Track-Spec, Street-Driven: A 600hp Twin-Turbo Porsche 912

Track-Spec, Street-Driven: A 600hp Twin-Turbo Porsche 912

I’ve got great respect for people that restore old classics back to factory, or better-than-factory condition. Restorations can easily consume hundreds if not thousands of hours, and not just in physical labour, but research and parts-hunting time, too. And then there’s the actual cost, which can be eye-watering depending on the scope of the project. Being passion-driven, the end results are almost always worth it, though.

While I can appreciate a perfectly restored classic, I’ve always preferred the more radical approach of taking something quite normal and turning it into something really special. The owner of this wild 1969 Porsche 912 obviously has the same mindset.

The Carrera RSR-style front bumper and 993 GT2-style rear wing set the tone for this hardcore build. As you’ll see, the 912 is filled to the brim with race parts – as you’d expect for a car that sees plenty of track time – but it’s also been built road legal here in South Africa.

Perhaps more than the aero additions, the first thing that catches your eye is the iconic Rothmans Porsche livery, as worn by the 956 and 962C Le Mans racers in period. It’s a great look here, but what makes the livery extra special is the fact that it’s been painted. A wrap was simply never going to cut it.

As you’ll already have deduced from the title, this is no sheep in wolf’s clothing, though.

While the 912 came with a four-cylinder engine, there’s nothing ‘numbers matching’ about what lives under the rear deck lid now. Instead of a paltry 1.6L unit, there’s a 3.4L powerhouse built from a 3.0L 930 mill.

Internally, you’ll find 98mm Capricorn cylinders, JE forged pistons, Pauter I-beam rods, GT2 Evo cams, upgraded valve springs and titanium retainers, and ARP studs for the ported heads. Externally, there’s a modified 911 Carrera intake manifold, Bosch Motorsport injectors, a GT3 oil pump, Goodridge fittings, and a custom radiator underneath the car. But the real party piece – or pieces, should I say – are the twin Garrett GT2971R turbos with 46mm wastegates.

They’re fully on show out back, and boy do they look good finished off with a custom titanium exhaust system.

Firing orders come from a MoTeC M84 engine management system, and power output is around 600hp on 1.2bar (17.6psi) boost – a solid number for a 51-year-old car. This power is transferred to the wheels through a 915 gearbox, which has been shortened, cut and welded, and paired with a GT3-type clutch and lightweight flywheel conversion.

Having so much performance available at a squeeze of your right foot would be pointless if the chassis wasn’t up to it, but nothing has been overlooked in the handling department with custom Advanced Suspension Technology (AST) motorsport coilovers at the heart of the upgrade. To get to a stop, there’s Brembo rotors and callipers, and a custom retrofitted ABS braking system. Depending on use, the split rims of unknown origin are either fitted with road or track (slick) rubber.

Inside, the interior has been modernized with custom leather-trimmed Sparco Pro 2000 seats, a SCHROTH harness for the driver, OMP steering wheel on a quick-release hub, and a MoTeC C127 digital dash.

But just in case you forget you’re driving a race car while out on the road, there’s the full roll cage, carbon fiber switch panel, carbon-Kevlar panel trim throughout, and an adjustable Tilton pedal box to remind you of the 912’s motorsport underpinnings.

This really is a great example of having an idea and executing it with success. So much work has gone into this half-century-old Porsche, but I’m sure all the effort and numerous challenges along the way have been worth it. The fact that this is in all honesty a full-on race car that’s brilliantly still road legal is just the cherry on top.

BMW 530 MLE: The First True M Car

BMW 530 MLE: The First True M Car

Let’s Race

Most people think that the legendary M1 was BMW’s first M car, but they would be wrong. That honor is actually reserved for the BMW 530 MLE (Motorsport Limited Edition).

In the mid-1970s, BMW South Africa wanted to compete in the country’s Modified Production racing series. There was only one problem – they needed a competitive car, which didn’t exist at the time.

A call was put through to Jochen Neerpasch, the head of BMW Motorsport and a highly accomplished race driver in his own right, and the wheels were put in motion for a couple of E12-based competition cars – and a small run of production road cars for their homologation.

Both motorsport machines were immediately successful, winning 15 of 15 races in the first season. They dominated the series for the next three years too, and remained competitive until retirement in 1985.

While the race cars were very cool, today we’re looking at one of the rare road cars that BMW South Africa needed to build in order to go Modified Production racing in the first place.

One For The Road

In order to meet the homologation requirements of the Modified Production rulebook, a minimum of 100 road cars needed to be built. It’s reputed that between 105 and 110 examples of the BMW 530 MLE were produced and sold to South African customers in 1976, two years before the iconic M1 was launched.

Due to sanctions during apartheid, the South African public were starved for performance cars, hence the reason why so many ‘SA special’ cars – especially BMWs – exist. Think, the 333i, M745I and 325is.

Although the road-going 530 MLE didn’t feature a full race engine, many competition-spec parts did find their way into the car, making it the first true BMW M car for public consumption, if only in one market.

stefan-kotze-speedhunters-bmw-530-mle 053

These were the first BMWs that were given the ‘M’ designation on their VIN plates.

Hand-built at BMW’s manufacturing facility in Rosslyn, Pretoria, E12 525 shells were pulled off the production line and given the full Swiss cheese treatment. To shed precious pounds, holes were drilled under the seats, through the parcel shelf, through the c-pillars and rear seat panel, and inside the bonnet. The clutch pedal and boot hinges were also drilled, all in the name of weight-saving. As this work was laboriously done by hand, meaning no two cars were exactly alike.

The 100-odd homologation road cars were all white with striping in the famous BMW motorsport colours. Exclusive to the 530 MLE was a special fibreglass air dam and boot spoiler, plus hand-cast rubber arch extenders. Luis Malhou, owner of Custom Restorations and also the owner of this particular car (chassis #21), says that some of the arches he’s removed from 530 MLEs still had normal flathead screws with wires welded into their slots to add strength and to hold the screws into their moulds.

The cars were all fitted with Scheel sport seats trimmed in blue velour cloth, and featured matching blue vinyl door panels. You also got an Itavolanti steering wheel and wooden shift knob denoting the 5-speed transmission’s dogleg 1st gear.

Electric windows, power steering and air-conditioning? Forget it.

Special BBS Mahle 14-inch wheels were created as one-offs for the 530 MLE, and then wrapped in 195/70R14 tyres.

stefan-kotze-speedhunters-bmw-530-mle 083

By the way, the 530 MLE never came with an ‘M’ badge, but seeing as it’s BMW’s first real M car – although unofficially – Luis felt it was quite fitting to add genuine old school ones to his car.

stefan-kotze-speedhunters-bmw-530-mle 065

At its core, the 530 MLE used the same 3.0L M30 engine found in previous generation E9 and E3 vehicles, but in this case it was tweaked with a hotter cam and high compression Mahle pistons, and fed by twin down-draught Zenith INAT carbs. The result was 147kW (197hp) and 227Nm, fed through a Getrag close-ratio gearbox and ultimately the rear wheels via a BorgWarner limited-slip differential. According to Luis, some cars had oil coolers too.

In testing, this homologation special could go 0-100km/h in 9.3 seconds, and reach a top speed of 208km/h (129mph).

stefan-kotze-speedhunters-bmw-530-mle 084

Subsequently, the suspension and brake systems were upgraded too. BILSTEIN shocks with firmer springs featured at all four corners, along with ventilated discs up front and solid discs in the rear.

Over the years, Luis has owned six 530 MLEs in varying states of condition, and restored three from the ground up. This specific car was previously owned by Luis’s father; he sold it in 2004 and Luis found it again in 2007 and bought it back. It was in terrible condition at that time, and it took some work for Luis to restore the car to its former glory.

Factory Finish

Luis’s restoration handiwork is so good, that when BMW South Africa was looking to add a 530 MLE to its own museum, he got a call. Initially, BMW SA wanted to by Luis’s car, and then Luis’s brother’s (yes, the Malhous own two), but that wasn’t going to happen.

In a stroke of luck though, Luis was able to track down chassis #100 (complete with matching-numbers engine), which had originally been owned by the 530 MLE race team’s manager, Peter Kaye-Eddie.

With Luis’s build team at Custom Restorations including four retired BMW employees who worked on the original 530 MLE project – William Mokwape, Walter Mahlangu, Jacob Matabane and Cassie Calaca – it took a full year for the job to be completed.

The complete nut and bolt restoration wasn’t an easy process, but the end result it simply stunning, as seen in the video above. This car could have easily been left to rot away, but now it has a safe home alongside some of BMW South Africa’s special cars in its local museum.

Both on the track and off, the BMW 530 MLE was a very special machine. In fact, due to the car’s popularity, a further 100 examples were made after the initial homologation run of white cars, but as these were built on the production line, weren’t given the lightweight treatment, came in different colors, and featured more creature comforts, they’re seen as a watered-down version, and therefore are far less sought after by collectors.

But thanks to passionate owners like Luis, the legend of the original BMW 530 Motorsport Limited Edition lives on.
