1. Greddy T78 Turbo Kit for VQ35DE: Top Overall Pick

🛒  Check Price on Amazon →

The Greddy T78 turbo kit is widely regarded as the benchmark for VQ35DE turbo conversions. It includes everything needed to get boost flowing, from the manifolds and downpipe to the intercooler and oil feed lines. The engineering is purpose-built for the 350Z and G35, so fitment is far cleaner than universal kit alternatives. For enthusiasts targeting 500 whp or more on a built motor, this kit checks every box.

The main trade-off is the turbo size itself. The T78 is a large snail, and below 4000 rpm throttle response is noticeably soft. Street drivers who spend most of their time in low rev ranges may find this frustrating. This is firmly a premium tier investment and assumes you have budget remaining for a proper tune, supporting fuel system, and ideally a built bottom end.

• Bolt-on fitment designed specifically for the 350Z and G35 chassis
• Capable of supporting 500 to 600 whp with proper supporting mods
• Comes with Greddy's detailed installation instructions and quality fittings

Pros: Excellent build quality with well-machined flanges and tight-fitting piping; Strong community support and wide tuner familiarity with this kit
Cons: Large T78 turbo produces noticeable lag below 4000 rpm, making city driving less responsive

2. Turbonetics Street Kit for Nissan VQ35DE: Best Street Drivability

🛒  Check Price on Amazon →

Turbonetics built this kit specifically around street usability. The smaller turbine housing allows boost to build earlier in the rev range, so you get a meaningful power increase without the flat low-end that plagues larger setups. For a 350Z that doubles as a daily driver, that trade-off in peak power is usually worth the much improved driveability. Installation is straightforward compared to some universal alternatives.

Where this kit falls short is ceiling. Serious power builders chasing 500 whp or beyond will outgrow this kit quickly, making it a poor choice if your goals escalate over time. It is best suited to enthusiasts who want a reliable mid-range boost bump and have no plans to push past 380 to 400 whp. Budget to tune accordingly, as no kit should be run without a proper calibration.

• Designed for street use with a smaller turbine housing that spools by 3200 rpm
• Includes oil and coolant lines, exhaust manifold, and intercooler piping
• Compatible with both HR and DE variants of the VQ35 with minor modification

Pros: Noticeably faster spool than large-format kits, keeping the power band usable on the street; Turbonetics has decades of experience in American turbo manufacturing
Cons: Peak power ceiling is lower than big turbo alternatives, topping out around 400 whp on a stock block

3. ISR Performance Turbo Kit VQ35DE 350Z: Best Value Complete Kit

🛒  Check Price on Amazon →

ISR Performance has carved out a niche serving enthusiasts who want a legitimate turbo setup without a premium brand price tag. This kit covers the essentials, including a T3 T4 turbo, a front mount intercooler, all piping, and an external wastegate. For someone stepping into turbocharged territory for the first time on a budget, it provides a workable foundation that experienced fabricators and tuners can build on.

The compromise is build consistency. Online forum threads document cases where buyers received kits needing minor welding corrections or gasket surface cleanup before install. This is not universal, but it is common enough that you should budget time for inspection and possibly a small amount of fabrication work. That said, those who get a good unit and tune it properly report solid results well into the mid-range power bracket.

• Full kit includes T3 T4 turbo, front mount intercooler, and external wastegate
• Designed for 350Z and G35 with chassis-specific piping bends
• Budget-friendly entry point into the turbo world for VQ35DE owners

Pros: One of the most complete kits available at a budget price point; External wastegate gives solid boost control without extra cost
Cons: Weld quality on flanges can be inconsistent and some owners report needing minor fitment corrections

4. Forced Performance FP Green Turbo Kit VQ35: Premium Power Builder

🛒  Check Price on Amazon →

Forced Performance is well-respected in the Subaru community and their VQ35 kit carries the same engineering discipline. The FP Green turbocharger is a Garrett-based unit with a strong reputation for broad power delivery, avoiding the spiky powerband that plagues some competitors. The tubular equal-length manifold is a genuine performance advantage over cheaper log-style designs and contributes to a more linear boost curve.

The honest limitation is the stock intercooler size bundled with the base kit. Once you push past 450 whp, the intercooler becomes a thermal bottleneck and heat soak becomes a real concern on back-to-back pulls. Buyers planning aggressive power builds should budget for a larger intercooler core upfront rather than retrofitting later. Overall this is a premium tier kit that rewards proper supporting modifications.

• FP Green turbo is a Garrett-based unit known for broad power band and strong top end
• Exhaust manifold is tubular and equal-length for improved spool characteristics
• Fits HR and DE engine variants with appropriate adapters

Pros: Excellent turbo quality with strong top-end power and a usable mid-range; Equal-length manifold improves spool response compared to log-style designs
Cons: Intercooler sizing in the base kit is marginal for those pushing beyond 450 whp and often requires an upgrade

5. Apex Power Tuning Single Turbo Kit VQ35DE: Budget Entry Pick

🛒  Check Price on Amazon →

The Apex Power Tuning kit is best understood as a parts bundle rather than a true bolt-on solution. The turbo core is functional and capable of supporting mild power builds in the 280 to 320 whp range, which is a meaningful gain over stock. For someone with fabrication skills or access to a skilled shop who wants to minimize parts cost, this kit provides the core components at the lowest price on this list.

The weakness is the fitment. Piping is generic and requires hands-on adaptation, and several buyers report spending additional hours in the garage resolving alignment issues. For a first-time builder without fabrication experience, this can turn a weekend project into a month-long frustration. This is a budget tier pick suited to skilled DIY builders, not plug-and-play buyers.

• Affordable entry-level kit for those on a strict budget
• Includes basic front mount intercooler and oil feed hardware
• Compatible with 350Z with custom downpipe work

Pros: Lowest price point of any complete kit on this list, making it accessible for tight budgets; Turbo core itself is serviceable for mild 300 whp builds
Cons: Piping fitment is generic and requires custom fabrication work to mount cleanly on the 350Z

6. Rev9 Bolt On Turbo Kit VQ35DE 350Z Infiniti G35: Best Fitment for G35 Owners

🛒  Check Price on Amazon →

Rev9 is a value-oriented brand that focuses on chassis-specific fitment, and this kit delivers reasonably well on that promise. G35 owners in particular benefit from the explicit dual-fitment design, as many competing kits require additional adapter work to fit the Infiniti platform. The cast iron manifold is a durability plus and resists the cracking that sometimes plagues thin-wall steel units under repeated heat cycling.

The weight penalty of a cast iron manifold is the real downside for performance-focused builds. On a track car where every kilogram matters, the added weight in a mid-ship position is worth considering. For a street-driven G35 that sees occasional canyon runs, it is a non-issue. This kit lands squarely in mid-range territory for price and performance and represents a solid middle-ground choice for dual-platform VQ35DE owners.

• Explicitly designed for both the 350Z coupe and Infiniti G35 sedan and coupe
• Includes cast iron exhaust manifold, intercooler, BOV, and wastegate
• Targets 350 to 450 whp range on a stock or mildly built VQ35DE

Pros: Better than average fitment for G35 owners compared to kits designed only around the 350Z; Cast iron manifold holds heat well and resists cracking better than thin steel alternatives
Cons: Cast iron manifold adds significant weight compared to tubular steel options, which matters on a track build

Frequently Asked Questions

How much horsepower can I expect from a turbo kit on a stock VQ35DE?

On a stock bottom-end VQ35DE, most single turbo kits running 7 to 9 psi of boost produce between 350 and 450 wheel horsepower with a proper tune. Pushing beyond that on stock internals carries real risk of spun bearings or cracked pistons. If your goal is 500 whp or more, budget for a built motor with forged internals before selecting a large turbo kit.

Do I need a tune after installing a turbo kit on my 350Z or G35?

Yes, absolutely. Running a turbo kit without a proper engine management tune is one of the fastest ways to destroy a VQ35DE. The stock ECU cannot accommodate the increased airflow, altered fueling demands, and boost pressure. A standalone ECU or piggyback tune by a qualified tuner is not optional. Factor tuning cost into your total budget before purchasing any kit.

Is the VQ35DE or the VQ35HR better suited for a turbo kit?

Both engines can be turbocharged, but most dedicated kits are designed around the DE variant. The HR has a higher compression ratio (11.0:1 vs 10.3:1 on the DE), which increases detonation risk under boost and typically requires lower boost pressures or higher octane fuel. The DE is generally considered more turbo-friendly for aggressive builds, while the HR can still be turbocharged safely with appropriate supporting modifications and conservative tuning.

What supporting modifications do I need alongside a turbo kit?

At minimum you will need an upgraded fuel system including larger injectors and a higher-flow fuel pump, a standalone or piggyback ECU tune, and quality engine oil with more frequent change intervals. Most builds also benefit from an upgraded clutch or transmission service. For higher power targets, forged internals, upgraded cooling, and a larger intercooler become necessary. Do not treat the turbo kit alone as the finish line.

Will a turbo kit void my car warranty?

In most cases, yes. Adding a turbo kit to your VQ35DE will void powertrain warranty coverage on any components affected by the modification, including the engine and transmission. If your vehicle is still under factory warranty, that is an important consideration. For older 350Z and G35 models that are well out of warranty, this is a non-issue, and most buyers in this space are modifying older vehicles where the factory warranty expired years ago.

Our Verdict

After researching and comparing the field, the Greddy T78 Turbo Kit stands out as the top pick for enthusiasts who are serious about high power builds and want proven fitment with strong community support. For buyers seeking better street manners and faster spool without sacrificing reliability, the Turbonetics Street Kit is the runner-up and a smarter choice for daily-driven 350Z and G35 builds. Whichever kit you choose, invest in a quality tune and appropriate supporting modifications before turning a boost dial.
