Why Turbocharge Your Wrangler?
Adding a turbocharger to a Jeep Wrangler is one of the most effective ways to unlock significant horsepower and torque gains. The stock naturally aspirated engines—especially the 3.6L Pentastar V6 and the older 3.8L V6—often leave off-road enthusiasts wanting more low-end grunt and passing power on the highway. A properly engineered turbo kit transforms the driving experience, delivering boost that helps the Wrangler climb steep grades, navigate deep sand, or simply merge onto freeways with confidence.
Beyond raw power, turbocharging can improve fuel efficiency under normal driving conditions by allowing the engine to work more efficiently. However, achieving these benefits requires careful selection of components. The turbocharger itself, wastegate, blow-off valve, intercooler, and tuning must all work together. This is where choosing a reputable brand matters—quality engineering ensures reliability, durability, and performance that lasts for years, even in harsh off-road environments.
Key Factors When Choosing a Wrangler Turbo Kit
Before diving into specific brands, understand the criteria that separate a great turbo kit from a problematic one. First, spool characteristics matter for off-road use: you want quick boost response at low RPM to crawl over boulders without constant downshifting. Second, materials must resist corrosion from mud, water, and salt. Cast stainless steel exhaust manifolds and marine-grade intercooler cores are preferable. Third, tuning support is critical—some kits come with a pre-loaded ECU flash, while others require a custom tune to match your vehicle.
Finally, consider future upgradability. A turbo system that allows you to swap compressor housings or add a larger intercooler later gives you room to grow. The brands discussed below—AFE, BorgWarner, and Turbosmart—each address these factors with their own engineering philosophies, making them top contenders for Wrangler owners.
AFE Turbo Kits for the Wrangler
AFE (Advanced Flow Engineering) has built a strong reputation in the Jeep community for its high-flow intake systems and exhausts. Their turbo kits extend that same focus on airflow and efficiency, offering bolt-on solutions for the JK and JL Wranglers. A standout product is the AFE Rebel series turbo kit, designed specifically for the 3.6L Pentastar engine.
Performance Benefits and Gains
The Rebel kit uses a GT-style journal bearing turbocharger that delivers up to 60–100 horsepower gains at the wheels, depending on boost pressure and supporting mods. AFE states torque increases of 80–120 lb-ft, significantly improving low-end response. The kit includes an aluminum intercooler with cast end tanks, mandrel-bent charge pipes, and a high-flow intake. Owners report that the power comes on smoothly, making daily driving enjoyable while still providing a strong surge when you step on it.
AFE also prioritizes ease of installation. The Rebel kit is designed with direct-fit brackets and pre-welded flanges, allowing an experienced DIY mechanic to complete the job in a weekend. Detailed instructions and a comprehensive hardware kit are included. Because the turbo is mounted low on the engine, ground clearance remains acceptable for most off-road trails—though adding a skid plate for the intercooler is recommended.
Product Lineup and Compatibility
AFE offers turbo kits for Jeep Wrangler JK (2007–2018) and JL (2018–present) models with the 3.6L engine. They also have a kit for the 3.8L JK, though availability may vary. Each kit comes with a tune via a handheld programmer, or you can opt for an ECU flash from a partner tuner. The kit retains factory fuel injectors and fuel pump at conservative boost levels, but upgrading to higher-flow injectors is possible for those seeking maximum power. AFE Power provides detailed compatibility charts on their website, making it easy to confirm fitment.
BorgWarner Turbochargers for the Wrangler
BorgWarner is a global leader in turbocharger technology, supplying OEMs worldwide. Their aftermarket turbo kits for Wranglers leverage decades of engineering expertise, focusing on durability and efficiency under extreme conditions. While BorgWarner doesn’t sell complete bolt-on kits directly to consumers for most Wrangler models, many high-end custom shops use BorgWarner EFR series turbochargers as the core of their builds.
Technology That Sets BorgWarner Apart
The EFR (Engineered For Reliability) series features a lightweight titanium-aluminide turbine wheel, reducing rotational inertia for faster spool. A stainless-steel turbine housing resists corrosion, and the dual ceramic ball bearing center housing offers low friction for enhanced response. Additionally, the integrated boost control solenoid simplifies plumbing and tuning. These features make BorgWarner EFR turbos incredibly responsive, often reaching full boost below 3,000 RPM—ideal for off-road applications.
Many Wrangler owners who demand the absolute best in reliability for rock crawling and overlanding choose custom kits built around the EFR 6758 or 7064. The boost response feels instant, allowing you to lug the engine at low RPM without lag. BorgWarner turbos also handle high boost pressures reliably, making them a favorite for those who want to push power beyond 500 horsepower with proper supporting modifications.
Where to Get a BorgWarner-Based Kit
While BorgWarner does not produce a universal Wrangler kit, trusted fabricators like Offroad Evolution and Rebel Off Road offer turnkey solutions using BorgWarner units. These kits typically include custom exhaust manifolds, downpipes, intercoolers, and tuning. Expect to pay a premium over AFE kits, but you gain access to some of the most advanced turbo technology available. Alternatively, you can source the turbocharger itself from BorgWarner’s aftermarket portal and work with a local fab shop to create a bespoke system.
Turbosmart Components for Wrangler Turbo Systems
Turbosmart is renowned for producing high-performance boost control products: wastegates, blow-off valves, boost controllers, and fuel pressure regulators. While they don’t manufacture complete Wrangler turbo kits, their components are integral to optimizing the performance and reliability of any forced induction setup. Using Turbosmart parts with an AFE or BorgWarner-based kit often yields better throttle response, precise boost control, and increased component longevity.
Boost Control Solutions
An external wastegate is the most common upgrade for Wrangler turbos, allowing precise regulation of boost pressure. Turbosmart offers the Hyper-Gate series, available in 38mm, 45mm, and 60mm sizes. The Hyper-Gate features a race-proven design with a low-friction piston seal and a vented lower spring chamber for consistent boost control even under extreme heat. For Wranglers running high boost, the Comp-Gate 40mm is another excellent option with a compact profile for tight engine bays.
Turbosmart’s e-Boost Street electronic boost controller gives the driver on-the-fly adjustment of boost levels, perfect for switching between daily driving and trail riding.
