2ZZ-GE engine info

[d_m_kolb]

The following information on Toyota's 2ZZ-GE engine is derived in large from the October issues of Sport Compact Car and Car and Driver. As always, I encourage you to obtain a copy for yourself. New to the ZZ engine family, the 2ZZ-GE engine achieves what the 1ZZ-FE could not. The 2ZZ-GE is a 1.8L (1796cc) all-aluminum in-line 4 equipped with Toyota's VVTL-i technology and a refreshing peformance G head design, developed once again in collaboration with Yamaha. The 2ZZ block is bored out from the 1ZZ's 79mm to 82mm, and the bores, instead of using thin-wall iron liners, use a metal matrix composite (MMC) with bonded-in ceramic fibers. The stroke is shortened from the 1ZZ's 91.5mm to a more rev-friendly 85mm. Next, the compression is pushed up to 11.5:1, and the piston skirts are coated with iron and tin for wear resistance. The end result is only 2cc's extra displacement but a whole different world in performance.2ZZ-GE Type: In-line 4, aluminum block and head Bore x stroke: 82.0 x 85.0mm Displacement: 1796cc Compression ratio: 11.5:1 Engine-control system: Toyota w/ multi-point EFI; AFM Ignition system: Electronic, with Toyota Direct Ignition system (TDI) Valve gear: Belt-driven dual overhead cams, 4 valves per cylinder, hydraulic lifters, variable intake and exhaust valve timing and lift Power (SAE net): 180bhp @ 7600rpm Torque (SAE net): 133lb-ft @ 6800rpm Redline / Fuel cut: 7800rpm / 8400rpm Ignition is accomplished by individual coils. No matter what you throw at it, this ignition system will probably take it – at least you better hope so because upgrading it may prove difficult.
