets. The latest project to emerge from the tuning company's garage is the supercharged 370Z you see above. The bolt-on kit is legal in all 50 states thanks to the thumbs-up from the California Air Resources Board (CARB), and it comes with a three-year, 36,000-mile warranty. You won't care about emissions when you're behind the wheel, though – the supercharger kit means this hotter Z now produces over 500 horsepower.

If you own a vehicle with the VQ37 engine, such as the 370Z or Infiniti G37, you owe it to yourself and your machine to turn it into a sports car capable of embarrassing BMW M3 owners. The heart of the Stillen kit is comprised of a Vortech V-3 supercharger, which is fed via a cast-aluminum intake manifold, has a self-contained oiling system and runs on a V-belt design.

Stillen worked hard to make sure this unit fit under the stock hood, unlike the setup created for the Nissan 350Z. This time around there is no need for an ugly hood hump blocking your line of sight. Click past the jump to see the supercharged Stillen 370Z in action.

STILLEN Obtains 50-State Legal Status for Nissan 370Z / Infiniti G37 Supercharger System

For over 25 years STILLEN has been recognized as a leader in Nissan/Infiniti tuning. With a history of setting "first time" milestones in the aftermarket for these great vehicles, STILLEN has established themselves as the company to follow when it comes to Nissan and Infiniti product development. STILLEN was the first company to develop the HICAS eliminator system for the 300ZX Z32 platform. When the Z33 350Z was introduced, STILLEN was once again the leader with the first forced induction solution, as well as the first to offer CARB legality, and AGAIN the first with a 3 year/36,000 mile engine warranty. Well, STILLEN has done it again as Team STILLEN is proud to announce the CARB approval of the Nissan 370Z (Z34) G37 Supercharger Kit.

STILLEN has not only been the first company to achieve CARB legality of a forced induction solution on the VQ37, we have also been the first company to achieve such an accomplishment while tuning through Nissan's sophisticated ECU with larger injectors. This is a major accomplishment for Team STILLEN and one that will join the many other first time landmarks STILLEN has achieved in the Nissan/Infiniti tuning world.

CARB (California Air Resources Board) is the division of the California state government that controls all aspects of air quality and standards. With standards getting stricter it is getting more and more difficult to achieve CARB legality. CARB is recognized as the toughest emissions control in the country and is therefore recognized in all 50 states as an emissions standard for all performance parts. If a performance part achieves CARB legality, it is recognized as 50-state legal.

The power the STILLEN Supercharger system delivers is dramatic, taking the factory 3.7L V6 from 332hp to over 500hp! System is designed to work with both automatic and 6-speed vehicles, including convertible and AWD models.

The STILLEN VQ37 Supercharger features a new cast aluminum intake manifold designed specifically for this system, complete air-to-water intercooler system, and boost is derived from a Vortech V-3 Supercharger unit. The V-3 features a quiet V-belt design, and a self-contained oiling system for easy maintenance.

In the past year STILLEN has shipped supercharger systems around the world. Fantastic reviews and reports are coming in from:

Australia
New Zealand
Singapore
Russia
Thailand
Korea
Canada
Switzerland
Taiwan
France
United Arab Emirates
China
Hong Kong
United Kingdom

Not to mention all of the kits that have been installed with great success across the United States at Nissan/Infiniti dealerships and performance shops. This is a bolt-on system, capable of being installed by any qualified ASE-certified automotive performance shop, or at hundreds of Nissan and Infiniti dealerships across the country, or right here at STILLEN at our in-house install facility.

Once again, STILLEN has successfully accomplished all of its goals with another great forced induction solution for the Nissan/Infiniti vehicles.

Features Include:

• Vortech V-3 Centrifugal Supercharger Unit
• STILLEN purpose designed cast aluminum intake manifold with long runners for increased torque
• Installs under the stock hood - No modifications needed
• Complete system includes pre-assembled Vortech V-3 supercharger assembly, air intake with polished air charge pipe and genuine K&N intake filters, fuel injectors, air-to-water intercooler, UpRev ECU Tuning cable/software and detailed installation instructions.
• Optional 3-year/36,000 mile powertrain warranty
• Made in the USA
• 50-State Emissions Legal (E.O. Number D-436-17)

      Pretty insane, I was just thinking how that motor would do in a G37 sedan or FX37, total sleeper.

      I don't know if my wife would appreciate such efforts on her G37. The car would probably end up driven through the back of the garage.

      so just slap on a blower and make no modifications to the bottom end that has compression ratios and rods designed for a N/A setup? nice.

        Basically, stock Z internals have thus far held up to 500-550whp and over 400tq on stock rods and pistons.

          I have tracked my G-37 S coupe without the oil problems mentioned. Do any of you guys actually own a G-37?

      As an M3 owner I am more amused than embarrassed when people driving cars like this try to impress me.

      I've done business with Steve Millen before. He's a real stand up guy, and he really knows Nissans well. I'd much rather see his projects on AB than that low-life crook John Hennessy's.

      More power in a chassis that allready couldn't handle what the factory gave it.

        Evidence? The chassis is great, the handling numbers are superb for the price. The brakes and cooling suck.

      The good thing is that its CARB approved. The bad...this kit in most cases will not live up to the advertised numbers and I'm pretty sure the CARB kit does not give 500 at crank. If you aren't concerned about CARB approval, look up GTM a much better and reliable kit. To the M3 owners, you guys come running after my Z and I while we're just driving along as normal. I love it when I leave you guys with a shock look on your face and this while still N/A. You guys paid for a watered down M3 that is an embarressment to the true M mindset. You're just a padded GT car, SMG guys don't get me started you lazy drivers. The Z is a driver's car, leave your creature comforts at home and put your foot down.

        Lets not get all crazy here. I test drove a 370Z and it was pretty soft with not a ton of steering feel and a coarse engine that did not feel eager to rev. I was unimpressed except for the price tag.

        @BladeZ34
        i agree with you 99%, except that your Z has downshift rev matching. i don't see how that's any different than a SMG.

          Rev match can be deactivated. And the SMG only has 2 pedals.

        Actually, the car used in the CARB testing is owned by a local Los Angeles resident and has multiple dynos at above 500 crank HP. Before you jump on the GTM band wagon you might want to check out the Yelp reviews.
          BladeZ34
          • 3 Years Ago
          @Chuck Jr
          Wow I actually had not seen those reviews previously. I haven't dealt with GTM on a big project like this, I've purchased an oil cooler from them as well as test pipes and the transactions have gone smooth, Sam even assured me and explained to me how they addressed the oil cooler lines issue from when it first came out. I've inquired as to the reviews on yelp.com. However, numbers don't lie, the Stillen kit has less room for growth and frankly if I don't need CARB approval this is not the kit I would get.

      Yea, I love when articles like this say "Embarrass M3 owners" or "Embarrass Ferrari 458 owners"....lol. I forgot people buy cars for the most horsepower to go street racing, not because they just love a certain car...

        There are always people who buy cars based on numbers and specs, simply because they don't know any better. Just take a look at the comment section of the Maserati GranTurismo review. Someone doesn't understand why anyone would buy a Maserati when a Hyundai coupe is just as fast. At the end of the day though, 370Z owners and the like are looking to race others and boost their self-esteem, while M3 drivers are enjoying the knowledge that they are happy with their purchasing decision.
      me
      • 3 Years Ago
      I hope they have addressed cooling. The stock (even Nismo) 370Z goes into limp mode and reaches super high temps if driven hard / on track. It should have come with an oil cooler stock.
        PatrickH

        Don't forget the brakes overheat too, though I suppose they can't when in limp home mode, lol.
