• MASTERCHEF
    Simple on the outside, exciting on the inside, this sexy Aegean blue E30 has been treated to a 3.2 S50-swap.

    Could the E30 be the most engine-swapped #BMW of all time? Judging by the number of feature cars we run that have been fitted with something other than their standard engine, it’s got to be up there. While V8s are a great and popular choice, sometimes you’re just not in the mood and fancy something more traditional where the 3 Series is concerned, like a howling, high-output straight-six, and that’s exactly what we’ve got here.

    Chef Nicholas Arnold is its custodian and the man behind the swap. He’s no stranger to modified cars and BMWs, having worked his way up from a Vauxhall Nova 1.2 through to a selection of Hondas, including an EG Civic that he performed a full DC2 conversion on, and on to a number of BMWs, starting with an E34 525i (as it was cheap and RWD), and including a previous E30, which met an untimely end… “I wrote it off on black ice and I just felt I had to own another one. I found this car on eBay, located in Scotland – it was in good condition and had just had a respray,” says Nicholas. There was also the small matter of it already being endowed with an M52 under the bonnet. “It had a straight-through exhaust, was on cheap Jom coilovers and had an open diff. I changed the inlet manifold and ECU before making bigger plans,” he says – those plans being the swapping in of a more potent powerplant.


    “I put a S50B32 in it as the M52 wasn’t fast enough,” explains Nicholas. “I bought new AKG engine mounts, custom wiring loom, aluminium triple core radiator, Ramair air filter, got a custom-built manifold, ACL race bearings, ARP con rod bolts, M3 3.0-litre oil pump with an E34 baffle sump and a Simons race silencer with a full stainless steel system. It took me six months to put together all the parts for the build and a week’s-worth of work to put it all together. The only problems I had was the servo had to be moved across by 45mm and I had to have a brake linkage bar made up.”

    They say that the waiting is the hardest part and we have no doubt that was definitely the case here as six months to go from capable M52 to 321hp of ferocious #S50B32 goodness must have felt like an age. Let’s not beat about the bush here – the E36 M3 Evo is not a slow car, so just having that rev-hungry lump in the lightweight surroundings of an E30 would result in an absolute rocket ship. But that’s not all, the transmission has also been beefed-up to suit and there’s a five-speed Getrag ’box mated to an E34 M5 Sachs clutch with a 4.5kg billet steel flywheel, E36 propshaft and an E36 2.8 LSD in an E30 medium diff case.

    With some serious power on tap, Nicholas turned his attention to the chassis as it needed some upgrades to be able to cope with the massive increase in engine. “I went for a set of BC Racing coilovers as they’re mid-range and suitable for road and track, Purple Series polybushes with E30 M3 lollipop bushes, again suitable for both roadand track-use, fitted all-new drop links, H&R uprated anti-roll bars, Ultra Racing strut braces to stiffen the chassis and I also had the subframes powdercoated and the rear subframe reinforced due to the increase in power.” The car no doubt drives spectacularly and sits beautifully low. It just looks right, especially on its black 16” Rota Grid Vs, which tie in perfectly with the numerous black details across the bodywork, and make a change from the usual suspects when it comes to E30 wheel choice, as Nicholas explains: “I have the Rota Grid Vs as I like to be different. I also like the Jap, aggressive look rather than following the crowd and having Borbets or #BBS reps.” The wheels are wrapped in Toyo Proxes tyres and sit on a stud conversion, while Ferodo DS2500 pads and EBC discs sit behind the spokes.

    In terms of looks, the E30 really doesn’t need much help – subtle is often best to enhance the styling and that’s definitely been the approach here. The Aegean blue paintwork looks stunning, rich and deep, and the unpainted carbon bonnet is no less gorgeous. Other exterior additions include an eyebrow, crosshair headlights and all-red tinted rear lights. The interior, on the other hand, has received a bit more attention, as Nicholas tells us. “The car started off with a plain standard non-Sport interior but I’ve always had Sport seats in my previous E30s and knew how comfy they were so wanted another set in this car.”

    He spent months searching for a pair of Sport seats but, having drawn a blank, he changed tactic and bought a pair of OMP buckets instead. Of course, no sooner had he installed them in the E30 than a pair of chequered Sport seats appeared at a good price, so he snapped them up and got rid of the buckets. And, as luck would have it, a few weeks later a rear bench, complete with headrests, and in the same pattern, popped up so Nicholas jumped on it, so to speak, and in a very short space of time had put together a rather lovely Sport interior.


    In addition to that he’s fitted a suederimmed #OMP steering wheel with snap-off boss, AC #Schnitzer short-shift gear knob plus a rear blind-equipped parcel shelf. It’s smart, clean, period and suits the rest of the car, with a few subtle hints to suggest that there’s more going on here than meets the eye. We are well and truly in love with Nicholas’ E30, he’s really built himself an amazing machine. From the outside it looks so right – the colour is stunning, the carbon bonnet is spectacular and it really delivers the perfect blend of subtlety and aggression, with no single element feeling over the top or out of place, and that too can be said about the engine. It sits in the bay perfectly, looking so at home, and it’s turned this E30 into an absolute weapon.

    “The huge engine is my favourite mod on the E30,” smiles Nicholas, “because the car is very inconspicuous looking.” He’s going to keep it looking that way, too, when he carries on with the mods this year: “I plan to add some fatter tyres and beef up the brakes as I’m only currently running 2.5 brakes allaround with DS2500 pads and EBC discs which fade after a couple of minutes of hard driving, and supercharge it,” he says, which is really going to turn the heat up on this E30 and take it to the next level.

    The S50 fits perfectly in the E30 engine bay and took owner Nicholas a week of work to get it fitted and running.
