With 900hp from an #N54 with stock internals, this E91 Touring is really reaching for the final frontier. Words: Elizabeth de Latour. Photos: RonV Photography.
The king of fast estates has traditionally always been Audi; its automotive back catalogue is filled with examples of big power load-luggers, from the legendary RS2 Avant, mental original RS4 and equally mental RS6s, though BMW has also had a go, with the E34 M5 Touring and E61 M5 Touring. These days, though, its given up on M estates, so the fastest way to transport dogs, children and sofas, possibly all at the same time, is in something with a turbocharged straight-six under the bonnet. For example, the F31 335d xDrive will hit 0-62 in 4.9 seconds, at which point you have to ask yourself: how fast do you really need to go?
Well, if your name is Marco van Weerd, then the answer is much, much faster than that. Marco’s steed of choice is an E91 335i M Sport Touring, a fine car powered by a fine engine and plenty quick in just about any given situation but, as we all know, the twin-turbo N54 has so much more to give… Marco bought the car three years ago, completely stock, but, with a couple of modified Japanese cars in his motoring past, it was never going to stay that way for long. “From the moment I bought the car, I began modifying it right away, starting with some standard upgrades like a JB4, downpipes, intercooler etc” but that was never going to satisfy his thirst for modifying and his hunger for power. You see, Marco wasn’t interested in owning just a quick car, he wanted to push the limits of the #N54 as far as he could and that’s exactly what he’s done, taking the 3.0-litre straight-six to a staggering 900hp. It takes just a quick glance into this E91’s engine bay to see how he’s done that: with an absolutely gigantic turbo strapped to the side of the engine but, what’s a little scary, is the fact that Marco has left the engine’s internals completely stock…
“I wanted to try and break the 1000 flywheel hp mark on a stock N54 because I want to be the one to set that record,” he grins, and he’s tantalisingly close. The key to that stratospheric power output is threefold, a combination of: massive turbo, fuelling mods and the right fuel. The pictures show a Comp 6465 but that wasn’t powerful enough for Marco, so since the shoot that has been swapped for a Precision 6466 turbo running at a heady 2.5bar, with twin Tial MVS wastegates leading to a pair of screamer pipes located under the car, with that torrent of turbocharged air being passed through a 190.5mm stepped intercooler from VR Speed Factory and into an Evolution of Speed intake manifold with six Bosch injectors. These are fed by an uprated fuel system running a Fuel-It Stage 3 kit consisting of twin Walbro 450 low-pressure fuel pumps plus upgraded fuel lines with a Bluetooth-enabled ethanol content analyser, necessary because the car has been set up by JB4 Tuning Benelux to run on E60, a heady mix of ethanol and 102 octane fuel. Further enhancements include cooler NGK 5992 spark plugs and a custom exhaust, consisting of a 3.5” downpipe leading to twin 2.5” pipes with twin electronically controlled cut-outs located before the rear silencer, and finished off with twin 102mm carbon exhaust tips.
You might be concerned that running that much boost through such a massive turbo means the engine is only heading in one, inevitable direction, but you needn’t worry as a forged engine is on the cards, at which point Marco’s power goal will change from 1000hp at the crank to 1000whp… When that happens, there will be a lot of transmission work going on because, at the moment, everything here, much like everything within the engine, is completely standard and that simply won’t do when the next stage of the project gets underway. In fact, only the standard brakes have been deemed unfit for purpose and have received a seriously substantial upgrade in the shape of a D2 Racing front and rear BBK, comprising 380mm discs with eight-piston calipers and 356mm discs with four-piston calipers respectively.
You might be expecting to find some sort of serious static suspension setup leaning far towards the performance end of the spectrum, but one glance at the photos will tell you that you’d be wrong. Marco has opted for a spot of air-ride, with an Air Lift Performance 3H kit handling the suspension duties and delivering some devastating lows when fully aired out, bringing this E91 to within a whisker of the Tarmac, the nifty controller mounted simply, just ahead of the gear lever inside the car. The interior itself has been left virtually standard, bar the addition of the M Performance gear selector and carbon roundel on the steering wheel, which has also been treated to an alcantara trim panel. What Marco has done is add some serious tech to help him keep an eye on what going on under the bonnet, with a Samsung tablet running the JB4 mobile app and displaying OBD controls and tuning plus a phone equipped with the Fuel-It app, displaying fuel temperature and ethanol content, with both pieces of tech connected to the car via Bluetooth.
While the engine and interior may have been left standard, the exterior has not and here Marco has taken the opportunity to put his personal stamp on the car and really make it stand out. “In my company I have my own car lift where I can work on the car whenever I want,” he says. “I tried to build the car all to my own taste and wanted to use custom parts you cannot buy everywhere,” which is why this E91 looks so distinctive. Up front, and giving this prefacelift E91 a fresh and fierce look, he’s fitted a custom 1M front bumper specially made to go with the facelift bonnet (complete with carbon roundel) and headlights he’s also fitted, and the bumper has been further enhanced with the addition of a custom carbon front lip with custom carbon winglets at the corners. There are matt black mirrors and the side skirts have been embellished with custom carbon extension lips while at the rear you’ll find a custom carbon diffuser and custom carbon fi ns at the edges of the bumper, with all-red rear lights adding the finishing touch. Marco’s custom approach to styling and inherent perfectionism and attention to detail extends to the engine bay, which has also been adorned with a selection of custom carbon parts along with a custom carbon strut brace. The wheels too are, naturally, completely custom items produced to Marco’s exact specifications, 8.5x20” up front and 10x20” at the rear, a striking twin seven-spoke design finished in Sepang bronze. You might think that would be an odd choice to go with such an extensively black exterior, but they really work and just add something to the overall look of the car and the size is perfect too. The extensive use of carbon fibre, the aggressive styling and the sheer blackness of the thing all combine to make this one of the most ferocious-looking E91s we’ve ever crossed paths with. It’s just so mean and intimidating, an utterly ruthless-looking machine and one that has more than enough bite to back up its substantial bark.
For most people, a 900hp E91 Touring would be their final goal, but Marco’s just getting warmed up and there’s a lot more to come. “I want to make a custom wide-body kit for the car,” says Marco, running through his future plans for the Touring, “another set of custom wheels, wider this time, at least 10s up front and 12s at the rear, and I’ll also build the forged engine I want so I can hit 1000whp and that will also need an upgraded gearbox, axles and diff.” Judging by what he’s accomplished so far and his dedication and determination to extract as much power as physically possible from the N54, we don’t doubt he’ll achieve his goals and the end result is going to be something truly out of this world…
