Mazda 20B-REW: The Three-Rotor Wankel That Powered the Cosmo Unicorn

The 20B-REW is one of the rarest production engines ever built. It's Mazda's **three-rotor Wankel** engine — essentially a 13B rotary with one extra rotor bolted on — and it appeared in exactly one production car: the 1990-1995 Eunos Cosmo, a luxury coupe sold only in Japan.

Nissan VQ35DE: The Wards 10 Best V6 That Powered Three Generations of Z Cars

The VQ35DE is the most-produced Nissan V6 of the 21st century. It's the 3.5-liter naturally-aspirated V6 that powered the 350Z Z33, Infiniti G35, Altima SE-R, Maxima, Murano, and over a dozen other Nissan and Infiniti vehicles from 2001 to 2018. It won **Wards 10 Best Engines** s

Nissan VQ37VHR: The VVEL-Equipped Evolution of the Legendary VQ V6

The VQ37VHR is the mid-2000s update to Nissan's VQ V6 architecture. Introduced in 2007, it added **VVEL** (Variable Valve Event and Lift) — a continuously variable valve lift system — to the proven VQ35DE platform. The result was a 3.7-liter V6 making 332 HP in the 370Z Z34 witho

Toyota 7M-GTE: The Forgotten Turbo Inline-Six That Preceded the 2JZ-GTE

Before the 2JZ-GTE, there was the **7M-GTE**. Toyota's first modern turbocharged inline-six production engine, introduced in 1986 for the Supra MK3 (A70 chassis), was the step between the 5M-GE (NA straight-six of the early 1980s Supra) and the 2JZ-GE/2JZ-GTE that powered the leg

Toyota 3S-GE BEAMS: The Altezza Engine That Revved to 7,700 RPM NA

The 3S-GE BEAMS is the final evolution of Toyota's legendary 3S-G family — a naturally-aspirated 2.0-liter inline-four with 5 valves per cylinder (Yamaha-influenced head), variable intake runners, and a 7,700 rpm redline. It's the engine that powered the Altezza RS200 (1998-2005)

Mitsubishi 4B11T: The Final Evo Engine That Replaced the Legendary 4G63T

When Mitsubishi launched the Lancer Evolution X in 2008, they faced an impossible task: replace the 4G63T, arguably the most successful turbocharged inline-four in rally history. The 4G63T had powered 4 consecutive WRC championships under Tommi Mäkinen and had a tuning ceiling th

Toyota 1JZ-GTE: The Smaller Twin-Turbo Inline-Six That Drift Scene Loves

The 1JZ-GTE lives in its bigger brother's shadow. When car enthusiasts say "JZ engine," 99% mean the 2JZ-GTE. But the 1JZ-GTE — Toyota's 2.5-liter twin-turbocharged inline-six, produced from 1990 to 2007 — is arguably the better drift engine, the more affordable tuning platform,

Honda C30A / C32B: The All-Aluminum NSX V6 Co-Developed by Ayrton Senna

When Honda introduced the NSX in 1990, they made a statement to the world: Japan could build a supercar. The C30A V6 at its heart was Honda's most technically ambitious production engine to date — all-aluminum construction, titanium connecting rods, VTEC valve control, and precis

Nissan VR38DETT: The Hand-Built Twin-Turbo V6 That Powers R35 Godzilla

The VR38DETT is Nissan's answer to the 21st century supercar. It's the engine at the heart of the R35 GT-R — a 3.8-liter twin-turbocharged V6 that's hand-built by a single Takumi (master engineer) at Nissan's Yokohama Plant, signed with a plaque, and capable of holding together a

Nissan VG30DETT: The 90s Twin-Turbo V6 That Powered the 300ZX Z32

The VG30DETT is the engine that almost everyone forgets when they list great Japanese twin-turbo powerplants from the 1990s. Overshadowed by the 2JZ-GTE, the RB26DETT, and the 13B-REW, it nonetheless powered one of the most beautiful Japanese sports cars of the era — the Nissan 3

Toyota 3S-GTE: The MR2 Turbo Engine That Beat the Competition Quietly

The 3S-GTE doesn't have the name recognition of a 2JZ-GTE or an RB26DETT. It hasn't been immortalized in Fast & Furious movies. But if you ask any Japanese touring car engineer what the most well-engineered 2.0-liter turbo four-cylinder of the 1990s was, they'll tell you it's the

Honda F20C: The 9,000 RPM S2000 Heart That Matched F1 Specific Output

When Honda revealed the F20C in 1999 — the 2.0-liter naturally-aspirated inline-four that would power the S2000 roadster — the specifications were almost unbelievable. **250 horsepower** from 1,997 cc, without forced induction. That's **125 HP per liter**, the highest specific ou

Honda B16B: The EK9 Civic Type R Heart That Made 185 HP From 1.6L

The B16B is the rarest and most revered small-displacement B-series VTEC engine Honda ever built. It existed in exactly one car: the 1997-2000 Civic Type R (EK9 chassis), sold only in Japan. Its factory power output of **185 PS** from **1.6 liters** equated to **115 HP per liter*

Honda B18C Type R: The Naturally-Aspirated Masterpiece That Revved to 8,400

The Honda B18C5 — the engine that sat under the hood of the USDM Integra Type R from 1997 to 2001 — made 195 HP from 1.8 liters of naturally-aspirated displacement. It revved to 8,400 rpm. It produced its peak power at 8,000 rpm. In an era when American V8s were making 250 HP fro

Honda K20A Type R: The 8,400 RPM Four That Redefined VTEC

When Honda introduced the K-series in 2001, they did something audacious: they reinvented VTEC. The B-series VTEC was already a legend — an abrupt, cam-swap system that made the Integra Type R sing. But the K-series introduced **i-VTEC** (intelligent VTEC), which added continuous

Toyota 4A-GE 20V Silvertop and Blacktop: The Corolla Engine That Revved to 11,000

The 4A-GE is the engine that turned a 1980s Corolla into a cult classic. When Toyota slotted the 4A-GE into the AE86 Corolla Levin/Trueno, they created the car that drift legend Keiichi Tsuchiya used to teach a generation how to slide. When they added a 20-valve head in 1995 (wit

Nissan SR20DET: The Drift Scene Engine That Defined a Generation

If you've ever watched a drift video, you've heard an SR20DET. The whistle of a T28 turbo spooling, the chirp of missed shifts, the bark of an open-element intake — that's the soundtrack of the SR20DET, the engine that powered virtually every iconic JDM drift car of the 1990s and

Mazda 13B-REW: The Twin-Rotor Turbo That Defied Convention

The 13B-REW is not a piston engine. It's a **Wankel rotary** — two triangular rotors spinning inside epitrochoid-shaped housings, with no reciprocating mass, no valves, no camshafts. Invented by Felix Wankel in the 1950s, perfected by Mazda across three decades of obsession, the

Toyota 2JZ-GTE: The Legendary Inline-Six That Rewrote Tuning History

The Toyota 2JZ-GTE isn't just an engine. It's a cultural artifact, a benchmark, and arguably the most over-engineered production four-stroke ever bolted into a road car. When Toyota engineer Isao Tsuzuki and his team set out to design the replacement for the already-potent 1JZ-GT

The 4G63T is the engine that won four consecutive World Rally Championships. It powered the car that made Tommi Mäkinen a four-time WRC drivers' champion. It's the reason a generation of tuners believed "1,000 HP from a 4-cylinder" was not only possible but regular. It's the engi
