UK two-door is the perfect blend of style and pace. #BMW-3-Series / #BMW-3-Series-Coupe / #BMW-3-Series-E30 / #BMW-3-Series-Coupe-E30
What was once an unassuming #BMW-318i-E30 / #BMW-318i has been comprehensively transformed into a turbocharged beast. Words: Aron Norris. Photos: Scott Paterson.
The BMW E30. Some would say it’s flavour of the month. Others would say it’s their favourite ’80s BMW. Perhaps the infidels among us might even say it’s a little bland. Wherever you stand on the E30, you can’t deny that those Claus Luthe penned lines have aged very, very well. Like a fine wine, these Bavarian compacts are becoming hot property amongst collectors.
Whilst concours classics might be some people’s idea of BMW perfection, others, like Steve Foxall, prefer to use a stock car as a template, a blank canvas if you will. Whilst the 1983 318i you see here might look all sweet and innocent at first glance, there’s a secret lurking. If you’re an OE concours purist, look away now…
Now, when Steve bought the E30, it was in pretty good stock condition because the previous owner had it repainted 12 years ago, which meant Steve could get straight onto the fun of making the 318i his own, something a little less, er, 318i. This is a true driveway project car. Let’s be straight here, it doesn’t take much to make an E30 look great. With those handsome ’80s lines it almost seems perverse to suggest messing too much with BMW’s original formula much at all. I mean, the OE Schwarz black really gleams against the chrome bumpers and trims, all as you would expect I suppose.
Visually, the E30 has lost a few stock items and gained some choice add-ons, but nothing terribly drastic. The front numberplate and foglights have been deleted, which neatens things up nicely, making way for a Jimmy Hill front lip and M Tech 1 rear spoiler to add some ’80s indulgence. There are no wide arches here, nothing untoward you might say. Well, until you peer under the bonnet, that is…
You see, from the very beginning, Steve knew the original M10 engine in his 318i formed no part of his future plans. His vision was always to build a turbocharged sixcylinder M50 beast. Never again would this be a well-behaved practical car. Nobody wants that anyway, right? As luck would have it, Steve managed to find a 1993 E36 325i donor at the scrapyard, which meant things were coming together rather nicely. Operation strip down could begin. Goodbye M10, it was nice knowing you. The donor #M50B25TU powerplant was to provide the perfect base.
For the geeks out there, TU stands for ‘technical update’ which means variable valve timing, i.e single Vanos to you and me. In preparation for the turbo, ARP big end bolts, head studs, race mains, big end bearings, valves, springs and rings were thrown into the mix and a 0.120” MLS Cometic head gasket to lower the compression. Stock pistons, crank and block more than do the job, having been honed to reliably deliver an impressive level of tune.
In order to fulfil his turbo dreams, Steve knew he’d need a fully custom manifold, so a twin-scroll setup was built for his Holset HX35 turbo with 12cm housing. With everything in place, the next step was to build an exhaust. No surprises for guessing that, again, Steve went for a custom setup, this time a Hard Knocks Speedshopfabricated 3” downpipe and exhaust with hidden tip. Continuing the custom fabrication theme, an E34 oil pan (with turbo drain) was shortened and widened to keep the little E30 nicely lubricated at all times. While the old 318 lump was out, Steve took the opportunity to completely smooth and weld the bay, with a fresh helping of Schwarz paint to spruce things up. Blood, sweat and tears ensured the new engine would to take centre stage in the bay, and quite rightly, too.
With the engine taking shape nicely, Steve’s attention moved towards the transmission. His dream M50 build was mated to a Getrag 260 gearbox with a lightened and balanced M20 flywheel to improve throttle response. An uprated six-puck composite clutch, Sachs 618 pressure plate and M3 release bearing were acquired to more effectively handle the increase in power, along with a lightened and balanced propshaft. Steve got in touch with Hack Engineering to order a solid prop ring and the good guys over at SS Autowerks were called upon to provide a set of solid transmission mounts for the build.
To keep everything running just so, Vems management was purchased and a completely custom tucked wiring loom was fitted in the freshly smoothed and painted bay. After some testing, tweaking and mapping, Steve’s E30 was almost ready for action.
Next on Steve’s radar was chassis and handling. The steering rack was swapped out for a Z3 item with custom linkage and a 3.64 LSD was rebuilt with Porsche plates (for tighter locking). Braking was sharpened up with uprated pads and discs, teamed with a Porsche 944 brake booster and braided hoses. SS Autowerks was again involved with the build, supplying BC coilovers with custom springs, front and rear. For a fast road setup, fully polybushed, this car both looks savage and handles as it should.
In the wheel department, the E30 needed grippy tyres, so the obvious choice was to kill two birds with one stone and bolt up some girthy Schmidt TH Line three-piece splits with Toyo rubber. These 16” beauties in staggered 8.5” and 9.5” fitment suit the E30 a treat. Polished dishes with silver centres contrast beautifully with black bodywork.
With over 350hp on tap, this little black beauty is lively on the road to say the least. In fact, the truth is you have to be on the ball just to keep it in a straight line. This is pure man and machine stuff. If you overcook it, there’s no computer to save your bacon, as this car will make you pay for any mistake or lapse in concentration.
The interior of Steve’s E30 is pretty minimalist. You won’t find anything more than you need here. With the focus of this car well and truly centred on the driver, you’ve got a Nardi steering wheel, Delrin shifter, Recaro Pole Positions with TRS harnesses and a custom half roll-cage. That’s it. There’s no fuss – just as it should be with this type of car.
The original black leather interior just didn’t cut the mustard on B-road blasts, so Steve was on the lookout for a pair of replacement front seats and the black cloth Recaros were the perfect upgrade whilst keeping things simple. The rear seats were binned to save some weight and the battery was moved to the boot by using an S2000 mount with shut off. The interior changes have kept things period-correct, which is a definite winner and suit the E30 down to a tee.
Steve’s E30 is testament to home-brew engineering and modification. It might look like a regular E30 from the outside but, make no mistake, this is a driver’s car which will quite happily trounce most modern competition in the performance stakes. There’s something very grass roots about this car and we love it.
Stunning polished Schmidt TH Line 16s are the perfect wheel choice for the E30.
M50 has been treated to a whole host of internal mods plus an HX35 turbo with custom manifold and exhaust system. The bay has been beautifully smoothed.

Is it any surprise that the first car in our top three happens to be an E30? Certainly not when that car is Steve Foxall’s stunning UK machine, as it really is an awesome build and proved very popular with all of you, and with good reason. We saw it in person at a couple of shows and it was a real head-turner, not least of all because of what’s under the bonnet. At its heart is an M50B25, swapped into a wire-tucked bay, with a Holset HX35 turbo strapped to it for plenty of power. There’s also a removable bonnet to show the whole lot off. BC Racing coilovers deliver a sizeable drop over a set of gorgeous, fully polished 16” Schmidt TH Lines, while the interior has been treated to, among other things, a pair of Recaro Pole Position seats and a gorgeous Nardi wood-rimmed steering wheel. The perfect blend of elegant, classic style and serious power, it’s pretty much E30 perfection in a nutshell.
