A20

[tay_ang]

What exactly does A20, A21, B20 and whatever stand for.

i also have a good ideal of what OEM stands for but what does it actually stand for.

Thanks

A20, B20 and so forth are engine codes.

I'm not too sure what OEM means but I know it means 'stock crap' and not 'high performance'.

A is the Block series, 20 is for 2.0 liters
and OEM is Original Equipment Manufaturer

A20

A stands for the Engine series/Type

20 stands for the displacement= 2.0L

Edit, man you guys are fast

The letter in the begining is the series of motor the two numbers after refer to the engine's displacement in liters, on some honda engines theres one letter and one number after, for example: b18c and the b18c5 or b16a or b16a2.As far as my knowledge goes the c5 is the type R and the c is the gsr. As for the b16a and the b16a2, the a is jdm first gen b16 and the a2 is the usdm 3 gen motor. I could go on forever with this let me know if you want me to keep going.

b18c and the b18c5 or b16a or b16a2.As far as my knowledge goes the c5 is the type R and the c is the gsr.

I believe the gsr is B18C1, but yea. You've got the basic concept down. The numbers for the displacement and so on and so forth.

Okay maybe I messed up the c is jdm the c1 is usdm. I've seen several 00 gsr's with b18c's.

first letter = block series
first two numbers (##) = displacement
second letter = application
second number (#) = emissions information

I have info on the B18c6:

B18C6 version of the 1797cc engine:

Compression ratio = 11.1:1
Max power = 190PS @ 7900rpm
Max torque = 178Nm @ 7300rpm
Unleaded petrol 95 octane or higher
US-spec motors are designated as the B18C5, and the Australians use a B18C7 on their ITRs. JDM 98specRs simply have "B18C" as the motor designation.
