The Engine number is commonly used to identify the engine, statisitics,
power, modifications and more of your particular celica.
The chassis number can be loosely looked at as a 4+ combination
of numbers and letters. for simplicities sake, first start by looking
at the chassis number as a combination of four spaces.
1 2 - 3
The first space represents the engine generation located in the
car. For all Toyota engines this is the first number or pair of
numbers. Toyota designers base most of their engines of of previous
designs. For example if the first number is 7 (7A-FE), then it means
that there have been 7 versions of the engine series built off of
the first version.
The space designates the engine family that your engine is based
off of. All engines in the same series share the same basic block
and construction. This is always a combination of one or two letters.
Everything after the dash represents various properties of the
engine. The last space usually contains only two letters in FWD
Celicas. Earlier cars may have any of a number of combinations of
letters. some of the more popular letters are below
||Dual carbs ( non-twin cam engines
||Electronic Fuel Injection
||Fuel Efficient Head (narrow valve angle)
||Performance Head (wide valve angle)
||Single Point Fuel Injection
||Low compression for regular (not super or premium)
|| Swirl intake ports
||Direct injection & swirl pot pistons (starting
||Japanese pollution control
Thus looking at various chassis codes....
1 2 -
7A-FE = 7 A - FE
= 7th version of the A- series engine, fuel efficient head, EFI
3S-GTE =3 S - GTE=
3rd version of the S-series engine, performance head, turbo-charged,
22R-C =22 R - C
= 22nd version of the R- series engine, Carburated.
2ZZ-GE =2 ZZ - GE
=2nd version of the ZZ- series engine, performance head, EFI
