    ‘TAKE TWO’ / #BMW-E21 / #BMW-E21-M52 / #BMW-3-Series / #1982 #BMW-316-E21 / #BMW-316

    BMW E21 - E21s look great as standard – they look even better dropped over a set of Rotas and packing a 2.8 M52 lump! Mark Brown’s first foray into BMW E21 ownership ended in a fiery, frustrating mess, so he set out to go one better with his second example – we think he might just have managed it! Words: Jarkle. Photos: Rick Davy.

    BMW can stake a fairly watertight claim to have invented the concept of the big-power family saloon with their original 2002 Turbo, a car that paved the way for all manner of M-power Munich legends like the E30, E36 and the even larger 5 and 7 series cars. The fact that #BMW has long prided itself on producing a range of potent straight six, V8 and even V12 motors has created a somewhat unexpected upside though, and that’s that these motors can, with a bit of thought and a lot of elbow grease, be transplanted into cars lower down the range. Fitting more modern M engines into base spec BMWs isn’t exactly a new practice but it is something that never ceases to amaze, particularly when you lift the bonnet and see a relatively new motor transplanted into a car that rolled off the line when the Cold War was still raging.

    Mark Brown knows a thing or two about squeezing modern powerplants into retro BMWs, with this car being the second E21 to have benefited from his spannering skills. The first one, an orange E21 that eventually found itself running E36 power, sadly went up in flames in spectacular fashion about three years ago, an experience that must’ve been made all the more sickening for it happening on his drive.

    “It’d always been a fairly temperamental car and had suffered from electrical gremlins in the past, but I never expected it to do that,” he explains with a grimace. “I’d started it and doubled back to my house to get something, then turned round to find my neighbour frantically pointing at the flames. It burnt out very quickly.”

    Evidently not one to mope around or drag his heels, Mark opted to cure the pain of losing his beloved E21 by throwing himself headlong into another Munich-flavoured project, the one that eventually culminated in the car you see here. Bought by an Australian in Spain (hence the right hand drive layout), the car slowly made its way north under the ownership of various individuals, spending time in the Channel Islands before finally finding itself in Scotland. It was still there when Mark came knocking and before long the beige car was in bits, totally stripped and prepared for shot-blasting. It was only then that Mark could truly appreciate the gem of a car he’d stumbled upon; it was totally rot free, had covered a mere 50,000 miles and was rock solid in every respect. The perfect project in other words.

    “The whole thing was made much easier thanks to help from my friend Mick Rogers of Pristine Bodyworks. He’s a bit of a BMW specialist and has owned E21s himself, so it did make finding parts a little easier and problem solving that much swifter – two heads are better than one.”

    At this point Mark was fairly certain he wanted to repaint the car in some kind of orange hue, with the vibrant ‘Fire Orange’ supplied on the limited edition three series GTS being the most likely candidate. Actually tracking down the paint in any volume proved trickier than expected though, and when the trial paint reacted badly with the engine bay, well, then it was time for a rethink.


    “I pretty much decided to paint it in Laguna Seca Blue there and then, it was a spur of the moment call and one that I think went really well.” We’re inclined to agree with him. Mick’s contacts in the BMW world eventually unearthed the powerplant now found under the bonnet of Mark’s E21, the M52 six-pot from a 2.8 E36. All manner of BMW engines have been stuffed into the bay of the E21 over the years but we think Mark’s done the right thing by sticking to a six cylinder. For starters it’s the engine that’s best associated with fast BMWs and one that delivers a very handy 228bhp to the rear wheels, plus there’s the fact that getting an E36 motor into one of these isn’t a process that requires extensive surgery, it simply drops in using the mounts from the 323. It can also be used in conjunction with the E20 E36 gearbox, though Mark admits that he used custom mounts to get it sitting exactly where
    he wanted.


    “I was considering the bigger S50 M3 engine for the 282bhp it’d bring, but in the end it made more sense to stick with the 2.8. For starters it was a known, low mileage engine, plus there’s the fact that the half-shafts are a known weak spot and start throwing in the towel over 250bhp.”

    Not that Mark’s in any danger of being stranded by a transmission failure any time soon, not with the E21 now running the tough as nails differential from an E12 535i, a unit that’s so far proved more than up to the task of dealing with anything thrown its way. Discussing the build with Mark you’re struck by just how easy it all sounds, something that the man himself is keen to highlight. “The engine conversion went really smoothly, and the bodywork was simple because it was pretty much perfect at the start,” he laughs. “In fact the only really tricky bit was sorting the brake servo out and making it work in a reliable manner.”


    BMW might have a reputation for engineering excellence nowadays but back in the 70s when the E21 was first penned things were apparently a little more relaxed, and when it came to producing a right hand drive version it’d probably be fair to say that they cut a few corners. A spaghetti-like maze of cables, junctions and wires transferred braking force from the servo mounted on a piece of iron at the front of the engine bay to the bulkhead, and though this arrangement worked very well three decades ago, by the time Mark got the car it’d begun to show its age.

    “Finding the correct remote servo to use with a dual servo brake setup proved to be one of the toughest aspects of the whole project, mainly as actually tracking one down was an utter nightmare! In the end we rebuilt and serviced one to cut down on delivery time, but we still had to redesign the whole brake system.” With the bulk of the head-scratching work done and dusted, Mark turned his attention to other, less pressing aspects of the build.

    The standard 13in steels BMW bolted to the hubs in the mid 70s were entirely typical for the period but didn’t look quite right once the car had been lowered on coilovers all round, hence the decision to swap for Rotas in 9x15in flavour. The idea to paint them in black with a gold overlay was actually drawn from one of Magnus Walker’s Porsche 911s and is, we think, one of the standout aspects of the whole build. Rotas aren’t exactly a rare wheel in the old car world (and for good reason), but the ones on Mark’s car look utterly different thanks to their interesting finish.

    Then there’s the interior, an area where the age old adage of ‘less is more’ rings true. It isn’t stripped out to bare metal, dozens of glaring gauges don’t litter the place and you won’t find an insane, FIA-pleasing cage encroaching on the front seats. What you will find are a pair of natty Recaro buckets formerly housed in an Audi (and bought for a very reasonable sum), a small race wheel, oil pressure and temperature gauges discreetly tucked away and a subtle rear cage with the carpets modified to fit. It’s the perfect blend of parts for a car like this, one which will spend the majority of its time on roads, not race tracks.

    The car finally came together a number of months ago and was immediately pressed into service, Mark using it regularly throughout the summer and taking the time to appreciate and enjoy the fruits of his and Mick’s handiwork. He then made the painful decision to sell it on and move to something else, specifically a bright red E30 M3. Mark makes no qualms about it being a fraught call and certainly not one he took lightly, but the fact that, in his words, he’ll never be able to afford an E30 M3 ever again, sealed the deal. The E21 has since gone on to delight its new owner and Mark, with his E21 itch well and truly scratched (for now at least), has moved onto BMW pastures new.

    “The engine conversion went really smoothly, and the bodywork was simple because it was pretty much perfect at the start.”

    Not a lot of weight, and over 220bhp means that tail-out antics are only ever a twitch of the foot away.

    M52 engine was a surprisingly simple swap – helped no doubt by being fitted into an immaculate engine bay.

    Born Again Hard

    If you like sleepers, you’ll love this Belgian E30, which packs an S50 punch and knows a thing or two about burnouts… The early #BMW-316-E30 was a miserable model with moped-like power, but a quick E36 M3 engine swap and some chassis sorting sees this old classic re-born into a devilish sleeper. Words: Iain Curry. Photos: Kevin Raekelboom.

    At first glance, it’s hardly the last word in sexy. There’s the embarrassing 316 badge on the bootlid, worrying shut lines, gold/silver paint that could happily pass for metallic beige, and a worn cloth interior featuring an abundance of brown. This is not typical PBMW fodder I hear you cry. And you’d be right, except this is exactly the sort of BMW that occasionally gets us all excited, simply because of the well-hidden secrets that lurk within. Sleeper? Oh yes.

    There are the odd exterior clues suggesting this well-used #1983 E30 #BMW-316 isn’t quite as granny-spec as it first seems. There are the 17-inch BBS rims with semi-slicks for one, and they certainly sit quite snugly under the arches of this 30-year-old 3 Series classic, suggesting a reasonable amount of suspension fettling. Then there’s the front mount oil cooler and fruity-looking exhaust poking out from under the rear bumper and riding very low to the ground. Just what is this thing all about?

    First of all it’s been created by one of our continental European friends, in this case a Belgian 26-year-old called Kristof Dhuyvetter, better known by his nickname ‘Stovie’. Like all good Belgians, Stovie has a soft spot for techno and house music, waffles, over-strengthened beer and modifying his BMW even though Belgian rules on such things are unnecessarily harsh. Keeping your car sleeper style in this country is certainly favourable, and Stovie has played a blinder here.

    Lurking under this E30’s beigey bonnet sits a transplanted 3.0-litre straight-six from one of the earlier E36 M3s. Okay, so we all get more turned on by the likes of an E60 M5’s V10 stuffed into an E30, but this conversion is far more viable for a DIY modifier such as Stovie. And a darn sight cheaper, too. The S50B30 engine from the 1992-1995 E36 M3 can be picked up for not much coin these days, and the incredible upping in power from a standard 1983 E30 316 turns this car from an embarrassment into a veritable weapon.

    From the factory, these old 1.8-litre 316 models were good for a paltry 90hp – buyers were certainly keener on the BMW badge rather than decent performance to match the rear-wheel drive layout. These early entry-level E30s were still using the old M10 four-cylinder donks, which had been in service since 1962, so if ever a car was ripe for an engine conversion it was Stovie’s.

    “I bought the car about 160km from my hometown of Anzegem,” he said, “and I drove it home at full speed trying to blow up the engine. Unfortunately, I failed.” Not the usual way people treat their recently bought car, but Stovie had bought the old E30 specifically for modification. “A #BMW seemed the best choice for a conversion after I saw such potential on YouTube movies,” said the tyre centre manager who has previously modified a number of VWs and a Mercedes.

    “I needed rear-wheel drive, plenty of speed and, of course, something that not everyone has,” he said. Well, a brown-interiored 1983 316 is certainly not common on our scene, but you could just smell the potential here. “I immediately got the car registered and on that first weekend I started removing the engine. After it failed to blow up, I managed to get €200 for it. I then gradually began dismantling everything I no longer needed, and moved the new engine into place on an engine hoist.”

    Stovie had bought a 286hp E36 M3 six-cylinder along with the car’s five-speed manual transmission and its complete wiring harness. He managed to complete the bulk of the engine work himself, but enlisted the help of Belgian tuner and ECU remapping expert APEC to replace the engine’s troublesome Vanos system (many E36 M3 owners will sympathise with this) and do a custom ECU remap to find a few extra horses. With a custom exhaust manifold and full system plus improved breathing from a K&N pod air filter, this humble E30 316 was about to be presented with a 3.0-litre motorsport engine dyno’d at 306hp.

    Stovie informs us that fitting the M3 engine proved a bit of a chore thanks to the donor motor’s sump. He said he remedied this by fitting a sump from a 7 Series, but not before going through four others until he was satisfied. He made up some home-made engine mounts, secured the cogswapper in place and tucked away the wiring harness.

    But with over three times the power on tap now compared to the factory 316, taking this thing on the road with its original chassis and drivetrain would have been suicide. These old sheds had rear drum brakes for heaven’s sake. To ensure the components survived the first serious throttle flooring, Stovie fitted an E30 325i’s rear axle and custom-made his own driveshaft using parts from two E30s we never received in the UK: the awesome four-wheel drive 325iX, and the not-soawesome 324td diesel. In Stovie’s broken English we couldn’t quite get to grips with why this 325iX/324td hybrid driveshaft was created, but he assures us it is strong enough to take the power, and it has held together just fine so far.

    As for cornering and stopping, the ante has been raised significantly. D2 Circuit Series coilovers give the 316 a handling capability more in-line with an E36 M3’s performance, with the car’s rigidity helped by a front-mounted strut brace. At the moment the only anchor upgrade has been a set of E30 325i rear discs, but Stovie assures us 312mm discs will find their way on to each corner in the very near future.


    He needed to make sure such brakes would fit behind whatever aftermarket wheels he chose, as they’d certainly have no chance with the stock 316’s 14s. He chose 17-inch BBS CH-R rims which are a dramatic improvement for the exterior look of this body-unmodified E30, even if they do reduce the sleeper status somewhat. And if you wanted an indication of how this muscled 316 is used, just check out the rubber. Federal 595 RS-R semi-slicks wrap the BBS alloys, and Stovie tells us the grip from these boots makes it one of his favourite mods on the E30.

    As previously mentioned, the body has remained completely untouched, but there is a tell-tale front-mount oil cooler that inquisitive eyes will notice and wonder what’s afoot. As for the cabin, well, that’s another wonderful throwback to the early 1980s, and although a little worn in places, the retro style of its brown cloth seats, carpets and doorcards have quite rightly not been tampered with. A local company called Lectromotive custom-built a nice gauge pod for the centre console, while adding an E30 M-Tech steering wheel and five-speed gear knob results in a slightly sportier air to the interior.


    Stovie plans to continue modifying his 316, but is reluctant for it to move away from its Q-car status. “It can be very useful, looking how it does,” he said. “I’ve been stopped by the police before for driving too fast, and I said ‘but it’s just a 316 with a broken exhaust’. They believed me and let me drive on. I also like it when people say ‘for such an old bucket it is tremendously fast.’”

    In the pipeline are the new brakes, a roll-cage, BBS RS wheels and perhaps a supercharger kit for the 3.0-litre as well. Stovie likes the way it drives at the moment, but wants to address the weight balance (or strip it) to cure its understeer tendencies. He mentioned the car rides very low and there is some rubbing in the wheel arches, and that the 7 Series sump he took ages to find is at risk with the coilovers wound down.

    Has it all been worth it? After all it still has the outward appearance of an old 316 with a nice stance and some fancy rims. Well, Stovie did some sums and quickly calculated he’s already put €12,000 into the old #BMW-E30 not including the labour time, and that can buy a very tasty performance BMW – an E36 M3 or E46 M3 with change left over. But that’s not the point really. Would you suspect this old sleeper if you came up against it at a set of lights? With treble the power over a standard 316, Stovie, we salute you.
