With its subtle looks, this 135i can slip under the radar, which is handy as it’s got 460whp on tap. This 135i might look fairly ordinary but appearances can be deceptive and there’s a lot more going on here than meets the eye… Words and photos: Chris Nicholls.
Disappointment is sometimes a powerful motivator. Sports teams that lose the championship one year have been known to turn that negative feeling into a springboard that pushes them to win it the next. So it was with Pete Agas and his 135i.
Initially, he wanted a 1M Coupé, but only 200 came to Australia and he missed out on the allocation. He didn’t let that get him down, though. Instead, he purchased an E82 135i and used the leftover funds to change almost every mechanical component to make it much faster than a stock 1M ever was.
The story begins back in late 2012, when he first purchased this Alpine white example fresh from the dealer. Having been inspired to tune cars ever since his youth (when watching Stephen Spielberg’s debut feature – Duel – made him think about tuning cars so he could outrun a psychotic truck driver), Pete wasn’t going to leave it untouched for long, and after posting a few pictures of it in its factory state on his online build thread (complete with the caption: ‘stock… yuck’), he started to modify it to suit his tastes.
As for those tastes? “I build, tune and customise my vehicles for performance over appearance,” he says, and as you can see, the finished car reflects that. APEX ARC-8 wheels, StopTech BBK, #Hartge silencer and M Performance carbon bits aside, there is no indication from the outside that this machine puts out 460whp at low boost and pounds around race tracks with ease. Even looking under the bonnet yields nothing to the casual observer, and unless they were looking hard, enthusiasts would only spot the AFE Magnum Force Stage 2 intake and M Performance Power Kit 2 as well. Almost everything that means anything is hidden on this build, and that’s the way Pete likes it, especially as it makes it that much easier to goad other, supposedly faster, cars into a little challenge. “I frequently drive around the South Yarra area in Victoria where there are plenty of beautiful Porsches. I may have completely decimated a couple of them in a quick squirt contest…” he says with a grin.
Of course, his E82 didn’t become this fast overnight. Indeed, having missed out on a 1M, he initially wanted just to match that car’s handling, with pure grunt not really on the radar. And even then, for the first year, Pete only drove it around with limited mods. An M Performance exhaust and exterior bits and some Rays G25 wheels upped the game from stock, but they were hardly going to help Pete reach even his initial goal. That’s why, after that 12 months, he started amassing E9x M3 suspension parts in bulk, along with other bits and pieces, so he could be ready for the next stage.
Those E9x parts included sway bars, control arms, bushings, camber link kit and strut tower brace, to which he added Swift springs. Having basically matched the 1M’s key suspension elements, Pete then moved onto the brakes, with M Performance discs, Cool Carbon brake pads and Hard Braking front titanium shims. For a little extra grunt, he added the aforementioned Power Kit 2 and controlled it via a Quaife 3.08 helical LSD in a VAC finned, clear anodised cover. A Burger Motorsports clutch delay valve and clutch stop helped in the driveline department as well. Finally, a few extra M Performance exterior and interior parts helped round it off. Until the most recent major upgrades, the diff was actually Pete’s favourite component as it improved traction no end. “The LSD just puts the power down without the e-Diff having a field day. It was easily the most notable change when driving the car back home from the workshop for the first time.” The fact the Quaife diff works with the stock traction control is a bonus, too, even if Pete doesn’t need it in the dry.
Now, you might think at this stage, having reached his initial goal, Pete would be satisfied and call it a day. After all, he had already created a very quick, but still very usable road car. However, the fact you see this rather faster beast before you shows he wasn’t done. What prompted him to go further were two new discoveries. Firstly, having gone this far into the BMW tuning world, he’d found a “huge amount of aftermarket potential within the BMW brand”, as well as a highly supportive and knowledgeable community to go with it.
Secondly, having built a track-oriented car, Pete was hardly likely to keep it purely on the road, and a visit to Phillip Island one day proved rather comprehensively that while strong, his build wasn’t perfect.
“I quickly discovered the platform needed brakes and cooling,” Pete tells us. “I also learned very quickly of the possibility of a spun rod bearing when pushing wet-sumped platforms on the track, so I quickly picked up an oil pan baffle to prevent this from happening to me.”
Having discovered these weaknesses, Pete also bolted on an oil cooler and decided that even the upgraded brakes he had weren’t going to cut it. So, as part of the final stage of mods, he purchased a StopTech BBK, with ST60 six-pot calipers on the front and ST40 four pots on the rears, matched with StopTech’s own Street Performance pads.
These clamp down on with Trophy Sport two-piece slotted discs to provide a significant upgrade in braking ability. Indeed, these are now Pete’s new favourite parts. “The new brakes not only look great, but they have an amazing pedal feel, are completely modular and replaceable and have a huge range of available pads.”
That they sit this high in his estimation is a big endorsement, given the rest of the upgrades he fitted at this stage. In the engine bay, he installed a Pure N55 Stage 2 turbo, an AR Design downpipe, Maddad midpipes and the aforementioned Hartge silencer on the hot side. He also fitted the previously mentioned AFE Magnum Force Stage 2 intake, an ETS five-inch intercooler and lower charge pipe, an Evolution Raceworks black anodised chargepipe and GFB N55 diverter valve upgrade on the cool side. Unsurprisingly, given the company’s reputation, a Dinan Stage 3 135iS tune controls the lot.
To further enhance the car’s abilities on the track, Pete also added Dinan Racing adjustable rear toe arms, Dinan front control arm bushings, Turner Motorsport solid aluminium rear subframe bushings and Ohlins Road and Track dampers. Finally, some sticky Hankook RS-3s on those handsome APEX ARC-8 wheels put all the power to the ground.
The results are quite startling. Given the sticky rubber and LSD, you’d think traction wouldn’t be a problem, but with TC off, Pete was able to spin up the wheels well into third gear on our short spot-shoot drive. “This is with the turbo at 15psi, remember,” Pete reminds us. “It’s capable of 27 or even 30psi. Frankly, I think it’d be undriveable on the street like that. I would need drag slicks or something.”
He’s probably right. The biggest impact, though, came from the fact that the power just kept on coming. Starting from around 3000rpm, it genuinely didn’t stop until very close to the redline. Owners of modern, well-tuned turbo cars will no doubt be nodding along to this in recognition, but for those who haven’t experienced such a longlasting rush, it’s quite the memorable event.
Thankfully, all of Pete’s suspension changes keep the car a lot more pinned to the ground, even if traction is a bit of an issue. It’s firm, no doubt, but even the harsh, sharp-edged bumps on Melbourne’s often lumpen roads didn’t jar particularly. It’s a testament to both the quality of the parts and Pete’s careful selections. “I like to think with the right amount of planning and research, most, if not all risks [when building a car] can be mitigated,” he says knowingly. “I checked, re-checked and triple-checked the parts that were chosen for the car and I paid very close attention to their fitment and quality before proceeding with the purchase. That research, coupled with the highly talented team over at SouthernBM (his chosen workshop), made the process easy.”
So, having now built a sleeper that can not just match a 1M but surpass it in every measure (bar width), is Pete satisfied? Is he done? Of course he isn’t. Soon after the shoot, he fitted some Kerscher 1Mstyle front wings and eventually, plans to turn it into a roadregistered track car, complete with rear seat delete, half-cage, Recaro Pole Positions, lithiumion battery, Evolution of Speed N55 manifold, E85 tune and carbon bonnet.
This would leave him without a daily driver, though, so what gives? Well, on 14 October last year, Pete watched the livestream as #BMW introduced the M2, and soon after, strode into his local dealership and ordered a manual one in Long Beach blue. We guess he never did get over the disappointment of the 1M after all…
StopTech ST60 front BBK boasts 355mm discs and six-pot calipers, necessary when you’ve got 460whp to play with.
