Welcome to COROLLA Performance

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.

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.

The 2ZZ-GE engine, mated to a 6-spd manual FWD transaxle, debuts in the 2000 Celica GT-S (ZZT23x):

 

A force to be reckoned with, this Celica and the 2ZZ-GE will very likely have strong aftermarket and TRD support.  To remind ourselves that this is still a COROLLA site, let's all envision a 2ZZ-GE ZZE110 Corolla... =)
