Is This The Good BMW E46?


Present of arms – who loves a BMW M inline-six engine?

Each my arms are firmly within the air, and I hope most of you could have a minimum of one hand raised. If not, we will’t be buddies. Sorry.

HAZ00545

BMW M’s engineers have delivered hit after hit over time, from the hotted-up M30 within the E12 530 MLE to the twin-turbocharged S58 sledgehammer within the present M3/M4 fashions.

HAZ00543

Since 1978’s M88 – a real engineering magnificence – BMW M straight-six engines have supplied a singular character that different producers simply can’t match.

HAZ00537

I do admit, I’m a through-and-through BMW nerd. As such, I may be blind to the… quirks related to BMW M’s masterpieces. Others would possibly name these ‘inherent design flaws.’

“However, Mario!” you exclaim, “What about rod bearings?” By no means heard of him. “VANOS?” I don’t communicate Spanish, sorry. “Timing chain slip?” Oh, is that the time? I actually should be going…

HAZ00549-Edit

Fantastic, I’m not completely unaware of the issues that Bavaria’s best engineers by no means ironed out of their engines. And that’s earlier than we even point out tough tuning or the provision of aftermarket elements. M-tax is actual, and it may be prohibitively costly to extract huge energy from a naturally aspirated M automobile.

HAZ00551

So what sonorous straight-six engine does Wael have in his 328i, with simple tuning and the flexibility to run severe energy? A Toyota 2JZ-GTE, in fact.

HAZ00552

Let’s drop the humour for a second and communicate objectively – this engine swap makes whole sense.

HAZ00555-Edit

Architecturally, the match is analogous… ish. Each the automobile’s authentic BMW inline-six and its Toyota alternative could be rounded up or all the way down to 30 inches in size, with comparable widths. Whereas this could range based mostly on turbo setup and ancillaries, the 2JZ block seems proper at house within the E46 engine bay.

HAZ00554

A part of that is because of customized mounts for the engine and gearbox; the high-mount Precision 6466 turbocharger and the modified consumption manifold nestle completely between the strut towers. Not solely has work been put into the engine’s positioning within the bay, however the turbo hints on the engine’s high-power construct.

HAZ00542

From the highest down, the 2JZ-GTE’s DOHC 24-valve cylinder head has been ported for max stream and options Brian Crower 264-degree camshafts, valve springs, and retainers. Bosch 1,500cc injectors provide gas, whereas Audi R8 ignition coils ship a robust spark. The engine exhales by means of a customized stainless-steel exhaust system, ending with OEM M3 quad suggestions.

HAZ00561

An Auto Verdi dry sump ensures constant lubrication throughout heavy cornering, whereas twin Bosch Motorsport 044 gas pumps within the boot complement the DeutschWerks 350 in-tank pump. A tried-and-tested mixture of 9:1 compression ratio DP solid pistons, Tomei solid connecting rods, and a model new OEM crankshaft means Wael’s 2JZ can reliably push 720whp.

HAZ00541-Edit

The drivetrain is suitably beefy; the Toyota/Getrag V160 6-speed gearbox has been upgraded with an OS Giken clutch, and runs a Samsonas tower shifter within the cabin. A customized prop shaft connects the transmission to an E39 BMW M5 limited-slip plated differential and driveshafts.

HAZ00538

Should you couldn’t inform by now, this isn’t a half-hearted construct, and the suspension and brakes have been upgraded accordingly.

The E46 rides on KW V3 coilovers with Powerflex polyurethane bushes throughout. Millway uni-ball camber prime mounts permit Wael to fine-tune the alignment, whereas Brembo 6-piston entrance and 4-piston rear callipers present severe stopping energy. Apex wheels in 18×10-inch sit in any respect 4 corners.

HAZ00547

The 328i can take such aggressive fitment as a result of the physique has been transformed to M3 spec. Wider M3 rear arches have been grafted on, complemented by M3 bumpers, mirrors, facet skirts, and entrance wings. The boot lid is a real M3 CSL merchandise, and the entire automobile is adorned with carbon fibre accents just like the diffuser, entrance lip, nook intakes, and inside trim.

Inside, Sparco Evo II seats safe the driving force and passenger with SCHROTH Racing 6-point harnesses, whereas the Sparco steering wheel ties in properly. For all its hardcore nature, small touches guarantee Wael’s E46 stays snug. A carbon fibre rear bulkhead minimises noise within the cabin and enhances the carbon fibre door playing cards.

HAZ00580-Edit

Even the Sparco seats have electrically adjustable bases, and the automobile retains a sunroof.

HAZ00575

I don’t assume an M3-spec E46 can ever be referred to as a sleeper, however licence plate apart, no clues reveal what Wael’s automobile hides beneath the hood. To me, that’s a improbable factor, because the E46 M3 is certainly one of my all-time favorite automobile designs.

HAZ00540-Edit

At a look, this 328i seems like an M3 you would possibly spot on the streets. A more in-depth have a look at the roll cage, Apex wheels, and substantial brakes could mark it out as a typical ‘Clubsport’ construct nowadays.

HAZ00585

But, this automobile is essentially a improbable chassis, elevated to M3 spec and past. Alternative upgrades tackle what could be an E46 M3’s Achilles’ heel: its S54 engine.

Is it my excellent E46? Hmm, I don’t assume so. I’m an excessive amount of of a purist. Objectively, nevertheless, is it the excellent E46? It’s actually a robust contender for the crown.
