Jacek's M3: In Good Hands

Indoor karting lay the foundation, then construction gigs throughout college gave Jacek Kozubek the chance to scrape enough money together to buy himself a two-stroke kart. He flipped a few cars on the side, too. It seemed there was never enough money to fund his new habit back then.

Frustrated though he might’ve been, he kept going with his entrepreneurial pursuits, and these put him in touch with more experienced racers who could make his transition into racing full-sized cars even easier.

Once out of school and making a little more, he started scanning his surroundings for the right track car. It was R-Crew Inc. who helped guide Jacek through this often frustrating process, and after an introductory period with a healthy DC2 Integra, Jacek followed R-Crew’s advice and picked up two of the more popular platforms in today’s track scene.

After the end of this trial period, he decided he preferred his E46 M3 to his S2000. “The S was great, but I felt a little disappointed with the straightline performance. It was better than the BMW stock-for-stock, but when I got to drive Don’s M3, I could see how good an M3 could be with the right modifications.”

Wisely for a man buried in work and family obligations, Jacek handed the car over to R-Crew for modification and maintenance. The first order of business was the typical set of wheels, brakes, and coilovers, though he saw no sense in half-assing it. Fancy footwork it would be, and after adding AP Racing 5000R brakes, JRZ 11-series coilovers, and a set of 18x10” Volk TE37s, the M3 was no longer the plush and porky thing it was in stock trim. It was now a riveting street-track car, but far from perfect.

There was still some sponginess to the car, as well as a notable lack of traction in hairpins. R-Crew replaced the poly bushings with heim joints, then fitted a 1.5-way OS Giken diff to minimize inner tire fire. The resulting surefootedness provided the platform upon which Jacek could add some aero grip; a Bimmerworld splitter and full-carbon wing only helped the car—there were no slow-speed shortcomings from the wings.

Since Jacek handed the car to R-Crew for transportation to and from the track, he didn’t see any reason for keeping the car even remotely streetable—it would be a full-on track build. Out went the interior and in went a Tony Colicchio cage. Additional weight shedders included a set of lexan panels to replace the rear quarter glass, Bimmerworld fiberglass doors, and R-Crew’s full exhaust. After the dieting measures, the M3 weighed in at a respectable 2,850 pounds with driver.

That full exhaust was the only modification made to the motor, and that simple recipe made it into a dependable lump. The S54 sometimes gets a bad rap, but with the right sort of maintenance, it’s a workhorse—Jacek’s record is testament to that.

In four years, he’s run roughly thirty-five faultless track days with this particular engine. These aren’t standard track days either; Jacek typically runs multiple run groups on the same day. Sometimes, he’ll drive two consecutive twenty-minute sessions, and after missing the first few laps of the third session to fill up at the pump, he’ll finish out was is nearly a sixty-minute sprint.

With all the big boxes ticked, there’s not much more that the car needs. For Jacek, a driver who prioritizes seat time, he’s absolutely fine with that. However, the car could go from welterweight to lightweight with the two big jobs on the horizon. After fitting a carbon dash, the guys at R-Crew plan to pull the entire wiring harness and install an AiM PDM32: a solid state power distribution module that allows them to pull the fusebox and all relays. With some luck, these two mods might shed another two-hundred pounds.

Hoosier A7s have been his choice for a long time now.

Over the last fifteen years, from scrounging cents to run karts to spending big dollars at the track, Jacek’s enjoyed good luck with his hobby. When money was tight, he focused on getting the most track time in the way that was feasible: through karting. Now, after making some money, he’s learned to spend it wisely. With all the newfound freedom it’s brought, he’s come to value his time more, and rather than spend it wrenching, he’ll happily hire those who do this stuff better than any hobbyist would.

By leaving the car to R-Crew, he’s been able to ensure his time at the track is spent as efficiently as possible. The car runs without hiccup, it’s set up to suit his driving preferences, and if ever he’s got a question about a change he could make, he has an experienced crew to consult. He’s gone from frugal to experience-focused. If an ambitious driver has the means to leave maintenance and transportation to the professionals, why not? It’s always better to be in the best hands possible.

The money’s been spent, and now all that has to be done is drive, really—drive it into the ground. “I use my iPhones until they’re so cracked I have to replace ‘em, and I’ll drive this car until I put it into a wall.”

It’s amazing how he’s been on the money the whole time.

Edson's E46: Quarter-Million and Counting

He found his feet in the world of autocross, but a little bit of mockery from his track addict buddies made Edson Burgos ditch cone course carving and dive headfirst into road racing.

Edson remembers the moment fondly. “I got a ride around Sonoma in a friend’s Civic Si. Yeah — that’s when my life started to go downhill.”

The S2000 that had brought him so much pleasure in autocross was a sensational first track toy, but Edson, being a bigger fella, found the Honda to be less than ideal for daily duty. Only one parking space at the time mandated he have dual-purpose machine, so he sold the S2000 and picked up a mint E46 M3 ZCP. The performance out of the box wasn’t bad, but Edson knew he wanted to go all in modifying his street-track car., and this one, as he put it, “was just too pretty to chop up.”

Wisely, he made a bit of money selling that gem and decided that he’d look for an example a little rough ‘round the edges so that when it came time to strip and slice, he could do it with a clean conscience.

One well-worn example popped up on his radar. The odometer had just ticked past the quarter-million mark, but the annoyingly low price of five racks was fair and Edson swooped it up in thirty-six hours.

The previous owner had taken some pretty innovative approaches to quieting the creaks and rattles present in a 250,000-mile M3, including expanding foam. The paint was patinaed harshly, so even at twenty-feet it showed its age. However, the motor sounded healthy, and that was enough motivation to begin replacing every OEM bolt, nut, and bushing on the ol’ girl.

Along with the underbody overhaul, Edson dropped nearly twice the price of the car on every E46 M3 owner’s big gripe: rod bearings, VANOS, and subframe reinforcement. These are a must-fix on most of M3s of this generation, though the later cars aren’t cursed with the same rod bearings as the earlier cars. However, after dealing with these three, the E46 is a workhorse willing and able to take the abuse.

He wanted the weight of the car to take a dive, so he tossed the rear carpet and seats, put an Autopower bolt-in half-cage in their place, and a Sparco Evo XL in the place of the plush factory driver’s seat. There’s no sense in holding onto heft when the sunroof-equipped car is already meant to be a track toy, and since he and his wife had a reliable daily at this point, he could make this car as extreme as necessary. Accepting that approach made it easier to drop another couple thousand on a CSL carbon trunk.

Not that he wanted to go for a full-aero build with big power and composite panels. This build was meant to remain simple and reliable, so only the necessary performance modifications were made—and made in one fell swoop. There aren’t many, but the few he did make are quality. JRZ RS Pros, DO88 radiator and oil cooler, and a Ground Control front swaybar.

Being that the motor is as well-used as it is, Edson thought it wise keep all power modifications to a minimum. To get a reliable 300 wheel from the S54, all it took was Build Journal B-Spec tune and Myers Competition’s header and single-exit exhaust. Say what you will about the last atmospheric M-grade straight-six, but with a few mods for power and reliability, it is a glutton for punishment, even at a quarter-million miles.

With these goodies, the M3 was sorted, dependable, dailiable, and fun. That is, until he tried braking past the three-marker at the Andretti Hairpin. Laguna’s known to be hard on brakes, and Edson learned this the hard way when his stock brakes failed. He managed to keep it out of the wall, but this 120-mph scare drove him to buy some big brakes the second he got home that night.

Up front, he did not skimp. AP 5000Rs stuffed with Winmax W5s are perhaps some the best big-brake combinations for the car. At the rear, he opted for a set of the old school Porsche 996 Brembo “Big Reds” and fitted some of Hawk’s DTC-30 pads for a stable rear under deceleration.

Since Edson had his hands full adapting to the torquier motor, he appreciated the M3’s composed, predictable behavior under braking. “i had to be a lot more careful with the power; it was too easy to overdrive. Everything else was easier. Six years in the S2000 taught me a lot. I wouldn’t be as comfortable in the E46 if it weren’t for my previous car.”

He’s put in some impressive times in the meantime. He can lap Sonoma in the 1:49s and Laguna Seca in the 1:40s. For a 3,300-pound car (with driver and fuel) with stock bushings and no aero, that’s pretty dang quick.

“It took me a year to adjust to the platform, but I’m super comfy now. Without all that time in the S2000, I wouldn’t have adapted as quickly, but I’m here. That car was nervous—not that this one isn’t, but I don’t think I’d be able to catch the faster slides if I didn’t spend so much time spinning out in an S2000.”

Dustin's Supercharged M3: A Lesson in Applied Economics

He wasn’t intimidated at the prospect of buying and tracking an E46 M3, but Dustin Furseth felt some pressure to build one in a way that would allow him to balance his checkbook. That’s a normal concern, but with a baby on the way, he couldn’t afford to get in over his head.

But with the car’s reputation and its strong aftermarket support, as well as his knack for finding a little sponsorship here and there, he turned this basic road car into a approachable, reassuring, and still-somehow-comfortable track toy in only a few years. It also makes 500 and change.

For the first few seasons of track work, Dustin was known to leave a child’s car seat by his parking spot at the track; sometimes he’d drop his boy off at daycare before putting in four or five sessions. He wanted to make the best use of his time, clearly. For that reason, after adding MCS one-ways and Ground Control arms, he hired a coach for several weekends and refined his driving style.

His approach was an intelligent one. After one impressed coach suggested he try a more competitive form of motorsport. Dustin finally had the confidence to step up, and after a friend recommended Global Time Attack, Dustin entered his modest M3 in Street Class.

In time attack, he found a sparring partner in Karl Taht, whose S2000 was, on average, a hair faster at technical tracks. Dustin’s M3 usually had the upper hand at faster tracks, but the two were trading tenths regularly and pushed to get the most from themselves and their cars.

Not interested in mega power or hiring someone to fabricate piping, Dustin picked this easily-installed kit.

When Karl decided to turbocharge his F20C, he inadvertently dropped the gauntlet. Dustin responded by modifying his S54 with a trick head and some big Shrick cams, but it was no longer a reliable motor. After a year and a half, it popped.

When it came time to rebuild, he considered another attempt at a highly-strung engine, or, as his friend had, he could try forced induction. A little research convinced him he could bring power up by 200 and still save some money over another strung-out S54 if he could bring himself to boost a stock engine.

With an ESS G540 supercharger kit, he had to upgrade the clutch to a Clutchmasters FX725, beef up the cooling system with a Mishimoto rad and oil cooler, and add a little ducting to ensure air flows through the right channels and isn’t recirculated at the backside of the radiator.

Now, the boosted S54 is a real powerhouse—legitimately GT3 RS-strong, distinctive, and resilient. Even though the blower makes a peak of 515 at the wheels, it doesn’t change the delivery or the driving experience that much from when the engine made 300 at the wheels.

The blower doesn’t really change the shape of the curve, it just elevates the curve a few hash marks higher on the dyno chart. It feels intuitive. What is most different about the new powerplant is that there is appreciable torque where there once was none. It’s not peakier than the engine was originally, it feels like there are a few more cubes available.

An RS Future splitter helps encourage a neutral balance at speed.

The power was easily transferred into propulsion before the blower, but the new grunt alters the way Dustin has to depress the pedal. With eight pounds of boost at his disposal, he can spin the wheels for a hundred feet after a second-gear chicane if he’s out to impress a passenger.

However, the car’s grip and poise means it still takes a lot of provocation to do so. In other words, car can still be leaned on mid-corner and generate strong drive off the corner, provided he’s not using the wrong gear.

There is the matter of gear selection. The hairpins which rewarded a second-gear exit now have to be taken in third; the power delays throttle application in sections where the car is traction-limited. Not everyone considers it, but if a bump in power means it takes longer to deploy it, is it worth the addition?

Going from a 275-square setup to widening the rears with 295s has made the car border on high-speed understeer.

The answer is yes. Even when it does light up the driven wheels, the rear remains planted. Maybe that’s the APR GT250 wing imparting some stability, but even in slow hairpins, the factory LSD does a stellar job.

This staggered setup promotes a little understeer, but it’s a minimal amount of push and it’s really only noticeable in faster corners if he’s hasty putting the power down. Yes, there is an iron lump up front, but the big motor doesn’t make itself noticeable unless the throttle’s stabbed mid-corner. Line things up after a committed flick into the corner, then power out with encouraging neutrality.

For all this fun, he’s had to pay another fee on top of the supercharger’s purchase price. The oil breather, after enduring high revs, would mist onto the belts, which would underdrive the water pump and overheat the engine. After a quick fix involving a rag and some hair ties, the engine hasn’t given him any other headaches.

“The brakes have been a great addition. When I put something on my car that I believe in, I try to explain it to people as best as I can.”

The added strain on the brakes from a middleweight with serious power made it necessary to go for a big brake kit. However, he wasn’t keen on spending the money needed to buy the AP Racing kit he had his eyes on, so he found an affordable alternative.

Underneath his Apex VS-5RS, he opted for PB brakes front and rear. The fronts use eight-piston calipers and 380mm rotors, and the rears use six-piston calipers with 356mm rotors. Complete with the motorsport-grade bobbins, knockback springs, and floating rotors, the kit has proven itself track-worthy. The calipers are finished in a subtle shade of silver that blends in beautifully, too.

By milling down used pads bought from endurance teams, he’s saved himself money and time. The rotors rarely need replacing, the pads last thirty-odd sessions, and even with the old Mk20 ABS, the car inspired a lot of confidence in the braking zones. Higher speeds and ~3,000 pounds put some real strain on the binders, but the PBs have handled that well.

And despite all that focus and performance, it’s still very much the sleek machine Dustin bought seven years ago. Yes, the wing and RSFuture splitter, and N15 vents leave nobody doubting its role as a track toy, but Dustin’s insistence on leather-wrapped Recaro Pole Position NGs and the retention of most of the interior prove he’s after a little more than speed alone.

It doesn’t come as a surprise that Dustin is an architect—he has to weigh aesthetics and functionality as part of his job. The soft shape of the car, the silver and carbon-black scheme, and the simple execution make it a stunner that you can sit and drink in for minutes, even if it doesn’t call your name from across the paddock.

In other words, it’s a complete car—and not many cars built on a careful budget are truly complete. Dustin did his homework, though, and even with a full plate, he got where he wanted to be quickly. Stay in school, kids.

Elie's E46 M3: Not Too Much, Not Too Little

For Elie Mansour, the E46 M3 is one of the most driver-friendly machines he’s ever driven—and he’s driven just about every trackday staple.

In 2003, Elie started tracking in the States with a fourth-generation Camaro, but to him, a man who grew up watching smaller vehicles hillclimbing in his native Lebanon, the Camaro seemed somewhat cumbersome.

“Everybody was driving the Subarus and Evos, S2000s, and a handful of E36s then.” His natural affinity for the capable E36 led him to buying one of his own, but its lack of power and regular maintenance left him wanting a little more. “For about six months, I considered swapping an S54 into my car, then my friend let me drive his E46 M3, and it just felt so much sturdier. When I factored in all the associated costs of swapping the new motor into the old car, I realized that I’d be better off buying an E46.”

Wisely, he avoided building one from the ground up. The Imola Red ‘02 he procured already had been partially stripped and fitted with an Autopower cage, big Brembo GT 355 brakes with Cobalt bads, and a set of Ground Control coilovers. As a precaution, he removed some of the failure points. Simple and effective, this platform needed nothing more than a set of solid mounts and bushings before Elie logged fifty events his first year with it.

Building Upon a Brilliant Foundation

Despite the running costs and the growing appetite for better parts, this busy first year didn’t tax him too much. The reliability of the car was astounding; changing the pads every dozen days and the oil about half as often. Then there was the ease of operation. “The E46 is one of the most driver-friendly cars I’ve ever owned; it has great headroom, great visibility, ergonomics, and it’s easier to drive than any other car at this performance level.”

Relatively simple operation, a moderate amount of weight, more that adequate power, a reasonably comfortably size, and—assuming one buys a good example—a manageable price. In so many ways, the E46 M3 is the ultimate Goldilocks car: not too much, but not too little.

Perhaps all this versatility came with one setback: weight. Being reasonably large and somewhat plush, the weight became more and more of an obvious hindrance the harder he pushed. Removing the sound deadening and carpet, then replacing the standard Getrag six-speed with a ZF five-speed allowed him to bring the weight down to 2,825 pounds.

It only followed that he would sharpen the chassis with whatever means readily available. After adding Ground Control swaybars, he sought out a set of revalved shocks to suit the lightened chassis. A knowledgeable friend practically gave him a set of used Motons that’d been collecting dust in a shop, but further inspection revealed the fronts were damaged beyond repair. At that stage, his friend admitted that he used JRZ parts to rebuild the other Motons he’d been given.

They shared a laugh, then took the expedient solution: using a set of JRZ RS Pro two-ways to replace the faulty fronts. With a little tweaking, he found the two brands to complement each other. “The two work well together, and the JRZs are so much easier to service than the Motons. It’s an unusual mix, but it was a no-brainer for us.”

With the footwork seriously improved, the slapped on a set of Pirelli DH crubs and began impressing the bystanders. His aggressive, tail-out driving style honed through years of messing around on gravel roads had to be tamed somewhat to go faster, but at least he was never limited by a lack of car control.

With the car handling well, he turned his attention to the powerplant. The S54 is, with the right sort of maintenance, a fairly robust motor that might get a little too much negative press. That said, it needs some uncorking before its sonorous scream can be fully appreciated. Along with an AFe intake, an eBay header, a Bimmerworld exhaust, and a BSpec tune, the motor made a healthy 323 horsepower at the rear wheels.

While the motor is stout, tracking can elevate temperatures to a worrying level. The iron block’s chances of overheating diminished greatly after he added a Bimmerworld motorsports thermostat and oil diverter, a CSF radiator, and a custom built electric fan, he’s been able to keep the iron block cool, even on sweltering summer days. “Don’t forget: a high viscosity oil is a must. During the summer months, I change the oil—usually 10W60—every three or four track days.”

With the motor fortified and the suspension sorted, the car was as dependable as any thoroughly thrashed track tool, really, and Elie prioritized seat time over all. Nearing his hundredth track day, he’d pushed the M3 to about as far as anyone was capable, and the few shortcomings in the car started to make themselves apparent.

Ready for a new challenge and a little more stability at speed, he decided to call on Trackspec Motorsports, who were then sponsoring him, and ask for a contribution in the form of a modest aero package.

The takeaway here was that he hadn’t simply reached for the biggest wing prematurely. He and Trackspeck went through a series of different combinations before settling on the G-Stream wing and their tegrid-constructed splitter, which was chosen for its durability. The result was, well, just watch the footage below to see the car in action:

Even Monkeys Fall From Trees

And then, perhaps as some sort of divine/cosmic payback for 180,000 miles of faultless operation, the motor coughed its last breath. He tucked the car away to the back corner of his garage and helped a few friends build their E46s with his two decades of knowledge,

It still sits in the corner, but another S54—again built for reliability—is almost finished. When the motor is implanted in its new home, he’ll address the two remaining flaws he’s noticed. “The OEM LSD acts like an open differential now; trying to get any traction out of Buttonwillow’s Turn 2 is futile.”

Besides that, it needs a few more safety modifications to move into the next realm of competition: NASA ST4. Trackspec Motorsports will likely prototype the cage, and along with a fire system, full window nets, and a restrictor to meet class restrictions, he should be ready for wheel-to-wheel. He’s got the car control and the courage, so the transition shouldn’t be too difficult.

Peter Phung's Widebody M3: Wide and Wonderful

Search YouTube for Hans Stuck Jr. romping around the Nurburgring in his M3 GTR. The widebody, V8-swapped E46 in that famous clip was as gorgeous as it was quick. Peter Phung hadn’t actually seen that video until I mentioned it to him a few days ago, but several years back, he’d found another image of that car that encouraged him to try building his own version of what some see as the ultimate E46.

Immediately after picking up the car, complete with moonroof and a six-speed, he handed it off to someone else like a negligent father. He wanted to attach the DTM Fiberwerkz widebody kit sitting in the corner of his garage, and so he entrusted one shop he knew little about with the task.

It became a pretty significant job since black paint wasn’t exactly doing it for him—mainly because he’d already pictured the ultimate iteration of this car as one with a white base. This M3 was meant to be an homage to the original GTR, which is doused in white with the M-tricolor striping. He handed it off to the professionals and waited eagerly for a pretty car to come back to him.

Peter posing beside his sister Florenza with the car wearing a simpler livery.

Once back in his hands, he was mostly impressed. The paint looked great, but the bodywork was terrible; he noticed cracked fenders and excessive fiberglass reinforcement pretty soon after. Oh well—it was meant to be a track weapon, so he moved on and started addressing the shortcomings of the stock suspension. The first round of mods consisted of Turner swaybars, and TC Klein coilovers, Brembo big brakes, and a set of Bimmerworld brake ducts.

Besides the stripped cabin and the lightweight Recaro buckets, the diet consisted of a few things: aluminum door panels, two fixed Recaros, a DTM Fiberwerkz hood, an RKP carbon roof, a removed rear deck.

Interestingly, the extra tire and width came at a serious cost to any track-dedicated car. Though made from fiberglass, the bodykit added another 200 pounds to the tally. Even after gutting the interior and taking other weight saving measures, the car still weighs in at a slightly doughy 3,100 pounds.

TC Design installed a gorgeous half-cage and made the necessary subframe reinforcement problems, then Auto Logic replaced the rod bearings with WPC coated rod bearings and refreshed the VANOS with the Beisan kit. After that, Auto Logic cleaned the combustion chamber, performed a five-angle valve job and administered the Epic tune. If the car had been given to the wrong people initially, he made sure that everyone else who touched his dream M3 were top-tier.

The one persistent gremlin that plagued them, an overheating issue, was traced to the A/C condenser. Once they chucked that in the trash, the car ran cool in the scorching summer temperatures. Powerful, tractable, and reliable—the S54 with a little work is something special.

Along with a custom fitted Borla cat-back and long tube headers, the naturally aspirated package pumps out roughly 360 horsepower—more than enough power for a heftier E46 M3.

Peter’s thinking was that if the extra weight offset its above-average power output, the wider footprint would have to compensate. To make the most from this, he deicided that he needed a better suspension system, upgraded to a full 2 way adjustable MCS pro suspension, added a set of spacers, and fitted Titan 7 wheels measuring 18 x 10.5”. Peter then added camber plates, a stiffer front sway bar and rear traction arms from Ground Control. Even with the stock differential, the combination of massive tires and a soft rear makes the BMW sticky, predictable, and easy to lean on.

There’s a constant through this build, and that’s that his entrusting the car with enough gifted people to make up for the few bad apples who got their greasy mitts on it way back when. Once he had the gifted guys at 101 Paintworks fix the widebody, he was finally satisfied with this ambitious build. Finally, the showpiece part, the amazing widebody, the thing that distinguishes this from all the other E46s, was fitted like it was supposed to be.

“It handles well, but I’d say it looks better than it performed than it did during the first phase. I did want it to look good—so at least I accomplished that goal,” he said with a chuckle. After going though five years of changes, upgrading to better performance parts and more than doubling his original budget, the car performs as good as it looks.
