Greddy / Trust: The Intercooler Giant That Redefined Japanese Tuning

Greddy (スタートラスト Trust Co., Ltd. in Japan) is, next to HKS, the most commercially successful Japanese aftermarket tuning company in history. Founded in 1977 as "Trust" (トラスト), the company later adopted the **Greddy** brand name for international markets. Greddy's specialty is forc

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*

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 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

Subaru EJ257: The Boxer Turbo Behind the STI Dynasty

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

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

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
