Walk the line
Strapping a supercharged to the already potent Z4 M makes for an exceptional performance machine.

Tuning a car is often a fraught process. There’s the stress that comes from buying new products, not knowing if they’ll work until they’re on the car, despite your hours of research. There’s the possibility that the workshop you’ve chosen will do bad work or rip you off. And, of course, there’s the likelihood that fitting upgrades will simply expose weaknesses in other parts of the car you weren’t aware of, forcing you to spend money you hadn’t planned to.
Melbourne, Australia’s Kris Hooper knew about all those potential pitfalls when he chose his 2006 Z4 M Coupé. A tearaway in his younger days, he’d managed to destroy one car and blow two engines in another before getting a 1998 Subaru WRX sedan as his first proper performance car. However, his experience making mild mods to that, coupled with his otherwise methodical thought processes and focus on research, meant when he decided on something European to change things up, he wasn’t going to approach the project with anything other than highly considered plans to ensure he avoided many of those common tuning errors.
“Magazines and forums have taught me how easy it can be to perform a modification only to find you are not happy with the result, to not get enough bang-for-your-buck, or to find further down the track that it is incompatible with something else you have planned.” All this is why, before he even began, Kris had a pretty clear idea as to what he wanted and how to achieve it. The Z4 M base was already a great start – powerful, with great street handling and braking, and looks that Kris fell in love with well before the test-drive. But his desire for a true all-rounder that combined ability on the street with track prowess meant things had to be planned well in advance, particularly as, being such a rare car outside of America, parts were not exactly in huge supply. “Most of the parts I’ve used have come from the US,” Kris says, “simply because the number of E85 Z4s in the States makes production of go-faster bits viable.”
While in some respects, that lack of choice made things easy, Kris still needed to make the right decisions to achieve the goals he wanted, so on top of his research he talked to the guys at SouthernBM, a local and highly renowned specialist shop. The end result was a pretty tasty combination of American tuning parts, such as a 34-row Zionsville radiator, Vibra-Technics engine mounts, a StopTech Trophy BBK, Turner anti-roll bars, Hyperco Linear Race springs, Rogue Engineering rear shock mounts and adjustable rear control arms, and an APR Performance carbon GT wing. In fact, JRZ RS-1 dampers aside, the only brake and suspension parts Kris didn’t get from the US were the Vorschlag E46 M3 camber/caster plates and Carbone Lorraine R6E pads. Even inside, Kris relied on US know-how to help improve the already pleasant Z4 M cabin in the form of beautiful and custommade anti-slip pedals from Ultimate Pedals. To these he added a Recaro Pole Position bucket for himself and a ZHP-style weighted BMW gear knob.
Rather surprisingly, given the S54 engine is from the E46 M3, Kris had trouble finding options even here, specifically in the form of supercharger kits. At the time, only ESS kits were available, so to get the power he wanted Kris had no choice but to go with the company’s VT2-525 blower, intercooler and intake manifold kit. Currently it makes 403whp and 228lb ft of torque. Of course, ESS equipment is hardly second-best, and thanks to upgrading the included Setrab oil cooler for a bigger one, Kris reckons even now, with more options on the market, he wouldn’t change a thing.
Thankfully, Kris’s other engine tuning options were easier to come by. He decided on a beautiful Tekarbon carbon fibre engine cover to spruce up the bay, and a KSS Performance valve-controlled exhaust to allow him to stay street-legal and not annoy his neighbours on those early mornings when he heads to the track yet still enjoy the full metallic scream of the S54 when he gets there. And he’s there a lot.
In fact, thanks to holding onto his WRX for more practical driving, Kris can afford to use the Z4 as almost purely a toy. This freedom, combined with his desire to learn from instructors on a regular basis and to study his own on-board data stats, means he’s able to really enjoy the car at the Marque Sports Car Association (MSCA) sprint days he attends regularly. He actually won his class in both 2014 and 2015.
Not that it’s all been plain sailing on the way to the top. While Kris has generally been very careful to build the car in a holistic way, avoiding many of the pitfalls others fall into, there have been challenges and even a scary on-track moment coming from a rare lapse of judgement when it came to both on-track behaviour and the order in which he fitted his mods. In terms of the challenges, the biggest was getting rid of the stock suspension setup’s on-track understeer. “For a car that handled so well on the street, I wasn’t expecting so much understeer,” Kris says. “An additional strut brace didn’t help. Wider front tyres didn’t help. Additional front camber didn’t help much either. Nor did changing my driving style to add some extra trail braking. It wasn’t until I swapped the suspension to the current coilovers and anti-roll bars and was able to stiffen the rear relative to the front that I was able to get the car to rotate like it should.”
And that scary moment? That was the result of what turned out to be an unwise decision to head to Calder Park, a track with one of Australia’s longest straights, on stock brakes (albeit with nearly new pads) despite having fitted the supercharger kit. Now, in his defence, Kris says the brakes had been ordered at the same time but not arrived before the last-minute spot opened up. We’ll let him tell you what happened next: “Halfway through the day, the pedal was starting to feel a little sketchy, and I began a cool down lap so I could come in and inspect the pad material. Part way into that lap, though, a supercharged Honda Civic tore out of the pits ahead of me, and the red mist descended. About a minute later he was still in front as we hit the main straight. At the end of it, as we were both hitting 220km/h (135mph), some semblance of rational thought returned and I started braking slightly before my marker because of my earlier concerns. Too little, too late. Under my left foot I could feel little more than air. Brake pressure was non-existent.”
As he later learned after pumping a whole extinguisher into the front left caliper, the pad material had just crumbled away by that point, leading to piston seals melting and fluid spraying everywhere. Luckily he still managed to save it, steering the Z4 around the Civic and through the narrow gate at the end of the straight before spinning to slow down in the field beyond. Safe to say, the StopTechs went on straight afterwards!
One additional benefit of fitting the big brakes was that they necessitated a wheel change. Never a fan of the OEM design, Kris had previously chanced upon a forum member running Volk Racing G2s in the same matt black as his own Z4 and decided they were perfect. And, as luck would have it, a member of a different forum who lived locally was selling a set just when Kris needed them. “They must have been the only used set of wheels in the correct fitment available locally at the time, and possibly ever since,” he says. “I was so happy with them that when it came time to get a separate set of track wheels I went straight to Volk, who made me up a set of TE37SLs that, again, are exactly what I wanted.” It’s hard to argue with Kris’s choice, too.
Japanese wheels often look great on BMWs and this is no exception. The relatively rare G2 design’s sharp edges and rounded curves, especially, match perfectly with the E85 Z4 M Coupé’s similar mix of lines, keeping the car looking current and fresh, despite now being ten-years-old. And thanks to Kris’s focus on getting the handling, power and braking right, it’s now a car that doesn’t just look great but one he can enjoy driving for years to come (like his WRX, he has no plans to part with it though).
“The Z4 M, to me, represents a challenge, one that never gets old. There is such a fine line between getting it right and everything going to hell in a split-second. Sprinting along the right side of that line is one of my favourite things in the world.”

With 600hp from its supercharged S54 , this RHD converted #BMW-E30 M3 is at the top of its game. An S54-swapped, supercharged, 600hp E30 M3 is about as good as it gets… Words: Elizabeth de Latour / Photos: Steve Hall
You know this is going to be good. You’ve seen the front cover, you’ve read the taster, you’ve probably not been able to restrain yourself and may have already been drooling over the pictures, so you know that you’re about to read about something special. Certainly it’s going to upset some people because there’s a lot going on here, including the RHD conversion and the S54 swap carried out on a genuine E30 M3, so in the eyes of many purists that’s it ruined, basically. But we’re open-minded here at PBMW towers and if you’re reading this mag then we’d like to think that you’re cut from the same cloth and can appreciate cars that might offend those of a more delicate disposition. And this is a car that most definitely deserves some appreciation.
BMWs have always been a big part of Sam Le Fevre’s life. The 31-year-old construction company director first fell for the Bavarian marque when his oldest brother picked him up from school in an E30 325i. “For me, it’s the four decades of motorsport heritage and the connection between driver and machine that makes BMW so special. You just don’t get that with other affordable marques,” explains Sam. And the E30 M3 is arguably the ultimate definition and concentration of that BMW essence.
He began his BMW journey with an E46 M3 Convertible and while his car history is mixed, with a couple of fast Fords in there for good measure, his passion for BMWs, and particularly for the E30 M3, has clearly bubbled to the top. “I’ve always loved the E30 M3; it is a true homologation model with a chassis that draws you in and gives you confidence,” he says. And with the means available, a purchase seemed inevitable, though it was not without some drama, as he explains: “I found the car on PistonHeads advertised at a trader for £16,000. I arranged to see it and travelled down to Sussex. I looked the M3 over and told the trader the car had been in an accident and that he needed to revise his price. I said the car needed to go on a jig as I noticed the passenger wheel was sitting back 15mm towards the skirt. He refused and said that it was just an alignment issue. I left my details and told him to contact me if he didn’t have any luck. A month passed and I got a call asking me if I wanted to come down and view the car again. I said there would be no point if he was still asking for the same sort of money. I went and viewed the car for the second time and told them I wouldn’t be coming back if we couldn’t do a deal on this occasion. We haggled and eventually agreed a sale for £11,000.”
Even with the potential chassis problem that was something of a bargain, especially considering the selection of #Alpina additions the car was sporting and the small matter of the freshly rebuilt engine, totalling a cool £6000 in bills.
Now all that was needed was some inspiration and, luckily, Sam’s favourite BMW magazine happened to provide just what he was after: “I was reading #Drive-My when I came across Del Sanchez’s masterpiece: the E30 M3 with a S54 powerplant. To me this was perfection – BMW’s best chassis combined with its best six-cylinder engine! So I thought I would have some of that in my flavour. As soon as I picked the car up I drove it straight to the transplant centre, aka Munich Motors in Wokingham, to see the man himself, Clive Sanchez. He checked the car over, said it needed some jig or bulkhead work and he booked it in for two months later. I got impatient after a fortnight and phoned Sue, his wife, and said I was dropping the car down because I was doing my driveway (a poor excuse, I know). He started doing the teardown ready for the S54 transplant and that’s where we ran into problems as the shell needed major surgery!”
The engine came first, though, and while Sam knew he was fitting an S54, he wanted to add a little extra spice: “The plan was to build something with forced induction, either a turbo or supercharger. I spent a Saturday at Munich Motors with Clive looking around the engine bays of the two S54 transplanted E30s that they had down there. After careful consideration, measuring and thinking about the driveability of the car, I decided that the supercharger route was the only sensible option. The engine came from Quarry Motors and while there was a problem with the Vanos system the guys at Quarry sorted it out with little fuss and we then added an ESS VT2-550 supercharger.” On its own the 550 kit makes an impressive 550hp according to ESS along with 340lb ft of torque. But, of course, there’s a lot more to a build like this than simply slapping a supercharger onto a stock engine. Sam’s powerplant has been beefedup with a few supporting mods to assist with its longevity and add some additional power because, you know, 550hp isn’t nearly enough in an E30…
On the sensible and practical front, the engine has been fitted with an M50 sump for space reasons and the Vanos was rebuilt with Z4 M bolts. The big end bearings have been uprated and fitted with stronger ARP bolts, there are custom crank and supercharger pulleys, a Storm Developments Garrett chargecooler, a custom E36 M3 Docking Engineering radiator, Denso iridium spark plugs, Bosch coil packs, Bosch Motorsport grey injectors, a Bosch 044 fuel pump and a Fuel Labs fuel filter. The secondary air pump and rear lambda sensors have been deleted and the engine has been treated to an Alpha N conversion and a Setrab oil cooler.
“Once the engine had been put in the bay, that’s when we hit the serious problem,” Sam continues. “We realised that the chassis legs and bulkhead had been repaired very poorly. I was in utter despair thinking I was going to have to scrap the car but I decided that the car was not going to beat me. I couldn’t find a decent E30 M3 shell anywhere so I figured that, as #BMW had built every other M3 in RHD, I’d make my own RHD E30 M3. I managed to source a clean 316 shell that had covered only 50k miles and had blown a head gasket with a plan to re-shell the car completely and take all the quarter panels etc. off. But after dropping the shell off to Eddie at Crash Repairs in Edmonton he said just bring in the front end from the 316 shell and he would take care of it. To say that I was a little apprehensive was an understatement. I went up to Big Bavarian Beauties on a Saturday morning with my petrol disc cutter and set about cutting the front half of the car and roof skin off, and putting it in the back of my van, ready for the journey back down to London. I dropped the front end down to Eddie and he said that he’d need the car for four weeks and that the shell needed two new inner and outer seals and a few other parts. I got all the bits and dropped everything off with him on a Friday.
When I got a call on Monday asking me to come over I was expecting the worst, but I was amazed to see the car complete and sitting on jig pins. Eddie had basically drilled out all the spot welds from the A-pillars, bulkhead and floorpans and grafted the 316 front end straight on back in the factory spot welds in a weekend. I was gobsmacked. We picked the shell up and drove straight up to SPL for a full acid dip and e-coat session.”
With the chassis drama dealt with, Sam and the guys could get on with the task of getting everything running right, but that wasn’t an easy process either, as he explains: “Once Clive had the car running we started coming across numerous problems. The biggest one was that the car was down on power dramatically compared to what it should have been making. Clive suggested I visit Storm Developments in Aldermaston so I drove over there where owner Andy and I instantly clicked.”
Andy used his engineering superpowers to diagnose the problem and had Sam removing the front bumper to access the chargecooler, which Andy duly whipped off and bypassed before telling him to take the car for a spin up the road. “Well that’s exactly what happened,” laughs Sam. “I pulled out of the workshop, stabbed the throttle and the rear wheels lit up! The car had rocketed from 260hp to 325hp in an instant but it was still down on what we were expecting.”
So Andy’s next plan of action was to fit a Garrett chargecooler. This helped take power up to 410hp but now the exhaust wasn’t pulling its weight. “Andy suggested getting the exhaust modified,” says Sam, “so I contacted Hayward & Scott and dropped the car off with them along with a drawing Andy had produced so they knew what sort of system was required. It now sounds amazing.”
Exhaust sorted, Sam headed back up to Storm Developments where Andy changed the plugs and coils before strapping it onto the dyno. “We were very disappointed when it only made 450hp,” says Sam, “so Andy measured the boost and it was way down on the 7psi it should have been producing. He worked out the sizes for the pulleys we needed to get the boost we were aiming for and I went off to get them made up. I popped back to Storm a few weeks later.
Andy took the pulleys off me as soon as I got out the car and fitted them on the spot before he told me to put the car on the ramp.” This was the moment of truth and the numbers didn’t disappoint: the M3 putting down a seriously impressive 580hp and with a few tweaks to the map the final run produced 604hp. That’s more like it! So, Sam now had a RHD E30 M3 running one hell of an engine setup. But that alone does not make for a complete package. It was time to address the suspension, and Sam was very particular about his upgrades in this department. “I took a ride in some cars with H&R and KW coilovers and found them all to be uninspiring with both manufactures unable to do custom damper designs,” he explains. “I was recommended a company called AST by Demlotcrew who raved about the products so I contacted them and spoke to Curtis Woodman who told me to bring the car up for him to have a look at and see what we could come up with. After driving over to Cheltenham and discussing the options we nailed down a damper design for the rear, which is basically an inverted wasted shaft DTM replica with custom valve and spring rates.
The car has also had the front subframe reinforced, aluminium control arms, Eibach anti-roll bars, Treehouse Racing front control arm bushes, dual diff mount and BMW Motorsport bushes as well as countless other additions and tweaks.” The brakes also needed attention and for some serious stopping power Sam turned to AP Racing, fitting the car with a set of sixpot front calipers with 330mm discs and four-pot rear calipers with 315mm discs, which are more than enough to slow the E30’s lightweight frame down from silly speeds. The drivetrain has also been beefedup, with the S54 mated to a ZF five-speed gearbox from an E36 M3 3.0 that’s been fitted with a TTV lightened flywheel and Sachs Hybrid HD clutch. A CAtuned modified chromoly driveshaft (this E30 M3 has a bit of an appetite for driveshafts) and a Demlotcrew 3.15:1 Motorsport diff with a Z3 M modified diff cover were also fitted.
While the performance modifications are absolutely full-on and barely contained, the styling is the complete opposite and Sam has kept things very subtle, allowing the E30 M3’s iconic good looks to shine through with only the slightest smattering of visual tweaks. We’ve got to go for the wheels first.
They are genuine BBS LMs – one of the Holy Grails of the wheel world – and are pretty rare to boot. There’s quite a story behind Sam’s acquisition of them. “I’ve always loved BBS splits rims,” says Sam, “and couldn’t have the usual BBS RS type of wheel as they wouldn’t fit over the AP Racing BBK, so the hunt started for a set of staggered LMs. Well let me tell you, you have more chance of your numbers coming up than you do of finding a set. After being let down by a couple of sellers, I was contacted through one of the forums by a guy called Angel from Toledo in Spain. He had the wheels I wanted but wasn’t willing to post them; no problem, I said, I could come and collect them myself but that ended up being rather sooner than I anticipated as I received a call after work one Friday from Angel saying that I needed to collect them before the next weekend or he had another buyer lined up.
So my brother and I rushed home, picked up the family 335i and told my wife that I was going to Spain for the weekend, leaving her to cope alone with our four-month-old baby boy. We’d also been burgled just two days previously, so she was not impressed! We booked the tickets anyway, chucked a case of Red Bull in the car and set off on a mini endurance race from London to Toledo and back again!” Now that is dedication and shows just how far some people are willing to go for the right set of wheels, but the impromptu road trip was absolutely worth it as these wheels look insanely good on the car, especially after their recent refurb and darker centres.
For the outside, Sam looked to BMW’s other M3 offerings for inspiration, opting for an Evo 2 chin spoiler with carbon splitter and an Evo 3-style spoiler with a carbon gurney flap. A set of smoked Hella front lenses and indicators were added and Sam tinted the rear indicators for the finishing touch. Inside, the car already had a set of very rare Recaro LS seats in mint condition but covered in the very dated check pattern that Sam was not a fan of. Having seen an E30 Europameister and fallen for that interior, Sam took his interior over to Adam at B Trim. The seats have been trimmed in black Nappa leather with silver stitching, with B Trim also making a non-sunroof black headlining in BMW fabric and recovering all the pillar trims in black vinyl. You’ll also find an M Tech 2 steering wheel and an E36 M3 3.0 gear knob.
It’s taken Sam three years to get to this stage with the car and we wager that back when he was struggling to decide whether or not to even keep it he couldn’t have imagined it ending up like this. For a lot of people, their projects seem more like a sprint rather than a marathon, with owners desperate to meet show deadlines for the big reveal. This build, however, has definitely been the latter. And while it’s been far from plain sailing for Sam, the journey has been well worth every hardship as the end result delivers the sort of pleasure and enjoyment nothing else can. “The look on a Ferrari F430 owner’s face after being wasted by my scrap yard survivor was priceless! I was laughing like a child!” Sam says. For some, this car might go too far but for us, going that bit further is what it’s all about.
