The New 2JZ: A BMW S58 Engine With 1,000 Horsepower?
There is one engine that dominates all others when it comes to drift cars: the formidable Toyota 2JZ. One of the most widely used engines for drift and race cars is the turbocharged straight-six that powered the Mk4 Toyota Surpra. The reason for this is that it can produce 1,000 horsepower with reasonable ease and yet be reliable. The 2JZ is one of the most durable and easily tuneable engines on the planet. The BMW S58, a brand-new engine, might be able to compete with Toyota’s illustrious engine.
BMW’s 3.0 liter, twin-turbocharged inline-six S58 engine is used in the BMW M3, BMW M4, and X3 M, among other vehicles. Tuners quickly understood its enormous tuning potential following its introduction. It was soon discovered by fans and tuners that they could easily produce 1,000 horsepower from it after experimenting with it in drift vehicles.
To be used in their drift car, the Red Bull Driftbrothers sent their BMW M4 S58 engine to TDP.ie for tuning. The only things that were altered were the cylinder head’s geometry, the inclusion of port injection to complement the direct injection in the engine, and updated turbos. I’m done now. Everything else remains stock; nothing else was modified. So what improvements in performance were made?
The BMW S58 engine was able to produce 1,049 horsepower after being run on an engine dyno, which is absurd. It is simply crazy that it can produce that much power without making significant internal improvements. Its torque figure of 1,275 Nm (940 lb-ft) may have been even more astounding. from a six-cylinder, 3.0 liter engine. It’s amazing.
The fact that the engine hasn’t yet realized all of its potential makes it even more thrilling. The turbos were running a little too hot during the test runs because the cold air intake system wasn’t accessible, which slightly decreased performance. Imagine operating a vehicle with more than 1,000 horsepower, but it somehow feels lacking? We cannot. We’re happy that someone thought it necessary to tune an E58 engine to 1,049 horsepower, though.
S58
The S58, which took the place of the S55, was also based on its non-M counterpart, in this case the B58 single-turbo straight-six. The S58 debuted in 2019 with 480 horsepower in the F97 X3 M and F98 X4 M and 510 horsepower for the Competition variants before being added to the G8x M3 and M4 in 2021.
Higher compression is possible with the S58’s sleeve-free closed-deck design, which creates a highly robust crankcase. A wire-arc sprayed iron coating on the cylinder walls also helps to cut down on frictional losses and weight. The S58 features a light-weight forged crankshaft, and because of the remarkable torsional rigidity of the crankshaft drive and the reduction in rotating mass, the engine can rev more freely and handle larger power and torque outputs better. The cylinder head, on the other hand, has a core made using 3D printing. This process makes it possible to create geometric forms that are beyond the scope of traditional metal casting techniques. In addition to making the core lighter, it also made it possible to route the coolant ducts in a way that optimizes temperature control.
Two mono-scroll turbos, an indirect intercooler powered by a low-temperature circuit, and specialized compressors are used in the S58 to maximize the turbos’ output of power. The dual-flow air intake system’s pressure losses are decreased by a flow-optimized design, and the wastegate’s electronic management aids in improving turbo responsiveness. The engine features a modern, high-precision injection technology that allows for shorter injection times and more effective mixture preparation by injecting fuel at a maximum pressure of 350 bar into the combustion chambers. The S58 also features double-Vanos variable camshaft timing and Valvetronic variable valve timing.
A high-performance engine like the S58 requires effective cooling, and despite some debate over the G8x’s nose, the engine receives plenty of air thanks to all those massive intakes. The low-temperature radiator and high-temperature radiator are located behind the kidney grille in the center of the engine. Airflow is additionally fed by the horizontally positioned engine oil cooler and, in Competition models, a separate transmission oil cooler in the lower section. An electrically powered fan helps out when the requirement for cooling is greater and when the speed is low.
The low-temperature system’s electric coolant pump aids in maximizing the volume flow to the intercooler. A mechanical water pump, the primary radiator, and two additional remote radiators located in the wheel arches make up the high-temperature circuit. These components work together to cool the engine block and the two turbochargers. After the engine has been turned off, the turbocharger cooling might go on for a while with the help of an auxiliary electric water pump. Finally, track driving has been taken into consideration when designing the oil supply system. The map-controlled oil pump may draw lubricant from the smaller chamber through an auxiliary suction stage, which fills in when more capacity is required. The engine’s weight-minimized sump includes two distinct chambers and an integrated suction channel. This guarantees that the S58 always receives a steady flow of oil, even during hard acceleration and cornering.
The variant used in Competition versions produces 510 horsepower at 6250 rpm while its torque peak of 479 lb ft stretches from 2750-5500 rpm; the S58’s redline is at 7200 rpm. The S58 produces 480 horsepower at 6250 rpm with its 405 lb ft torque peak available from 2650-6130 rpm.
Is the BMW S58 Engine the Start of a Legend?
The S58 is constructed around BMW’s B58 modular engine, as suggested by its name. Since its release in 2015, the B58 has been found in practically all BMW vehicles until 2019—including the newest 5 and 7 Series vehicles, the new 3 Series, and the X7. It’s shared with the Toyota Supra and is also available in the most recent Z4, where it powers a select M-badged vehicles like the Z4 M40i, M340i, M140i, and M240i. As you may have seen, full-fledged M vehicles don’t utilize the B58 norm.
That’s because engines used in cars like the M3, M4, and M2 Competition are powered by the S55, a high-performance variant of BMW’s venerable N55 unit, which is currently being phased out. The new S58, which will completely replace the S55, steps in to help with that.
Although it’s not a completely new engine, the S58 ups performance and makes it possible for M-badged BMWs to meet ever-tougher emission standards. This latter problem grew significantly for the S55. Due to the current sedan’s inability to meet the Worldwide Harmonized Light Vehicles Test Procedure’s new emissions requirements, BMW stated in early 2018 that it would stop producing the M3 in May. (WLTP). BMW decided to wait for the S58 since the current M3 specifically needs a particulate filter and installing one on the S55 involves extensive re-engineering. This new device will continue to be compatible for a number of years and has all it needs to pass WLTP rules.
The S58 also offers a significant increase in power. It is the most potent six-cylinder gasoline engine BMW has produced to date, with ratings of 503 horsepower in the Competition variants and 473 horsepower and 442 pound-feet of torque in the new X3 M and X4 M. There isn’t a pre-generation X3 M to contrast it with, but we can consider the S55 that was available in the M3 and M4. The regular S58 outperforms the normal M3 and M4 by 55 horsepower and 36 pound-feet, and it surpasses the M3 CS by 26 horsepower. With 493 horsepower and 443 pound-feet, the M4 GTS’s engine continues to be the best, although the Competition model of the S58 produces 10 more horsepower, for a total of 503 horsepower. Furthermore, it is reasonable to believe that there is still much room for development.
BMW’s decision to stop producing the naturally aspirated S65 V-8 engine in the S55 left enthusiasts fuming, but the S58 will finally make them forget about it.

The BMW B58 engine’s dependability.
Although B58 coolant loss seems to be a common issue, it typically only causes minor issues. If you occasionally top off tiny amounts, don’t worry about it. As the B58 ages, it’s important to keep an eye on it. Disintegrated oil filters are a common occurrence, however they are typically not dangerous. Although there have only been a few VANOS and valve cover oil leaks so far, these problems are likely to continue.
It’s difficult to predict what issues on the B58 might become widespread as it ages, as we said earlier. It is currently proven to be a dependable engine and a significant upgrade over the N54 and N55. There are a few service bulletins and recalls for the B58. A small number of B58s from the first production run have crankshaft guide bearing problems. It is so few that it hardly merits mentioning. Any engine will eventually develop some flaws, and the B58 is no different. However, the B58 has had a strong beginning in terms of performance and dependability.
