Stunning 800whp turbo M10-powered 2002 is like a gift from the gods…
With an astonishing 800whp from its turbo’d M10, this wild 2002 is about as quick as any sane person would want to travel. Words: Elizabeth de Latour. Photos: Christos Karagiorgakis.
2002: A PACE ODYSSEY
Think of Greece and you will no doubt think of crisp, white houses sitting before the bluest sea you’ve ever seen, beautiful beaches, and delicious food. Perhaps what you won’t think of is modified BMWs. However, having been to Greece on many previous BMW-based visits, we can tell you that there are some serious machines scattered across the country. And this right here might just be the most serious piece of German modified machinery that Greece has to offer. It belongs to Stavros Panagopoulos, who has owned it for ten years. This was, in fact, his very first #BMW : a humble 1602 that he found for sale near his house. As you can probably tell, it’s changed a bit since then…
Stavros says he entered into ’02 ownership with plans to make the diminutive classic just a little bit faster. And while he’s certainly achieved his end goal, and then some, he didn’t embark on a journey of turbocharged madness from the off; there were at least two slightly more sensible stages prior to what you see here. Things started off normally enough, with the 1.6-litre four-cylinder engine enhanced with twin side draft 40 carbs. And that was fine, but not quite enough for Stavros’s liking. So Stage two was a bit more dramatic. The original engine was deemed not quite large enough so it was removed and in its place went a more powerful 2.0, its potency ramped-up considerably with the addition of a 300-degree camshaft, Weber 48 DCOE carbs, MSD Ignition components, and a selection of other sexy engine enhancements. That’s pretty solid and we wager the car (that was now by definition a 2002) must have been a whole load of fun to drive and a massive step up over how it felt originally. And then something happened: Stavros decided that what he really wanted was an 800whp turbo conversion. Because, sometimes, that’s just what you need in your life…
As you might imagine, making that sort of underbonnet magic happen takes more than a little bit of work and the engine spec list reads like a who’s who of the performance tuning scene. It’s thorough and it’s glorious. It’s the modified BMW enthusiast’s equivalent of 50 Shades of Grey…
Step one, you’ve got to get your engine choice down. Stavros opted for the sturdy M10, which served as the basis for BMW’s insane turbocharged M12 motorsport engine as well as the S14, so it’s certainly up to the task of coping with a spot of turbocharging.
But the example nestling under this ’02’s bonnet is very far removed from your common-or-garden M10, as you might have guessed. There’s a lot in the engine bay, so much so that you can barely even see the engine, but if it looks impressive from the outside, there’s plenty to get excited about on the inside, too. 89mm CP forged pistons have been fitted, along with Carrillo forged rods, a custom reprofiled camshaft from Boubis Cams, and #VAC-Motorsports valves, rocker arms, valve guides and valve springs. Somewhere within the engine bay (you’ll have to take our word for it because it’s buried deep beneath seemingly endless pipework) sits the very core of all that power: an absolutely gigantic #Garrett-GTX4202R-turbo . This beast of a snail is rated up to 1150hp so Stavros has plenty of headroom, running as he is at around the 900hp mark, should he ever decide that’s not quite enough. This is useful, actually, as his next goal is to hit 1000hp…
When it came to getting everything squeezed into the engine bay, custom is most definitely the word of the day: the turbo feeds a HPS custom intake manifold via a suitably massive front-mounted intercooler and sits on a custom exhaust manifold that connects up to a custom exhaust with an external wastegate that exits through the sill just behind the passenger side front wheel.
The exhaust manifold and the turbo housing itself have both been treated to a Zircotec ceramic coating. Stavros has also had massive Bosch Motorsport 1600cc/min injectors fitted to supply enough fuel to keep the engine happy, along with a custom HPS oil pan. The whole lot is looked after by an Autronic SM4 stand-alone ECU.
Seeing as no one involved in the designing and construction of the ’02 family could ever have imagined that someone in the distant future would attempt to pass somewhere in the region of 900hp through the compact runabout, Stavaros has had to go to town on the transmission and chassis to ensure it didn’t tear itself to pieces. The gearbox is a five-speed manual Getrag unit from the E28 535i mated to a custom twin-plate clutch that can handle the immense amount of power and torque being developed by the engine, with an E34 M5 rear axle tasked with transferring everything to the rear tyres. On the suspension front, this 2002 has been fitted with E36 M3 underpinnings, including subframes and wishbones, with #KW coilovers up front and Bilstein dampers at the back. While it doesn’t take much to stop a car as small and light as a 2002, stopping one that’s travelling at close to the speed of sound does require something a little more substantial, and this example certainly doesn’t mess about. Up front sit AP Racing Galfer four-pot calipers clamping 305mm vented discs. The rear setup is no less substantial, with another set of AP Racing four-pot calipers wrapped around slightly smaller 255mm vented discs.
When it came to the exterior Stavros decided to keep things relatively subtle in as much that a casual observer might not be aware of what’s been changed but, at the same time, it’s clear that this 2002 is far from standard. It’s actually about as aggressive as a 2002 can really get. The biggest difference are those pumped-up arches, complete with sill extensions that fill out the flanks. They give the normally unassuming classic some real road presence. Having the wastegate exiting through the sill certainly doesn’t hurt, and neither does that fat, single-tipped exhaust pipe. Of course, fitting wide arches is one thing, having suitable wheels that are substantial enough to fill them is another matter entirely but Stavros’ choice definitely doesn’t disappoint, though it might raise a few eyebrows. He’s taken the classic cross-spoke look that sits so well with the 2002 and turned it on its head with a set of decidedly modern Work VS-XXs.
The 17” wheels are positively huge on the compact classic but they look fantastic, really filling out those big arches, especially with the car dropped low over the fat rubber. Even parts of the body that may look stock aren’t. For example, the bonnet and boot might appear to be relatively standard, bar the pins and catches, but they are both carbon fibre items, with twin fuel fillers on the rear deck for the bootmounted alloy fuel cell. The one thing the 2002 isn’t is heavy, so adding carbon panels and reducing the already low weight further still means that, with 800whp on tap, this car is absolutely insane – just in case you hadn’t gathered that already!
With a build like this the interior could go a number of ways: hardcore, stripped-out; stock and subtle; or, option three, custom, luxurious but still decidedly sporty – which is exactly what Stavros has gone for. The interior is dominated by those gorgeous Recaro A8 seats and both they, the rear seats, the doorcards, the steering wheel centre section, the gear gaiter and the handbrake have all been covered in the same delicious shade of caramel leather.
Something that’s easier to miss is the custom alloy roll-cage; it’s so well-integrated that, while you can clearly see the rear diagonal support, the sections that penetrate the dashboard (down into the footwell) and the rear parcel shelf are much more discreet.
Up front, the gauge cluster has been replaced with an AIM MXL digital racing dash while the centre console now resembles the flight deck of an aircraft rather than a car. Where the central air vents would have once been there now sits a quartet of custom-mounted GReddy exhaust temperature gauges and below that another custom panel that houses a Daemon boost gauge, A’Pexi turbo timer and fuel gauge and, finally, down in front of the illuminated gear lever, you’ll find a pair of GReddy pressure gauges.
We’ve featured some pretty wild 2002s over the years but this example might just ‘take the cake’. It’s an utterly incredible machine and we’re a little bit in love with it. We love how the custom wide-arches give the little 2002 a broad, square stance. We love the interior, with its blend of modern tech, race components and gorgeous leather. And we really love the engine; we doubt you’ll see a more complicated engine bay, there’s just so much stuffed under the bonnet. And to come away with 800whp from such a small engine and to have it at your disposal in such a small, lightweight car is utterly insane and, well, we love that too.

We see a lot of modified cars here at PBMW but a 1000hp E36 M3 is something that never fails to impress… Words: Elizabeth de Latour. Photos: Andreas Wibstad.
They say that you shouldn’t chase numbers when building a car. You should build a car that will drive well and suit your needs rather than delivering big peak power but becoming undriveable in the process. Of course, if you happen to be building a car where big power is your need, then why not aim high and punch through the 1000hp barrier? It’s the sensible thing to do.
If we told you that Ole Ivar Seem, the owner of this E36, comes from Norway you probably wouldn’t be surprised because it would seem that Scandinavians have a predisposition for building stupidly powerful cars. And, unlike those of us having to find time during evenings and weekends to work on our cars due to our 9-5s taking up the vast majority of our time, Ole works on offshore oil platforms, which means he works hard but then has plenty of time to play hard when he’s back on dry land. And play hard he does.
Funnily enough Ole says that while he’d always liked BMWs he didn’t become properly interested in them until about 2003, when Vidar Strand from V.S Motor hit 1000hp with his E34 M5. That got his attention and got him thinking about the possibilities of what could be achieved with a BMW. And judging by one of his previous projects – a 426hp Sierra Cosworth, which was featured in our ex-sister title Performance Ford back in 2003 – it was clear that unless big power could be achieved Ole wasn’t interested. Of course, his first #BMW project was never going to make anywhere near that power output, being as it was an ’1986 E30 320i, but then again Ole only bought it for a bit of winter fun and threw a few mods at it. However, it started the sequence of events that mean we’re now standing here today with his 1000hp E36 M3.
With the Cosworth sold and a lump sum burning a hole in his pocket, Ole cast his car-catching net to see what he could snag. That’s when he came across this M3. “I found the car on a BMW forum here in Norway,” he explains. “It was a virtually completed street build with lots of good parts but that looked completely stock on the outside. Initially the plan was really to run with the parts that were on it but a thought crossed my mind about building a car for Gatebil Extreme [Gatebil’s own time attack and racing series]. After driving the car for a bit back in summer 2008, I got problems with water in the oil, leaking between the pyramid rings and water channels. So the real story of the car and engine you see today started when I picked up the phone to Vidar at V.S Motor.
“The motor building began with solving the problem of water in the oil. Vidar had a separate patent which, in principle, removes the head gasket and uses rings in a special metal. Vidar also fitted new custom cams from V.S Motor, new custom V.S Motor pistons, uprated Pauter con rods built to V.S Motor’s specifications, stainless steel valves, tighter valve springs and he did a general update of the whole engine. He then put it on the dyno bench at V.S to get it mapped properly. With it running perfectly we went for a power run and it made 772hp and 723lb ft of torque at 1.3bar, but tremendous back pressure on the exhaust side prevented any more power. The problem was an exhaust manifold that was not quite optimal and a Turbonetics turbo that was completely the wrong setup. I drove the rest of the summer and next spring running this setup but I was bothered by the fact that it did not deliver optimally when I knew I could get much more from the engine.
“After a few more conversations with Vidar we agreed that he should build a new manifold and a new turbo, then test it. The engine was ready in April 2011. This tested Vidar’s patience to the limit as it’s really cramped around the engine for building a manifold. You really need a lot of space. I think someone would have to pay him a lot of money to do this again!” laughs Ole. “On test day the engine really stood up to our demands, and on E85 fuel it delivered 1039hp and 817lb ft of torque at 2.1bar. You can say we were delighted with it.” And who wouldn’t be with over 1000hp on tap? But Ole and Vidar weren’t finished with the engine just yet. “In summer of last year we found out that we were going to start with new fuel as E85 was phased out from petrol stations in Norway, so we chose to use the Ignite E98 race ethanol fuel that Vidar sells.
We counted on a power increase so in July 2015, before going to the E30 meet in Rudskogen. I went with Vidar to Jonus Racing to run the car on the dyno. After roughly four to five hours of fine-tuning, the numbers that it put down really made our eyes pop! We got 1040whp and 855lb ft wheel torque which, when converted to power at the crank, becomes 1196hp and 959lb ft at 2.2bar. It goes without saying that were extremely pleased with this outcome,” smiles Ole.
We would be too. That’s an absolutely monstrous amount of power, especially considering he’s still running the 3.0-litre S50. That works out at 399hp per litre; that’s like the E39 M5, with its 4.9-litre V8, making all of its power from a 1.0-litre engine, which is a bit mental when you break it down like that. As far as engine spec is concerned, we simply haven’t got the space to go through all of it here, just take a look at the spec list and you’ll see it’s exactly as long as you would expect it to be on a powerful engine like this. Highlights include the Precision billet 7675 turbo – such a key part of this incredible build, adjustable cam pulleys, a Tial 60mm wastegate, 4.5” downpipe, 3.5” Edgeperformance exhaust, ARP bolts, a 26-row oil cooler, custom header tank, Griffin radiator, custom 6” thick intercooler, 580lph Aeromotive lift pump, twin A1000 fuel pumps, and a set of six absolutely ridiculous 1699cc flow matched fuel injectors. All of which is really just scratching the surface. It’s as heavy-duty a build as you can imagine.
You can’t just make a 1000hp engine, stuff it into an E36 M3 and hope for the best because things would go south in a big way almost immediately. You need to put in just as much work on the transmission and chassis fronts to make sure everything works in perfect harmony. There’s no messing about when it comes to the gearbox on this car, with Ole fitting a Sellholm MPG sequential ’box made specifically for this car and combined with a Tilton 7.25” threeplate, 26 spline rally clutch and Alcon hydraulic release bearing. A 3” chromoly propshaft rated to 1500hp delivers all that turbocharged power to a modified 210 diff from a 3.2 M3 sitting on reinforced mounts, and a pair of 38mm driveshafts.
As for the suspension, well, we’ll let Ole explain: “Everything under the car is solid mounted or uses aluminium uni ball components. I run custom road coilovers from Sellholm Tuning made specifically for the weight of the car and supporting chassis mods. These include: Sellholm Tuning front and rear fully adjustable blade anti-roll bars; custom front suspension turrets and custom adjustable top mounts; Turner Motorsport aluminium bushes and rear lower control arms; and PeeBee Motorsport adjustable rear upper control arms.
“When it came to choosing the parts, Vidar knew exactly what was required, having been involved in so many builds, not to mention his racing experience. I trust him 100% and he is the man to talk to when one is stuck with ideas or problems, although these phone calls can be expensive. That’s how I ended up with the sequential gearbox!” With over 1000hp on tap, you need some seriously big brakes to haul the E36 down from the sort of speed it can achieve, and Ole hasn’t cut any corners here. Up front, eight piston K-Sport calipers have been fitted, clamping 355mm discs, while at the rear sit six-pot calipers with 330mm discs and EBC’s BlueStuff track day pads have been fitted all-round. Wheel choice was guided by necessity rather than aesthetics, as you’d expect on a build like this. “The choice of rims came after lots of searching on forums and chatting with acquaintances in the racing world. To make most of the rubber on the ground, without extending the arches or anything like that, the wheels had to be lightweight, withstand a lot punishment and with widths matching the chassis. I chose the Apex EC-7 as there were really no other wheels that matched the car. They fitted well with the look that I had in mind for the car.”
The tough, lightweight wheels measure 9x18” up front and 9.5x18” at the rear and are mounted on the car via a set of NMS Racing 75mm studs.
Just by glancing at the outside of this E36 you’d really be hard pressed to tell what’s going on beneath the surface as Ole has kept everything looking extremely stock. “My goal has always been to retain the original lines that I like so much,” he says. “Generally original but sassy, a look with a little more muscle. There’s a fully removable carbon bonnet, a carbon sunroof blank and the only change to the body itself is that the rear wheel arches have been rolled.”
Of course, the interior is another matter entirely and there was only ever going to be one direction to take it in. “The choice was easy,” says Ole. “It should be for racing! It had to be as light as possible and, ideally, with parts that no one else in Norway or Europe had tried before. Plenty of time went into building the roll-cage, which was done by a colleague and myself with Vidar providing all the technical information. It is made from about 80 metres of chromoly 4130 tubes and has been built down towards the chassis to really get it rigid, to the suspension turrets, to the diff and many other reinforcements against the chassis, which you can’t see in the pictures. In reality it is a tubular frame inside the car.”
Beyond that there’s a QSP steering wheel mounted on a Sparco Group N quick-release steering boss, Cobra Suzuka seats with six-point harnesses and a Racepak UDX data logger dash with auxiliary Autometer gauges. To keep things as light as possible, the car has been fitted with ACM carbon fibre doorcards and even a carbon firewall, carbon dash and carbon centre console while the boot is home to fuel system, with a 60-litre Aeromotive aluminium fuel cell and aluminium swirl pot.
After a hell of a lot of planning and almost seven years of work, it’s unsurprising that the end result was so damn spectacular.
What is surprising, though, is that Ole sold the car not long ago but, he says, it’s gone to a man who really knows what he’s doing so it’s in good hands and will be used as intended by its new owner.
So, what’s next for Ole? Time to give up the modifying game and relax with pipe and slippers watching gardening programmes? In a word, no. “I already have plans going around in my brain but one thing is for sure, it gets wilder!” he exclaims. “This car will probably take a few years to finish. And I have a problem: I’m never satisfied until I have spent a lot of time on everything from planning to execution, so those who wait will see. The rest is a huge secret,” he adds with a grin. We’re instantly as excited as he is. Judging by his track record, it’s going to be something special.
Interior is slathered in sexy carbon panels.
Apex EC-7 wheels were chosen as they’re light and tough; massive eight-pot K-Sport calipers sit up front with six-pots at the rear.
That’s what you need for 1000hp. S50B30 has been fully built and features massive Precision 7675 turbo.

This unassuming #BMW E28 hides 655whp of pure turbocharged fury beneath its classic styling. With massive turbocharged power wrapped up in unassuming E28 looks, this 5 Series is one deadly road warrior. Words: Elizabeth de Latour. Photos: Hjalmar van Hoek.
Turbo E28s are like buses: you wait ages for one to come along and then three awesome feature cars turn up in the same year. But as fans of all things E28 (and turbocharged) we’re most definitely not complaining. It probably won’t surprise you to learn that this E28 hails from Sweden, as there seems to be something in the Scandinavian water that makes BMW fans shut themselves away over the long winters and emerge blinking into the spring sunshine having crafted some form of forced induction beast over the preceding months. Works for us.
By day, Gunay Selmanovski is busy repairing Volvos but by night, and possibly also on weekends, he can be found thundering around the Swedish countryside in this beast of an E28. It’s his first project on this scale, his previous cars having all been modified but none beyond some lowering springs, bigger wheels and an exhaust, so he’s really done an awesome job.
He has owned the car for ten years now, purchasing it as a “poor student” (his words) at the tender age of 21. “The performance for the price was unbeatable,” he says, “and it was a great combination of handling, power, convenience, luxury and comfort – it really is the ultimate driving machine.” Purchased with no plans other than simply enjoying the driving and ownership experience, all that changed when Gunay stumbled upon an M106. That makes this the second car in this issue running that engine (the other is 666CSi ) and the third this year – clearly, it’s the current go-to choice for a big-power straight-six.
Gunay has been working on the car since 2005, starting out in a rented garage before it was moved to his dad’s garage in 2010, and this E28 has come a long way from the rusty and rather sorry state that he purchased it in all those years ago.
The M106 in particular has undergone quite a transformation, with one year being spent on it alone, and while it is an excellent starting point for a turbo project, thanks to its force-induced foundations, serious upgrades are required if you’re hunting for serious power. The bottom end has remained stock, as have the internals, and Gunay has focussed all his attention on the head, porting it before adding a copper gasket with an ARP stud kit, fitting an M7 300/300 camshaft, HD rocker arms and Stage 2 valve springs. For the turbo, Gunay has chosen the beefy #Precision 6265, more than enough to produce the kind of power figures he was gunning for, which has been fitted with a 60mm wastegate and 2.5” screamer pipe, along with a 50mm blow-off valve. A 600x300x76mm intercooler sits up front, feeding air into a rebuilt M5 S38 plenum, and is joined by an uprated Griffin aluminium radiator with a 385mm Spal electric fan and a 30-line oil cooler. On the fuel front, a pair of Bosch 044 pumps feed 1260cc Precision injectors. Gunay’s hard work under the bonnet means a spectacular 655whp and 629lb ft of torque at the wheels, monstrous figures considering how light the E28 is. The transmission has been seriously beefed-up to cope with all that grunt, with the old five-speed gearbox having been replaced with a rebuilt #Getrag-420 G gearbox taken from an E46 M3 and mated to a Sachs six-puck sintered clutch and 765 pressure plate. The propshaft is from an E34 540, rebuilt with a bigger joint and 94mm CV joint, and it’s connected to a refurbished 210 40% locking LSD in a reinforced housing on a reinforced E28 M5 diff mount with stronger driveshafts.
Aesthetically, Gunay’s E28 is most pleasing – there’s just something so right about the way it sits and looks. There’s a purpose and muscularity to its stance and appearance that we like. When he bought it, the car was wearing the BMW side skirts but was missing the front and rear bumper additions, so they’ve now been added. So too has a rear spoiler and, while most people are busy getting rid of their chrome trim, Gunay has not only kept the shiny window surrounds but has also added an E12-style front grille chrome trim. It all combines to give the car a classic, period look.
On the suspension front, Gunay wanted a set of D2 Street coilovers but at the time there was nothing available off-the-shelf, so he bought an E34 set and modified the dampers to fit the E28. His ride-height is perfect, as is his choice of wheels in the shape of a set of #OZ-Futuras . “I always wanted these wheels,” he says, “and had them in 17”. However, when I came across a set of refurbished 18s I bought them straight away.” Measuring 9”-wide up front and 10” at the rear, they fill the E28’s arches perfectly, though considering how much power he’s running, Gunay has not been afraid to go for some stretch, with 215 and 225 rear tyres. Underneath the car has been fully polybushed while thicker E28 M5 antiroll bars have also been fitted, front and rear. The uprated brakes have been sourced from within the BMW family: an E32 750 brake master cylinder has been fitted with E32 750 four-piston front calipers and 324mm discs, while at the back are a pair of E34 540i brakes. Braided steel hoses have been fitted all-round.
Finally, for the interior, Gunay has kept things simple and original with minium modifications. The Pearl beige interior with its Sport seats has been untouched, there’s a period refurbished M Tech 1 steering wheel, E28 M5 door sills, an Alpina dashboard, an illuminated six-speed M gear knob and the finishing touch is a trio of gauges.
What Gunay has built is a magnificent sleeper. There really is nothing here to give the game away, beyond the noise perhaps, and he relishes showing modern performance machinery a clean pair of heels, much to their owners’ consternation. “I have embarrassed an E60 M5, a Mercedes E55 AMG and an E90 M3 on the motorway, and the look on the owner’s faces was priceless,” he grins. It’s been a long build for this E28 but Gunay’s skills as a mechanic have shone through and he’s over the moon with the machine he’s created. Beyond the performance, unsurprisingly his favourite part of the whole, it’s an incredibly clean E28 and that in itself is something of a rarity and definitely worth celebrating as the vast majority of these have now succumb to terminal tin worm that very few owners, other than enthusiasts, will be willing to spend money removing. “When I took the car to its first show everyone said they had never seen an E28 in that condition and with such a clean engine,” says Gunay. Most importantly, this car is now finished: everything that needed to be done has been done and now comes the very serious task of getting out there and enjoying the hell out of it – something else that Gunay is extremely good at.
