What engine did they have?? was it the A20??

 

b20a3? My 89 si has the b20a5 which is a DOHC rated at 135hp. the 88-90's shared this motor. the S i think had a sohc 2.0 which I THINK is the b20a3. There is also a b21a1, which is 140hp that came in the 4ws models.

 

88-90 2.0S = B20A3 Dual Carb SOHC
88-91 2.0Si (including 4WS for 88-89 only) = B20A5 DOHC
90-91 Si (including ALB and 4WS for 90-91 only)= B21A1 DOHC

and the A20A was in the 86-87 2.0Si's and some 86-89 Accords
