It’s truthful to say that, in the event you’re a BM fan, then virtually by default, you may be an E46 M3 fan, and that’s positively one thing that may be mentioned of Eumir De Leon (@s54_power). He’s most positively a BMW fan, and the Bavarian model has been a giant a part of his life for a very long time. “I’ve been into BMWs ever since I used to be a little bit child,” he begins, “within the ’80s, my father owned a brand new E30 325is M Tech with gold BBS wheels and Bilstein suspension, exhaust and so forth., then once more once I was in my early teenagers. I vividly bear in mind him at all times washing and taking good care of his BMW. The sounds of tyres chirping in between gears, the engine revving, and being glued into the seats would at all times put a smile on my face,” he says with an analogous smile.

The E30 was his first real love, and unsurprisingly, he wished to comply with in his father’s footsteps. “I used to be purported to be given my father’s final E30 as my first automobile however issues received sophisticated for him so, that by no means occurred,” says Eumir, and as an alternative, he took issues into his personal palms and purchased an E36 325is as his first automobile. He didn’t go straightforward on it, thoughts, and in addition to some Recaros, Fashion 5s and coilovers, he put collectively a {custom} turbo package. However, as nice as that turbo E36 construct was, there was one other automobile apart from that first E30 that was additionally on his thoughts.

“As a child shifting all the way down to Miami from NYC, I bear in mind seeing the E46 M3 when It was new, in Laguna Seca blue. I bear in mind considering how futuristic and beefy-looking it was. I used to surprise if I’d ever be capable of afford that automobile…” he reminisces. “Quick-forward a few years later, once I was a tech at a BMW efficiency store, there was once an Alpine white, track-ready E46 M3, with the CLS airbox, Recaro seats and Enkei NT03s. Seeing it totally specced out made me wish to put these mods on my future automobile. Listening to it do a number of pulls on the dyno and listening to the high-revving S54 complemented by a full exhaust and that CLS consumption would simply seize my consideration, like ‘Wow! I must have this already!’” he grins, and the M3 that’s parked in entrance of us is proof that goals do come true.

“Once I started to seek for the E46 M3, I particularly wished an Alpine white with Cinnamon inside or Imola. At the moment, costs had been by the roof for that spec, so the subsequent color I used to be comfortable to accept can be the Silver gray. As everyone knows, that’s one of many two colors the E46 M3 CSL got here in. I regarded on-line for months and couldn’t discover an unmodified M3 anyplace. My good pal Fabian discovered the M3 I used to be searching for on Craigslist. I went to take a look at it and instantly I may inform how well-maintained the automobile was. It was bone-stock aside from the rear wheel spacers. The earlier proprietor regarded very nervous to promote me the automobile as I regarded younger, and he seemingly thought I used to be going to damage it. I instructed him, ‘Don’t fear, I’ll present you what I’m going to do to this automobile in a number of months’. Each time we run into one another, he’s amazed by the automobile like, ‘Wow! That is on one other degree!’” smiles Eumir, and that’s as a result of it truly is.

Tuned E46 M3

Having been impressed by that E46 M3 within the workshop all these years in the past, there was no beating in regards to the bush right here, and Eumir knew precisely what he wished to do. “My plan was to totally restore and construct it to my spec that I’ve at all times dreamed of getting,” he grins. For those who can’t inform from wanting on the pics, this was no small-scale informal construct, and Eumir has put seven years of labor into this tuned E46 M3, and each second of that point was 100% value it.

The S54 that resides below the bonnet has undergone an terrible lot of labor, and whereas your consideration is straight away drawn to that superior CSL airbox, there’s much more occurring below the floor. Eumir has made certain that it doesn’t simply carry out like a dream, he’s additionally made certain it’s going to final. “I’ve totally bulletproofed the complete Vanos unit together with totally sprucing the housing simply to let or not it’s recognized that’s it’s been labored on,” he grins. “I’ve additionally modified the rod bearings, fitted a Bimmerworld Vanos oil line, Energetic energy pulleys, and a Mishimoto electrical fan shroud with Spal electrical fan. I’ve additionally added a CSF aluminium radiator, Mishimoto higher and decrease silicone radiator hoses, Supersprint exhaust manifolds, and that CSL consumption with {custom} CSL Alpha N tune,” says Eumir with a glad smile. That spectacular array of enhancements and upgrades imply that he can get pleasure from his M3, protected within the data the S54 is now strong as a rock. In the meantime, the efficiency additions haven’t simply given this automobile a soundtrack to die for, they’ve additionally given him 370whp and 279lb ft wtq to play with, making this tuned E46 M3 one significantly speedy machine.

With this being such a radical construct, Eumir has left no space of the automobile untouched, and the chassis has acquired a complete overhaul and improve. “The automobile is at the moment on Air Carry 3P modified air suspension,” he tells us, which little doubt has brought on a big and sudden consumption of breath for a lot of readers, nevertheless it’s Eumir’s tuned E46 M3, and he can do no matter he needs to it. “The automobile’s chassis has been structurally strengthened all-round, beginning with the rear subframe ground reinforcement plates from Redish Motorsport, together with the RACP, a Vince brace and gusset cups package. Each single bush on the automobile has been upgraded with Powerflex, Revshift and AKG, plus I’ve added Hotchkis entrance and rear anti-roll bars,” he says, and that’s a formidable array of suspension mods.

Everyone knows simply how essential wheel selection is in the case of any construct, and Eumir’s is totally top-tier. “Effectively, my dream wheels for the automobile are the wheels I at the moment have, that are the BBS E88s, impressed by Porsche builds,” he smiles. “I’ve gone by different wheels just like the Enkei NT03, APEX ARC-8, then I unintentionally got here throughout a deal I couldn’t cross up with the BBS RS. They had been cool however didn’t match my driving fashion and look I used to be going for,” he provides. The 18” E88s look so good and go well with this entire construct completely, with that motorsport styling simply working so nicely with every little thing else that Eumir has received occurring.

When it got here to aesthetics, as with the remainder of the construct Eumir knew precisely what he wished. “I’ve at all times strived to remain as shut as potential to the CSL, however beefier and tweaked to my actual liking,” he explains, and he’s positively achieved that. The modifications are refined however purposeful, similar to a real CSL, and up entrance sits a CSL entrance bumper and carbon lip, with a {custom} entrance lip guard to maintain it protected from harm, and there’s an identical CSL diffuser on the rear. The distinction with this automobile, although, is that every one 4 arches have been rolled and pulled, and whereas this can be a very refined modification, it serves to present this M3 {that a} barely extra muscular stance and simply that little bit extra presence, and it makes all of the distinction.

There’s nothing refined in regards to the inside, although, and Eumir has created his good driver-focused cabin, which will get to the purpose and appears good doing it. Up entrance sit a pair of Recaro SPG XL single-piece buckets which have been reupholstered in black Nappa leather-based, they usually have been paired with Simpson Racing five-point harness. Eumir made the {custom} rear seat delete himself, and it’s wrapped in Roll-Royce suede for that luxurious contact, and the rear of the cabin is now occupied by a Kirk Racing half-cage. Up entrance, there’s a minimalist steering wheel devoid of any buttons, trimmed in Alcantara and completed with a pink centre stripe. Eumir has additionally added a CAE short-shifter and a CSL carbon centre console, whereas the trim items have been custom-painted. Lastly, as a result of there’s no must lose all of your creature comforts, there’s a touchscreen head unit, new HK audio system and a ten” sub in order that Eumir can get pleasure from his in-car leisure when he’s cruising the imply streets of Miami.

After a lot work and energy poured into this construct over seven years, asking Eumir about his favorite mod virtually appears a little bit unfair, however he doesn’t hesitate. “At present, my favorite is the 4.10 differential I just lately put in. It actually woke the automobile up and added much more snap that it already had, nevertheless it’s simply a lot extra intense,” he grins, and it’s no shock that in a construct that’s all about driving thrills, it’s that mod that will get the largest thumbs-up.

As spectacular and complete as this construct could also be, and as a lot time as Eumir has spent on it, it’s not completed simply but. “I’ve a number of extra issues to do to ‘end’ it, which we all know by no means ends,” he laughs. “Very quickly, I’ll add the ending touches on the automobile’s physique and inside, that are the CSL carbon roof and CSL door playing cards,” he says, and we all know full nicely there’s going to be extra past that. All these years in the past, seeing that E46 M3 within the workshop impressed Eumir to purchase and construct one, and seeing the sensational results of all his arduous work right here would possibly nicely encourage another person to crave and create their good M3 in the future. We actually hope it can as a result of modded BMs don’t get significantly better than this.
