Where do you stand on the subject of automotive purity?
Is a automotive only ‘correct’ if it’s a numbers-matching, unfettled example because it left the showroom floor? Does a tubular chassis with some fibreglass bodywork still count because the automotive it’s imagined to resemble? That is Speedhunters in spite of everything, so I presume that I’m writing to an open-minded crowd who enjoy a modified automotive. But, where do you stand on a reproduction, or tribute?
Harjun Singh‘s 1992 BMW isn’t an M3, having began life as a 318i, then covering only one,500 miles before being taken off the road and utilized by a school for educational purposes. But I’ll be referring to it as an M3 for the remainder of the article, for multiple reasons.
This isn’t Harjun’s first E30, though. “My first automotive was a red 316i, which I got once I was 17 years old. My dad had one back within the day, and I’ve all the time loved the form,” he explained.
“But it surely wasn’t long before I wanted more power, so I dropped in an M42 engine from a 318is. Then I began doing track days and wanted more power again, so I replaced the M42 with a 2.8L six-cylinder M52, which I did quite a lot of track days with. By the point I used to be at uni, I used to be doing track days every couple of months, and the 316i had an E46 M3 S54 engine in it, which I’d later supercharge for 550bhp,” says Harjun.
Then sooner or later out of the blue, a totally rust-free E30 318i shell appeared on the market with a full M3 exterior conversion having already been accomplished using real BMW M3 body panels. The previous owner simply lost interest within the project over the course of the transformation and decided to maneuver it on for a really reasonable price.
Harjun snapped it up, and in the mysterious way the world works, anyone then proceeded to hound him to sell the supercharged 316i he already owned. “I ploughed the cash from the sale of the 316i into this latest shell to get it finished, but this time it might need to be a four-cylinder engine, not a six.”
Although he loved it, regardless of what Harjun tried with the previous automotive, even with 550bhp it simply didn’t feel fast enough for him. A six-cylinder was just too heavy in an E30 shell.
Cue a Honda K24 engine with a Garrett G30-770 turbo attached to the side of it. Mapped to 550bhp with an 8,500rpm rev limit and an incredibly linear power curve, I can assure you that from the passenger seat at the least, this E30 feels very fast.
The fuelling requirements are met by the ATL/Nuke Performance competition fuel cell unit with integrated swirl tank and fuel pumps within the boot.
Cooling is taken care of by an E36 M3 radiator, Setrab oil cooler and a 600x300mm intercooler with 3-inch piping. The exhaust system is fully custom from the turbo to the guidelines.
A set of Ecumaster goodies control the E30’s solid-state electrical system, including the ECU itself, digital dashboard, GPS system and power management unit. “The PMU allows me to maintain stock controls, just like the wiper and indicators stalks, headlight and electrics. I wanted the automotive to still feel like an E30,” said Harjun.
This extends to creature comforts beyond electrical, with actual door cards and carpets to raise the cabin beyond that of a stripped-out track automotive.
Sure, you’re sat in a pair of Recaro SPG bucket seats with TAKATA Racing harnesses, but there may be also a pair of LED lights mounted to the roll cage to light up the cockpit and the boot. Peek past the cage and also you’ll see the brand new roof’s carbon fibre weave.
The M3’s real party piece, nevertheless, is the driveline and suspension. “I’ve owned an F80 [M3] since across the time of the supercharged E30, and I absolutely love the rear end feel on course. So I made a decision to stay the entire rear end into the ‘M3′,” Harjun explained.
Yes, the rear subframe, aluminium uprights, suspension arms and multi-link geometry are all directly taken from a 2014+ F80 generation BMW M3. A Drexler limited-slip differential is nestled within the subframe, driven through a 5-speed E36 M3 transmission. The AST coilovers and subframe pick-up points are tied into the roll cage, while the rear inner arches have been tubbed to accommodate a wider and taller wheel and tyre setup at a low ride height.
Don’t think the front has escaped any kind of special treatment either, because the BMW nerd in me is delighted to report that Harjun has fitted real Group A touring automotive magnesium uprights in addition to adjustable billet aluminium front arms from MRT. Quantum coilovers complement the AST rears, fitted in raised suspension turrets and with separate reservoirs at each ends of the automotive and spring rates of 14kg/mm and 12kg/mm front to back.
BTCC-spec 6-piston AP Racing callipers sit over 368x35mm front discs, while the rear has actually been downsized from the OEM F80 setup to Porsche 4-piston Brembo callipers with 294mm discs. A Tilton non-servo pedal box connected to an MK60 ABS control unit ensures reliable braking with strong pedal feel.
Visually, Harjun’s M3 carries loads more presence than a standard E30 M3, though it’s not noticeable to the untrained eye. The explanation being, the M3 box arches weren’t wide enough to contain the F80 rear end – even with the tubbed inner arches – so an ever wider set has been fitted front and rear adding 140mm to the automotive’s width. These complement the carbon fibre wing and Gurney flap.
7twenty wheels in 18×9.5 and 18×10-inch fitments fill the arches, but will only achieve this until a set of 5×120 RAYS Volk Racing TE37s in the best size and offset for the pumped bodywork come up on the market. Harjun switches between semi-slick, slick and wet tyres depending on the weather and intended use.
What Harjun has created here is his own tackle the proper E30. A smattering of the most effective OEM parts from various eras, combined with other parts that far surpass what an E30 M3 ever was. And don’t forget the inspiration from a few of the biggest M3s to ever grace the web.
To complete, let’s circle back to my opener, and I’ll answer my very own query. It will take an exceptional machine for me to put my prejudices aside and embrace a ‘homage’ with open arms.
This is that exceptional machine.
