Photographers: The Manufacturer

We've spent countless hours driving 4.0L-equipped Jeeps, chiefly in Wrangler TJs, Cherokee XJs, and a Grand Cherokee WJ. They've all been great vehicles with one thing in common—a somewhat anemic engine that waned whenever you needed additional horsepower and torque the most. Weighing the popularity of the 4.0L-equipped Wrangler TJ, the team at Banks Power decided to address this issue head-on with the introduction of its 4.0L Sidewinder Turbo system.

The goal of the Banks Power 4.0L Sidewinder Turbo system was to improve low- and mid-range torque for increased power on the trail and improved drivability on the pavement. Banks accomplished this goal. The Turbo delivers nearly 50 percent more horsepower than stock and just over 50 percent more torque. In fact, torque output with the turbo at 1,600 rpm is greater than the peak torque in stock condition. This aggressive torque profile is ideal for rock-crawling and trail-running scenarios.

We spent a few days at the Banks Power engineering facility in Azusa, California, to familiarize ourselves with the 4.0L Sidewinder Turbo system. It's a high-end system that will not disappoint. With huge horsepower and torque increases, it effectively transitions the venerable-but-lacking 4.0L engine into V-8 or diesel territory. Check out the photos and captions for all the details.

Is it just another aftermarket air intake system? Not this time. Banks Power recently unveiled its Sidewinder Turbo kit for 2005-to-2006 Jeep Wranglers equipped with the 4.0L I-6 engine. Horsepower and torque improvements are huge and greatly benefit street and trail-driving situations. Model year coverage will be expanded to include 1999.5-to-2004 Wranglers, as well. The hardware will be essentially identical to the current system, with a different electronic tuning to cooperate with the older-style ECU. Is it just another aftermarket air intake system?

The Banks Power 4.0L Sidewinder Turbo kit includes a turbocharger with integrated wastegate/blow-off valve, a cast-iron turbo mount with alternator relocation, Bosch 35 lb/hr fuel injectors, stainless-steel turbine inlet/outlet pipes, a boost tube with provisions for water injection nozzles, a two-bar MAP sensor with a billet throttle body spacer mount, a handheld flash programmer, a Turbo-specific Ram-Air system with a through-hood Super Scoop, a boost gauge, and all necessary hoses, fittings, and hardware. Installation is relatively simple, and the entire project can be completed in one day.

The turbocharger features an integrated wastegate and blow-off valve. The latter is in place to relieve pressure during drop throttle, allowing the turbo to stay spooled up and eliminate turbo lag. The standard turbo system operates at 6-psi boost. By adding an intercooler (for on-road use) and/or water/methanol injection (for off-road use), boost can be increased to approximately 10 psi to create power improvements of 20 percent to 30 percent over the base turbo system.

The cast-iron turbo mount and alternator relocation bracket is a great item that could even be used as a standalone part to relocate the alternator and incorporate an air compressor or other beltdriven accessory. The bracket secures to the engine block and head in multiple locations using provided hardware.

Stroker kits that range in displacement from 4.5L to 5.0L will offer power/torque increases of 12 to 25 percent, compared to the 50 percent improvement with the Sidewinder Turbo system. Taking all costs into account, the turbo offers a better horsepower-per-dollar value. A turbo system also functions as an altitude compensation device in that it will still give increased density in the cylinder—greater than atmospheric pressure—by providing boosted air when ambient conditions are diminished. A stroker engine cannot offer this benefit as it only deals with barometric pressure.

The Ram-Air intake system is unique to the application and is available with an optional through-the-hood Super Scoop. Both versions of the system are designed with a slightly higher-than-stock entry point, leaving no compromise for water fording. The Super Scoop is modeled after the international version of the Jeep Liberty. The Ram-Air intake system is unique to the application and is available with an optional through-the-hood Super Scoop.

Included with the Sidewinder Turbo system is the Banks AutoMind programmer, which is pre-loaded with a calibration specifically designed for the turbo system. The AutoMind can also display a host of critical engine functions and provides “service technician” diagnostic capabilities with its ability to scan and clear vehicle trouble codes. You can also adjust or remove the top-speed limiter, adjust cooling fan activation temperature, and calibrate the speedometer for different tire size, axle gear ratio, and transfer case ratio.

Banks recommends use of its Banks iQ to further enhance the usability of the Sidewinder Turbo system. It works in conjunction with the Banks AutoMind Flash Programming Module to provide multiple programmable features that can be controlled directly from the 5-inch color touchscreen. The Banks iQ provides vehicle information, including fuel economy, performance tuning, performance testing, diagnostics, navigation, control modules, backup camera, hands-free phone operation (Bluetooth), media player, digital gauge package, and more.

The digital gauge feature of the Banks iQ is great. The Jeep Wrangler factory gauge cluster offers minimal engine information, but the Banks iQ can report on just about every vital engine function in addition to offering a great deal more. You can set audible alarms, read and clear trouble/diagnostic codes, log data, and measure horsepower and acceleration. Additionally, trouble codes are defined in plain English, not just codes, so you don’t need a factory manual, or a trip to the dealership, to know what you’re looking at. The iQ also uses a built-in Windows CE operating system that lets you view your Microsoft Office files and manage data. The digital gauge feature of the Banks iQ is great.

The Banks iQ also incorporates a navigation system complete with compass, elevation, mapping, and GPS speed correction. The iQ can be mounted in a variety of locations, including this cool dash mount that also includes mounting provision for the boost gauge. With traditional flash program technology, you unplug the unit and stick it in the console or glovebox until next time. With the Banks iQ, you can tune your programming and constantly monitor and adjust engine functions, all within easy sight/reach of the driver’s seat (Banks, of course, recommends using the touchscreen function only when the vehicle is stopped so as not to distract from driving).

We took a 4.0L Sidewinder Turbo-equipped TJ Unlimited on a 100-mile highway journey to test its ability. It conquered the pavement with ease, tackling steep grades without so much as a hiccup. On the trail, the Sidewinder Turbo continued to impress, wailing its way through difficult terrain. With the massive increase in torque, in most cases we were able to remain at idle and let the 4:1-geared transfer case pull the Jeep over obstacles.

This is no seat-of-your-pants power-up kit that shows meager improvements in power and torque or makes your exhaust louder so you think you’re going faster—you will notice the improved performance immediately. If you don’t believe it, let the dyno numbers do the talking. With the 4.0L Sidewinder Turbo kit installed, the 4.0L delivered a gain of 66.1 horsepower at 4,400 rpm (201.6 horsepower compared to 135.5 horsepower stock) and 83.7 lb-ft of torque at 3,200 rpm (249.4 lb-ft compared to 165.7 lb-ft stock). That’s a 48 percent gain in horsepower over stock and a more than 50 percent gain in torque. In fact, torque output with the turbo at 1,600 rpm is greater than the peak torque in stock condition. This aggressive torque profile is ideal for rock-crawling and trail-running scenarios.
