I owned a 90 Prelude SI,and there was a 2.0SI and a "SI";the difference was
that the "SI" had 140 HP(that's the one I had),and the 2.0SI had
135HP,though both were 2 liter motors.
I suspect most of those "Prelude SI" are the 2.0SI models,they were much
more common. ISTR that the 140HP motor was an all-aluminum motor,no iron
cylinder liners.

I don't recall the 90 SI as having anti-lock brakes,though.

I have a 1990 Prelude Si ALB with a JDM B20A engine in it. (Engine is not the original, of course) My ECU is a PK3, which is the original ECU from the factory, and the car runs fine. I've noticed that most 89-91 Prelude Si's have a PK2. Does anyone know the difference between the two types? Thanks! Jon
