    HARDCORE S54 E30 Thunder from Down Under

    SKIN DEEP #S54-swapped E30. Words and photos: Chris Nicholls. They say you shouldn’t judge a book by its cover and Andrew Burke’s home-built, DIY-painted E30 is exactly the reason why.

    “Why are you shooting that little thing?” says a passer-by during the shoot. I casually pop the bonnet and see his eyes widen. “Jeez, there’s some work gone into that,” he says, before firing off a few photos on his phone and walking away. This sort of thing happens several more times during the shoot and it’s easy to understand why.

    From a distance, this is just another E30 track car. The matt black paint, done as a last resort after troubles with the painter, is hardly the last word in beauty and the stock M Tech II body kit isn’t going to set anyone’s world alight either. No, things only get interesting when you get close. It’s then that you see the custom Forgeline wheels and fat, circle-track StopTechs and imperial-sized AP Racing J-hook discs (chosen because imperial gear is cheaper than metric). Next, you peek inside and notice the #Motec M800 ECU sitting on a custom carbon plate on the floor. And the oil lines for the Peterson dry sump kit running next to it. And the Motec C127 colour dash logger and Tilton pedals. It just doesn’t stop. Finally, you pop that aforementioned bonnet and see the immaculate S54 with carbon cover and CSLreplica intake nestled in-between the strut towers, surrounded by Goodridge Teflon hoses and a Peterson oil pressure primer pump. If ever there was a car to prove that sometimes, the opposite of the idiom ‘beauty is only skin deep’ applies, this is it.

    The back story of this Australian E30, as you might suspect given the engineering involved, started several years ago (six to be precise) when owner-builder Andrew Burke picked up this 325is to be a street-registered track day build. Having got tired of risking his E92 335i road car on the track, he thought back to a 1989 E30 brochure he got as a kid and decided that would be a better bet. As most builds do, things started off small. Some H&R springs and Bilstein Sport dampers, rebuilt stock brakes and bolton exhaust, a short shifter and new Recaros did the trick for six months, but one track day at the wonderfully nicknamed Haunted Hills circuit (actually Bryant Park) in his home state of Victoria, Andrew noticed puffs of blue smoke on overrun thanks to some keen-eyed photographers. “That was all the excuse I needed to go ‘Oh, this motor could potentially have some kind of small issue in the next three, six, nine, 12 years, I should probably just swap the engine out right now’” he laughs.

    Thus began a long and involved process of finding and fitting a new motor. Having decided a resto-mod approach was best, he settled on an S50 and sourced one from the UK, but all was not well. “As all UK motors are, it was covered in corrosion, all the aluminium bits were all pitted from the salt and whatever other calamities occur over there in the middle of winter, so I didn’t do a whole lot with it other than strip it down to a short block and basically sand blast all the things,” Andrew says. Having cleaned it up, he found it still good enough to use, so left it standard internally and got to work fitting it. On went an E34 sump and 12° angled double-shear shift rod to get the now-twisted stock G250 five-speed to work with the AKG DTM shifter, some custom-made exhaust manifolds from Andrew Nicholls at Meridian Motorsport and a VFT E36 DTM-style carbon air box specifically designed to fi t S50s in E30s thanks to a notch cut into the back to clear the brake booster. To ensure that it all ran, Andrew cut and re-connected the stock harness himself and fitted an Alpha N ECU chip.

    However, while he may have cleaned it up, it turned out the engine’s not-so-perfect appearance was rather more indicative of its condition than first thought and sure enough, the number five journal went at a Winton Raceway track day in true S50 style. “A $350 tow truck ride home later [Andrew not having a trailer at the time and Winton being two hours from central Melbourne] we were sitting in the garage, the old man and I, saying ‘Well, we’re going to have to fix it, I guess’”. Andrew admits that even at that point, the idea of fitting an S54 came into his head, but he wasn’t quite ready to quit on the idea of an S50-engined E30 yet, especially having done so much work to make it fit.

    Thus, he decided that, rather than throw everything away, he would build a proper race-spec S50 and see what happened. Sadly, it’s here that Andrew suffered the all-too-common “bad workshop experience.”

    After searching around for a well-regarded builder, he thought he’d found one in a former Team JPS BMW factory race engineer in New South Wales, but while the specs were suitably serious, complete with 11.6:1 Wossner pistons, Pauter I-beam rods, 296° cams, Supertec Inconel valves and the current Peterson dry-sump system (designed to avoid ever spinning a bearing again), it “never made any real power.” “Without going into too much detail, it just fell on its face above 6000rpm,” he says. Worse still, it didn’t even last that long. A mere 500km of track work later and Andrew was sitting on the side of the Winton tarmac with two holes in the block from a rod and rod bolt respectively, oil pouring out everywhere and his car partially in flames thanks to starting a grass fire underneath it. The worst part? A postmortem found the likely cause to be poor assembly.

    “As I pulled the bits off the motor so I could get it out of the chassis, I found one of the ARP rod bolts was poking through the block on the exhaust side. I didn’t see it originally as a result, but it was poking through with all of its threads still intact. So it was not like the bolt snapped – it was like it completely unscrewed itself – and I can’t imagine a bolt that’s designed to be torqued to yield, if it was properly fastened, would have come undone. End of story. So that was that, which was a bit unfortunate.”

    Unfortunate indeed, and at around AU$30,000 (£17,000) for the engine, expensive. Andrew adds that figure doesn’t even include the cost of ancillaries fitted to deal with the extra power, the current 8x17” Forgelines, the previous SL6R and SL4R Wilwood calipers and discs (since replaced by the StopTechs because Andrew bought another road/track E30 he wanted to put those on), the custom-built AST two-way adjustable coilovers (again, since replaced by custom MCS two-ways) and several other mods besides. However, Andrew wasn’t prepared to throw it all away, so after convincing his wife he “wasn’t silly,” he pulled the trigger on a mint S54 with just 18,000 miles on it out of a wrecked Californian Z4 M.

    Being so new and from California, this motor was in stunning shape. There was no dust behind the water pump or alternator pulleys and even the internals, which Andrew inspected when he pulled off the sump to fit the Moroso dry sump pan, were unvarnished.

    Given he had no money to put new internals in it, this worked out perfectly. Plus, the S54 made more power stock than his built S50 anyway, so in it went, with only a Karbonius CSL-replica air box – fitted because the StopTechs meant he no longer needed the booster – a Racing Dynamics carbon engine cover, new custom exhaust manifolds (again from Andrew from Meridian, who by then had moved on to start his own venture called Trackart) and a few other mechanical pieces like an Eisenmann exhaust needed to make it work. At the same time, Andrew realised that to actually run the thing (especially given he was keeping Vanos and drive-by-wire), he would need to upgrade his dash from a set of Stack gauges to a Motec logger to ensure the necessary input and output numbers, and after contacting Jason Ingram at Advanced Motorsport Electrics to do the concentrically-wound, DR25 heat-shrunk harness and install it, he got it tuned by Lee at Melbourne Performance Centre and brought it up to Broadford State Motorcycle Centre for a shakedown, which is where we did the shoot.

    His impressions of the car now it’s finished (bar a cage)? “I was thrilled with the way that it handled and the way that it stopped even back when it had the second S50… but I was deeply disappointed on some level that it didn’t make as much power as I was expecting. It was certainly fast enough, but it never felt brutal, I guess. Whereas the S54 is still not crazy by any means, it just feels a lot more angry. It feels significantly more powerful.” Given this first shakedown was conducted at only half-throttle, that’s a brilliant portent and suggests that when this E30 is finally unleashed, its unassuming looks, combined with all that power and handling, will mean the opposition won’t see it coming.
