Ford Ranger Gets A Power Kick With Texas Walker Conversion

Ford Ranger 3.2 Performance Plug And Play Unichip

Estimated Power Gains:

147kw >> 170kw

470nm >> 570nm

Steves Auto Clinic is set to rewrite the rulebook on what type of power you can expect from your Ford Ranger 2.2 TDCi or 3.2 TDCi with the introduction of a Texas Walker conversion kit. The kit, which can be implemented in several stages, holds the promise of completely changing the driving dynamics, engine power and fuel consumption of the Ranger, depending on which parts of the conversion you fit and which map of the performance chip you select. Do your homework well: Unichip vs. other performance chips on the market.

Possibly the most important and first part of the conversion is the fitment of a Unichip performance chip and plug and play system from the team at Dastek Power. The chip has been tested comprehensively on the two Ford TDCi engines and are optimised for South African driving conditions.


With the Unichip and plug and play system on board Ford Ranger owners can expect up to 20% more power and 25% more torque for the 2.2 TDCi engine and up to 20% more power and torque on the already impressive performance figures of the 3.2 TDCi Ranger.

Free Flow Exhaust

The next stage of the Texas Walker conversion adds extra cooling through the fitment of a custom made Power Cooler to the 3.2 Ranger. This intercooler allows virtually double the amount of cold air into the engine, which allows the engine to breathe and perform even better. With this Power Cooler fitted, the team at SAC can also add a Power Switch. Together these two additions will give you complete control of your engine’s character from inside the cabin.

Says Stephen Fisher, founder of the Steves Auto Clinic group and well-known engine tuning wizard: “Our comprehensive testing of both the 2.2 litre and 3.2 litre Ford engines have confirmed that there is significantly more power available under the bonnet. By fitting a Unichip Plug and Play system we are able to tap into that power and, with the help of a Power Switch, the owner can dial into the power or choose a map that favours power, more technical or more frugal driving.”


The second stage of tune on the Ranger Texas Walker Unichip system with Power Switch offers five different driving maps. In its first setting, the Ranger enters a security mode, which renders the engine powerless and the vehicle unable to drive.

Notch the Power Switch up to the second setting and you will reconnect with your standard vehicle, as this setting mirrors the exact engine settings of the standard 2.2 or 3.2 engine. The third setting was created in response to many SAC customers’ need for better fuel consumption in city driving circumstances. In this setting the Ranger will deliver power gradually, with the benefit of better fuel consumption and greater travelling distances between fill-ups immediately evident.


The Texas Walker Unichip conversion adds two more unique engine settings that should be favourites among Ranger owners. The first of these two additional settings is an off road and towing option that changes the engine’s power band to deliver its peak power at lower engine speeds. For lovers of technical off road driving or people who regularly tow a large boat or caravan, this setting is ideal.

Intercooler Upgrade

The primary function of an upgraded intercooler is to improve on the cooling efficiency over the standard cooler.  This means that the entry air temperature needs to be dropped as far as possible (more than the standard cooler) at the exit of the cooler without compromising or interfering with the flow and or charge pressure- the boost. Our upgraded intercooler has been through very strict Research and Development procedures and has been properly tested to meet the requirements of today’s technologically advanced and challenged Diesel Turbo vehicles.  The new cooler mounts in the same location as the standard one and in most cases, utilizes the original pipes and clamps. (With the exception of the D4D Hilux that goes from top mount to front mount) The intercooler upgrade is an integral part of the performance enhancement process that optimizes the volumetric efficiency of a TDi Bakkie. In short, the way that the cooler works is to cool down the air as much as possible – that is being produced by the turbo charger (that heats up when compressed).  Fast-hard riding as well as towing causes thermal engine temperature creep which eventually spirals out of control and deteriorates your vehicles engine condition and shortens its life.  It’s not only about more power, sometimes we need to consider what the engine is being exposed to and have some mechanical mercy. Our upgraded intercooler is an absolute “must have” product for those performance fanatics out there, or the people that want maximum power at safe levels.

The last setting available through the Power Switch is the jewel in the SAC Conversion’s crown. Opt for this engine map and suddenly all of the hidden power in the TDCi engine comes rolling in like the dark clouds before a Highveld thunderstorm.

“Both the 2.2 and 3.2 engines have a large reserve of extra power that we have been able to safely and reliably unleash with our performance chip,” says Fischer.

Book the car inAt Steves Auto Clinic these conversions are done by a trained dyno tuning specialist, who maps engine performance in three dimensions against engine speed, load, fuel mixture, temperature and a host of other metrics. In doing so, the team ensures that each Ranger is optimised perfectly, with the vehicle’s age, condition and specific engine capabilities in mind.


For enthusiasts who would like to increase engine performance and efficiency even further, SAC has developed a brand new 76 mm performance exhaust system for the Ranger. This system, which has been developed specifically for the Ranger, ensures improved back pressure and a clear exhaust path to free valuable extra horsepower on the 3.2 TDCi engine.

“Every Steves Auto Clinic is equipped with modern diagnostic equipment and a dynamometer with which we test and fit any performance upgrades on the Ranger. With this equipment on hand you can be sure that we will safely and reliably add significant power and the choice of many different driving modes to your Ranger, so come in and have a chat with your local Steves Auto Clinic specialist,” says Fischer.

Bolt on exhausts

Gone are the days that you take your half a million-rand Bakkie to a corner exhaust shop for a cheap free flow exhaust. It’s fair to say that the bolt-on free flow exhausts of today at SAC have been revolutionized and are becoming more and more popular amongst the enthusiasts. It is no longer just a poorly welded and routed exhaust that rattles and knocks over every bump, it is a properly engineered, big bore, mandrill bent stainless steel-low restriction exhaust system.  It is manufactured in such a way to be a bolt-on fitment in a workshop with very little effort to ensure perfection. Seeing the exhaust system in its raw form, packed and laying on a shelf – it is clear to see that this is an export quality product that will be installed on your vehicle, and it will compliment without any doubt – the performance enhancement plug and play kit and or upgraded intercooler system in many ways – most of all the sound and power will be much improved.  The bolt-on exhaust system is routed along the exact same rout under your vehicle and hangs with similar brackets on the standard rubbers.  The heat protection that has been provided by the manufacturer under your vehicle to protect the undercarriage is still effective and useful with the fitment of these bolt-on exhaust systems. So, if you want the ultimate Bakkie performance enhancement package speak to our sales and service advisors about a bolt-on exhaust system. Contact us today for your free quotation.
