Stronger Than Ever Braised Hoses From Goodridge
IF YOU’RE RUNNING A COMPETITION TRUCK, chances are you have Goodridge hoses somewhere in it. Even if you’re not, you might well still have. They’ve got quite a name, well-earned, in the racing world across all of motorsport – but to their credit, they’re not resting on their laurels. Which sounds mildly painful anyway.

Breathe the Pressure...
IF YOUR VEHICLE is occasionally losing its cool, there could be an issue with the cooling system – like, duh, as any obnoxious ten-year-old would point out. Having worked that out, what do you do now? Short of putting it into the dealership for an expensive check-up, there’s not much...

Much-Needed Thermal Protection for Jeep Engines
THE 4.0-LITRE STRAIGHT SIX engine fitted in the Jeep Cherokee and Wrangler was a bit of a legend. Not just for its cheerfully revvy power, nor indeed for its equally cheerful willingness to consume petrol, but for the fact that it’s one of the most reliable units ever fitted in...

More Power For Less Fuel From Timber Trail's Boost Pin
If you’ve got a Tdi engine and would like it to dish out more power while using less fuel (and who wouldn’t), the Timber Trail Boost Pin should be right up your street. Because that’s exactly what it promises to do.
-
New Kit For Vitara Weber Conversion
WHEN YOU BUY AN EARLY SUZUKI and want to take it off-road, one of the first things you’re likely to do is chuck the original carburettor in the bin. In its place, you’ll put one – usually a Weber – that doesn’t starve the engine of petrol first time you try...

Puma tuning? It's in the box.
THE ART OF TUNING used to be all about things like shaved heads and ported manifolds, but on modern engines the commonest thing to do is just shove in a bit of software. The results can be startling, of course, particularly on diesels which come out of the factory developing...

Handsome, hardcore header tank
THERE’S NOTHING QUITE LIKE A BIT OF POLISHED ALUMINIUM to light things up in a Land Rover’s engine bay. Obviously, though, it only counts if it also has a function, but that’s fine – we don’t drive these things because they look pretty, do we?

Hydrogen fuel cell on trial at 4Most4x4
GETTING 4X4S’ ENGINES TO USE LESS FUEL is the modern equivalent of turning base metals into gold. Everyone wants to work out how to do it, people are convinced that cracking the secret will make them rich and, as it turns out, the best answer normally turns out to be...

Heavy-Duty Clutches for TDIs
If you run a 200 or 300Tdi Defender, Discovery or Range Rover, it’s probably occurred to you at some point that a heavy-duty clutch wouldn’t go amiss. Our own editor is prone to some very dark mutterings when this subject comes up.
-
Keeping Crud Out Of Your Carbs
Not many off-roaders run carbs these days, but if yours is a Weber from the 45DCOE, 44/48IDF, 48DCO/SP or 48IDA ranges you might forever be looking at those big, wide air trumpets and cringing at what could get sucked into them.
-
300TDI EGR Removal
We all know about EGR valves – annoying items to be removed and disposed of immediately. Standing for Exhaust Gas Recirculation, this little gadget aims to reduce nitrogen oxide emissions by recirculating some of your truck’s exhaust gases back into its engine.

Megasquirt Is Here To Save The World – From The Curse Of The Scissor-Stay...
There are lots of reasons to love the Land Rover Defender. But there are lots of reasons to hate it, too, and one of them is the scissor-style bonnet stay that’s left so many owners swearing loudly.
-
120-Amp Alternator for 200Tdi
As the Defender gets ever more complicated under the bonnet, and Land Rover moves towards replacing it with a vehicle most traditional owners assume will be even less DIY-friendly, rebuilding old ones is becoming more and more popular.
-
New Tuning Options For Amarok
If you see a nearly-new 4x4 being modded for off-road use, what’s it most likely to be? Land Rover Defenders usually take a few years before the fun starts, and with Jeep Wranglers it’s longer still. As for everything else, it takes so long most of it’s out of production now.
-
Twin-Weber Manifold for Samurai
There's not a lot of Suzuki Samurais left that haven’t had major work done to their original 1.3-litre engine (such as removing it altogether for a Vitara unit or Vauxhall diesel instead). But if you find one still in factory form and fancy turning it into even more of a...
-
Made-To-Measure High Tension Leads
Formula Power has launched a new range of HT ignition leads which are made-to-measure for individual vehicles – meaning you don’t have to cut them to length when fitting them. Made from high-quality 10mm cable, they promise low resistance and, therefore, a good, strong spark at the plug.
-
Jenvey Throttle Bodies for V8s
Got an American V8 in your truck? If so, chances are you’re running Weber IDA downdraft carbs… but chances are also that what you’d really like to do is put it on fuel injection.
-
New Tuning Boost for Hard-Working Diesels
Diesel tuning has become a very big deal in the last decade or so, and the latest name in the market has something special to offer – because it’s been designed specifically for oil-burners. Launched at the end of last year, Varra is ‘a tuning solution specifically for diesel vehicles’...
-
What a Cool Idea, etc...
Design Engineering’s Chill Charger is an intercooler additive intended to improve heat transfer. It claims to ‘lower air intake temperatures while also protecting the intercooler core from corrosion, electrolysis and harmful mineral build up.’
-
Stroker Kit for Toyota Powerhouse
The last-generation Toyota Supra is best remembered as an example of how much harm the chav scene is capable of doing to a perfectly good car. But the 2JZ straight-six twin-turbo under its bonnet was a legend, cranking out 320bhp and still more in the way of torque, and there’s...

Keep Your 4x4 Cool Under Pressure
We’ve written about hundreds of modded 4x4s and special builds down the years. And of all the teething problems people tell us they had with them, one of the most common has got to be that the cooling system didn’t work.
-
Lava Rock Heat Shields
Exhaust heat shields aren’t exactly the stuff of off-road legend. But when your engine’s giving it everything while you crawl forward at half a mile an hour on the end of a winch cable, keeping on top of the temperature under the bonnet is definitely the stuff of reality.
-
Heavy-Duty Duct Hoses From Webcon
A new range of heavy-duty duct hoses has been released by Webcon, aimed specifically at off-road enthusiasts. Made from durable rubber, this has been designed for use in extreme conditions, and its 70mm inside diameter ends can be used on round or oval plenums and air filters.
-
Multi-Purpose Tanks From Viper
Viper Performance doesn't specialise in off-road stuff, but its new range of small alloy tanks could certainly rock your world if you’re doing major jobs beneath your truck’s bonnet. Available in anodised black or polished natural aluminium, these are intended to be used as reservoirs, breather tanks, swirl pots and...
