K&N Air Filter Review: Real HP Gains or Marketing Myth on Modern JDM?

K&N cotton-gauze filters have been in JDM garages for four decades. We tested one on a B18C Integra and a 2JZ Supra to separate the real-world gains from the forum-lore exaggeration.

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)

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

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

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.

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

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

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

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

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 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 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

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 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

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

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

The EJ257 is the most-built Subaru turbo engine in history. It powered the Impreza WRX STI from 2004 through 2021, an almost 18-year production run that spans four chassis generations (GD, GR, GV, GJ). Along the way, it earned a reputation as both the most enthusiastically-modifi

Mitsubishi 4G63T: The Evolution Engine That Refused To Die

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

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
