b20 thermostat..is it the same as the B18A1

From what i remember the timeing belt is different. is the thermostat
?

yes, everything is identical…even the timing belt from b20 to b18 a or b are the same. the gsr b18c is the only diff motor where the timing belt is diff, water pump, intake man etc are diff.

B18c GSR & Type-Rs are the same tooth count.

B16’s are different.

B18a/b and B20 are the same.

So there are three different belts for the different b-series motors.

well put unified:excite:

that would mean the waterpump too. Thanks guys. you are a great help.
