In a hurry? Here’s our 350Z turbo kit summary

---

We’re huge fans of the Nissan 350Z here at Drifted. Its modern styling, rear-wheel drive layout, and throaty V6 make it a great choice for anyone looking to get into drifting. Also, with 350Z prices becoming ever-more reasonable, especially when compared to alternatives such as the 240SX, its popularity comes as no surprise, and neither does the fact that the 350Z made our list of ultimate cheap drift cars.

However, in stock form, the early-model 2003-06 (VQ35DE) 350s are capable of pushing out between 228 to 300 horsepower, with the “Rev-up” model producing the peak output. The later 2007-08 models utilized the VQ35HR, which increased that slightly further to 306 horsepower. While these figures are adequate for daily driving and some occasional sideways fun, chances are, you’ll soon be itching for more power. This is where things can get a bit challenging.

Since the VQ35DE is a naturally aspirated (N/A) engine, squeezing out significant extra horsepower can be costly, and the gains are unlikely to be as impressive as you’d hope. So, if you intend to transform your Z into a tire-slaying track (or street) weapon without swapping out the engine, these turbo kit options are the most convenient way of unleashing your 350Z’s full potential.

If you’re not yet fully decided on whether a turbo kit will be best for your needs, scroll to the end of this article, where we discuss other forced induction and naturally aspirated alternatives for the 350Z.

Jim Wolf Technologies Twin Turbo kit

Our comment: The JWT kit is a great starter turbo kit at a mid-level price point. It is designed to deliver around 400 horsepower in its standard form but with the potential to push up to 530 horsepower with upgraded internals and an uprated fuel system.

It has earned a solid reputation for reliability when sensibly tuned, and many consider it one of the best options for a quality, reliable turbo setup for the 350Z.

Designed specifically for both the VQ35DE and Rev-Up engines, it typically fits without requiring significant modifications. A key advantage is that it doesn’t require removing the engine or radiator for installation, and there’s no need to modify the front bumper.

Since the JWT kit is considered a high-quality option, it comes at a premium price point. However, many consider it a case of “you get what you pay for.”

Manufacturer description: “JWT originally designed this kit as a feasibility study in conjunction with Garrett and Infiniti’s product planner at the time. The kit is designed around the O.E. criteria for reliability, no boost lag, and safe but significant power levels.”

“The JWT Twin Turbo Kit has accomplished this and more over thousands of miles of reliable track and street use since it’s release. All critical airflow junctions use application specific castings to maximize flow and eliminate boost lag. Turbo outlets have isolated waste paths to improve turbine efficiency.”

“JWT has combined high efficiency Garrett GT Ball Bearing Turbos, Garrett charge cooler cores (700+hp rated) with over 300 individual parts, to create the most complete and reliable bolt on forced induction system available for Nissan and Infiniti VQ35 vehicles.”

“No other boosting solution combines the reliability, performance, and throttle responsiveness of this system.”

“This system is complete requiring no other modifications to deliver an additional 125WHP and much more with additional JWT upgrade stages.”

Rev9/GodSpeed Single Turbo kit

Our comment: If you’re seeing budget options from brands such as Rev9, GodSpeed, and Turbonetics, which are typically priced at (or around) $2,799, the chances are these are the exact same kit that has been rebranded.

Best known as the Rev9 turbo kit, this option is significantly more affordable than the premium options on the market. While there’s no denying they’re significantly cheaper than the other offerings, they aren’t known for offering the same quality, reliability, or support as the premium options.

While specific power outputs aren’t provided, you can expect to achieve around 400+ horsepower with proper tuning and supporting modifications. Rev9 recommends opting for larger injectors (600cc+), a larger fuel pump (255L), and an upgraded ECU tune to support this. Since it’s one of the few single-turbo setups for the 350Z, it will require increased spooling time, providing more turbo lag.

Although budget kits raise questions about long-term reliability, we appreciate that some of you with missile 350Zs might simply be looking to extract as much power from the VQ35 as possible. In this case, it could be a viable option, but they’re known as “China kits” for a reason – the quality just isn’t on par with the better brands in this guide.

Another downside is that budget turbo kits like Rev9 often require significant modification to fit properly. If you’re handy with welding and custom fabrication, it may be worth considering. However, the premium kits are recommended for those wanting a straightforward bolt-on solution. 

Without knowledge and experience, the initial savings on budget kits can quickly disappear in labor costs or custom work. Once these are considered, you’ll likely end up spending more for an inferior product compared to higher-quality offerings.

If you’re looking for long-term reliability and convenience, we recommend taking the sensible approach.

Manufacturer description: “Includes:

• Authentic Turbonetics 60-1 turbo charger ( good for 450hp)
• Authentic Turbonetics 38 Evolution wastegate
• Stainless steel turbo manifold set
• Stainless steel turbo downpipe
• Bolt-on intercooler kit (with intercooler 30×7.5×3)
• Type-rs blow off valve
• Oil line kit with all fittings (oil drain, oil feed)”

HKS GT Full Twin Turbo kit

UPDATED 25th March 2021: This product has now been discontinued.

Our comment: As one of the highest-regarded JDM tuners, HKS should need no introduction, and it should be no surprise that their 350Z GT full twin turbo kit is another premium option.

The JDM legends put considerable effort into developing a system that integrates seamlessly with the Z.

It is designed specifically for the VQ35DE and is a full bolt-on solution, minimizing the need for custom fabrication or extensive modifications. This simplifies the installation process and also helps maintain the car’s reliability and drivability without requiring internal engine modifications.

HKS is known for its rigorous testing and high-quality components, including impressive cast iron manifolds, providing more reliable and consistent performance. When properly installed and tuned, it provides around 400 horsepower without pushing the engine to its limits.

As always, professional installation and tuning are still highly recommended to ensure the engine operates safely and efficiently with the increased power.

Unfortunately, HKS opted to discontinue the kit, and if you can get your hands on one used, we’d still expect it to fetch a higher price tag than budget-oriented options like the Rev9 kit. The increased cost is justified by the kit’s quality, reliability, and convenience.

Big HKS fans right here.

Manufacturer description: “Twin Turbo Set Up Kit with turbochargers for high power spec Z33. Turbines can be selected from quick response GT-SS, well balanced GT2530 and high power GT-RS. Stock catalytic converters can be used with the kit.“

HKS GT-SS 350Z Twin Turbo kit

UPDATED 25th March 2021: This product has now been discontinued.

Our comment: If you’re struggling to get your hands on the discontinued GT kit above, you may also want to keep your eyes peeled for the GT-SS kit. Although not as powerful, this kit still offers a respectable performance boost with less lag than the GT kit, along with the typical HKS quality and reliability we’d expect.

Where you would expect to achieve nearer 400 HP from the more expensive kit above, the GT-SS is more suited to around the 315 HP mark.

Sure, it won’t make for the most insane build imaginable, but given the price tag, it still offers a fantastic opportunity to have a reliable, high-quality twin-turbo setup for your Z.

The GT-SS’s main positive is its quick-spooling ability, which makes for a fantastic, reasonably powered fast road setup with minimal spooling time.

Manufacturer description: “HKS Turbo Kits offer unsurpassed performance and craftsmanship from a full turbo upgrade for factory turbocharged vehicles. These kits consist of new, larger HKS designed turbos, new precision crafted exhaust manifolds, HKS poppet-style external wastegates, flanged exhaust downpipes, and all associated hardware for a complete and detailed installation.”

“HKS Full Turbo Upgrades are designed and sized to promote phenomenal top end horsepower and a good range of response throughout the RPM band for the amount of airflow. From the HKS precision crafted exhaust manifolds and downpipes to the HKS signature turbos and wastegates, each turbo kit is crafted to provide high levels of performance, quality and reliability.”

GReddy 350Z Tuner Twin Turbo kit

UPDATED 28th February 2020: This product has now been discontinued.

Our comment: GReddy, another renowned JDM tuner, showed their hands with this premium offering to rival the HKS kit. They also invested significant time and resources into creating a system that works fantastically well with the VQ35DE, but it has unfortunately also since been discontinued.

As you may have guessed, the GReddy Tuner is another comprehensive bolt-on solution, like the HKS kit, that ensures reliability and optimal response without the need for internal engine work.

The components, which include high-flow cast manifolds for optimal performance and durability, reflect GReddy’s reputation for quality. When installed and tuned correctly, the Tuner Twin Turbo kit can safely deliver around 450 horsepower.

Although they’re becoming increasingly hard to find on the used market, if you can get your hands on either this kit or the HKS (assuming they’re in good condition), we’re sure you won’t be disappointed.

If you’re tired of waiting for them to come up for sale and aren’t too bothered about the JDM appeal, then the JWT is the best off-the-shelf alternative that’s still available.

Manufacturer description: “This tuner kit features larger TD06SH-20G (900hp capable) turbos with a type 32R Front Mount Intercooler. The VQ35HR turbo kit includes all of the necessary hardware and parts to bolt right on to your car, including cast manifolds, racing downpipes, external wastegates, w/g dump pipes, a cast oil pan, and airinix intakes.”

“Because the turbos were designed to be used on lower boost stock motor applications as well as fully built race motors, it’s possible to increase the power significantly for serious performance gains. Users can enjoy flexibility when it comes to fueling options, with plenty of room to upgrade.”

APS 350Z Twin Turbo kit

Our comment: APS initially offered two widespread solutions to the 350Z turbo market. Unfortunately, both options are no longer available for purchase.

The twin-turbo kit is typically the preferred option if you can find one used and is one of the most popular big-power turbo kit offerings for the Z.

There are sometimes mixed feelings about this kit, but it mainly appears to be down to a lack of sufficient supporting mods, which has caused head gasket issues on the stock setup.

However, many owners have achieved over 100,000km with no issues, thanks to the correct tuning and supporting mods.

We recommend upgrading the head studs, purchasing a heavy-duty head gasket, and potentially purchasing forged engine internals to get the most out of this kit while maintaining reliability.

Although the single turbo kit was a popular choice, many switched to this more impressive twin-turbo setup later on.

With the correct internal engine upgrades, this kit can achieve the maximum power potential of the 350Z engine and could potentially reach the 600hp mark.

Manufacturer description: “Insane horsepower and monster torque, the APS High Output System moves the 350Z performance enthusiast exclusively into the supercar owner’s club. Best of all, the APS enhanced 350Z delivers uncompromised driveability.”

“Crisp throttle response, tidal waves of torque, silky smooth highway cruising, and excellent fuel economy all add up to an outstanding daily driver – and at your whim, mash the pedal and unleash the beast within!”

SFR 350Z Twin Turbo kit

Our comment: Speed Force Racing has one of the highest-regarded reputations in the 350Z tuning scene and is one of the few remaining kits that are still available to buy today.

The owner, Tim, is known for customizing each turbo kit to suit each owner’s individual preferences. The kit comes with three turbo options – Precision T62 Billet, Garrett GT30R, and Garrett GT35R – all of which are priced at $999.99, on top of the $7,999.98 for the kit, bringing the total to $8,999.97.

Thanks to the company’s personal touch, there’s a wide variety to choose from when finding the perfect kit. Should you have any further custom requirements, we have no doubt they’ll be happy to help.

Unlike most kits, where the claimed power figures vary wildly, SFR is proud to publish its performance figures, and it’s easy to see why it’s keen to let people know.

Not only do they make an ideal ‘stock block’ setup, which can push out 476 wheel horsepower at 10.4 PSI, but if you’re willing to go all-out with your 350Z build, they’ve got dyno-proven potential to reach 898 wheel horsepower!

Manufacturer description: “The 350Z and G35 is definitely a well rounded sports car.They have the looks that make people turn their heads.The handling of these cars is great and the power is adequate.”

“However, we felt the the performance hungry enthusiast might find the performance a bit anemic.For most people, this is not enough so we developed the Speed Force Racing twin-turbo system.Now you can have a dyno proven 476 horsepower at the wheels out of your 350Z/G35 on a completely stock motor!”

AAM Competition 350Z Twin Turbo kit

Our comment: Made in the USA, the AAM Competition 350Z twin-turbo kit is one of the ultimate picks for a complete bolt-on, OEM fitment turbo kit design for your HR-powered Z that’s still readily available on the shelf.

This kit, priced at $10,495.00, has the potential to produce up to 800 wheel horsepower alongside the usual supporting mods.

They also offer a Stage 2 alternative for $11,895.25, rated for an epic 900+ wheel horsepower!

AAM is up there with the best in the industry, and although they might not be the cheapest if money isn’t too much of an issue, this should undoubtedly be a consideration.

Manufacturer description: “The all new AAM Competition Nissan 350Z HR Twin Turbocharger System is the latest Forced Induction kit to hit the market. With innovative features, cutting edge technology, reliable operation and of course maximum power, the AAM Competition Nissan 350Z HR Twin Turbocharger System is the best forced induction system available for your Nissan 350Z HR.”

“The AAM Competition Nissan 350Z HR Twin Turbocharger System is the new standard for what you should expect for a 350Z HR Twin Turbocharger Kit. This is the most powerful, OEM style fitment turbocharger system with innovative technology and long term reliability available today. These turbocharger systems are capable of producing maximum power and with a built motor can easily achieve results in excess of 700+ wheel HORSEPOWER.”

Our winner

Our winner is the JWT Twin Turbo kit

To pick our winner from this choice of 350Z turbo kits, we looked at many criteria: ease of installation, power levels, upgrade potential, and price point.

Based on these specs, we have chosen the JWT Twin Turbo kit as our winner.

Jim Wolf Technologies Twin Turbo kit

With its high-quality components, USA-based manufacturing and support, proven track record (the kit was developed on their competition car), and price point, the JWT Twin Turbo kit makes an excellent case for itself.

The Rev9 single turbo kit might be an alternative for those on a budget, but we’d seriously consider whether the quality concerns are going to suit your needs. It’s also worth remembering that the single turbo suffers from increased lag.

Although the two Japanese kits from HKS and GReddy are great options, finding them is becoming increasingly hard, and replacement parts are even harder to come by.

SFR and AAM have delivered in recent years, providing fantastic kits for those looking for alternatives to the JWT kit. These kits offer much more customization and incredible power potential of over 900 wheel horsepower if you’re willing to spend big bucks on your Z!

Additional 350Z Turbocharging Considerations

Although they look fantastic, Nissan’s 350Z is undeniably a heavy car. With the stock engine, it can feel a little low on power when trying to keep up with other performance cars. To put things in perspective, the 350Z is generally 400-800 lbs (180-360 kg) heavier than the Nissan 240SX or around 800-1,200 lbs (360-540 kg) more than the Mazda Miata, depending on the specific model.

Thankfully, the 350Z engines can produce far more power than Nissan provided from the factory. They’re strong enough to handle 400-wheel horsepower from forced induction in stock form, and turbo kits provide the most convenient upgrade for unlocking this power potential.

However, before considering a turbo upgrade, you’ll need to consider the bare minimum supporting breathing mods, such as an exhaust system, Y-pipes, test pipes, headers, an intake plenum spacer, and a Cold Air Intake (CAI). Depending on your power goals, you’ll likely need to consider purchasing an uprated clutch while you’re there.

Another consideration for upgrading to a turbocharged setup is cooling, with bolt-on parts such as a front-mount intercooler and an uprated radiator being essential. While not essential, an oil cooler is recommended to help maintain stable oil temperatures.

Remember the suspension and brakes, too. We highly recommend a coilover upgrade. Although it’s easy to get carried away with chasing down colossal power gains, handling is essential to getting the most out of your setup.

If you want to go even further, check out our 350Z mods guide, where we explain everything you need to know about upgrading your Z.

For those who intend to go beyond the stock-engine safety bracket of 400-wheel horsepower, you’ll need to consider internal upgrades to your engine rather than regretting it later.

Uprated head gasket upgrades are highly recommended, but additional internal upgrades, such as forged pistons, rods, and cams, are also wise choices for optimal reliability.

Upgrading the fuel injectors and fuel pump to ensure adequate fuel delivery for the increased power demands will also be essential. High-flow fuel injectors and uprated fuel pumps are the go-to upgrades.

Depending on the power you intend from your build, you may also want to consider further clutch and transmission upgrades.

Lastly, having a highly-regarded tuner install the kit correctly will be essential for optimal power delivery and long-term reliability. If you carry out any significant upgrades after this, we recommend re-visiting to ensure it’s still running optimally.

350Z Forced Induction Alternatives

Given the popularity of tuning the Z33 chassis, there are also plenty of 350Z supercharger kits available.

If you’re not sure whether a turbo or supercharger upgrade will be best for your needs, make sure you check out our detailed turbocharger vs. supercharger guide, where we explain everything you need to know about how they compare.

While forced induction is undoubtedly the most convenient way of extracting power from the VQ engine, if you’re looking to stick with the N/A setup as Nissan intended, you’ll be surprised at what it’s truly capable of. This 537-horsepower N/A build from the same JWT team that makes the recommended turbo kits in this guide shows off the true expertise of these Z-chassis tuning legends.
