i was wondering what kind of car had a b16a2 1.7 liter v-tec, its from a honda civic si but i dont know what year.

the b16a2 is a 1.6L, and it came from the '99-'00 Si.

The only 1.7L vtec motor was the B17 from early gsr integra's, 92-93 I think, not sure.

^ Yup And the SOHC '01-'02(?) Civic EX

I thought the 2000+ EX had a 1.7L. Humm.... maybe im wrong.

It's the '01+ EX. I wasn't sure if they were still the 1.7L after '02, hense the (?) I put in there. But the '00 EX is the same one as the '99 (maybe the '96-'00?). '01 is when they started changing things again.
